Any Fresh Silking Corn in Fields Needs Protection: Corn Earworm Still a Threat to Late Corn in Maine

Monday, September 17th, 2012

Hurricane Isaac appears to have only caused a mild bump in pest numbers in Maine corn over the past week, and it is likely that cooler temperatures will slow pest activity in the coming days. Any silking corn remaining requires protection from corn earworm statewide, but fall armyworm and European corn borer are only at problem levels in a few sites. Read more>>

Corn Earworm Pressure Consistently High Across Maine

With continued southerly weather and thunderstorms passing through Maine, insect pressure has remained high, mostly due to corn earworm. At this point, every location is on at least a 4-day spray interval, with some locations on 3-day intervals. For many growers, the youngest corn has reached the silking stage as the corn season begins to come to a close. Warm weather will continue to help corn mature rapidly and insect pressure will likely remain relatively high. Read more>>

Warm weather in Maine has pushed corn maturity along rapidly and supplies are picking up. A steady flow of weather from the south, including some heavy showers in some areas, is keeping corn earworm pressure very high in most fields this week. Several locations are now on a recommended 3-day spray interval, which we don’t typically see until early fall when tropical storms start moving through Maine.

Corn harvest is in full swing across most of Maine after the warm weekend weather. Insect pressure has increased, especially from corn earworm with many locations being placed on 4-day spray intervals. European Corn Borer pressure has remained low with the exception of a few northern locations, and fall armyworm appears to be slightly on the rise, but hasn’t exceeded thresholds anywhere. With the prospect of southerly thunderstorms throughout most of the next week, insect pressure is not expected to decrease.

Corn harvest is still spotty as growers work through the erratic early corn and hope for better uniformity and quality with the main season crop. Many fields received just enough rain to get a break from irrigation this week. A little bit of weather coming up from the southeast coast appears to have bumped up local corn earworm populations, so silking corn is likely to need protection, especially in the southern and coastal areas of the state.
