Corn earworm and squash vine borer numbers rise this week, growers need to take action

Corn Earworm

Corn earworm numbers have jumped this week, so sweet corn growers in much of the state need to keep fresh silking corn protected.

Squash Vine Borer

At the same time, we are starting to see squash vine borer numbers going up, at a time of the year when they usually go down. This appears to be the start of a second generation, which sometimes occurs in New Hampshire. When it does, the fruit are significantly attacked, especially hard squash and pumpkins in the warmer parts of the state.
