Alert Details
Corn rootworm hatch risks continue from western Illinois east into central and eastern Illinois, central Indiana, and by this weekend into western and central Ohio. Growers in these areas should monitor their fields closely for signs of corn rootworm hatches and small larvae as soil temperature heat unit accumulations have met, exceeded, or will exceed initial hatch thresholds during this forecasting period.
