Leafroller Sampling Made Easier
Monday Apr 15, 2024
Leafrollers are nearly impossible to sample when they are in the first 2-3 instars because they are so small. DAS provides intervals during which sampling should occur well ahead of time. To sample leafrollers...
Factors Affecting Bee Pollination of Tree Fruits
Monday Apr 15, 2024
Nearly 1,000 species of bees occur in the Pacific Northwest, but only a small number of species are useful in the pollination of orchard crops. Pesticide use and loss of appropriate nesting habitat have reduced the numbers of wild bee pollinators, leaving most of the pollination for commercial orchards dependent on honeybees. The success of honeybee pollination in tree fruits is affected by a number of factors, which in part can be manipulated by orchardists and beekeepers.
Degree-Day Models

Have you ever wondered why different pests have different degree-day sums? Here is why:
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.
