Alert Details

An active weather pattern is predicted to return to the corn-growing region beginning this weekend and likely lasting into next week, as well. The threat for black cutworm migration will increase especially as we move into next week when southerly winds and potential precipitation events may coincide and lead to at least isolated moth flights into portions of the corn-growing region. A Low risk has been introduced to the forecast for Sunday night into Monday morning from Missouri and Illinois as far north as Iowa, southern Minnesota, and southern Wisconsin ahead of a developing low pressure system in the Plains. As this system moves east early next week, the main focus for any migration will shift primarily into the eastern and southeastern corn-growing region, or from southeast Missouri and Illinois into Indiana, Ohio, and Kentucky. While there is no immediate threat to crops, growers should monitor traps and record when significant moth flights occur so a general idea of when black cutworm larvae may pose a threat to newly-emerged corn next month.
