Why Monitor Slugs in Wisconsin?

Slugs are increasingly appearing as a potential challenge for Wisconsin growers who use conservation cropping practices. Shifting climate patterns, alongside the increased adoption of reduced tillage and cover crops, suggest that slugs may be finding more favorable environments to thrive.

SlugNet is working to determine how these factors influence pest populations and crop health, helping us improve pest management in Wisconsin’s conservation cropping systems.

Project Support

We are looking for volunteers throughout the state of Wisconsin. The more coverage we have, the better we can understand geographic variations in slug populations and damage risk to crops.

If you are interested in volunteering or have questions, contact Dane Elmquist, UW-Madison Extension Conservation Cropping Outreach Specialist, and Laura Flandermeyer, UW-Madison Extension Pest Management Outreach Specialist.
