Producers are encouraged to scout both corn and wheat for armyworms and potential feeding. Kevin Black, Insect and Plant Disease Technical Manager with Growmark Inc., reported that a field of corn (Putnam County) planted into a rye cover crop had received some defoliation by armyworms. Kelli Bassett, a Field Agronomist with DuPont Pioneer, observed (May 30) some armyworm feeding in scattered wheat fields across Macoupin and Montgomery counties.
