Corn Earworm Increasing On The Eastern Shore

Corn earworm still seems to be the pest to watch right now.

Numbers seem to be high to the south of us and increasing on the Shore. Continue to monitor fields for theshold numbers before spraying as worm pressure is heavy in some locations and low in others.

Fall army worm pressure on the station seems to be dropping, although some small worms were seen, possibly indicating the beginning of a second generation.

Beet army worm flights continue to be high in the traps, but few worms have been seen in the field. Trap numbers seem to be skewed possibly due high thunderstorm activity during the evenings keeping flight counts low. See this week's table.
