Sustainable agriculture in Washington State drives to be economically viable while being environmentally responsible through improvements made to both on- and off-farm practices. Effective and efficient monitoring programs are an essential piece of policy implementation and adaptive management for sustainability. In our previous BioAg research, we hypothesized that remotely sensed data are underutilized in these […]
Buckwheat is a common summer cover crop in western Washington (WWA) that provides exceptional weed suppression and pollinator support to crop rotations. However, buckwheat is rarely grown to seed in WWA due to lack of access to high performing and characterized varieties. Release of high-yielding public varieties could transform the value of buckwheat in rotation, […]
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 can provide control equivalent to full rates by improving predator conservation that supplements chemical control. However, fears of promoting insecticide resistance has prevented industry adoption. In organic blocks, codling moth […]
The organic agriculture sector in Washington achieved an estimated $776 million in farm-gate sales in 2019. Regular, accurate statistical data on this sector are not available from the standard government sources, thus WSU has been compiling data continuously since 2004. Growers, processors, consultants, businesses and others in the organic sector need solid data upon which […]
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 and intensity of insecticide programs for these crops has dramatically increased. SWD adults generally develop and invade crops from unknown alternative host plants, complicating management. Despite great efforts to identify […]
There is much we do not know about the soil microbiome and little has been done to explore soil microbe x plant genotype x environment interactions. Classical wheat breeding strategies focus on yield and aboveground metrics, but recent work has identified soil and rhizosphere (area of the soil influenced by roots) characteristics that can be […]
Climate change, extreme weather events, and soil degradation all mean that we are increasingly asking our soils to do more with less – infiltrate and store more water with less organic matter and weaker soil structure. A recent focus on soil health provides the opportunity to reverse this trend, but it will require a sound […]
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 have catastrophic impacts on crops, we do not yet have reliable population models that predict the time and location for areas at high risk for aphid-virus outbreaks. Because these tools […]
As plant-mycorrhizal interactions are known to be context dependent, a better understanding of the conditions in which mycorrhizal fungi are beneficial to grapevine growth will help to inform vineyard management strategies aimed at incorporating biological inputs and improving agricultural sustainability. In a field experiment at WSU-Irrigated Agricultural Research and Extension Center (IAREC), I propose to […]
Forage production is the largest agricultural land use in western Washington supporting a diverse livestock industry. Poor grazing management and repeated hay removal, without amendment contribute to reduced productivity, encroachment of weeds, erosion, and inadequate forage quality to support animal health. This integrated research and extension project will address the WSU Sustaining Resources Grand Challenge. […]
