Reducing leaf chlorosis of ‘Concord’ vines: Effects of FeEDDHA and rootstocks

July 25, 2024

‘Concord’ vineyards in central Washington are plagued by a leaf chlorosis problem that occurs around bloom. It significantly reduces vine size, vine uniformity, and productivity, and even causes vine death....

Differentiation and detection of blueberry scorch strains

July 25, 2024

The Blueberry scorch virus (BlScV) was first identified in Oregon and Washington in 1987, and later in British Columbia in 2000. It has been found in over 140 blueberry fields...

Can humic acids improve production in mature organic northern highbush blueberry?

July 25, 2024

A 3-year study was conducted to investigate the effects of adding humic acids to an organic blueberry fertigation program. The objective is to see if adding organic-approved humic acids to...

Optimizing Nutrient Management for Organically Grown Blueberries East of the Cascade Range

May 2, 2024

Northern highbush blueberry (Vaccinium corymbosum) production east of the Cascade Range is an important contributor to the national supply of organic blueberries. However, native soil conditions are alkaline, have high...

Trials of Advanced Raspberry selections to evaluate suitability for IQF processing and to promote adoption

April 5, 2024

A new cultivar, ‘Cascade Premier’, and an advanced selection, ‘WSU 2188’, were compared with industry standard cultivars under commercial production and processing conditions. The cultivars were evaluated for Individually Quick...

Taking proof of concept to wide-scale field use: The OSU high- performance dendrometer

March 5, 2024

During the duration of this project researchers refurbished the electronics of all 32 dendrometers and manufactured carbon fiber parts for the new 3 spring design. Two deployments were completed, one...

The effect of soil parameters on plant-parasitic nematodes of wine grapes in Washington and Oregon

March 5, 2024

Plant parasitic nematodes are costly pests that cause global crop loss of over $100 billion dollars. Previously it was thought that the large populations of ring nematode in Oregon and...

Risk assessment of nematode-transmitted viruses of small fruit crops in the Pacific Northwest

February 25, 2024

The Pacific Northwest (PNW) maintains a $840 million small fruit industry susceptible to nepoviruses, which are viruses that are transmitted by dagger nematodes. The association of viruses with nematodes is...

Developing a Spray-Induced Gene Silencing (SIGS) method for the control of Grape Powdery Mildew (Erysiphe necator)

February 21, 2024

Powdery Mildew development in vineyards in the Pacific Northwest is one of the greatest impacts to grape and wine quality and the economic health of a grape grower is severely...

Inducement of malolactic fermentation using Lactobacillus plantarum in musts and wines from the Pacific Northwest.

February 21, 2024

The completion of both alcoholic and malolactic fermentation (MLF) in red wine are essential to the quality and stability of red wine and to its commercial success in the market....

Botrytis Bunch Rot: Where, When, and What to use

February 15, 2024

From 2020-2022, eleven sites from nine different vineyards in Oregon, and four in Washington were surveyed for Botrytis by sampling grape inflorescence and developing fruits, vineyard floor debris (prior year...

Epidemiology and Management of Plant-parasitic Nematodes in Winegrapes

February 2, 2024

Nematodes are root feeding organisms that can cause direct damage and can also be a virus vector. Nematodes can severely limit the successful establishment of vines and vineyards and impact...

Evaluating Commercially Available Technologies for Weed Management in Blueberries: Saturated Steam and Rotary Brush

October 20, 2023

Washington and Oregon account for 85% of national raspberry production and 15% of worldwide production. Growers from Washington and Oregon harvest over 80 million pounds of raspberries on about 12,000...

Heat stress in wine grapes: acclimation and potential mitigation

October 20, 2023

Heat stress poses challenges for the sustainable production of premium wine grapes in the Pacific Northwest. The intensity of heat waves has been increasing. For example, the series of heat...

Enhanced IPM of Rose Stem Girdler, an Emerging Pest of Pacific Northwest Caneberries

May 2, 2023

Rose stem girdler (RSG) is an invasive beetle pest of caneberry crops that is becoming increasingly problematic for Pacific Northwest (PNW) growers. It has progressively become naturalized throughout the northern...

Development of alternate fertilization programs to mitigate nutrient problems found in long-term organic production systems

May 2, 2023

In long-lived organic blueberry production systems, nutrient imbalances caused by some fertilization and mulching practices can reduce yield and plant health. The ability to balance nutrient levels and thus improve...
