Alert Details

Corn earworm migration possibilities will continue on a near daily basis especially across the southwestern portion of the corn-growing region right into early next week as persistent south to southwest winds remain in place to the east of low pressure systems in the Plains and high pressure in the Tennessee River valley. Only Low risks are predicted given the source region is in a less than optimal location in Texas and Oklahoma versus further east into the Mississippi River valley, and also crop stage for the majority of plants is not at a stage where damage is expected. Nonetheless, vegetable and fresh-market growers located from Kansas north into South Dakota, Minnesota, and east into southwest Wisconsin and Illinois should continue to monitor for the possibility of isolated moth flights in the next 4-5 nights. A few moths may also make it as far north as the I-94 corridor in central and northwest Minnesota as well as North Dakota late in the weekend and early next week.
