ABSTRACT- The Hood River basin is a major tree fruit production region of Oregon, USA. As a result of detections of the organophosphate insecticides chlorpyrifos and azinphos-methyl in tributaries of the Hood River at concentrations that exceed water quality standards, a four year monitoring program was initiated in conjunction with efforts to encourage the adoption of pesticide best management practices (BMPs) designed to reduce stream loading. This community-based effort included the Oregon State University Mid-Columbia Agricultural Research and Extension Center, the Hood River Grower-Shipper Association, the Hood River Soil and Water Conservation District, the Hood River Watershed Group, the Confederated Tribes of Warm Springs, and the Oregon Department of Environmental Quality. The use of monitoring data as a focal point of stakeholder forums, and in educational efforts to encourage the adoption of pesticide BMPs will be presented, as well as BMP strategies that address the potential for pesticide impacts at the watershed scale.
Key words: watershed, pesticide
