2019 Cherry MRL Report Available

For the ninth consecutive year, the Washington Tree Fruit Research Commission has conducted studies to provide the Northwest cherry industry basic information about residues of commonly used pesticides.  These studies are intended to help growers and consultants make more informed pest management decisions with respect to concerns about Maximum Residue Levels (MRLs) in foreign markets.  The 2019 report includes results for 17 commonly used active ingredients found in 12 insecticides/acaricides and 5 fungicides, as well as the effects of spraying dilute (400 gal water/acre) vs. concentrate (200 gal water/acre).  The results of that study and similar reports from previous years on apple and cherry including summaries across multiple years of data are now available on the WTFRC homepage:
