Fungal microbiome associated with grapevine trunk diseases in Oregon vineyards
Grapevine trunk disease (GTD) is a disease complex that consists of the largest group of fungal pathogens causing disease and progressive vine decline. Due to the complex nature of GTD...
Reducing leaf chlorosis of ‘Concord’ vines: Effects of FeEDDHA and rootstocks
‘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
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?
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
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
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
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
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
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)
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.
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
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
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
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...
Detection and monitoring of Tomato Ringspot Virus in red raspberry and Xiphinema americanum.
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
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
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
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...
Development of Aphid Resistance Resources in Black Raspberry
Black raspberry is a well-known Pacific Northwest specialty crop with unique flavor and nutritional attributes, but also unique vulnerabilities. A prominent threat facing the crop is the aphid-vectored Black Raspberry...
Diversity of Pseudomonas syringae and diagnosis and management of bacterial canker on blueberry
Bacterial canker caused by the bacterial pathogen Pseudomonas syringae is characterized by killed buds and stems. The disease can be severe when environmental conditions support growth and infection of tissues...
