About 1,500 Colorado farmers are getting daily reports on irrigation needs and pest problems "beamed up" via satellite by two commercial firms. ARS and Colorado State University scientists worked out the cataloging and analysis of data for this computer system. Irrigation reports are based on a statewide, 25-station meteorological network, administered by the scientists. All day, the network collects and processes weather data. At night, computers deliver the information to scientists who compile it and forward the complete package to the two companies. In the morning, Colorado farmers can find out precisely how much water their crops will need that day. They also get early alerts and advice on identifying and tracking insect and disease infestations across the state.

Microorganisms discovered by ARS scientists are key ingredients in two new commercial products registered by the Environmental Protection Agency as the first postharvest biofungicides. Cooperative Research and Development agreements (CRADAs) between ARS and two companies resulted in these natural components being used to control rot in stored fruit. ECOGEN of Langhorne, PA, made ASPIRE from the yeast Candida oleophila, found on tomatoes. Patented by ARS and Israeli scientists, the yeast combats postharvest rot on citrus and apples. EcoScience of Worcester, MA, developed BIO-SAVE 11 from Pseudomonas syringae, a bacterium that fights rot on apples, pears and citrus. This organism was isolated from the surface of apples and is being patented by ARS. California's Environmental Protection Agency concurrently registered BIO-SAVE 11 as a biofungicide. The current worldwide market postharvest treatments is about $18 million a year for citrus and $8 million for apples. (PATENT 5,425,941--yeast; PATENT APPLICATION 07/618,437--bacterium)

A new tomato just reaching some New York grocery stores is the first to carry a gene with an ARS pedigree. A license agreement with ARS permits DNA Plant Technology Corp., Oakland, CA, to use the gene to prolong freshness and flavor of more than a dozen fresh fruits and vegetables. DNAP biotechnologists designed the new Endless Summer tomato. Earlier, ARS and University of California at Berkeley researchers found a key gene in zucchini and tomato and retooled it to keep production of a natural plant hormone, ethylene, turned off. Ethylene occurs naturally in tomato and many other plants. In nature, once ethylene is turned on, it stays on, causing fruit to ripen, but then overripen and rot. Most commercial tomatoes are picked before ripening is completed. This shortens the time the fruit can stay on the vine to naturally develop sugars and acids crucial to hearty flavor. Tomatoes with the rebuilt gene can stay on the vine longer to enhance flavor. Later, when exposed to ethylene in the warehouse, they soften and turn red. Endless Summer tomatoes are now being grown in Florida and test-marketed in New York. DNAP expects to sell them throughout the country by 1997. (PATENT APPLICATION 07/579,896)

Patent Licenses
...To Prepeeled Fruit, Inc., of Groveland, FL, to use ARS patented technology to prepeel citrus with commercially available food-grade enzymes. That eliminates hand peeling and allows more precise control of portions. Also, the process removes the bitter white portion of grapefruit peel. Prepeeled fruit is ideal for school lunch programs and restaurants. Prepeeled Fruit incorporated the technique in a new processing plant it built in a small rural town in central Florida. Recently opened with local personnel, the plant can process about 50,000 pounds--about 100,000 pieces--of fresh fruit each eight-hour shift. When fully operational, the plant expects to hire about 100 people. (PATENT 4,284,651)

...To Neogen Corp., Lansing, MI, to develop a commercial kit that detects a medication called salinomycin in food and poultry feeds. Salinomycin is added to broiler chickens' feed to prevent coccidiosis, a disease that costs U.S. poultry producers an estimated $450 million annually in medication and production losses. The kit will use monoclonal antibodies--the same basic principle as home pregnancy tests--to check whether any salinomycin residues linger in tissues of slaughtered chickens and whether salinomycin has been properly mixed into feeds. Salinomycin is not a synthetic chemical, but is prepared from fermentations of natural microorganisms. (PATENT APPLICATION 08/081,591)

...With Defense Research Technologies, Inc. of Rockville, MD, to improve a system for determining the number of insects in a grain sample by detecting the insects' feeding sounds. Called ALFID (Acoustic Location Fixing Insect Detector), the ARS-developed system captures and analyzes the sounds insects make as they feed on the grain. But the sensors often only detect the loudest sounds--meaning smaller insects could be missed. Scientists want to incorporate the company's technology that uses compressed air to amplify sound waves from even the smallest insects. ALFID could then do a better job of picking up fainter insect feeding sounds, especially from small larvae living inside grain kernels.

