Alert Details

As a strong low pressure system develops in the Plains states by late in the weekend and into next week, black cutworm migration risks will be on the increase with Moderate risks in the forecast on both Monday night and Tuesday night. Low risks are initially in the forecast mainly west of the Mississippi River Sunday night into Monday morning as southerly winds increase to the east of the low pressure system and also as high pressure drifts off into the southeastern United States. By Monday night into Tuesday, a very favorable pattern for migration is expected across a large portion of the corn-growing region, with Moderate migration risks in place from north central Kansas as far north as central Minnesota and Wisconsin, and mainly west of I-57 in Illinois. A cold front is expected to push southeast through much of the area by next Wednesday and Thursday, but Moderate migration risks will continue in the forecast mainly east of the Mississippi River Tuesday night into Wednesday. While there is no threat to crops at this point, growers should monitor traps next week and document peak flight times to be able to calculate an approximate emergence window later this spring.
