Washington’s 2021 cherry pesticide residue study now available

The Washington Tree Fruit Research Commission Internal Program recently completed its 2021 study in cherry which included 12 insecticides/acaricides and seven fungicides, including a few new products.

The results of that study are available, as well as similar reports from previous years on apple and cherry; results of an ongoing WTFRC residue study in apple will be posted in September.

In response to increasing industry concerns about meeting Maximum Residue Levels (MRLs) for pesticides in foreign markets, the Washington Tree Fruit Research Commission (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.

Those results and other reports from previous years on apple and cherry, including summaries across multiple years of data, are available here.
