Scouting for Western Bean Cutworm Egg Masses

All late tasseling fields should be checked now… WHAT TO SCOUT: prioritize scouting of late planted fields or other fields that have not tasseled or have tasseled later than the majority of fields in your area. WBC are showing a very strong preference for pre-tasseled fields, so any pre-tassel fields will have many more egg masses laid in them. This doesn’t mean you won’t get any eggs laid in a field that is in tassel, but the majority of eggs will be laid in pre-tassel fields (if available) so start there. They also seem to be showing some preference for fields with sandy soils. Make sure you scout at least 20 plants in each of 5 different areas of the field. The more plants you check the better.
