Alert Details

Black cutworm migration risks will continue through midday Thursday ahead of a southeastward-advancing cold front. Low risks are in place tonight from eastern Nebraska as far east as Ohio and north into Minnesota, Wisconsin, lower Michigan, and southwest Ontario, Canada as south to southwest winds and rather warm temperatures persist especially across the central and eastern corn-growing region. Moderate risks enter the forecast tomorrow night into Thursday morning from eastern Wisconsin into lower Michigan and southern Ontario, Canada as this is the area favored for potential problems next month with later-planted corn. Low risks extend from roughly the I-35 corridor in Iowa and Minnesota east into the western Appalachians. No additional risks are predicted after midday Thursday, but growers all across the corn-growing region should be scouting fields as black cutworms are more numerous in some areas than in the past due to some rather intense moth flights over the last month and a half to two months.
