In response to increasing industry concerns about meeting Maximum Residue Levels (MRLs) for pesticides in foreign markets, the WTFRC initiated studies in 2011 in apple and cherry to develop some 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 2023 study in apple which included 17 insecticides/acaricides, 6 fungicides, and 1 plant growth regulator in two distinct application scenarios in a modern high-density ‘Gala’ orchard. The results of that study are available below, as well as similar reports from previous years on apple and cherry.
