Pesticide Residue Studies

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 2024 study in apple which included 12 insecticides, 3 acaricides, and 6 fungicides in two distinct application scenarios in a modern high-density ‘Gala’ orchard.  The results of that study are available below, as well as an updated summary of all WTFRC apple residue studies (2011-2024) and similar reports and summaries from previous years on apple and cherry.
