Scouting for Stalk Borers in Corn

June 12, 2015

Scouting should be underway in southern Nebraska for stalk borers in corn.  Begin scouting grassy field borders and corn at 1,300-1,400 degree days. Plan to make insecticide treatment decisions in corn when 1,400-1,700 degree days have occurred.

For more information on scouting and treatment, see Managing Stalk Borers in Corn.
