Emerging Winter Wheat, Grasshopper Pests and Systemic Seed Treatment
The following information was prepared by Kevin Wanner (MSU Extension Entomologist). Emerging winter wheat can be particularly vulnerable to damage by grasshoppers. The larger adult stage grasshoppers are difficult to control and move into emerging winter wheat fields from surrounding grassy areas. Grasshopper treatment thresholds for emerging winter wheat are 3-7 per square yard within the field, or 11-20 per square yard around the margin. Populations in these ranges will require treatment.
