Timing is everything when it comes to effective pest management. Knowing when a pest is susceptible to which kind of pesticide is the key for successful control.
What is DAS?
The Decision Aid System (DAS) is a collaborative project between WSU Extension, the WSU Agricultural Research Center, and partners in agricultural industries. The DAS is a web-based platform designed to transfer time-sensitive information to decision makers. We run insect, disease, disorder, and horticultural models to predict on-farm conditions in real time, and link these site-specific forecasts to appropriate management and pesticide guidelines.
