There is ongoing concern about the increasing number of herbicide resistant weed biotypes. As a result, the Weed Science Society of America (WSSA) developed five lesson modules on herbicide resistant weeds. This project provides New York Certified Pesticide Applicators the opportunity to enhance their knowledge about herbicide resistance, and about the advantages of utilizing integrated approaches to weed management while earning recertification credits. Ten pre- and post- test questions were written for each of the five WSSA lesson modules. Once the New York State Department of Environmental Conservation (DEC) approves these lesson modules and test questions, they will be available to applicators through the Cornell On-Line Recertification system managed by the Pesticide Management Education Program (PMEP).
