Pear growers in Washington's Wenatchee Valley face a sticky problem.Pressure is mounting from pear psylla — which produce a sticky, fruit-damaging honeydew — and mites as the pests becomeincreasingly resistant to the most commonly used insecticides.But efforts to break that cycle are now underway by a team of Washington State University researchers who launched two pear IPM projects this year to study pesticide effectiveness, encourage the use of biocontrols and explore pest repellents.
