Rotating out of weeds and into soil health: Optimizing cover crops in three Columbia Basin organic production systems

Weeds cause extensive loss in agricultural production and are particularly damaging in organic systems. Control generally relies on mechanical cultivation which reduces soil carbon, decimates…

Impact of manure-derived fertilizers on bacterial community and antibiotic resistance genes in Washington red raspberry fields

Washington State is the number one producer of processed red raspberries in the nation. Raspberry growers in Whatcom County rely on dairy manure as a…

Can lignin degrading organisms reduce Verticillium wilt in pumpkin cropping systems?

Raised beds in pumpkin cropping systems are mulched with polyethylene (PE), but result in waste. PE mulch can remain in the soil and is costly…

Quantifying the Weed Seedbank Using Quantitative PCR and Soil Community Analysis

Quantification of  weed seedbanks is essential for the evaluation and improvement of integrated weed management systems by farmers and integral in the Sustaining Resources Grand…

Development of a USDA NIFA SCRI proposal to combat onion bacterial diseases across the US

Bacterial diseases have increased the risk of growing onions in the US. Efforts to limit losses to bacterial rot in fields, storage, and shipping have…

Breaking bindweed: Can plant growth regulators disrupt apical dominance, deplete a persistent bud bank, and improve the control of perennial weed species in specialty crops?

Field bindweed (Convolvulus arvensis) is notoriously difficult to manage in specialty crop systems, particularly those under organic production. Perennial species possess the abundant nutrient reserves…

Evaluating the Impacts of Border Vegetation Patterns on Multifunctional Biodiversity and Crop Production in Washington Blueberry

Herbaceous flowering or woody plant borders are controversial in commercial blueberry (Vaccinium corymbosum) production. Border vegetation has the potential to increase populations of native pollinators…

Examining microbial mediation of disease resistance, pollinator attraction, and crop yield in apple crops

The composition of microbial communities can have dramatic, but often unappreciated, impacts on crop production. In apple crops, surveys indicate that numerous microbe species colonize…

Biodegradable peptides as triggers of plant defense against pathogens and pests

Biologically active compounds derived from plants, e.g., peptide elicitors are known as a strong inducer of defense responses against pathogens and pests. Recently, the PI’s…

Impact of fungal root endophytes on Verticillium wilt using cucurbits as model hosts

V. dahliae (Vd) is a soilborne fungus that infects a broad range of economically important plants. Infection causes chlorosis and necrosis and yield loss due…
