Alert Details

Moderate corn earworm migration risks are predicted tonight into tomorrow morning across central and eastern Nebraska, western Iowa, eastern South Dakota, Minnesota, far western Wisconsin, and southeast North Dakota. South to southwest winds are predicted to increase and prospects for precipitation are also present, leading to the potential of numerous drop zones across the Moderate risk area as a cold front pushes to the southeast. Moderate risks continue in the forecast tomorrow night into Friday morning, as well, across eastern Iowa, southeast Minnesota, central and southern Wisconsin, and northern Illinois as the corridor of stronger south to southwest winds shifts southeast with the cold front. Low risks extend into lower Michigan, northwest Ohio, and Indiana tomorrow night, as well. Low risks are then found mainly east of I-55 in central Illinois and into the eastern corn-growing region by Friday night into Saturday as the cold front pushes through the remainder of the corn-growing region. Growers with crops at susceptible stages should continue to monitor traps closely and scout fields.
