How to Read the Maps

Black Cutworm

September 19, 2017
No Risk

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

Corn Earworm

September 19, 2017

Low corn earworm migration risks remain in the forecast on a near daily basis as an active yet stagnant southerly wind flow pattern remains in place across at least a portion of the corn-growing region into next weekend. Low risks are predicted tonight into tomorrow morning from Nebraska, Iowa, and central Illinois north into South Dakota, Minnesota, and Wisconsin. Low risks then extend east into the southern Great Lakes area tomorrow night as a decaying cold front moves east to near the Mississippi River. By late week and into next weekend, Low risks are found mainly west of Lake Michigan as a low pressure system and cold front become stalled due to blocking effects of Hurricanes Jose and Maria in the eastern Atlantic Ocean. South to southwest winds should remain in place across this region for at least three days straight, and could lead to some new isolated moth flights into remaining processing and fresh market fields even at this point in the growing season.

Corn Rootworm

September 19, 2017
No Risk

No risk of corn rootworm damage is predicted in the next five days. Growers that did experience issues with rootworms this growing season, however, should plan ahead and consider adjustments to planting rotation or field practices for their 2018 crop.
