University of Kentucky’s Nursery Crops team recently developed an IPM program with the goal of providing new nursery producers with intensive training in pest management. It includes a curriculum and companion manual for a 6-month program, a Deciduous Tree Production IPM Calendar, and a workshop series covering mapping, monitoring, action thresholds and recordkeeping, as well as diagnosis, biology, and management of insects, pathogens and weeds. In 2005 a new component was added: weekly scouting of selected nurseries whose management and cultural practices range from infrequent or no spraying, to frequent pesticide applications. Population levels of key pests and related impact on plant aesthetics and health are documented at each visit. The IPM Calendar is used to focus scouting efforts. Pests and diseases being scouted include spider mites, soft scales, trunk- and shoot borers, leafhoppers, bagworms, Japanese beetle, fire blight, powdery mildew, verticillium wilt, bacterial leaf scorch, southern blight, and others. The scout catalogs digital images and organizes weekly pest data, providing timely information for nursery producers. Results from the first growing season of the scouting program will be discussed.
