Center, T.D.; Wright, A.D. Lanham, Md. : Entomological Society of America; 1991 Feb. Environmental entomology v. 20 (1): p. 323-334; 1991 Feb. Includes references. Language: English Descriptors: Eichhornia crassipes; Neochetina eichhorniae; Leaves; Plant analysis; Age; Phenols; Attractants; Weed control; Smell; Biological control Abstract: Behavior of the weevil Neochetina eichhorniae Warner, a specialist herbivore, varied with leaf age of waterhyacinth (Eichhornia crassipes (Mart.) Solms-Laubach [Pontederiaceae]). In the field, adult feeding decreased as the leaves aged. Accrued feeding damage on 8-d-old leaves was only about 60% of the sum of two respective sets of 4-d-old leaves. Likewise, on 40-d-old leaves the accrued feeding damage was only 21% of that from 10 successive 4-d-old sets. Laboratory studies confirmed a preference for the youngest tissue available and discounted the influence of leaf arrangement. The weevils preferred unfurling bud leaves by a 5-fold margin over open immature leaves. Olfactometer studies showed a 2.4-fold greater attraction to young leaves than to mature leaves. Further, adult feeding exhibited under- dispersed patterns on young leaves but random distributions on old leaves. In contrast, a generalist, the yellow woollybear, Spilosoma virginica (F.), preferred mature waterhyacinth leaves and 14-d-old larvae weighed 85% less when provided young leaves instead of mature leaves. The youngest leaves were higher in N, P, K, and Mg, but low in Ca and Mn compared with older leaves. Total phenolics (compounds reduced by Folin reagent) were also highest in young tissue, but analyses of leaf extracts by thin-layer chromatography and high- performance liquid chromatography showed lowest concentrations of phenolic compounds in the youngest leaves. These data suggest that natural plant products, not necessarily phenolics, attract the weevils to young tissue and stimulate them to feed, especially at sites of previous injury. These constituents also might deter generalists like S. virginica, forcing them to consume only mature foliage. 17 NAL Call. No.: QH76.5.H3C6 Alien plant management by biological control.

New York, N.Y. : Plenum Press; 1990 Sep. Journal of chemical ecology v. 16 (9): p. 2747-2754; 1990 Sep. Includes references. Language: English Descriptors: Euphorbia prostrata; Allelopathy; Cynodon dactylon; Soil analysis; Bioassays; Biological control Abstract: Field observations indicated that Euphorbia prostrata strongly interferes with Cynodon dactylon (L.) Pers. Analysis of some physical and chemical soil factors indicated that competition was not the dominant factor of that interference. Soil collected from under E. prostrata stands was very inhibitory to seed germination and seeding growth of some of the test species including C. dactylon. This suggests the presence of inhibitory compounds in soil of E. prostrata stands. Subsequent experiments showed that aqueous extract, decaying residues, and root exudates of E. prostrata were inhibitory to most of the test species including C. dactylon. Thus, it appears that allelopathy is the major component of the interference, with competition probably accentuating its effect. It also was found that allelopathy is an important component of the interference by E. prostrata against Amaranthus retro-flexus, Medicago sativa, and Gossypium hirsutum. 20 NAL Call.

Language: English Descriptors: California; Triticum aestivum; Crop weed competition; Biological control; Amsinckia intermedia; Weed control; Biological control organisms; Anguina; Evaluation; Linear models; Mathematical models; Screening tests; Plant density; Plant parasitic nematodes Abstract: Methods for evaluating the efficacy of potential classical biocontrol agents were outlined for a model biocontrol agent-weed-crop system. A proposed biocontrol agent (the fiddleneck flower gall nematode), its weed host (coast fiddleneck), and wheat were used as representative organisms. An additive experimental design (inverse linear model) was used. Regression of the reciprocal of the overage plant biomass of each species onto the density of itself and the other plant species yielded competitive indices that measure the competitive ability of the plants. The results of 2 yr of field experiments revealed a dramatic change in the competitive interaction between fiddleneck and wheat due to the nematode. During the 1986-87 season in the absence of the nematode, fiddleneck intraspecific competition was 33 times stronger than interspecific competition with wheat. In the presence of the nematode, intra- and interspecific competition of fiddleneck were nearly equal. Only the coefficients that measure interspecific competition changed significantly in the presence of the nematode while the coefficients for intraspecific competition did not. 22 NAL Call.

Champaign, Ill. : Weed Science Society of America; 1989 Nov. Weed science v. 37 (6): p. 778-783; 1989 Nov. Includes references. Language: English Descriptors: Triticum aestivum; Crop weed competition; Amsinckia intermedia; Biological control; Weed control; Biological control organisms; Anguina; Evaluation; Path coefficients; Yield components; Fecundity; Plant parasitic nematodes; Plant density Abstract: Path analysis was used to assess the efficacy of the fiddleneck flower gall nematode as a weed biocontrol agent of coast fiddleneck in competition with wheat during 2 yr of field experiments. The path analysis revealed that the number of inflorescences/plant for fiddleneck and the number of heads/plant for wheat were the most important yield components that determine fecundity and seed yield. The density of fiddleneck had a much greater impact on the yield components of fiddleneck than did the density of wheat or the nematode rate of inoculation. The nematode had its greatest negative impact on the number of seeds/flower of fiddleneck and its greatest positive impact on the number of heads/plant of wheat. Path analysis predicts that a biocontrol agent that has a large negative direct effect on the number of inflorescences/plant for fiddleneck would be more efficacious in decreasing fecundity and seed yield than an agent that only impacts the number of flowers/ inflorescence, seeds/flower, or biomass/seed. 23 NAL Call.

Prior to the 1970's virtually no work was being conducted in this specialized area. Since that time the US Army Engineers (USAE) has been given the added responsibility of maintaining weed-free waterways by non-chemical alternatives. The Biomanagement Team at the USAE Waterways Experiment Station and the University of Florida have established programs to study biological control of aquatic weeds using plant pathogens. Hundreds of microorganisms have been evaluated for their potential as biological control agents of waterhyacinth, alligatorweed, eurasian watermilfoil, hydrilla, algae, and numerous other aquatic weeds. As a result, several fungal and viral diseases of these troublesome aquatic plants have been identified. Information will be presented on current efforts in the development of these plant pathogens for aquatic weed management. 57 NAL Call. No.: SD112.F67 Biological control of broom in New Zealand.

Language: English Descriptors: Texas; Datura stramonium; Datura ferox; Curculionidae; Weed control; Biological control agents Abstract: The weevil Trichobaris bridwelli Barber is a natural enemy of jimsonweed (Datura stramonium L.) in the southern United States. The temporal distribution of all life stages showed that T. bridwelli is bivoltine in central Texas and overwinters principally in the adult stage inside the seed capsules of jimsonweed. Females oviposited in the leaves, flowers, and capsules. Subsequent development occurred both in the stems and capsules of its host plant. All life stages of T. bridwelli were attacked by hymenopterous parasitoids; Anaphes sp. and Microctonus sp. are new host records. In the laboratory, adult females lived an average of 16.1 wk and deposited an average of 324 eggs. Development in the laboratory required 37.8 d: egg 5.9 d, larval stage 20.2 d, prepupal period about 3 d, and pupal stage 8.7 d. The intrinsic rate of increase (r(m)) of T. bridwelli was calculated from laboratory life table data to be 0.41 at 24 degrees C. T. bridwelli was evaluated for its potential effectiveness as a biological control agent of jimsonweed and possibly chinese thornapple, Datura ferox L. Although T. bridwelli did not complete development on a critical test plant (tobacco) under laboratory conditions, extensive host specificity testing should be conducted to determine the limits of its host range. 104 NAL Call.

