Alert Details

Isolated corn earworm moth flights will be possible this week especially across the eastern and southeastern portion of the corn-growing region as no less than two separate low pressure systems affect the corn-growing region this week. Low risks are predicted tonight into tomorrow morning mainly across southeast Missouri, Illinois, and Indiana where southwest winds should be the strongest and precipitation at least more scattered earlier in the night. Additional Low risks are in the forecast a little further west, or from eastern Kansas and Missouri into Illinois, Indiana, and western Kentucky tomorrow night as the next low pressure system organizes over Kansas tomorrow night into Wednesday morning. Low risks remain in the forecast mainly across the eastern corn-growing region Wednesday night into Thursday morning as a cold front pushes through the region. No additional risks are predicted after midday Thursday. Growers should be aware that these early corn earworm migrants do not pose any threat to crops at this point, but they could remain in the corn-growing region and produce generations later this summer.
