For the fourth consecutive year, the Washington Tree Fruit Research Commission has conducted a trial 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 decisions with respect to concerns about Maximum Residue Levels (MRLs) in foreign markets.

The 2014 report includes results for 30 commonly used active ingredients found in 18 insecticides/acaricides and 10 fungicides, as well as the influence of two popular rain protectants on residue persistence.

The results of that study, as well as similar reports from previous years on apple and cherry are now available on the WTFRC homepage: www.treefruitresearch.com
