Cherry Residue Report Released

View Print Version

Written by Torry Schmitt, Washington State Research Commission

For the sixth 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 2016 report includes results for 27 commonly used active ingredients found in 16 insecticides/acaricides, 9 fungicides, and a potash & phosphite foliar fertilizer, as well as the influence of dilute (400 gal water/acre) vs. concentrate (200 gal water/acre) spraying.  The results of that study, as well as similar reports from previous years on apple and cherry are now available on the WTFRC homepage:
