Fruit and Ornamental Disease Management Testing Program

Online Resource

The primary purpose of the fruit and ornamental disease management testing program is to provide Oregon growers, Extension Faculty, and Field Representatives with unbiased information on the relative efficacy of fungicides, fungicide schedules or cultural practices for control of plant diseases. Treatments evaluated are not restricted to chemical fungicides and may involve use of cultural controls, biological controls and other innovative materials that show promise in controlling disease. Our objective is to broaden the scope of methods used to reduce crop loss due to diseases and to service the diverse management practices of Oregon growers. The results are compiled and sent to county agents, field people, company representatives, and to interested growers directly. The information gained from these trials is used to formulate disease control recommendations for Oregon's diverse agricultural crops.
