We have found a few corn fields in the Bothwell and Strathroy area that have had above threshold numbers of WBC eggs. I strongly recommend that late planted corn fields that are not in full tassel yet be scouted this week and next. Given that we are at or close to peak moth flight, that means there are a lot more moths out, dating, mating and laying eggs. They will be most attracted to later planted corn fields that are not in full tassel or early planted dry bean fields at this point. Not all fields will have WBC activity in them so do not spray corn fields with insecticide unless the egg mass threshold has been reached.
Based on high trap catches this past week, here are other areas that should be scouted: Courtland, Ben Miller, Blyth,Varna, Seaforth, Mitchell, Watford
