Degree-Day Models

Have you ever wondered why different pests have different degree-day sums? Here is why:
How to Effectively Manage Codling Moth
Thursday Apr 08, 2021
Without any intervention, codling moth numbers increase about four-fold from generation to generation. Therefore, targeting the first generation is important to reset the population size to a minimum. Control measures for subsequent generations can be adjusted to the local pest pressure indicated by trap counts.
San Jose Scale Management
Thursday Apr 01, 2021
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.
