Prolonged drought brings dry conditions and the potential for a surge of grasshopper populations that can hurt pastures, rangeland and hay production. Grasshoppers thrive in hot, dry weather, but can pose a threat any year. They are one of the most destructive insect pests forage producersface.

“Grasshoppers are eating machines that want the grass you have worked so hard to produce,”says Gerald Hobson, range and pasture specialist with DuPont Crop Protection. “Early awareness is your advantage, so scout pastures and initiate control measures early. Grasshoppers are much easier to manage in their susceptible nymphal stages than once they’re fully grown. The earlier you control them, the less forage they will have consumed, so watch for favorable grasshopper conditions early in the season.”

Strategic insecticide application is one good way to control mounting or extreme grasshopper infestations, advises Hobson. Look for products with residual activity to manage populations even after the sprayer pulls out of the pasture.

Producers have a new grasshopper control option in 2013 with DuPontPrevathon® insect control, which helps reduce labor needs by offering long-lasting residual controland helps manage insect resistance due to its alternative mode of action compared to current standard treatments. Pasture and rangeland applications of Prevathon can be made right up to cutting and livestock can graze as soon as herbicide application has dried.

Always read and follow all label directions and precautions for use.
