The Washington Tree Fruit Research Commission announced the publication of the 2022 pesticide residue study for apple.
This year’s apple study included 15 insecticides/acaricides, six fungicides and one plant growth regulator in two distinct application scenarios in a modern, high-density Gala orchard.
That 2022 report, as well as previous summaries and annual reports from similar projects on apple and cherry, is now available on the research commission website at: treefruitresearch.org/pesticide-residue-studies.
Since 2011, the research commission 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The results of the 2022 cherry pesticide residue study will not be published due to flawed results with the potential for misinterpretation. If you are interested in learning more about the cherry study results, contact Tory Schmidt at: email@example.com.
