Grasshoppers in Soybeans

While out scouting some soybean fields across Burlington County I was starting to see young grasshoppers, particularly in no-till fields. This is a good reminder to scout fields for grasshoppers the next few weeks. When we begin to plant double crop fields after wheat, growers should pay attention to grasshoppers. It is possible to have stand reductions from early grasshopper feeding. There are no good economic thresholds for grasshoppers. Treatments may be required if 30 to 40% defoliation occurs up to the pre-bloom stage.
