Thank you for visiting the Washington Tree Fruit Research Commission’s website. We support applied science to improve the financial and ecological sustainability of Washington’s tree fruit industry through innovative horticulture, pest and disease management, postharvest programs, and development of new technologies which efficiently deliver premium quality fruit to consumers.
Since 2011, the WTFRC has conducted studies in apple and cherry to generate pesticide residue data for commonly used insecticides and fungicides to help Washington growers make more informed choices about their spray programs. The WTFRC Internal Program recently completed its 2017 study in apple which included 7 insecticides/acaricides and 5 fungicides, as well as considering the effects of spraying concentrate (100 gal water/acre) vs. dilute (200 gal water/acre) in a modern high density orchard. The results of that study are available below, as well as similar reports from previous years on apple and cherry.
