Abstract

Black cutworm adults were caught in pheromone traps across Iowa in April and early May. From these collections, we can project the likely first cutting dates of seedling corn across Iowa. As reported in last week'sICM Newsletter, black cutworms could be large enough to cut corn now in the southern three tiers of counties. In addition, cutting could occur by May 8 in west central Iowa and by May 11 in central and east central Iowa. Farmers in the northernmost three tiers of counties could have larvae large enough to cut corn starting May 15.
