What are the next steps and priorities for filling information gaps for pesticides?
One of the most important gaps to be filled is improved tracking of pesticide use in agricultural and non-agricultural areas, including amounts, locations, and timing. Given the direct relations between pesticide use and occurrence, improvement in the extent, frequency, and quality of quantitative data on agricultural use—and development of comparable and reliable data sources for nonagricultural pesticide use—would have major benefits for assessment and management of pesticides in streams and ground water. In addition, long-term consistent data for assessing trends is essential for tracking water-quality response to changes in pesticide use and management practices, for providing early warning of unanticipated problems, and for updating and improving models. Evaluations also are needed to make direct links between management practices—such as irrigation methods, subsurface drains, integrated pest management, and retention of wetlands and buffers—and the concentrations and transport of