Language: English Descriptors: Weed control; Plant pathogens; Biological control; Biotechnology; Genetic engineering Abstract: Plant pathogens have rarely been successfully used as biocontrol agents of weeds. One reason for this is that they are usually not lethal enough at low concentrations. In addition, they are usually not host specific. Our approach has been to mutate lethal broad host-range pathogens to obtain isolates that are still lethal to target hosts, but reduced in host range, survival capacity, or otherwise biologically contained. Two such types of biological containment are presented in a fungus, Sclerotinia sclerotiorum, a lethal pathogen of 40 different weeds. 106 NAL Call.

Washington, D.C. : American Society for Microbiology; 1990 Jun. Applied and environmental microbiology v. 56 (6): p. 1649-1655; 1990 Jun. Includes references. Language: English Descriptors: Missouri; Soil bacteria; Rhizosphere; Weeds; Seedlings; Plant pathogens; Phytotoxicity; Biological control Abstract: Rhizobacteria were isolated from seedlings of seven economically important weeds and characterized for potential phytopathogenicity, effects on seedling growth, and antibiosis to assess the possibility of developing deleterious rhizobacteria as biological control agents. The abundance and composition of rhizobacteria varied among the different weed species. For example, fluorescent pseudomonads represented from 11 to 42% of the total rhizobacterial populations from jimsonweed and lambsquarters, respectively. Other bacteria frequently isolated were nonfluorescent pseudomonads, Erwinia herbicola, Alcaligenes spp., and Flavobacterium spp. Only 18% of all isolates were potentially phytopathogenic, based on an Escherichia coli indicator bioassay. However, the proportion of isolates that inhibited growth in seedling assays ranged from 35 to 65% depending on the weed host. Antibiosis was most prevalent among isolates of fluorescent Pseudomonas spp., the activity of which was due to siderophore production in over 75% of these isolates. Overall, rhizobacterial isolates exhibited a complex array of properties that were inconsistent with accepted definitions for plant growth-promoting and deleterious rhizobacteria. It is suggested that for development of effective biological control agents for weed control, deleterious rhizobacteria must be screened directly on host seedlings and must possess several properties including high colonizing ability, specific phytotoxin production, and resistance or tolerance to antibiotics produced by other rhizosphere microorganisms, and they must either synthesize or utilize other bacterial siderophores. 114 NAL Call.

Dennill, G.B.; Gordon, A.J. Lanham, Md. : Entomological Society of America; 1990 Feb. Environmental entomology v. 19 (1): p. 130-136. maps; 1990 Feb. Includes references. Language: English Descriptors: South Africa; Australia; Acacia longifolia; Hymenoptera; Weed control; Biological control Abstract: The gall wasp Trichilogaster acaciaelongifoliae Froggatt (Pteromalidae) was released at 136 sites throughout the distribution area of the weed Acacia longifolia (Andrews) Willdenow in the Cape Province and Natal, South Africa. Each site was monitored annually to determine whether the wasp would establish and to determine its effectiveness where it had established. T. acaciaelongifoliae did establish throughout the range of A. longifolia. In the cooler coastal regions of the southwestern Cape and southern Cape, the wasp established well and levels of infestation were consistently high. However, in the hotter inland valleys and west coast of the southwestern Cape Province, and in Natal, establishment was poor and infestation levels were consistently low. In Australia, A. longifolia occurs naturally along the coastal regions of southern Queensland, New South Wales, Victoria, and eastern South Australia. However, the T. acaciaelongifoliae individuals released in South Africa originate only from the coastal regions of New South Wales and Victoria, and Tasmania. Climatically, these areas correspond most closely to the regions in which the wasp is most successful in South Africa. The method whereby the insects were released in South Africa, and the methods for evaluating the degree of establishment and subsequent infestation levels at each release site, are described. 120 NAL Call.

Washington, D.C. : American Society for Microbiology; 1989 Sep. Applied and environmental microbiology v. 55 (9): p. 2326-2332. ill; 1989 Sep. Includes references. Language: English Descriptors: Myriophyllum spicatum; Aquatic weeds; Fungi; Biological control organisms; Colonizing ability Abstract: A laboratory assay to assess colonization of a submersed aquatic plant, Eurasian water milfoil (Myriophyllum spicatum), by fungi was developed and used to evaluate the colonization potential of Colletotrichum gloeosporioides, Acremonium curvulum, Cladosporium herbarum, Aureobasidium pullulans, a Paecilomyces sp., and an unidentified sterile, septate fungus. Stem segments of plants were first immersed in suspensions of fungal propagules for 24 h and then washed to remove all but th tightly attached component of the population. Inoculationd was followed by two growth cycles of 3 days each. At the start of each cycle, washed plants were transferred to a mineral salts medium to provide an opportunity for the attached fungal populations to grow. After each growth period, plants were again washed, and fungal populations in the medium (nonattached), loosely attached and tightly attached to the plant, and within the plant (endophytic) were assayed by dilution plating. The fungi differed in the extent to which they attached to water milfoil and in their ability to grow in association with it. There were relatively few significant differences among the tightly attached fungal populations after 24 h, but growth of the better colonizers led to a greater number of significant differences after 4 and 7 days. In addition, the better colonizers showed sustained regrowth of loosely and nonattached fungal propagules in the face of intermittent removal by washing. A milfoil pathogen, C gloeosporioides, was the only endophytic colonizer; it was also among the best epiphytic colonizers but was not demonstrably better than A. curvulum, a fungus commonly found as an epiphyte on watermilfoil. The yeastlike hyphomycete Aureobasidium pullulans was the only fungus that consistently failed to establish an increasing population on the plant. 121 NAL Call.

Language: English Descriptors: Sesbania exaltata; Colletotrichum truncatum; Fungal spores; Mycoherbicides; Biological control agents; Cell culture Abstract: Four culture systems were compared: (1) dialysis membranes (MF), (2) liquid shake flasks (LF), (3) solid particles with humidity control (SFC), and (4) solid particles without humidity control (SFE). A Plackett-Burman fractional factorial experimental design was employed with 10 total variables. Eight media components, plus two levels of inoculum, were tested in all systems. Other variables were light vs. dark for MF, agitation level for LF, vermiculite vs. rice hulls for SFC, and particle size for SFE. High yeast extract (1 g/l) produced more (P < 0.01) spores than low (0.3 g/l) for all culture systems. Carbohydrate (sucrose) at 20 g/l produced more spores than at 40 g/l for SFC. MgSO4.7H2O at 2 g/l was better than none for LF and SFC. For MF, LF, SFC, and SFE, respectively, the overall average numbers of spores per ml of medium were 0.53, 0.72, 0.28, and 0.073 X 10(7), while the highest numbers of spores were 1.25, 2.75, 1.52, and 0.46 X 10(7). Thus, the method of production cannot be decided at this stage but must await further studies of recovery and storage. 125 NAL Call.

