Cooperative Research and Development Agreements
...With James Nolen and Company, Warwick, RI, to develop traps and other
tools to monitor and control mosquitoes, biting flies and midges. Few chemicals
are now registered to control these pests, so alternatives are needed. Traps are
one option; they would reduce the need for spraying chemical insecticides in
residential and commercial areas. The company and ARS scientists will develop
and test a variety of traps and two chemical attractants, octenol and carbon
dioxide, as lures. Carbon dioxide is a universal attractant for mosquitoes,
flies and other insect pests, while octenol is found in cow's breath and
attracts certain mosquito and fly species. ARS contact: Daniel L. Kline

...With Perdue Farms of Salisbury, MD, to turn chicken feathers into a
biodegradable substitute for wood or synthetic fibers such as plastics or nylon.
By studying feathers in a magnetic resonance spectrometer, a device similar to
the MRI imagers used in hospitals for brain scans, an ARS scientist discovered
the properties that make the feather an engineering marvel. It has strong fibers
that are more absorbent than wood or plastic. A newly-developed, fiber
separation process uses less water, energy and chemicals than for other fibers.
Initially, the feather fibers will be used in disposable diapers, hospital wipes
and feminine hygiene napkins. Future products may include air filters, oil
filters, specialty papers and structural composites similar to fiberglass.
Feather fibers cost less than most wood or synthetic fibers. They also
distribute moisture more evenly, increasing the fiber's absorbency powers. And
they can be composted in anyone's backyard in three weeks, as long as
commercially available microbes are added. (Patent Application 08/175,077)

...With Tenneco Packaging, Inc., Canandaigua, NY, to develop biodegradable
containers made with wheat starch. Researchers will investigate techniques to
process the starch. That way, equipment used to make food and beverage
containers from petroleum-based plastics might produce inexpensive,
starch-derived substitutes. The research could lead to low-cost, single-use
containers readily disposable by environmentally sound methods such as
composting. This could spawn a new market for wheat starch and boost farm
income. ARS contact: Gregory M. Glenn Cereal Product Utilization

...With Advanced Information Management and Movement, Inc. (AIM), of
Starkville, MS, to determine if instruments designed for espionage and war can
be adapted to agriculture. Systems made to detect traces of dangerous chemicals
on battlefields may be used by agricultural computers to detect traces of insect
chemical scents, called pheromones, that signal an oncoming attack of pests. In
addition, catfish farmers could use this program to detect off-flavors in ponds.
Radar systems designed to detect troops and tanks could be used to measure
growth in cotton. Tools the U.S. Central Intelligence Agency uses to hear
distant conversations may pick up leaf movements when pests are feeding. Systems
designed by the National Aeronautics and Space Administration to chart weather
patterns may be used to detect plant stress and soil moisture when used with
non-piloted aircraft. ARS Contact: Jim McKinion

...With Sonoco Products, Inc., Hartsville, SC, to test colored plastic
mulches that can boost yields of tomatoes and other crops. Sonoco produced a
red plastic mulch based on a formula developed by ARS scientists, and the mulch
is now being marketed by Ken-Bar, Inc., Reading, MA. ARS research has shown that
red mulch stimulates plant growth more effectively than black mulch. Red mulch
reflects certain wavelengths of light that make the plant act like it's being
crowded by neighboring plants. In response, the plant puts more energy into
above-ground growth, including fruit. In preliminary field studies, tomato
plants grown with the red plastic produced 500 number-one fruit in the first two
and a half weeks of harvest--about 20 percent more than the 410 fruit from
plants grown with black mulch. Scientists are now testing the red mulch
formulation on tomatoes and other crops including strawberries and peppers in
Colorado, Kentucky, Maryland, Pennsylvania and South Carolina. ARS

...With Rishellco, Inc., of Crowley, LA, to create a low-fat alternative to
French fried potatoes using rice. ARS researchers have found that using rice
instead of potatoes lowers fat content in fries by up to 50 percent. Subtle
differences in the chemistry of rice seem to make it better at keeping fat out.
Rice fries can be flavored with onion or spices to make a tasty snack. The fries
will be made from fine flour, using a machine similar to those used in making
breakfast cereals. ARS Contact: Ranjit Kadan

...With the Canola Council of Canada, Winnipeg, Manitoba, to study canola
meal as an alternative protein source in channel catfish feeds. The canola would
be a partial or total substitute for more costly soybean meal. Researchers are
studying the catfish's growth, feed utilization efficiency, survival rates, body
composition, immune response and disease resistance in evaluating canola meal.
Switching from soybean meal to canola meal would hold down costs for fish
farmers and provide an expanded market for canola. Feed accounts for 40 to 60
percent of aquaculture production costs. ARS Contact: Chhorn Lim

