NEW Model: Fruit Growth

Tuesday June 05, 2018 8:38am
The range of fruit sizes at harvest can now be predicted well before harvest with the new fruit growth model. The current model makes predictions for Gala, Red Delicious, and Cripps Pink.

Use Pesticides Wisely to Avoid Resistance

Tuesday May 01, 2018 4:04pm
Repeated use of pesticides with the same mode-of-action used in the orchard can accelerate the development of insecticide resistance. WSU recommends that when you choose insecticides, keep track of which ones are being used so that you alternate materials with the different modes-of-action (shown in DAS) between generations.

Fireblight Prediction and Management

Tuesday May 01, 2018 2:49pm
Many consider blight an apparently random curse, and part of the game a pome fruit grower must play. As outbreaks do not occur yearly, damage always seems to be somebody else's problem, until it suddenly appears in your orchard.

Leafroller and Codling Moth Movement During the Season

Thursday April 19, 2018 12:00am
Movement of codling moth and leafrollers into your orchard can be the start of serious damage. Both CM and leafrollers can easily fly 5-7 miles in a single night and their reproduction is as high as those that do not fly. Although 5-7 mile flights are common, the likelihood of the moths coming to your orchard in high numbers is directly related to wind speed, distance from the source, and the environment in between the source and your orchard.

NEW Model: Honey Bee Foraging

Wednesday April 11, 2018 12:39pm
Are the weather conditions favorable to bee foraging activity? The new honeybee foraging model predicts bee activity by looking at past, current, and forecast weather conditions.
