TFREC is the research and extension center of Washington State University dedicated to the tree fruit sciences. Located in the primary fruit producing region of the world, the center features a cooperative, multidisciplinary approach to tree fruit production in the 21st century.
Managing Pollination Risks with Mason Bees
Tuesday, November 18, 2014, 10am-1230pm, WSU Tree Fruit Research and Extension Center
Pollination is essential to tree fruit production. Risks to successful pollination include poor weather, hard-to-pollinate varieties, decline in honeybee availability, and escalating honeybee costs. Mason bees, particularly blue orchard bees (Osmia lygnaria), are a well-researched alternative pollinator that can be combined with honeybees (or used alone) to reduce pollination risks. Both research results and grower experience have shown that they can lead to yield increases in some situations, and other benefits are being investigated. Come learn about these alternative pollinators and how they might fit your operation from the four leading mason bee companies in the country. They will introduce you to the behavior and performance of the bee, and how it can be used in a managed program (versus relying on wild populations) with a positive return on investment. Background on the bees can be found at http://crownbees.com/.

Hows and Whys of Soil Testing
October 29, 3—4PM, Large Conference Room@WSU-TFREC; live video to WSU Prosser and Yakima Valley CC
Dr. Joan Davenport will discuss soil testing, a tool to estimate nutrient availability over a single growing season. She will discuss the chemistry behind traditional soil testing, what a soil test does and does not tell you, and provide some information about other types of tests that are being promoted for use. Dr. Davenport will also discuss how soil moisture and water management influence nutrient availability as well as root system considerations.
Dr. Davenport's discussion can be viewed during the scheduled time at WSU-IAREC (Prosser) and at the Yakima Valley Community College - College of Nursing in room 111 of Sundquist Hall (map; pdf). It will also be available on-line after a later date.
This is the second in a series of educational opportunities focusing on soils in perennial fruit systems. A session on “Roots” is planned for the Wash. St. Hort. Assoc. meeting on Dec. 3, 2014, in Kennewick, and a more general workshop on “Building Soils for Better Crops” is planned for Dec. 10, 2014, in Moses Lake.(more; pdf...)

Little Cherry Disease…..a growing concern for Washington sweet cherry growers
Trees with little cherry disease produce cherries of small size and poor flavor making the fruit unmarketable. This disease has been present at low levels in Washington State since the 1940s, but became increasingly evident during 2011-2013 resulting in unpicked limbs/trees, tree removal, and even whole orchard removal. Little cherry disease has been verified in commercial sweet cherry orchards in Grant, Chelan, Douglas, and Okanogan counties. To learn more about little cherry disease management, spread, and current WSU research, go to http://www.tfrec.wsu.edu/pages/LCD.

TFREC welcomes physiologist to faculty
Dr. Lee Kalcsits joined 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
Potential March harvest for greenhouse peaches

Colored nets over your orchard, and your investment
Recent arrivals at TFREC, Drs. Desmond Layne and Stefano Musacchi, plan to establish research plots to test new advances in protecting high value orchards with netting. In a recent commentary in Growing Produce, Dr. Layne describes orchards in Europe and South Africa using netting to reduce sunburn, hail, and pest damage. Forthcoming changes in national food safety regulations may impact the ability of fruit growers to use overhead evaporative cooling for sunburn protection. (download pdf)

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...)

Since the first commercial plantings of Gala apples in the 1980s, the popularity of this cultivar has grown exponentially until today Gala is the second largest cultivar grown in Washington. This new WSU Extension Fact Sheet identifies typical practices and corresponding costs of a modern, well-managed Gala apple orchard. It indicates current trends in the industry, and as such, can be helpful in estimating the physical and financial requirements. (fact sheet)
