RosBREED2: Disease Resistance Plus Horticultural Quality
Imagine the day when you can commercially grow fruit, nut, and ornamental cultivars that have high consumer acceptance, are highly productive, and are resistant to one or more major diseases. That hope may be one big step closer as scientists work together on a newly funded federal grant. On Oct. 2, the National Institute of Food and Agriculture Specialty Crop Research Initiative (SCRI) announced that a team working on the genomics, genetics, and breeding of crops from the Rosaceae family had been awarded funds for the first year of a $10 million, five year competitive grant.

Cider apple orchard costs
WSU Extension faculty recently released a downloadable fact sheet, 2013 Cost Estimation of Establishing a Cider Apple Orchard in Western Washington. The guide examines the feasibility of establishing and producing cider apples. An accompanying Excel spreadsheet is available at the Extension Economics website, http://www.tfrec.wsu.edu/pdfs/P2933.xls.
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.

Orchard diseases, finding a solution in the genes
Dr. Desmond Layne, in a May 2014 American Fruit Grower column, provides a summary of the progress toward breeding tree fruits for both disease resistance and superior fruit quality. Armed with tools that only recently became available, breeders have become more creative, accurate, and efficient (more; download pdf).
Predatory mites in northwest orchards
Information on predatory mites recently discovered in northwest orchards has been added to the Orchard Pest Management web articles.
New timing tools for blossom thinning
A timing tool for blossom thinning on apples is available on the WSU AgWeatherNet (AWN) this spring. Based upon the rate of growth of pollen tubes, the tool differentiates the good and bad timings for effective blossom thinning with lime sulfur. More information and help files for the tool are available at AWN after user login.
Potential March harvest for greenhouse peaches
Washington has the potential to produce greenhouse peaches with harvest as early as March if Washington growers follow a method used in China. Dr. Desmond Layne, WSU-TFREC horticulturalist, reported on practices used in 30,000 acres of greenhouses at the Jan 21st North Central Washington Stone Fruit Day (more at Capital Press)

Fruit Testing Technology Tries to Catch Up With Our Mouths
"pierce a peach with your teeth....too soft, you’ll pull back before any spoiled mush slips past your gums...too hard, you probably won’t even take the first bite." October Modern Farmer features an interview with WSU-TFREC researchers Katherine Evans and Desmond Layne discussing technology to duplicate what every fruit lover knows about just right firmness.
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)

Fruit quality matters...to the consumer...to the bottom line of the producer
In a new article in American Fruit Grower, Desmond Layne tells the story of Peter Welacky Sr., a Hungarian immigrant, and how he taught his young picking crew the importance of fruit quality...that if you have "peaches and when picked tree-ripe, and handled carefully, and displayed nicely, they would literally sell themselves."

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)
