Slugs, primarily the gray garden slug, Deroceras reticulatum, have become a major impediment to growing corn and soybean as well as other crops using no-till production practices in parts of the eastern U.S. and Canada. As conservation tillage becomes more common, slug problems are expected to increase in both severity and geographic area. Proper management of slugs includes correct identification, the sampling of slug populations throughout the year, and employing various cultural practices. The use of molluscicides either as a preventive or therapeutic tactic is often necessary. An IPM approach to management of slugs in field crops is described.
