Alert Details

Low corn earworm migration risks are predicted for the next couple nights as a cold front pushes southeast through the corn-growing region. Despite the very favorable pattern for potential migration, at this point in the growing season there is not much, if any, risk to crops but early season flights can lead to greater pressure later in the growing season when crops will be at a susceptible stage to damage. Thus, it is still important to monitor traps to ascertain the level of flights even this time of year. Low risks extend from Kansas and Missouri northeast into Minnesota, Wisconsin, and points east tonight into tomorrow morning and then mainly east of I-35 to west of the Appalachians tomorrow night into Thursday morning. No additional risks are predicted after midday Thursday as the cold front continues to move southeast.
