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.
