Identifying biologically-based paths reducing insecticide resistance in codling moth

Codling moth is the key pest in Washington apples, a $2 billion industry. WSU research suggests that reducing insecticide rates by 90% in conventional farms…

Deep sequencing SWD gut contents to reveal non-crop alternative host plants

Spotted wing drosophila (SWD) is a devastating pest of Washington soft fruits including cherries, blueberries, and red raspberries. Since its arrival in 2009, the cost…

Using alternative host plants to improve accuracy of forecasting models for pest aphids

Aphids are abundant, outbreaking insect herbivores that can deal considerable economic damage to cereals and legumes due to pathogens they transmit. While aphid-virus outbreaks can…

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 frequently mulched with polyethylene (PE), providing numerous benefits. However, PE mulch has negative environmental consequences since it can…

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

This BIOAg grant was used to support a postdoctorate, Dr. Louisa Winkler, to assist Dr. Lindsey du Toit, WSU Professor of Plant Pathology, prepare a…

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…
