A Wisconsin entomologist says farmers need to keep a close watch for black cutworms now. Bryan Jensen with the University of Wisconsin’s integrated pest management program tells Brownfield the state ag department’s pheromone trap network has indicated several significant flights of black cutworm adults in Wisconsin.
Jensen says the traps are a great early warning tool but not always a good predictor of field damage. “When you’re dealing with adult catches, sometimes, you never quite know what’s going to be happening in the field and that’s why regardless of these blacklight trap catches and pheromone trap catches, spending time in the field is really important right now.”
Jensen says he recommends scouting fields that would be more likely to have problems first.