Language: English Descriptors: Cassia obtusifolia; Datura stramonium; Weed control; Biological control; Alternaria crassa; Alternaria; Mycoherbicides; Inoculum density; Infection; Conidia; Emulsions Abstract: Fungal spore infectivity on leaves is a function of environmental factors (duration of dew point humidity, temperature), the defense mechanisms of the host plant, and fungal pathogenicity. The inoculum threshold of thousands of spores per square centimeter of leaf surface or tens to hundreds of spores per droplet has been expected and accepted. Evidence is presented that the high threshold concept does not hold with Alternaria cassaie and A. crassa, as one spore per 2- microliter droplet was sufficient to infect plants of Cassia obtusifolia and Datura stramonium, respectively, when the droplet was an invert emulsion containing a 1-microliter mixture of oils and waxes on the outside and 1 microliter of water, sodium alginate, and conidia on the inside. The intensity of infection always was enhanced by the emulsion. Even a culture of A. cassiae that lost its infectivity, giving only a hypersensitive response when applied in water, became infective in the invert emulsion. 127 NAL Call.

Test plot data for the years 1981 through 1988 from the Purdue University Agronomy Farm, which has highly productive, well-drained soils, were analyzed. Net incomes for no-till tillage systems on all farms in the model were consistently and significantly lower than incomes for moldboard and chisel plow tillage systems due to slightly lower yields and substantially higher herbicide costs. Generally, net farm incomes were slightly higher with a moldboard plow versus chisel plow tillage system. Also, as farm size increased, per hectare net incomes increased. About 80% of the time under moldboard or chisel plow tillage systems, the model chose as optimal the lowest of three herbicide application rates. A corn/soybean rotation was chosen as optimal on 56% of the farm area analyzed, versus 25% for continuous corn and 13% for a corn/soybean/wheat rotation. 158 NAL Call.

Language: English Descriptors: Hawaii; Clidemia hirta; Thysanoptera; Weed control; Biological control Abstract: The effectiveness of Liothrips urichi Karny introduced to control the noxious weed Clidemia hirta (L.) D. Don was studied at three sites on Oahu, Hawaii. Vegetative C. hirta infested with L. urichi showed greater mortality after 1 mo and significantly shorter internode diameters among the survivors at 4 mo than uninfested plants. L. urichi had no effect on plant height in the field but stunted the growth of young potted C. hirta in greenhouse studies and caused a significant increase in terminal leaf drop. No effect on production of floral buds, flowers, or berries occurred at any field site over 11 mo. L. urichi was restricted to sunny or partly sunny sites and never occurred in heavily shaded areas. Higher thrips infestations occurred during the fall and winter and lower infestations during the summer. Percentage of damaged tips also fluctuated seasonally, but the degree of damage to individual leaves was not seasonal. 165 NAL Call.

Language: English Descriptors: North Carolina; Arachis hypogaea; Diabrotica undecimpunctata howardi; Weeds; Tyrophagus putrescentiae; Predators of insect pests; Biological control agents Abstract: The below-ground effects of weeds (Amaranthus retroflexus L., Chenopodium album L., Ambrosia artemisiifolia L., Digitaria sanguinalis L., Setaria viridis L., Panicum dichotomiflorum Michx.) and increased soil moisture on damage to peanut pods by southern corn rootworm, Diabrotica undecimpunctata howardi Barber, was investigated in a 2-yr field and greenhouse study. Field experiments demonstrated that weedy areas had less pod damage overall and higher predator numbers than nonweedy areas. However, increased soil moisture, which increased southern corn rootworm oviposition and egg and larval survival, confounded the results. Greenhouse studies showed that three broadleaf species and three grass species were not as good food sources as peanuts for southern corn rootworm larvae. Although the presence of weeds growing with peanuts did not lower larval survival, weeds did significantly (P less than or equal to 0.05) slow larval developmental rate. In greenhouse studies, damage to peanut pods was approximately 66% in peanut-only (control) treatments, 55% in peanut + weed treatments, 32% in peanut predator treatments, and 9% in peanut + weed + predator treatments. The interaction of predators and weeds in lowering the amount of damage caused by southern corn rootworm was significant (P less than or equal to 0.05). Field and greenhouse experiments demonstrated that at least two factors were operating to reduce pest damage in this below-ground, multispecies plant association. Predators and the structural complexity of the weed-crop root association may be working synergistically to reduce southern corn rootworm damage to peanuts. 167 NAL Call.

Lanham, Md. : Entomological Society of America; 1992 Feb. Environmental entomology v. 21 (1): p. 94-102; 1992 Feb. Includes references. Language: English Descriptors: Colorado; Artemisia tridentata; Biological control; Brush control; Anabrus simplex; Biomass; Ecosystems; Ground cover plants; Rangelands; Undergrowth Abstract: The effects of herbivory by the Mormon cricket, Anabrus simplex Haldeman (Orthoptera:Tettigoniidae), and removal of sagebrush (Artemisia tridentata Nutt.) on understory plant biomass production and cover were determined. Averaged over a 3-yr period, 50-75% removal of sagebrush resulted in an approximately 20% increase in summer understory biomass production; understory plant cover was not affected by sagebrusb removal. Mormon crickets, at densities of four and eight crickets per square meter during a 5-wk period, did not significantly affect understory plant biomass production but did reduce forb and total vegetative cover. Mormon cricket herbivory and sagebrush removal were independent with respect to their effects on understory vegetation. Furthermore, the incomplete removal of sagebrush did not affect the feeding ecology of Mormon crickets. Analysis of cricket crop contents suggested that sagebrush was fed upon predominantly; there was little dietary overlap between crickets and cattle. As long as some sagebrush is left intact (e.g., 25%), sagebrush control programs are unlikely to influence Mormon cricket diet selection or damage potential. Cover estimates, which are commonly used by ranchers and rangeland managers to estimate forage availability, provide deceptive assessments of cricket effects, untimely perhaps leading to an undeserved reputation as a rangeland pest. 171 NAL Call.

Language: English Descriptors: Louisiana; Saccharum officinarum; Diatraea saccharalis; Digitaria sanguinalis; Solenopsis invicta; Aldicarb; Nematode control; Integrated pest management Abstract: Weeds in a Louisiana sugarcane field increased the abundance of arthropod prey and predators (including the imported fire ant), and caused at least 25% less injury from sugarcane borer, Diatraea saccharalis (F.). Weed competition, however, reduced sugarcane biomass, stand density, and sugar yields. Without insecticidal control of sugarcane borer, weedy habitats were more profitable than weed-free habitats. Future study on weed conservation in the furrows alone is suggested. Spring aldicarb (nematicide-insecticide) applications reduced arthropod prey, particularly stylet-feeding herbivorous insects, for up to 10 wk, Regardless of weed cover, predator densities on the soil surface, weeds, and cane stalks were decreased by the nematicide, and percentage of internodes injured by sugarcane borers increased by at least 19%. Fenvalerate (insecticide) reduced predators and prey arthropods on the soil surface and cane stalks, including Solenopsis invicta Buren. Cicadellidae on cane foliage were reduced by the insecticide, but the yellow sugarcane aphid, Sipha flava (Forbes), was enhanced by 63%. Fenvalerate did provide at least 70% protection against the sugarcane borer, with ratoon crop sugar yields 8.7% greater than in the insecticide-free regimes. A combination of weed and sugarcane borer chemical control tactics was the most economically sound pest management strategy. 172 NAL Call.

