April Shower Bring May... Insect Pests

Tuesday, May 19, 2020

As we head into late May, things are finally feeling like spring and the soil is warming up. With warmer soils come more productive growing days, but also a cozier habitat for pests, including wireworm!

This time of year, wireworms move up to the warmer top layers of soil, feeding on newly seeded or transplanted crops. In fields you know to be problematic areas for wireworm, consider growing a less susceptible crop and practicing crop rotation. Consider cover crops such as brown mustard and buckwheat to combat existing populations. Avoid planting highly susceptible crops such as cereals or potatoes in problematic areas.
