Some farmers looking forward to good crops because of spring rains are losing some of those crops to a new threat – army worms that have moved into territories that they don’t usually visit. They’re muching away on pastures, corn and wheat crops, in several north Missouri counties. Army worms usually like southwest Missouri. Entomologist Judy Grundler with the State Agriculture Deparamtent says insecticides can be used, but sometimes it might be best to just let them eat. She says the infestation is not likely to be repeated in those areas year after year. She says a series of circumstances is necessary to provide a good climate for them.
