2019 Apple Pesticide Residue Report Now Available

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 2019 study in apple which included 10 insecticides/acaricides and 5 fungicides in two distinct application scenarios in a modern high-density ‘Gala’ orchard. The results of that study, as well as previous reports from similar projects on apple and cherry are now available on the WTFRC homepage:
