Abstract/Contents:Discusses the development of a model for pesticide runoff from turf called TurfPQ. States that "it was reasoned that the interaction of chemicals, plants, and soils is similar for turf and field crops. However, when pesticide runoff values were calculated from these models for turf areas and compared with actual measurements taken in the field large discrepancies became apparent. These discrepancies arose because of fundamental differences in the ways that plants and soil influence pesticide behavior in crops and turf." Also discusses the testing of the model, stating that "TurfPQ predictions are fairly close to the actual measured pesticide runoff. There are exceptions, however. For two of the events, the model predicted pesticide runoff of approximately 20% of that applied, but the actual values were closer to 10%. On average, model results are about 50% larger than the measured values, which, by model prediction standards, can be considered very good." Describes how this model can be used for risk analysis. Also states that "during the 1990s, a great deal of scientific research on the issue [of pesticide runoff] was published, and the results of experiments and monitoring brought us to a much better understanding of the problem. We are now in the third, or problem-solving phase. With mathematical models such as TurfPQ to evaluate potential for pesticide runoff, we now have the tools to evaluate alternative chemicals and management strategies to help safeguard the environment."
