Wisconsin Pest Survey

​​​farm fields overlooking a farmsteadThe Wisconsin Pest Survey monitors crops in the state for insects and diseases. Our team of specialists uses scientific survey methods to watch for and report pest trends that affect agricultural production. We look for new and invasive pests, and collect data to support export certification of Wisconsin crops and plant products such as logs and nursery stock.

Survey activities involve sampling plants and soil for diseases and identifying insects. Our Plant Industry Laboratory diagnoses plant diseases and nematodes, tiny worm-like soil pests. 

We report results in the Crop Survey Reports listed here. During the growing season, we also report results weekly in the Pest Bulletin to help producers make pest-control decisions.​​

The pest survey is supported by federal funding through the USDA Cooperative Agricultural Pest Survey.
