Larry, a good start would be to get rid of Roundup Ready which eliminates row crop weeds and bugs.. Talking with a 50 year farmer In SW Iowa about 5 tears ago, he had not seen a grasshopper in 4 years.
Well, it's not because of Roundup Ready crops. I plant RR corn, soybeans and cotton, and see hordes of grasshoppers some years. Some springs they are so bad we have to spray just emerged cotton to keep it from being completely wiped out by grasshoppers.
Take it from a lifelong farmer ....... Don't listen to everything every farmer says. If he implied that glysophate (Roundup) got rid of grasshoppers he is a nut.