Language: English Descriptors: Quebec; Convolvulus arvensis; Seedlings; Biological control; Weed control; Biological control organisms; Phomopsis; Inoculum; Density; Conidia; Growth retardation; Growth stages Abstract: Phomopsis convolvulus Ormeno, a fungus, reduced growth and regeneration of field bindweed under greenhouse environments. Field bindweed seedlings at the cotyledon stage were severely injured and killed (95% mortality) with 10(8) conidia/m2. Three- to five-leaf seedlings (2 weeks old) were controlled when inoculated with 10(9) conidia/m2 (70% mortality; 98 and 89% reduction in dry weight of aboveground biomass and roots, respectively). This inoculum density reduced aboveground and root biomass, and adversely affected regeneration of 4-week-old seedlings and established plants, but few plants were killed. In controlled-environment studies, two inoculations were superior (P = 0.02) to one inoculation in reducing foliage aboveground of well-established seedlings (4 weeks old). However, new shoots produced between the first and second inoculation treatments were less diseased than expected. 173 NAL Call.

Language: English Descriptors: Montana; Cirsium arvense; Weed control; Biological control; Biological control agents; Ceutorhynchus litura; Dispersal; Larvae; Injuries; Shoots; Regrowth Abstract: Ceutorhynchus litura dispersed 9 km in 15 yr from its point of release in 1972 with incident of infestation of Canada thistle plants at one study site reaching 92% in 1987. Plants generally survived larval feeding in the spring, but holes created by departing larvae provided entrances for arthropods, nematodes, and diseases. Subsequent mortality rates were high for belowground Canada thistle shoots. However, the number of new shoots from underground roots the following spring usually offset the mortality that had been indirectly caused by C. litura. 179 NAL Call.

Lanham, Md. : Entomological Society of America; 1991 Aug. Environmental entomology v. 20 (4): p. 1187-1194; 1991 Aug. Includes references. Language: English Descriptors: Greece; U.S.A.; Centaurea solstitialis; Curculionidae; Weed control; Biological control agents Abstract: The host specificity of Eustenopus villosus (Boheman) was studied in the laboratory using field-collected adults from Greece arid overwintered progeny of these adults. No- choice and two-choice host specificity tests were carried out in the laboratory. Thirty-four plant species, in addition to yellow starthistle (Centaurea solstitialis L.) (as the control) from Greece and the United States, were tested. Under no- choice test conditions in the laboratory, adults showed to some degree a rather broad feeding spectrum but with heaviest feeding on yellow starthistle. Oviposition was restricted to some species in the genus Centaurea, with heaviest oviposition on yellow starthistle. Under two-choice conditions (test plant caged with yellow starthistle control), oviposition occurred only on yellow starthistle. The literature on field hosts and host specificity tests indicate a high level of larval host specificity to yellow starthistle. A laboratory study showed that the combined effects of adult and larval feeding on yellow starthistle can reduce seed production by 98.8% under laboratory conditions; this also indicates that the species has excellent potential as a biological control agent. 180 NAL Call.

Language: English Descriptors: South Carolina; Ipomoea batatas; Allelopathy; Cyperus esculentus; Weed control; Biological control; Competitive ability; Crop weed competition; Roots; Growth rate; Inhibition; Plant extracts; Periderm; Crop yield; Tubers Abstract: In field studies, 'Regal' sweet potato greatly reduced yellow nutsedge growth when the two species were grown together using standard cultural practices. At the end of the growing season, yellow nutsedge shoot dry weight per m2, in plots where the two species were planted together was less than 10% of shoot weight in plots where nutsedge was grown alone. Presence of yellow nutsedge did not markedly affect sweet potato growth. When grown together in a greenhouse experiment designed to minimize the competitive effects of sweet potato on yellow nutsedge, yellow nutsedge growth was reduced more than 50% by sweet potato 8 and 12 weeks after planting. The most polar fraction of serially extracted sweet potato periderm tissue was highly inhibitory to yellow nutsedge root growth. These results indicate that sweet potato interference with yellow nutsedge under field conditions is partially due to allelopathy. 184 NAL Call.

Language: English Descriptors: Weed control; Mycoherbicides; Herbicide mixtures; Formulations; Biological control; Chemical control Abstract: Fungal weed pathogens (mycoherbicides) are difficult to formulate into effective products because, as living organisms, their viability must be preserved throughout processing and storage. Furthermore, the pathogens, as packaged in a final product, must be able to control weeds after application under natural environmental conditions of moisture and temperature. This overview of formulation and application technology for microbial weed control describes the current developmental status of experimental and commercial products. A brief review of combinations of mycoherbicides with chemical pesticides and beneficial insects is included. 197 NAL Call. No.: QH301.A76 Formulation requirements for biological control agents.

Leaf injury from Et was the most extensive. Johnsongrass was equally or more susceptible to these fungi 7 days after emergence (DAE) than at 14, 21, or 28 DAE. The greatest leaf injury, more than 90%, was induced by Et with 2 x 10(5) conidia/ml and a 24-h dew period. Sequential inoculation with Et at 15 and 20 DAE resulted in injury to more leaves than a single inoculation 15 DAE. No synergistic or antagonistic effects were observed in combinations of Et with Gs or Cg. Injury was limited to exposed leaves and sheaths, injured seedlings resumed growth and developed new leaves. Development of new leaves from inoculated plants was reduced by 30% or less at 14 days after inoculation (DAI) compared to uninoculated plants. Inoculation with Et or Bh was not as effective as paraquat or sethoxydim, since treatment with both herbicides resulted in seedling death. Seedling kill was not observed in any fungal tests. 199 NAL Call. No.: SD112.F67 Fungi as potential biological control agents of weeds in New Zealand. Johnston, P.R. Rotorua : The Institute; 1990.

Language: English Descriptors: Hardwoods; Stumps; Weed control; Sprouting; Biological control agents; Chondrostereum purpureum Abstract: Cultures of the fungus Chondrostereum purpureum (Fr.) Pouzar were applied to cut surfaces of hardwood stumps immediately after the trees were felled in late spring and summer and the stumps monitored for fungus infection and adventitious sprouting during the ensuing 2 years. Hardwood species inoculated were red maple, sugar maple, yellow birth, paper birch, pin cherry, trembling aspen, and beech. The fungus was applied as wheat bran cultures in a mineral oil slurry or by inverting petri dish cultures on the stump. All treatments resulted in development of sporophores of the fungus on the stump within 2 years and a concomitant reduction, as compared to the uninoculated controls, of the number of stump sprouts. The speed of stump invasion by the fungus and reduction of sprouting varied both among and within species. The feasibility of using this fungus as a biological control of regrowth after stand cleaning is discussed. 202 NAL Call.

Includes references. Language: English Descriptors: Plant pathogenic fungi; Mycoherbicides; Weed control; Genetic variation Abstract: Successful use of a fungal pathogen as a bioherbicide is dependent on the genetic make-up of both the fungus and its target weed. The genetic stability and variability of each must be carefully considered prior to commercial use. The weed host may consist of a genetically heterogeneous population and vary in susceptibility to the biocontrol agent within its geographic range. Fungal pathogens can vary in several important characteristics such as sporulation, virulence, host range, or tolerance to environmental extremes. Specific examples will be used to illustrate the advantages and disadvantages of genetic variability in biological weed control. 206 NAL Call.

Rockville, Md. : American Society of Plant Physiologists; 1992 Feb. Plant physiology v. 98 (2): p. 654-659; 1992 Feb. Includes references. Language: English Descriptors: Cassia obtusifolia; Glycine max; Alternaria; Weed control; Biological control; Mycoherbicides; Phytoalexins; Biosynthesis; Inhibition; Glyphosate; Plant extracts Abstract: The major effort in developing pathogenic fungi into potential mycoherbicides is aimed at increasing fungal virulence to weeds without affecting crop selectivity. Specific suppression of biosynthesis of a phytoalexin derived from the shikimate pathway in Cassia obtusifolia L. by a sublethal dose (50 micromolar) of glyphosate increased susceptibility to the mycoherbicide Alternaria cassiae Jurair & Khan. Glyphosate applied with conidia suppressed phytoalexin synthesis beginning at 12 hours, but not an earlier period 8 to 10 hours after inoculation. The phytoalexin synthesis elicited by fungal inoculation was also suppressed by darkness. The magnitudes of virulence of the mycoherbicide in the dark or with glyphosate in the light were both higher than after inoculation in the light with the same concentration of conidia in the absence of glyphosate. Five times less inoculum was needed to cause disease symptoms when applied with glyphosate than without. Glyphosate did not render A. cassiae virulent on soybean (Glycine max), a crop related to the host. These results suggest that a specific inhibition of a weed's elicited defense response can be a safe way to enhance virulence and improve the efficacy of the mycoherbicide. 207 NAL Call.

In greenhouse experiments, greatest goosegrass control was achieved with diclofop when plants were maintained at 1.3 cm. Increased diclofop rates were required to suppress goosegrass mowed higher than 1.3 cm or unmowed. Greater than 90% goosegrass control was achieved with the combination of 1.3-cm mowing height and 0.6 kg ai ha-1 of diclofop. In field experiments, a minimum of 2 weeks was necessary for complete herbicidal activity. Diclofop at 1.1 kg ha-1 provided >90% control of goosegrass mowed between 1.9 to 2.5 cm. The addition of nonionic surfactant (0.25% by vol) to diclofop did not influence control. The addition of metribuzin (0.1 kg ai ha-1) to diclofop resulted in initial increased control, but it was transient. The addition of MSMA (2.2 kg ai ha-1) to diclofop reduced goosegrass control an average of 18% compared to diclofop treatments alone. Tifdwarf bermudagrass was more sensitive to diclofop compared to Tifgreen. Seven to 14 days were required for Tifdwarf to recover from initial injury. This injury, although significant, was acceptable for bermudagrass used for golf greens. Clipping weights following treatment were also less for Tifdwarf than Tifgreen. 209 NAL Call.

Includes references. Language: English Descriptors: Weed control; Plant pathogens; Mycoherbicides; Biological control; Herbicides; Synergism Abstract: Herbicides are used on crops and soils to control weeds in various crop production systems. They may also affect soil properties, plant pathogens and saprophytic microorganisms, as well as the host or non-target host plants. These effects normally have little influence on crop growth and generally prove beneficial. However, it has been shown that several herbicides can predispose crop plants to increased disease and as the use of herbicides on various crops increase it is important to evaluate the nature of herbicide-disease predisposing interaction. Procedures may then be taken to avoid or correct problems of detrimental interactions between herbicides and plant diseases. This paper explores the possibility of exploiting these interactions to improve weed control by mycoherbicide or mycoherbicide-herbicide combinations. 212 NAL Call.

Language: English Descriptors: U.S.A.; Montana; North Dakota; Euphorbia esula; Cecidomyiidae; Weed control; Biological control; Biological control agents Abstract: Spurgia esulae Gagne (= Bayeria capitigena Bremi of Solinas & Pecora), a multivoltine gall midge recorded on Euphorbia esula in Italy, was selected as a candidate for the biological control of leafy spurge (Euphorbia esula L. "complex") in North America. Its potential host range was studied in 1982 at Rome, Italy, and in 1984 at Albany, Calif., using populations associated with Euphorbia esula from San Rossore near Pisa, Italy. Of 56 plant species or varieties in 22 families tested at the Rome laboratory, the midge oviposited and completed its life cycle only on plants in the genus Euphorbia (subgenus Esula). In the tests conducted in Rome, complete development occurred on five populations of North American leafy spurge (Montana, Nebraska, North Dakota, Oregon, and Saskatchewan) and on European E. peplus L., E. cyparissias L., E. myrsinites L., E. characias L., E. serrulata Thuillier, and on E. lathyris L. from Chico and Castro Valley, Calif. Of 12 native North American Euphorbia species tested at Albany in 1984, four species in the subgenus Esula (E. incisa Engelmann, E. palmeri Engelmann, E. robusta (Engelmann) Small, and E. spathulata De Lamarck) supported the complete development of S. esulae. The restricted host range suggested use of this midge as a biological control agent against leafy spurge in North America. Releases of S. esulae were made in Montana in 1985 and in North Dakota in 1986; this species became established in both states. 227 NAL Call.

Language: English Descriptors: Greece; Centaurea solstitialis; Tephritidae; Curculionidae; Feeding behavior; Weed control; Biological control agents Abstract: More than 15 species of capitulum-feeding insects colonized a randomized garden plot of yellow starthistle, globe artichoke, cultivated safflower, and Cirsium creticum (Lam.) D'Urv. in northern Greece in 1985. Among these insects were seven potential biocontrol agents of yellow starthistle: the cynipid wasp, Isocolus sp.; the tephritid flies, Chaetorellia australis Hering, Terellia uncinata White, and Urophora sirunaseva (Hering); and the curculionid beetles, Bangasternus orientalis (Capiomont), Eustenopus villosus (Boheman), and Larinus curtus (Hochhuth). These potential agents only attacked yellow starthistle plants, which were grown from seed collected in Greece and the United States. This host specificity data was used to justify the subsequent release of C. australis and E. villosus in the United States. The relative intensity of interspecific interactions among capitulum-feeding insects of yellow starthistle is discussed, as well as the potential effectiveness of E. villosus as a biocontrol agent. This study points to the usefulness of the open field test in host specificity determination of insects for biological control of weeds. 229 NAL Call. No.: aS21.A8U5/ARS Hydrilla. Buckingham, G.R.

Language: English Descriptors: California; Centaurea solstitialis; Curculionidae; Weed control; Biological control; Oviposition; Altitude Abstract: The efficacy of Bangasternus orientalis Capiomont against its host Centaurea solstitialis L. was determined at two different sites (low and high elevation) in California over a 2-yr period. Host plant and weevil phenology were delayed at the high elevation site. Consequently, the initiation of secondary flower buds (high elevation site) was extended well into November, long after the ovipositing adult weevil population had expired. More than 50% of the egg- bearing test heads did not become infested with mature pupae because of larval mortality. After seed reduction by the weevil, 70% of the seeds remained in the test heads. Our data suggest that B. orientalis appears to be ineffective by itself as a biological control agent of yellow starthistle in California. 233 NAL Call.

Journal of nematology v. 24 (1): p. 199-204; 1992 Mar. Includes references. Language: English Descriptors: Acroptilon repens; Subanguina; Weed control; Biological control agents Abstract: The knapweed nematode Subanguina picridis is a foliar parasite that is of interest as a biological weed control agent of Russian knapweed. Attempts were made to culture the nematode in callus, excised roots and in shoots derived from roots of Russian knapweed. In callus tissues, the nematode developed from second-stage juvenile to adult but failed to reproduce; it developed only to the fourth stage in excised roots. However, S. picridis was successfully cultured in vitro in shoots derived from roots. The nematode induced galls on the leaves, petioles, and shoot apices and developed and reproduced inside the galls. Gibberellic acid increased the development rate of the nematode and promoted the formation of males. This is the first gnotobiotic culture of a nematode used for biological weed control. 235 NAL Call.

Language: English Descriptors: Cirsium arvense; Weed control; Biological control; Puccinia; Infection; Systemic diseases; Fungal spores; Spore germination; Stimulation; Temperature; Buds; Dormancy Abstract: Systemic aecial infections of secondary Canada thistle shoots were observed 4-6 weeks after inoculation of root cuttings with teliospores of Puccinia punctiformis. Pretreatment with a stimulatory thistle root extract sometimes increased infection. Inoculation of dormant buds was the most effective way to induce infection of root cuttings. Aqueous soil extracts from potted Canada thistle plants stimulated teliospore germination. The active component in the soil was soluble in hexane, volatile, and was similar in nature to the hexane extract of steam-distilled Canada thistle roots. Optimum temperature range for stimulated teliospore germination on 1% agar was 16-20 C at 7 days. 238 NAL Call. No.: QH301.A76 Industry's perception of bioherbicides. Wilson, S.

Language: English Descriptors: California; Silybum marianum; Septoria; Biological control; Infection; Environmental factors; Weed control; Relative humidity; Light relations; Moisture; Air temperature; Inoculum; Spore germination Abstract: Septoria silybi infected milk thistle (Silybum marianum) frequently when daylight was provided during high humidity inoculation periods but rarely when light was excluded, because of the pathogen's requirement for open stomata to penetrate thistle leaves. When stomata were artificially closed with abscissic acid, S. silybi failed to penetrate even during daylight. Conversely, the application of fusicoccin opened stomata on thistle leaves kept in the dark and permitted penetration. Hyphae of S. silybi encountered stomata as frequently on milk thistle leaves held in the dark as on those exposed to daylight. Hydrotropism, the directed growth of germ tubes and branches toward stomata, was not exhibited by S. silybi. Superficial hyphae reached or crossed stomatal pores with similar frequency, irrespective of whether humidity gradients might have existed at such sites or not. S. silybi infected milk thistle after periodic (8 hr/day for 6 days) or prolonged (continuously for 2.5 days) postinoculation dyring. The amount of disease occurring on plants exposed to periodic drying was comparable to those incubated continuously at high humidity. Severity of disease resulting from inoculation with a given number of spores of S. silybi increased proportionally with leaf age. Whereas S. silybi infected young and old leaves of milk thistle with similar efficiency, the rate of lesion expansion was 2.5 times higher on old leaves than on young leaves. 240 NAL Call.

Conidia produced in 10:1 medium were longer and thinner than conidia from 30:1 and 80:1 media, and a higher proportion contained two, rather than one, nuclei per conidium. After either 6 or 12 h on cellophane membranes, a greater proportion of conidia produced in the 10:1 medium had germinated compared with conidia from 30:1 and 80:1 media. Germination on attached leaves of Sesbania exaltata was greatest with conidia from 10:1 medium when assayed after either 6 or 24 h. Equality of variance tests implied that the leaf environment had a greater influence on the germination of conidia from 30:1 medium than conidia from 80:1 or 10:1 media. All conidial treatments caused losses in biomass of seedlings of S. exaltata. Conidia produced in 10:1 or 30:1 media induced greater reduction in shoot height, and conidia from 10:1 medium induced greater reduction in shoot dry weight than did conidia from 80:1 medium.

Brush control using fire, chemicals, and mechanical methods has been tested previously; but limited information is available on goats. This study evaluated the effect of 4 goat- stocking levels in a short duration grazing system and mechanical brush crushing on chaparral shrubs, herbaceous vegetation, litter, and soils. After 4-1/2 years, percent total shrub cover was lower (P<0.05) on paddocks stocked at 1.4, 2.4, and 4.2 Spanish goats/ha (35, 39, and 38%, respectively) compared to unstocked controls (51%). Crushing brush increased the effectiveness of goats; mean total shrub cover was lower (P<0.05) on paddocks where brush was crushed vs not crushed (33 and 50%, respectively). Shrubs least preferred by goats were not affected, while preferred browse was impacted at all stocking levels. Goat stocking and brush treatments did not affect perennial herbs, while annuals were generally increased by soil disturbance. Less litter (P<0.05) accumulated under shrubs subjected to heavy stocking levels compared to unbrowsed paddocks. Concentrations of N and P in the soil were also affected (P<0.05) under desert ceanothus (Ceanothus greggii Gray) where the soil bulk density was also increased (P<0.05). While goats can reduce total shrub cover, problems may result. Perennial herbaceous vegetation did not respond. Shrubs preferred by goats were also preferred by native deer. Reduced forage diversity and nutritional stress could result if these species were eliminated from the stand. Also, trampling disturbance by goats affected nitrogen accumulation in the litter and soil, but more importantly heavy browsing may eliminate nitrogen-fixing shrubs. 247 NAL Call.

A high percentage of these species are in the orders Coleoptera, Lepidoptera, and Diptera and are monophagous endophages associated with the capitulum. The guilds associated with yellow starthistle in southern Europe consist of capitulum-infesting species; endophages in the stems, rosette foliage, and roots; and ectophages on leaves and stems. At least five monophagous species that attack the capitulum in different ways could potentially be used in a biological control program in the United States. 249 NAL Call.

The phytophagous arthropods collected from these plants belonged to 27 families in six orders. Coleoptera accounted for 48%, Hemiptera 27%, Lepidoptera 16%, Diptera 5%, Hymenoptera 2%, and Acarina 2%. Fifty-eight percent reproduced on S. acuta or S. rhombifolia or both. Twelve species were considered to have potential as biological control agents for these weeds. One, Calligrapha pantherina Stal, has been released in Australia and is causing extensive defoliation of S. acuta. Prospects for biological control of these weeds are favorable. 290 NAL Call.

Language: English Descriptors: Zea mays; Sorghum halepense; Weed control; Biological control; Biological control organisms; Cochliobolus; Pathogenicity; Virulence; Formulations; Inoculum; Growth stages; Plant density; Phytotoxicity Abstract: Bipolaris sorghicola (isolate BS1) and an unidentified Bipolaris species (isolate BX1) were isolated from johnsongrass in North Carolina. Inoculum of BX1 was mass produced in solid and liquid cultures, whereas inoculum of BS1 could only be produced in solid cultures. When six formulations of inoculum of BX1 were compared, vegetable oil was the best adjuvant. Isolate BX1 displayed some host specificity in pathogenicity tests. In the greenhouse, isolate BS1 was more virulent on johnsongrass than isolate BX1. In growth chambers, increasing conidium concentration and younger plant ages interacted to increase virulence of BX1, as did interactions between inoculation, johnsongrass density, and low soil fertility. In Raleigh, NC, isolate BX1 caused very little damage in the field, with or without pretreatment with metolachlor. In Greenville, MS, isolate BX1 caused significant (52%) mortality to annual johnsongrass with very little damage to corn or grain sorghum. The biocontrol potential of the two organisms is uncertain. 305 NAL Call. No.: QD1.A45 Pathogens with potential for weed control. Charudattan, R. Washington, D.C. : The Society; 1990.

