How to Read the Maps

Black Cutworm

September 23, 2016
No Risk

No risk of black cutworm migration is predicted in the next five days.

Corn Earworm

September 23, 2016
2016_9_23_cew_day1

A strong cold front is predicted to push across much of the corn-growing region this weekend and into early next week. Ahead of the front, south to southwest winds are expected to continue, and may pose an isolated corn earworm moth flight risk to remaining processing and fresh market fields especially in the northern corn-growing region to the north of I-80. Low risks are predicted tonight into tomorrow morning mainly west of I-35 from the Dakotas and northeast Nebraska into Iowa and Minnesota. As the front moves east tomorrow into tomorrow night, the Low risk shifts to the east, as well, and includes eastern Minnesota, northern Iowa, northern Illinois, and Wisconsin. Low risks remain in the forecast Sunday night into Monday morning mainly across the southern Great Lakes as gusty northwest winds envelop much of the corn-growing region to the west of Lake Michigan, thus ending the migration threat. Growers with crops still at susceptible stages should continue to monitor traps and take necessary action where needed.

Corn Rootworm

September 23, 2016
No Risk
