Black cutworm potential cutting dates

Posted by Russel Higgins -

Based on catches of Black cutworm adults across Illinois initial projections for BCW cutting dates have been posted by Kelly Estes, State Survey Coordinator at the University of Illinois. Corn fields most likely to exhibit damage are those that were overgrown with grasses or winter annual weeds during adult egg laying. Weeds that are attractive to egg-laying moths include chickweed, shepherd's purse, peppergrass, and mustards such as yellow rocket. Winter wheat is also a likely host. I'm encouraging farmers in northern Illinois to be diligent and scout as we near the projected May 20th date for NE and NW Illinois.  More information on the Black cutworm can be found in this fact sheet.