Includes references. Language: English Descriptors: Plant pathogens; Weed control; Biological control; Mycoherbicides Abstract: Biological control with plant pathogens is an effective, safe, selective, and practical means of weed management that has gained considerable importance. The recent success in using certain rust and smut fungi as classical biocontrol agents, the registration and commercial use of two facultatively parasitic fungi as mycoherbicides in the United States, and the potential registration of two more mycoherbicides in the USA and Canada have further stimulated worldwide interest in biological weed control with plant pathogens. Approximately 45 species of fungi are reported to be under evaluation or development in 19 countries and 44 locations against about 65 weeds. Included are 14 of the top 18 world's worst weeds, and several others of regional and specific importance. Among pathogens with potential, several species have been found that attack more than one weed species. Efforts should be made to develop these pathogens as broad-spectrum mycoherbicides through strain selection or genetic engineering. Certain weed-pathogen systems have been shown to be suitable for low-input weed control technology that could be developed with public support and dispensed through user's efforts. Many others may be suitable for specialty or niche markets in which the target weed lacks suitable chemical or other means of control. It is anticipated that public institutions and private industries will continue to support research and development, respectively, of classical and mycoherbicidal candidates and thus promote this field of alternative weed control methods. 306 NAL Call.

Language: English Descriptors: Australia; Mimosa; Insects; Weed control; Biological control Abstract: Phytophagous insects in five orders, 50 families, 101 genera, and 114 species constitute the insect fauna of Mimosa pigra L., a weed introduced into northern Australia from tropical America. Most insect species attacking M. pigra in Australia were rarely or only occasionally encountered, are native or naturalized, polyphagous, and feed externally on the woody stems and mature foliage. Seventy-one species (62.3%) were known to breed on the plant, but only 13 (11.4%) were endophagous. No species were endophagous on flowers, fruit, seeds, or leaves. Thirty species (26.3%) are known pests of cultivated plants. Insects introduced into Australia for the biological control of M. pigra will find largely unexploited food sources, especially on new growth or inside the reproductive structures. 309 NAL Call.

Language: English Descriptors: Texas; Eichhornia crassipes; Neochetina eichhorniae; Population dynamics; Aquatic weeds; Weed control; Biological control agents Abstract: Population dynamics of waterhyacinth, Eichhornia crassipes ((Martinus) Solms-Laubach), and a biological control agent, the weevil Neochetina eichhorniae (Warner), were quantified at a site in Wallisville, Tex., during 1987 and 1988. A decline of waterhyacinth occurred that was most pronounced during the 1988 growing season. Changes included decreases in (1) living above water biomass/m2 (approximately -57%), (2) living below water biomass/m2 (approximately-39%), (3) number of living leaves/plant (approximately-50%), and (4) weight/plant (-40%). Associated with these decreases was a 1.5-fold increase in plant density. The waterhyacinth was severely damaged by N. eichhorniae. Highest numbers of N. eichhorniae adults (>55 weevils/m2) occurred in samples collected 15 September 1987. Decreases in the number of weevils for both sexes followed. Declines approached 8 weevils/m2 per month for the following 5 mo. Numbers of pupae per square meter decreased during 1987 by 7.3 pupae/m2 per month. Larval density increased during the winter months with highest larval density noted during December and January. This peak was followed by decreases in third instars of approximately 80%. Increases in the number of adults and third instars occurred during the 1988 growing season, however, pupal density remained low (near 0) thereafter. Environmental factors that contributed to the waterhyacinth declines included a drought, nutrient conditions, intermittent freezing temperatures, as well as sustained N. eichhorniae herbivory. 311 NAL Call.

Language: English Descriptors: Idaho; Hypericum perforatum; Chrysolina; Agrilus; Weed control; Biological control; Biological control agents; Population dynamics; Seasonality; Phenology Abstract: Although considerable study of Chusolina quadrigemina (Suffrian) and C. hyperici (Forster) has occurred in California, Australia, and Canada, these species have not been thoroughly studied in Idaho or the Pacific Northwest. Northern Idaho populations of the two leaf beetles were sampled periodically from four (three grassland and one forest meadow) sites infested with St. Johnswort during 1985 and 1986. The egg was the dominant overwintering stage at most sites and most larval feeding took place in the spring and early summer. Beetle population levels and trends varied from site to site. C. quadrigemina was the dominant species in the grassland sites; C. hyperici dominated in the forested site. The bronze color morph of C. quadrigemina dominated over the other color morphs at all sites where it was present. Populations of Agrilus hyperici (Creutzer) (Coleoptera: Buprestidae) also were sampled periodically from the same four St. Johnswort infestations during 1985 and 1986. Adults emerged during late May through July. Eggs were laid during July. The proportion of stems infested with eggs at the four sites ranged from 0 to 92%. However, mean larval numbers were always less than one per plant. Live and dead plants contained live larvae. Nearly one-half of the dead plants at one site had once been infested. Based on the larval infestation levels observed (live larvae and adult exit holes), particularly in dead plants, it appears that A. hyperici has contributed significantly to St. Johnswort suppression in Idaho. Annual grasses (i.e., Bromus spp.) and weedy forbs (i.e., Centaurea spp.) constitute the major replacement vegetation at most of the St. Johnswort infested study sites in northern Idaho. 313 NAL Call.

Language: English Descriptors: South Africa; Sesbania punicea; Apionidae; Biological control agents; Weed control Abstract: Sesbania punicea (Cav.) Benth. is a perennial legume that has become a weed of major importance in South Africa. Until recently, S. punicea was colonized by only one insect herbivore of any consequence, an introduced apionid weevil species, Trichapion lativentre (Beguin-Billecocq). The vegetative growth and reproductive capacity of S. punicea was shown to be significantly lower on plants at sites colonized by T. lativentre than on plants at sites without the weevils. However, these initial comparisons did not account for the extraneous effects of intersite differences, and additional analyses have been undertaken to determine the actual effects of the weevils on the weed. Regression models showed that between 77 and 83% of the variance in vegetative growth (leaflets, rachides, and stems) of S. punicea was explained by the presence of weevils, by their history of colonization, and to a lesser extent, by the density of the weevils, expressed as cumulative weevil-days. Kruskal-Wallis tests showed that the weevils also almost completely nullified the reproductive capacity of the plants by destroying nearly all of the flower buds. The results confirm that the suppression of plant growth was attributable, almost entirely, to weevil herbivory and that, in moderate to dense infestations of the weed, T. lativentre is equally effective as a biological control agent, regardless of site characteristics such as the spacing, height, or size of the trees. 334 NAL Call.

Language: English Descriptors: Oregon; Washington; Hordeum vulgare; Secale cereale; Triticum aestivum; Bromus tectorum; Biological control; Field experimentation; Growth inhibitors; Pseudomonas; Screening; Weed control; Yield increases Abstract: Rhizobacteria have the potential to suppress plant growth. We evaluated the effect of native pseudomonads on downy brome (Bromus tectorum L.), a troublesome weed in small- grain-producing lands. Pseudomonas spp. were isolated from winter wheat (Triticum aestivum L.) and downy brome roots and tested to determine their potential as biological control agents for this weed. Pseudomonads were screened in agar and soil for inhibition of downy brome root growth and lack of inhibition of winter wheat root growth. Of more than 1000 isolates tested, 81 inhibited downy brome and not winter wheat in the agar seedling bioassay. Six isolates consistently inhibited downy brome growth and not winter wheat in soil contained in pots in the growth chamber. In nursery field trials in which downy brome was planted in rows and adequately fertilized, some of the bacterial isolates reduced downy brome populations up to 30% and shoot dry weight up to 42%. Field studies were also conducted at three sites in eastern Washington in which brome-inhibitory bacteria were applied to wheat fields infested with natural populations of downy brome. Of the three isolates studied in the field, two reduced plant populations and aboveground growth of downy brome up to 31 and 53%, respectively, compared with noninoculated controls. At two of the three locations, winter wheat yields were increased 18 to 35% because of the suppression of downy brome growth. Brome-suppressive bacteria isolated from the rhizoplane of winter wheat and downy brome can be used as biological control agents for downy brome. 340 NAL Call.

