Alert Details

No risk of corn earworm migration continues through next Monday. After Monday, however, Low risks are back in the forecast mainly across the central Plains states (Kansas and Nebraska) as high pressure in the Midwest begins to shift east and low pressure develops in the High Plains. Southerly winds at flight level are expected to develop enough at least in Kansas and Nebraska to warrant a Low risk for fields in those two states. The risk area is expected to expand eastward just beyond the forecast period, so growers are advised to keep this in mind as we move into next week as corn earworm populations are ready to move in the mid-south source regions – they just need a favorable weather pattern to do it. Growers all across the corn-growing region should continue monitoring fields for larvae pressure as earlier moth flights this summer move into new generational phases.
