I have had reports of white grubs causing significant stand loss in a handful of fields, while reports of black cutworm and wireworm damage have been infrequently reported this spring. Now would be a good time to evaluate the performance of cornfields with insecticide seed treatments. The systemic seed treatments (Cruiser, Gaucho, and Poncho) were widely promoted last winter as effective treatments for control of white grubs, wireworms and cutworms.
