| Abstract/Contents: | "Accurate estimation of turf pesticide runoff using models requires critical data inputs that are lacking. This study is part of an on-going project designed to address some of these data needs. We are investigating the effects of grass species, mowing height, and plot size on pesticide runoff from warm season turfgrasses. In this preliminary study, we applied 2,4-D (2,4-dichlorophenoxy acetic acid), flutolanil (trifluoro-3`-isopropoxy-o-toluanilide) and chlorpyrifos (O,O-diethyl hexahydro-4,7-methanoindene) at maximum label rates to two turfgrasses maintained as golf course fairways on a Brookville silty clay (fine montmorillonitic, thermic Aquic Chromudert). The turf species used were Mississippi Pride bermudagrass (Cynodon dactylon [L] Pers. X Cynodon transvalensis Burtt-Davy) and Meyer zoysia grass (Zoysia japonica). Twenty four h after pesticide application, simulated rainfall was applied at 2.2 ± 0.2 cm/h to the plots to generate runoff. On average, 22 ± 6.7% of applied 2,4-D, 1.8 ± 0.7% of applied flutolanil and 0.2 ± 0.8% of applied chlorpyrifos were measured in runoff. Maximum concentrations observed in runoff were 823 ± 126 ppb for 2,4-D, 1386 ± 60 ppb for flutolanil and 21 ± 7 ppb for chlorpyrifos. Soil organic carbon coefficients were 73 ml/g for 2,4-D, 576 ml/g for flutolanil and 3551 ml/g for chlorpyrifos, indicating weak adsorption potential for 2,4-D, moderate to strong adsorption for flutolanil and high adsorption for chlorpyrifos. Runoff results were well correlated to the soil-water distribution coefficient for the Brooksville silty clay." |
