Do you need enhanced corn insect control?

Corn hybrids with insecticidal traits have helped protect yield often lost to early-season bugs in your field. But in cases of heavy insect pressure or increasing populations of secondary pests, you may need a bit more protection than just traits. 
So how do you decide if you would benefit from a soil-applied insecticide on top of your corn hybrids? 
Consider the following questions:
  • Is there heavy rootworm pressure?
  • Do I need to manage insects with multiple modes of action?
  • Is there heavy white grub pressure?
  • Are past wireworm pressures a concern?
  • Is there potential for early-season weed competition?  (Pest population growth accelerates in early weed cover.)
  • Is there a history of grape colaspis?
  • Do I plan to plant early?
  • Are cutworms a threat?

Answering “yes” to one or more of these questions indicates that you should seriously consider adding a soil-applied insecticide to your insect management program to maximize yield potential.