Parasites Research, Auburn, AL (334) 887-3741
...With Dynamax, Inc., of Houston, TX, to automatically control irrigation
systems based on how much water is stored in the soil. Designed by ARS
researchers, a computer-operated system turns on water pumps only when there's
not enough water for plant roots to take in. An electronic pulse is sent through
a cable to stainless steel soil probes placed in the ground to varying
depths--from every couple of inches down to several feet. Water content in the
soil is then computed, based on the time it takes the pulse to travel through
the probe: The longer it takes, the more water available. The probes work in
most irrigated agricultural soils. Dynamax, which is now manufacturing the
system, will develop it further with help from ARS and Texas A&M University
researchers to control irrigation for cotton and other field crops. Another
likely use is automated greenhouse watering. It is expected that the system's
cost may be offset by labor savings and lower expenses from pumping water only
when needed. ARS contact: Steve Evett

...With Pioneer Hi-Bred International, Johnson, IA, to find genetic markers
that will allow scientists to "fingerprint" corn and other crops.
Researchers will focus on genetic markers called simple sequence repeats (SSRs),
patterns that are unique to an individual plant. The goal is to isolate and
automatically screen these SSRs in specific plant cultivars--giving each plant
its own individual "fingerprint." Such information will be helpful to
plant breeders, because they will know without question a plant's genetic
background when they breed new varieties. Germplasm curators can also use the
fingerprints when cataloguing their collections. Now curators often don't know,
or can't be sure, about the precise genetic identity and makeup of each cultivar
in their collections. Genetic "fingerprinting" could help solve these
problems. ARS contact: Stephen Kresovich Plant Genetic Resources
Conservation Unit, Griffin, GA (404) 228-7254
...With three commercial firms to test laboratory-designed compounds that
mimic natural pest-killing chemicals made by a wild tobacco plant. The
compounds, synthetic sucrose esters, quickly penetrate whiteflies and other
soft-bodied pests of many crops. The pests start dying within a half hour. An
ARS scientist designed the synthetic molecules, which consist of sugar with
attached fatty acids. The same components make up natural sucrose esters in
leaves of
Nicotiana gossei, a wild Australian relative of commercial tobacco.
Synthetic esters killed up to 100 percent of silverleaf whiteflies, aphids,
leafhoppers and mites in lab and greenhouse tests. In an initial field trial,
the esters cut whitefly populations by nearly half. The esters should be easy
and economical to mass-produce and, unlike some conventional insecticides, are
quickly and completely biodegradable. ARS scientists are testing the synthetic
sugar esters on field crops, including fruits and vegetables, under a CRADA with
Rohm and Haas Co., Spring House, PA. A CRADA with Fuller System, Inc., Woburn,
MA, will examine using the esters to protect ornamentals and greenhouse plants.
Tests with pecans and other tree fruit and nut crops will be conducted with
Griffin Corp., Valdosta, GA. The agency is seeking a patent on use of the
esters. ARS Contact: O.T. Chortyk Natural Products Utilization

... With BASF Corp., Research Triangle Park, NC, to test whether a plant
growth regulator made by that company can reduce the number of undeveloped
cotton fibers that cause imperfections when a mill dyes cotton. The regulator,
sold under the name PIX, is currently used throughout the cotton belt to reduce
plant height (so the plant uses its energy to grow bolls) and enhance boll
production. New tests will determine if the regulator has the potential to
prevent drought-induced damage in cotton grown in dry areas. Without irrigation,
western-grown cotton can develop more than its share of immature fibers. Texas A&M
researchers, also part of this research, will grow treated cotton plants with
and without irrigation. They will also grow control groups under similar
conditions. Then, ARS researchers will test the fiber quality of the harvested
cotton. ARS Contact: Gayle H. Davidonis
Southern Regional Research Center, New
Orleans, LA (504) 286-4273
...With instrument company Zellweger Uster, Inc., of Knoxville, TN, to use a
new electrical sensor to measure cotton fiber moisture during quality checks.
Originally developed by ARS researchers for cotton ginning, the sensor can be
used in other industries such as textile processing and cotton marketing
classification. By measuring and adjusting for moisture levels, the sensor can
help predict fiber strength and other fiber qualities. This reduces or
eliminates the need for a costly pre-classification conditioning process in
which cotton samples are held in a controlled environment for up to 48 hours to
restore natural moisture levels lost during ginning. ARS and Zellweger Uster are
validating a moisture measurement system for its eventual commercialization and
introduction into the cotton industry. (Patent Application 08/273,244) ARS
