The Orpet lab at WSU-TFREC is monitoring pear pests at seven commercial locations in the Wenatchee Valley in addition to the WSU research center orchard (‘Sunrise’) near Rock Island (Figure 1). At each location, one block follows our phenology-based IPM guidelines and another block follows standard conventional management. We are also monitoring organically managed blocks at three of the locations. All blocks contain mostly Anjou and Bartlett trees planted >50 years ago, except for Rock Island, which was planted in 2007.

How we Sample
We sample pear psylla adults and natural enemies with beat tray taps. In spring, we collect buds to monitor psylla eggs and nymphs. In summer through fall, we collect leaves to monitor psylla eggs and nymphs, mites, and earwigs.

Use pesticides with care. Apply them only to plants, animals, or sites listed on the labels. When mixing and applying pesticides, follow all label precautions to protect yourself and others around you. It is a violation of the law to disregard label directions. If pesticides are spilled on skin or clothing, remove clothing and wash skin thoroughly. Store pesticides in their original containers and keep them out of the reach of children, pets, and livestock.
YOU ARE REQUIRED BY LAW TO FOLLOW THE LABEL. It is a legal document. Always read the label before using any pesticide. You, the grower, are responsible for safe pesticide use.