...With the Soil and Water Conservation Society, Ankeny, IA, to market a computer program, known as RUSLERevised Universal Soil Loss Equation. RUSLE increases the accuracy of predicting soil erosion by water, based on computer analysis. ARS scientists developed the original version in the 1960s to estimate soil erosion by water and to protect farms and rangelands against soil loss. ARS scientists will continue to refine the basic mathematical relationships and expand the database for the equation. SWCS will educate and train farmers, ranchers, land-use managers and agency personnel to help one million land users comply with the soil conservation provisions of the 1995 Farm Bill. SWCS also is continuing to distribute the latest input data developed by ARS and USDA's National Resources Conservation Service. RUSLE is being used to develop conservation compliance plans to reduce soil erosion on more than 34 million acres of farmland that will come back into production as Conservation Reserve Program contracts expire this year.

...With Cargill, Inc., Minneapolis, MN, to develop a newly isolated microorganism that could help protect silage from spoiling when the silo is opened to remove the silage for feeding dairy cows. Farmers already inoculate silage with microorganisms to speed fermentation. But inoculants now on the market don't protect against damaging yeast and fungal growth when silage is exposed to air. ARS and industry scientists isolated a strain of Lactobacillus buchneri from alfalfa silage. This organism produces compounds that inhibit yeast and mold growth in corn silage. An L. bucherni-based inoculant could reach the market within two years and cost about the same to manufacture as current silage inoculants.

...With Summit Plant Laboratories, Inc., of Fort Collins, CO, to develop a way to commercially produce sugarbeet clones. Clones--genetically identical plants--would advance breeding of commercial hybrids that resist disease or need less fertilizer. No sugarbeet clones are commercially available. And since this plant doesn't self-pollinate, it's difficult to obtain the large numbers of genetically similar plants needed for research and breeding. Clones would give plant breeders and researchers a reliable standard for comparison, year after year, to help further the competitiveness of the domestic sugarbeet industry. Private as well as public plant breeders would have access to the clones.

...With Valmont Industries, Inc., of Valmont, NE, to develop a way to automate the delivery of irrigation water based on plant temperature. Such a precision farming system might pay for itself in water savings. ARS-developed prototypes are being tested in California, Mississippi and Texas. One example is the use of flashlight-sized, infrared thermometers, mounted on an irrigation system that circles a field. Leaf temperatures are read every six seconds around the clock. Red lights on the irrigation system and at a computer console flash when the plant needs water to cool down. This temperature-time threshold is based on the discovery by ARS scientists that each crop has its own preferred temperature range at which it grows best. If this prototype were automated, farmers would insert a different computer cartridge into the computer for each crop they're watering. Then, the computer would decide when to water.

...With Pharmacognetics, Inc., of Bethesda, MD, to investigate natural compounds from microorganisms and plants of Latin American rain forests as potential new environmentally friendly products. Biopesticides, pharmaceuticals and other products could emerge from the research. ARS scientists will examine extracts from the microorganisms and plants to see if they contain biologically active compounds. If so, they will isolate and identify the active chemicals. For chemicals having biopesticidal properties, the ARS scientists will focus on those that, in tiny doses, attack specific pests. They will evaluate whether plants that make useful compounds could become new, high-value crops for U.S. farmers. They also will assess potential for mass-producing helpful microorganisms, through fermentation on surplus farm crops or on agricultural wastes such as peanut shells. Collectors of the plants and microorganisms will be mainly botanists and ethnobotanists based in South America. They will supply materials having known traditional uses in farming or medicine. Pharmacognetics plans to share profits resulting from the materials with the countries that are the sources.

...With the Electric Power Research Institute and the U.S. Geological Survey, to develop a global warming computer model. It will predict effects of climate change on water availability for electricity and other uses such as drinking, irrigation and recreation. New techniques will be developed and incorporated in a USGS modular "shell" along with various existing computer models. The components, such as those for irrigation and hydroelectric power scheduling, can be easily plugged in or removed from the shell. In the project's first phase, scientists will incorporate the ARS Snowmelt Runoff Model, which forecasts the amount of snowmelt runoff each spring. Once this is done, the Electric Power Research Institute can generate climate-change scenarios for power companies in snow regions. The snowmelt model's simplicity eliminates the need to calibrate long-term weather records. ARS also has labs in Arizona and Idaho working with USGS to incorporate the snowmelt and other models. The final product will use projected changes in precipitation and temperature to predict effects on soil moisture and groundwater as well as snowmelt runoff.

...With Gustafson, Inc., of Plano, TX, to develop strains of a fungus that farmers can use to prevent aflatoxin from infesting peanuts. Certain strains of Aspergillus fungus produce aflatoxin, which--in a bad year--has cost peanut growers millions in losses. ARS scientists discovered and patented Aspergillus strains that do not produce aflatoxin. They found that spreading the harmless fungus in the soil crowds out the aflatoxin-producing strains--serving as a biological control against contamination. Gustafson and ARS will cooperate in field tests to develop ways to mass-produce and deliver the harmless fungi as a commercial product peanut growers can use. (PATENT 5,292,661)
