Grower surveys of pest management practices in Washington State vineyards were conducted in 1997 and 2005. Grower responses substantiate that real improvements in the adoption of integrated pest management practices have been made since 1997 in the control of arthropod pests and diseases in Washington State vineyards. Broadcast organophosphate insecticide use has been eliminated. This represents an annual 11,000 kg reduction in OP usage. Disease forecasting models and the increased use of petroleum derived spray oils has improved disease control and reduced the use of other fungicides for the control of powdery mildew. Details will be given during the presentation on how practices have changed and how growers respond to various outreach efforts.
