Pest Management

The dry summers and cold winters of central Washington lead to fewer pests and diseases of tree fruits than in many other areas, making this region particularly well-suited for organic fruit production.  Yet key long-time problems persist, while new pests and diseases such as Spotted Wing Drosophila and Little Cherry Virus continually arrive. Key challenges for Washington organic fruit growers include codling moth, pear psylla, powdery mildew, and Spotted Wing Drosophila.
