Alert Details

Corn earworm migration risks are in the forecast the next two nights as a corridor of south to southwest winds sets up from Texas and Oklahoma north into at least the southern and portions of the central corn-growing region. With an increasing number of fields entering into silking/tasseling stages of the crop, more field corn will become vulnerable over the next few weeks as will a continued threat to vegetable and fresh market crops. Low risks are in place tonight into tomorrow from Kansas and Nebraska into Missouri, Iowa, and Illinois as southerly winds continue in this region. The Low risk continues tomorrow night into Thursday across these same states but a little further to the south (mainly along/south of I-80) and also a little further to the east into Indiana. Localized pressure may occur in these areas and growers are encouraged to monitor traps for new flights. Little to no migration risk is expected late week as at least a period of northwest flow is anticipated at that time.
