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.
Prevathonwas 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.
With this newest registration on cereal crops and sorghum, growers now can use Prevathon for insect control across a full range of crops, said James R. Hay, North America Business director of DuPont Crop Protection. Many of the worm pests that attack corn, soybeans, cotton and pastures or hay fields, also attack sorghum and small grains.
In addition to insect control, Prevathon helps break the insect resistance cycle with an alternate mode of action versus older insect protection standards, said Hay.
Three years of field trials showed Prevathon provided nearly 100% worm control on sorghum heads 11 to 15 days after treatment, and more than 83% worm control in sorghum whorls 5 to 7 days after treatment. It causes immediate cessation of insect feeding, provides residual control for 14 to 21 days, has no grazing or haying restrictions on range and pasture grasses and alfalfa, and has a preharvest interval of 14 days on cereal crops and sorghum.
