| Abstract/Contents: | "Previous pesticide runoff models were developed for agricultural crops and are difficult to apply directly to turfgrass. To address this, researchers at Cornell University developed a runoff model, TurfPQ, specifically designed for turfgrass. The model was tested using published plot runoff data for 52 runoff events in fours states, three soil hydrologic groups, four different turfgrasses ( bermudagrass, creeping bentgrass, tall fescue, and perennial ryegrass) and six different pesticides (2,4-D, chlorpyrifos, diazinon, dicamba, dithiopyr, and mecoprop), mean predicted pesticide runoff was 3.2% of that applied compared with an observed mean of 2.1%. It appears that the accuracy of TurfPQ meets or exceeds that of more complex models (e.g., EPIC, GLEAMS, OPUS), and predicted the dynamics of the pesticide events well (R2 =0.76), the model was used to simulate runoff of two common turf fungicides, chlorothalonil (Daconil) and iprodione (Chipco 26019) from creeping bentgrass fairways in Boston, Philadelphia, and Rochester. These simulations allowed researchers to estimate quantities of these pesticides that could reach nearby surface waters thus enabling them to environmental risk to two species, rainbow trout and Daphnia magna (water flea)." |
