Black Cutworm
After a brief break in the black cutworm migration risks, the next low pressure system developing in the Plains states brings back the next window of opportunity mainly for isolated moth flights into the central and eastern corn-growing region over the weekend. South to southwest winds are expected to increase once again from the southern corn-growing region into Iowa, Illinois, eastern Minnesota, and Wisconsin by tomorrow night into Saturday morning. Low risks are in the forecast across this area. As a cold front begins to push east by late Saturday into Sunday, the risk area shifts east into Illinois, Indiana, Ohio, lower Michigan, and far southwest Ontario, Canada. No additional risks are in the forecast at this time, but growers with emerging corn should continue to regularly scout fields as black cutworm flights have been more numerous and generally heavier this spring so far, and some damage to fields not normally seen will be possible where those flights were particularly heavy.
