Pesticide Residue Reports

In response to increasing industry concerns about meeting Maximum Residue Levels (MRLs) for pesticides in foreign markets, the 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.  The results of the most recent study on apple evaluating residues of eleven common insecticides and eight fungicides is available below, as well as reports from similar WTFRC projects on apple and cherry and a 2011 project on cherry insecticide residues conducted by David Haviland of the University of California Cooperative Extension.
