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
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.
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.
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.
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.
Inducement of malolactic fermentation using Lactobacillus plantarum in musts and wines from the Pacific Northwest.
The completion of both alcoholic and malolactic fermentation in red wine are essential the quality and stability of red wine and to its commercial success in the market.
It takes a village: Understanding barriers to regional cooperatives for pest and disease management
abstract An individual grower’s response to pests and diseases in their vineyard can have consequences for an entire growing region. Collective action strategies can help align disease responses to achieve…
Developing a Spray-Induced Gene Silencing (SIGS) method for the control of Grape Powdery Mildew (Erysiphe necator)
abstract The project aims to develop a methodology to turn off specific grapevine genes (susceptibility genes ) and Powdery Mildew-related genes essential for the pathogen’s life cycle. Since September 2021,…
Sweet SWD control: non-target effects and field trials with erythritol
abstract Erythritol is a non-caloric sugar used in artificial sweeteners such as Truvia and is safe for human consumption. Formulations with erythritol have induced mortality among spotted-wing drosophila (SWD) adults…
Identification of the fungal pathogen causing dry-berry and development of tools for rapid identification
Identification of the fungal pathogen causing dry-berry and development of tools for rapid identification abstract Dry-berry, a disease of raspberry and blackberry, whereby immature green berries are killed, was first…
Biology and Management of Cutworms in Washington Vineyards
abstract Cutworms are capable of causing severe damage in vineyards during the early spring months when vines buds and tender shoots are at their most vulnerable. Damage to buds can…
Detection of wine faults using the electronic tongue
abstract Faulted wines pose a serious economic problem to the wine industry, these off flavors can cause consumers, new to a region or variety, to reject that region entirely. Wine…
Identification of the fungal pathogen causing dry-berry and development of tools for rapid identification
Identification of the fungal pathogen causing dry-berry and development of tools for rapid identification abstract Dry-berry, a disease of raspberry and blackberry, whereby immature green berries are killed, was first…
Development of a wine yeast to prevent stuck fermentations
abstract High and low nitrogen levels in grape must can cause sensory and economic issues in the production of fine wine. The amount of available nitrogen in the fermentation is…
New Opportunities for Control of Bindweed in Blackberries
abstract The objectives of this project were to determine: 1) whether the herbicide Quinclorac can be used to control or suppress bindweed in blackberries without impacting crop performance; and 2)…
Connecting Breeders to Producers: Regional on-Farm trials of Strawberry Cultivars and Elite Selections
Connecting Breeders to Producers: Regional on-Farm trials of Strawberry Cultivars and Elite Selections abstract There has been an ongoing need to have consistent strawberry variety grower trials to determine the…
Optimizing Nutrient Management for Organically Grown Blueberries in Eastern Washington
abstract Washington is an important producer of organic highbush blueberries (Vaccinium corymbosum L.) with over half of the production concentrated east of the Cascade Range. Soils used for blueberry production…
Developing Pinot noir crop load metrics that are adaptable to Winery site and wine quality production goals II-grape and wine quality evaluation
Back to all Developing Pinot noir crop load metrics that are adaptable to Winery site and wine quality production goals II-grape and wine quality evaluation abstract In the Pacific Northwest…
Fungal Populations in PNW cranberries as it Relates to Fruit Rot
abstract Cranberry fruit rot is an important disease complex comprised of at least 15 different fungal pathogens that can occasionally cause losses of 15-30% at harvest. It has traditionally been…
Systematic evaluation of sulfur use for management of grape powdery mildew
Back to all Systematic evaluation of sulfur use for management of grape powdery mildew abstract Powdery mildew is a fungal disease that can affect a variety of crops, but it…
