Introducing the WSU Pesticide Spray Record Evaluator
Saturday Mar 07, 2020
At some point, many of us have heard from a grower or friend that "it's been a really bad year" for the control of a certain insect pest or "it's so bad we're going to need to pull this orchard out of organic management." While there are many causes for flare ups of a pest population, it begs the questions, 'when were treatments applied?' and 'which treatments in the spray program had the greatest effect on the pest population'?

San Jose Scale Management
Wednesday Apr 01, 2020
San Jose scale is a relatively easy pest to control, but a dangerous one to leave uncontrolled. After a few years of infestation, limbs and even entire trees can be killed if heavily attacked, and high percentages of the fruit can be infested. Large trees are most often associated with scale problems, because of the suitable habitat they provide and the difficulty of obtaining good spray coverage. However, young trees can also develop a scale problem surprisingly quickly. San Jose scale is a pest that is easily prevented, but hard to control if the populations have built up too much.
What is DAS?
A collaborative project between WSU Extension and WSU Agricultural Research Center.
WSU-DAS is a web-based platform designed to transfer time-sensitive information to decision makers in the tree fruit industry. It runs insect, disease, disorder, and horticultural models to estimate the current status of the issue and links that to appropriate management and pesticide recommendations.
