A very active late September and early October weather pattern is likely, and despite the calendar and many crops indicating that the end of the growing season is near, with so much late and re-planted crops and also processors and fresh market growers with intentionally late planted crops still present, corn earworm migration risks remain in the forecast right through early next week until a cold front passes and the overall weather pattern changes. Low risks are present tonight into tomorrow morning from Nebraska and eastern South Dakota east to Lake Michigan, and generally across the southern Great Lakes region tomorrow night into Saturday as the first low pressure system and cold front move southeast. A brief break is then anticipated Saturday into Saturday night, but already southerly winds will be returning to western areas at that time and Low risks are warranted across much of the central and northern corn-growing region beginning Sunday night and lasting into Tuesday morning until the second front clears the area. Growers with crops at susceptible stages to corn earworm damage should continue monitoring traps and scouting fields until either the crop is harvested or is no longer considered to be in a critical growth stage where corn earworm damage could occur.
