Since 2011, the WTFRC has conducted studies in apple and cherry to generate residue data for commonly used pesticides to help Washington growers make more informed choices about their spray programs. The WTFRC Internal Program recently completed its 2023 study in apple which included 17 insecticides/acaricides, six fungicides, and one plant growth regulator in two distinct application scenarios in a modern high-density ‘Gala’ orchard. That 2023 report as well as previous summaries and annual reports from similar projects on apple and cherry are all now available on the WTFRC homepage.
