Corn insect scouting clinics scheduled for this Friday, August 5

Plan to attend in St. Joseph or Rosemount

Corn insect pressure is changing! Northern corn rootworm have re-surged after a 10-year absence. Extended diapause problems have re-surfaced. Western corn rootworm resistance to Bt corn persists, European corn borer has re-surfaced after a 20-year absence and is making its presence known in conventional corn. How can a grower stay on top of these shifting insect problems?

Ken Ostlie, Extension Entomologist, with the assistance of Ph.D. graduate students Trisha Leaf and Edwin Benkert, will be holding two corn insect scouting clinics this week. The primary focus will be on corn rootworms with an opportunity to review European corn borer scouting. The St. Joseph location features predominantly northern corn rootworm and European corn borer while the Rosemount location features western corn rootworms and Bt resistance.

The clinics will cover scouting techniques, management options and thresholds plus provide hands-on experience in scouting using both visual counts and sticky traps. The discussion on the role of scouting in managing these dynamic insect threats should interest corn producers, agronomists and retailers alike.
