Pest Update July 27 – 31, 2020

Haying continues to happen and a reminder that insect populations from hayed fields will migrate into new fields. Scouting is encouraged of any nearby fields as populations will increase.

Grasshoppers have been noted from 4th Instar – Adults, the pest project will be starting its annual grasshopper survey.
