Researchers at the University of Illinois have found new insight into the mechanisms of how herbicide safeners turn on a defense "switch" in the plant to protect crops from herbicide injury.

DuPont Prevathon insect control powered by Rynaxypyr has received United States Environmental Protection Agency (EPA) registration for use on cereal crops, including wheat, most other small grains and sorghum. Prevathon was first registered in 2011 for use on cotton, corn, pasture and hay crops, including alfalfa. It provides control against lepidopteran worms, such as fall armyworm, true armyworm, corn earworm, sorghum webworm and loopers.

During the past couple years, the editors here at No-Till Farmer have had an eye on about six dozen no-tillers from the fair state of North Carolina that subscribe to our magazine.

One of the more common questions that I have been asked recently is whether the corn or soybean herbicide program will pose a problem for seeding fall cover crops.

Cover crop roller-crimpers have several advantages over mowing, in that fewer trips are required to suppress the cover crop, less energy is used, residues persist longer and the residue is neatly laid in one direction, facilitating planting.

Technology developed by researchers at The Ohio State University and the U.S. Department of Agriculture Agricultural Research Service (USDA-ARS) that will help manage the spread of one of the worst diseases affecting crops such as wheat and barley, has been licensed to Sci Protek, Inc., based in Vista, Calif.
