 Quick Bibliography SeriesBibliographies in the Quick Bibliography Series of the National
 Agricultural Library, are intended primarily for
 current awareness, and as the title of the series implies, are not
 indepth exhaustive bibliographies on any given subject.  However,
 the citations are a substantial resource for recent investigations
 on a given topic.  They also serve the purpose of bringing the
 literature of agriculture to the interested user who, in many
 cases, could not access it by any other
 means.  The bibliographies are derived from computerized on-line
 searches of the AGRICOLA data base.  Timeliness of topic and
 evidence of extensive interest are the selection criteria.
 
 The author/searcher determines the purpose, length, and search
 strategy of the Quick Bibliography.  Information regarding
 these is available upon request from the author/searcher.
 
 Copies of this bibliography may be made or used for
 distribution without prior approval.  The inclusion or
 omission of a particular publication or citation may not be
 construed as endorsement or disapproval.

 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.

 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.

 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.

 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.

 Abstract:  The use of plant pathogens as biocontrol agents of
 aquatic plants has only just begun to be considered as a major area
 of research in the United States. 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.

 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.

 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.

 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.

 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.

 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.

 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.

 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.

 Abstract:  Integrated pest management (IPM) initially focused on
 insect pest control. More recently, IPM encompasses a
 broader concept of management, one which crosses several
 disciplinary boundaries. This article reports results of
 research dealing with four integrated management decisions for
 alfalfa (cultivar selection, insect control, weed control, and end-
 of-season harvest options).

 Abstract:  A linear programming model was used to determine which
 crop rotations and weed management systems result in the highest
 net farm income for each of three farm sizes (120,
 240, and 480 hectares) under alternative tillage systems. 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.

 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.

 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.

 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.

 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.

 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.

 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.

 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.

 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.

 Abstract:  This companion volume to the IPM Scout Manual is a guide
 to the decision-making process involved in managing
 insect, nematode, and vertebrate and weeds. Since a
 multiplicity of factors affects the crop damage or potential for
 damage, each management decision requires a separate
 analysis not a prescribed solution. The growth stages of corn,
 soybeans, alfalfa, small grains, and grain sorghum and the
 life cycles of their pests are reviewed. Equipment calibration
 methods, soil test evaluations and fertilizer recommendations, and
 sampling methods are provided.

 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.

 Abstract:  Johnsongrass seedlings were inoculated with conidia of
 four fungi, Exserohilum turcicum (Et), Colletotrichum
 graminicola (Cg), Gloeocercospora sorghi (Gs), and/or
 Bipolaris halepense (Bh). 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.

 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.

 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.

 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.

 Abstract:  Greenhouse and field experiments were performed to
 investigate diclofop rate and mowing height interactions on
 goosegrass control and 'Tifgreen' and 'Tifdwarf' bermudagrass
 tolerance. 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.

 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.

 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.

 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.

 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.

 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.

 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.

 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.

 Abstract:  Conidia of Colletotrichum truncatum (NRRL 13737) were
 produced in semidefined, liquid media, with total carbon
 concentrations of 4 g/L and carbon/nitrogen ratios of 80:1, 30:1,

 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. Further research on increasing the
 efficacy of mycoherbicide conidia by modifying the
 phyllosphere environment and the nutritional conditions of the
 conidiation medium is needed.

 Abstract:  The key to managing Arizona chaparral depends on
 creating and maintaining brush-free or savanna-like habitats. 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.

 Abstract:  Field surveys and published data revealed that at least
 42 species of insects use yellow starthistle as a
 breeding host in southern Europe. Twelve of these species are newly
 reported to feed on the plant. 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

 Abstract:  Insect, weed and disease management recommendations for
 turfgrass are presented in ready reference charts for the
 commercial pesticide applicator. Charts contain information
 enabling the applicator to identify many insects, weeds and
 diseases that attack turfgrass and match them with the
 suggested cultural and biological control practices and
 chemical control agents and their recommended dosages.
 Pesticide tolerance charts and herbicide charts link pesticide
 trade names to their common names.

 Abstract:  The natural enemies of Sida acuta and S.
 rhombifolia in Mexico were surveyed over a period of 3 yr. 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.

 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.

 Descriptors: Plant pathogens; Weed control; Biological

 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.

 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.

 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.

 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.

 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.

 Abstract:  The South American weevil Neohydronomus affinis
 Hustache was first released in North American as a biological
 control of waterlettuce, Pistia stratiotes L., at Kreamer
 Island, Lake Okeechobee, Fla., on 29 April 1987. Releases were made
 at six additional sites on southern Florida. Periodic
 observations at several of these sites indicate the weevils have
 become established and are dispersing. At some sites,
 weevil-infested plants are exhibiting symptomology typical of
 plants in other countries where N. affinis has been used
 successfully to control this aquatic weed.

 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.

 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.

 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.

 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.

 Abstract:  Sixty isolates of the plant pathogenic fungus
 Sclerotinia sclerotiorum (Lib.) de Bary and six isolates of
 Sclerotinia minor Jagger were evaluated in a controlled
 environment for virulence on leaves excised from 8-week-old
 dandelion plants. 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.

 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.

 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.
