Welcome

The WSU Pesticide Spray Record Evaluator will allow you to enter your spray records for a given site to evaluate how that spray program affected the population of the pest compared to an untreated population.
You can evaluate your spray program for several pests. You can also evaluate the effects of your spray program for one pest on another if it occurs on the same crop and is susceptible to the same pesticides – for example how a conventional codling moth program would affect oblique-banded leafroller.
