Alert Details

An active weather pattern is predicted to remain in place across a large portion of the corn-growing region through the next several days. Even though the majority of crops are not at a susceptible stage to damage from corn earworms specifically this time of year, some isolated moth flights will still remain possible the next few nights. These moths may result in new generations that develop later this summer that may affect crops at that point, so monitoring is still warranted at this time. Low risks are in place tonight into tomorrow morning generally south of I-90 and west of I-57, or from southern South Dakota, Minnesota, and Wisconsin and from Illinois on west into the Plains. Low risks continue in the forecast tomorrow night into Saturday morning from I-35 in eastern Kansas into northwest Missouri, Iowa, and southeast Minnesota east into lower Michigan, Ohio, and Kentucky. No risks are predicted after Saturday morning, but again growers are advised to monitor for new moth flights and take note if a capture is observed despite the early time of the growing season.
