Alert Details

As a low pressure system and cold front moves southeast through much of the corn-growing region by mid-week next week, at least some modest south to southwesterly winds in advance of the front may result in some isolated corn earworm moth flights late in the weekend and into next week, as well. Low risks are predicted Sunday night into Monday morning mainly west of I-35 from Kansas into Nebraska, western Iowa, the Dakotas, and Minnesota. As high pressure moves slowly southeast early next week, southerly winds are expected to expand east, with Low risks then pushing further east into Wisconsin and Illinois next Monday night and Tuesday. Low risks continue in the forecast next Tuesday night and Wednesday especially across the southern Great Lakes and eastern corn-growing region. Growers with crops still at susceptible stages to damage should be monitoring traps and scouting fields as some larger moth flights occurred last weekend especially in portions of the northern corn-growing region. Additional more isolated flights will be possible in the next five days, as well, per the forecast.
