Our wheat fields are beginning to dry down. Watch for clipping of heads from armyworms. Also watch for armyworms moving from small grain fields into corn fields. It seems every year we have local hot spots of armyworm infestations. Unfortunately, growers are caught off guard many times and realize they have a problem when it is too late. I have not seen any problems yet, but this is prime time for a problem to occur. Often a big clue that you may have a problem is if you see birds diving into your wheat field. The birds are generally feeding on the worms when this is happening. If you find armyworms they must be less than one inch to achieve effective control.
