In Missouri, Plain producers (groups of conservative Anabaptist faith, including the Amish and Mennonites) are one type of underserved audience that has found a niche in vegetable production. The study reported here investigated the level of knowledge and use of Integrated Pest Management (IPM) gained over a 3-year period following implementation of Extension activities by the University of Missouri and Lincoln University, the two Missouri land-grant universities. Results indicate that Extension plays an important role in the observed increased use of IPM by the target audience and highlight the need to continue using traditional methods (e.g., printed documents, one-on-one interactions)
