New insecticide available
DuPont Crop Protection announces a label expansion for Prevathon insecticide into cereal crops, including wheat, other small grains and sorghum. Environmental Protection Agency registration for use on these crops came in January. Prevathon is labeled for use 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 can now use Prevathon for insect control across a full range of crops," says James Hay, North America business director for DuPont. "Many of the worm pests that attack corn and soybean fields also attack sorghum and small grains. As these pests move from one crop to another, Prevathon adds flexibility to a grower’s integrated pest management program, while helping to protect developing crops."
Hay says farmers see an immediate stop to insect feeding plus residual control for 14 to 21 days, with a preharvest interval of 14 days on cereal crops and sorghum. Its unique single mode of action versus conventional insect control products gives farmers another tool to combat the insect
resistance cycle, he adds.
Breakthrough in Scab Resistance
Wheat breeders in Minnesota and the Dakotas have made big strides in developing wheat varieties with moderate resistance to Fusarium head blight (FHB).
Each state has variety options that feature moderate or intermediate resistance to scab without sacrificing other key traits such as yield, test weight, straw strength or protein content. Breeders say U.S. Wheat and Barley Scab Initiative (USWBSI) funding and support accounts for a big part of these advancements. Currently, university and USDA scientists from two dozen states receive research funding from USWBSI.
"A coordinated national approach is more effective than piecemeal state-by-state or region-by-region efforts for continued progress," says James Anderson, University of Minnesota spring wheat breeder. "USWBSI funding keeps some of the best minds in small grains cereals in the U.S. engaged in FHB research."
These varieties give farmers new opportunities for profit, adds Mohamed Mergoum, North Dakota State University spring wheat breeder.
"These cultivars have been dominating the U.S. spring wheat region, generating hundreds of millions of dollars for wheat growers," he says. "Likewise, the wheat industry and the export market have benefited from high-quality and FHB-resistant cultivars."
The monthly World Agricultural Supply and Demand Estimates report from USDA is one of the most hotly anticipated reports of the year. It is a must-see when developing a crop marketing plan. The latest report offers a look into the complex world market. Who’s producing more grain, who’s producing less grain and how will that affect prices?
