An active holiday weekend is predicted across much of the corn-growing region as a low pressure system deepens across the western Plains states and moves northeast into the upper Midwest and northern Great Lakes region by early next week. As high pressure moves into the southeastern United States during this same time, southerly winds are predicted to increase initially across the Plains states tonight where a Low corn earworm migration risk is in place mainly across Kansas and Nebraska. The southerly winds then expand to the north and east tomorrow night into Sunday morning, with Low migration risks into Iowa, Missouri, and far western Illinois in addition to Kansas and Nebraska. By late in the weekend and early next week, Low risks shift into the central and eastern corn-growing region with fields from eastern Kansas, Missouri, central and eastern Iowa, southeast Minnesota, Wisconsin, Illinois, Indiana, Kentucky, Ohio, lower Michigan, and also southern Ontario, Canada all at risk of seeing some isolated moth flights. Growers should be aware that no damage is predicted from any newly-arriving corn earworm moths at this time, but these early-season flights can have an effect on second generation moth flights later this summer when crop damage would be possible. Therefore, any intense flights should be noted especially for later in the growing season.