Includes references. Language: English Descriptors: Weed control; Biological control; Soil fungi; Gliocladium virens; Host range; Mycoherbicides Abstract: Current methods of biological weed control with plant pathogens rely mainly upon foliar application of host- specific pathogens which infect an established weed population. This contrasts with chemical weed control where application can provide broad-spectrum preplanting, pre- emergence or post-emergence control of potential weed populations. This limitation to the value of mycoherbicides, relative to chemical herbicides, could be overcome with the finding that the saprophytic, soilborne fungus Gliocladium virens Miller, Giddens & Foster can provide the needed broad- spectrum pre-emergence control of weeds. Application of G. virens, cultured on peat moss amended with sucrose and ammonium nitrate, reduced a broad range of weeds by at least 90 percent. Those seedlings which did emerge were severely stunted. Herbicidal activity was correlated with production of the steroidal phytotoxin viridiol. Viridiol caused a severe necrosis of roots but did not affect other tissues. Crop toxicity was avoided by directed application of the mycoherbicide above the root zone of crop seedlings. The use of G. virens and other soilborne fungi for weed control is discussed. 356 NAL Call. No.: 99.8 F7623 Some future directions for biologically based vegetation control in forestry research.

Language: English Descriptors: Vegetation management; Weed control; Biological control; Phytotoxins; Allelopathy; Microbial pesticides; Research Abstract: During the past decade, considerable research efforts have been devoted towards non-chemical weed control. Some of these efforts have been directed towards the control of forest weed species. Non-chemical control of forest vegetation encompasses many approaches and techniques and only a few of them are discussed in this paper. Three major and promising research areas are identified: 1) allelopathy, (2) microbially produced phytotoxins, and 3) bio-control. Each of these weed management strategies is briefly presented and discussed using examples from the forestry literature. 357 NAL Call.

Language: English Descriptors: Glomerella cingulata; Biological control organisms; Weed control; Culture media; Liquids; Spores; Mycelium; Biomass accumulation; Jussiaea; Aeschynomene virginica; Clidemia hirta Abstract: The effect of V8 juice concentration (5 to 40%, vol/vol), spore inoculum density (10(5) and 10(7) spores per ml), and liquid batch or fed-batch culture condition on mycelium and spore production by Colletotrichum gloeosporioides was evaluated. The amount of mycelium produced, the time required for initiation of sporulation following attainment of maximum mycelium, and the time for attainment of maximum spore concentration increased with increasing V8 juice concentration in batch culture. Cultures containing V8 juice at > 10% achieved a similar spore density (apparent spore-carrying capacity) of about 0.8 mg of spores per ml (1 x 10(7) to 2 x 10(7) spores per ml) independent of inoculum density and V8 juice concentration. The relative spore yield decreased from a high of 64% of the total biomass for the low-inoculum 5% V8, culture, through 13% for the analogous 40% V8 culture, to a low of 2% for the high-inoculum 27% V8 culture. Fed-batch cultures were used to establish conditions of high spore density and low substrate availability but high substrate flux. The rate of addition of V8 juice was adjusted to approximate the rate of substrate utilization by the (increasing) biomass. The final spore concentration was about four times higher (3.0 mg of spores per ml) than the apparent spore-carrying capacity in batch culture. This high spore yield was obtained at the expense of greatly reduced mycelium, resulting in a high relative spore yield (62% of the total biomass). Microcycle conidiation occurred in the fed-batch but not batch systems. These data indicate that substrate-limited, fed-batch culture can be used to increase the amount and efficiency of spore production by C. gloeosporioides by maintaining microcycle conidiation conditions favoring allocation of nutrients to spore rather than mycelium production. 360 NAL Call.

Significant negative correlations were obtained between the relative virulence of the isolates and the dry weights of dandelion plants inoculated in a controlled environment; and positive correlations were detected between the relative virulence of isolates and reduction in number of dandelion plants in turfgrass swards infested with inoculum of the isolates. In August 1988, an 80.7% reduction in the number of dandelion plants was detected in a turfgrass sward treated in 1987 with four applications of heat-killed seed of perennial ryegrass (100 g m-2 application-1) infested with isolate R30 of S. sclerotiorum, followed by six applications at the same rate in 1988. Populations of dandelions in untreated swards increased by 22.2% during the same period. Heat- killed seed of perennial ryegrass (100 g m-2) infested with isolate R30 applied simultaneously with dandelion seed (25 g m-2) onto a sward of Kentucky bluegrass reduced the establishment of dandelion seedlings by 85.5%. Necrosis or discoloration did not develop on Kentucky bluegrass, creeping bentgrass, annual bluegrass, or quackgrass treated with inoculum of Sclerotinia. Sclerotia of Sclerotinia spp. were found, on occasion, in crowns but not on the foliage of diseased dandelions. 397 NAL Call.

Language: English Descriptors: Cirsium arvense; Puccinia; Volatile compounds; Sexual reproduction; Biological control; Aroma; Chemical analysis Abstract: Fragrance volatiles responsible for the sweet aroma produced when Canada thistle [Cirsium arvense (L.) Scop.] plants are infected with the systemic sexual stage of the Canada thistle rust [Puccinia punctiformis (Strauss) Roehl.], a prospective biological control agent for that weed, have been identified by capillary gas chromatography/mass spectrometry (GC/MS) after thermal desorption from Tenax. The four major peaks in the chromatogram were identified as benzaldehyde, phenylacetaldehyde, phenethyl alcohol, and indole, at average relative molar concentrations of 0.05, 0.85, 0.44, and 1.00, respectively. The known insect- attracting properties of these compounds may aid cross- fertilization of the fungus. Healthy Canada thistle flowers emitted these same compounds, except indole, plus methyl salicylate. Phenylacetaldehyde was the most concentrated fragrance volatile of the flowers. 398 NAL Call.

In the series analytic: Microbes and Microbial Products as Herbicides / edited by R.E. Hoagland. Literature review. Includes references. Language: English Descriptors: Weed control; Biological control; Plant pathogens Abstract: An increasing emphasis on biological alternatives to chemicals for pest control is expected because of the persistent lack of confidence in synthetic chemical pesticides by a discerning society. Chemical residue contaminations of food, water, soil and the environment from use or misuse of pesticides are undeniably strong emotive issues that lead to an even more stringent regulatory climate and consequently to cost increases for chemical pesticide development. The trend toward biologicals is further strengthened by rapid development of pest resistance to the safer, metabolically specific chemical pesticides. The shift from chemical based to biologically based pest control technology will require substantially more public and private sector input into target and agent biology at the ecosystem, organismal and molecular levels than is now committed, and significant re-direction of genetic engineering research efforts to strain improvement of potential biological pesticides is required. 405 NAL Call.
