David Loberg Northeast Nebraska | We've had confirmed presence in our fields for 4 years now. First year was the 3-4 outside rows, then the endrows, then slowly across the field. They appear to be overwintering in the crop residue now. Last year we tried 4 passes of an insecticide on ditches/field as an experiment, still no lowering of pressure. Not sure how to treat at this point. In the bad spots we showed it was a 35-40 bu/ac loss. It's one of the major reasons we planted a %100 corn this year. Between palmer amaranth going to seed in field next to us last year and these things, tired of spending $80/acre in chem and herbicide costs and still struggling to keep a weed/pest free field. Between irrigation, spoon feeding N, a shot of insecticide and fungicide, 250 bushel corn is fairly easy. Beans can throw the whole basket at them and it's still a crap shoot if they'll do over 50 bu/acre.
