More information and help files for the tool are available at AWN after user login.


El Niño alert for this summer or fall

The NWS-Climate Prediction Center has issued an El Niño watch for this summer and fall.  In some years, insect developement, fruit maturity, and apple sunburn have been affected by El Niño conditions.  Follow on the TFREC Climate Prediction links and use the WSU-DAS horticultural models.


TFREC welcomes physiologist to faculty

Dr. Lee Kalcsits will join the WSU-TFREC faculty March 1 in the position of plant physiologist. Lee grew up on a small acreage in Saskatchewan, Canada where he developed his passion for horticulture and trees. He completed his B.S. in Plant Sciences majoring in Horticulture at the University of Saskatchewan while also gaining experience in plantation forestry and domestic fruit breeding during the summers. He then completed his M.S. in tree ecophysiology looking at interactions between autumn temperature and dormancy development in hybrid poplar. He recently completed his PhD at the University of British Columbia where he worked towards developing a new integrated isotope approach to measure nitrogen-use traits in poplar and other plants. Since July, 2013, he has been working at the Centre for Forest Biology at the University of Victoria exploring the interactions between nitrogen source preference and temperature in tree seedlings. He is looking forward to introducing and developing new approaches for addressing physiological problems associated with tree fruit production


Workshop on biological control in tree fruits

The WSU Tree Fruit Research & Extension Center is offering a hands-on workshop on biological control in tree fruits. This workshop is free, but signup is required (find registration link below). Participants can receive pesticide recertification credits. Sessions will be held Friday, 28 February and Wednesday, 12 March 2014 in Wenatchee and Friday, 21 March 2014 in Prosser. This biocontrol workshop will consist of 2 modules; you can choose to participate in both modules or just in Module 1.

Module1: Understanding the basics of biological control and learning to recognize natural enemies in the orchard: discuss general principles and examples of biological control in orchards, review key natural enemy groups and features used for their identification, and practice insect identification skills.
Module 2: Applying new biocontrol information: monitoring, models, and pesticide effects on natural enemies: learn about new and traditional ways to monitor for natural enemies, explore how knowledge about natural enemy phenology helps in pest management, understand how pesticides affect natural enemies, apply new information in a practical exercise

First 2011 Spotted Wing Drosophila

We have the first 2011 captures of SWD in eastern WA. We are recommending that growers in this region begin crop protection sprays when their cherries reach a susceptible stage (blush).

The WSU recommendations for Spotted Wing Drosophila control in eastern Washington cherries are now available. We will be deploying traps throughout April, and will send out alerts for each region’s first catch of SWD this spring, as well as posting them on the SWD website. Western WA small fruit growers can find specific information on the Mt. Vernon web site.

Note: the SLN (Special Local Needs, or 24(c)) for spotted wing drosophila control with Entrust was updated June 28, 2011.

WA 2: first WSU apple variety

After 15 years, the WSU apple breeding program has released its first apple cultivar. Currently known as ‘WA 2’ was released because of its outstanding eating quality, appearance and productivity and therefore it’s potential to be a successful cultivar in Washington State.

It is attractive with an orange-red to pinkish-red blush over a yellow background and has large and conspicuous lenticels which usually make it easily distinguishable from other cultivars and add to its overall pleasing appearance. The fruit has outstanding texture, being very firm, crisp and juicy and loses very little firmness in storage and on the shelf (more...)
