Alert Details

A low corn earworm migration risk is predicted for fields in eastern Kansas, much of Missouri, and west central into southwest Illinois overnight tonight into Tuesday morning. A low pressure system is predicted to track northeast through the Plains as high pressure moves into the southeastern United States. A respectable pressure gradient is predicted in between these two pressure cells which is likely to result in south to southwest winds occurring across especially the southern and central corn-growing region. With crops not at a critical stage where damage could occur and overall limited hosts, only a Low migration risk is predicted from eastern Kansas into southwest Illinois to cover the potential for an isolated moth flight. Otherwise, no corn earworm migration risks are in place for the remainder of the next five days as a dominant northwest to southeast wind flow pattern is predicted to return to much of the corn-growing region by mid-week and into next weekend.
