Wenatchee Valley Pear IPM Project (WVPP) 1999 Summary Report
Author: Ted Alway
Published: 1999
Summary: The Wenatchee Valley PearIPM Project has the objective of demonstrating, in commercial orchards, the increased use of biological control of key pear pests to develop more effective and economical pear pest control programs. The need for such a program has been brought about by two principal factors: 1) the cost of effective pear pest control has risen greatly in recent seasons, due to new, more expensive pesticides, pest resistance and favorable conditions for pest development, and 2) new and increasing regulations regarding pesticide use and availability has increased the importance of creating effective pest control programs that rely less upon broad spectrum insecticides.
