Release of 'WA 38,' new apple cultivar
an eye-catching, large, dark red apple with a remarkably firm, crisp, and juicy texture that also stores well. The apple has outstanding eating quality, exceptional flavor, ample sweetness, and sufficient tartness to impart real character. Our feeling is that when it comes to the combination of taste, texture, and beauty, “WA 38” has no equal in today’s marketplace. Washington State University Research Foundation (WSURF), the licensing arm of WSU, desires to find an exclusive licensee to manage its commercialization (more...)

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.

Visual Guide to Adult Stink Bugs
The Brown Marmorated Stink Bug is an invasive species native to eastern Asia where it is considered a major economic pest of soybeans and woody plants. Its presence in the US was first discovered in 2001 in Pennsylvania, and has since spread west with detections as far as California and Oregon. As in Asia, this pest is known to attack our high valued tree fruit crops as well as vegetables and small fruit. (more at PMTP)

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...)
