Abstract/Contents: | "Pesticides associated with the turfgrass industry have been detected in stormwater runoff and surface waters of urban watersheds, raising concern of their potential environmental effects and a desire to reduce their transport to non-target locations. Runoff studies were conducted to compare the effectiveness of solid-tine versus hollow-tine core cultivation to reduce the quantity of pesticides transported with runoff from creeping bentgrass (Agrostis stolonifera) turf managed as a golf course fairway. The concentration of pesticides anticipated in a surface water receiving the runoff were calculated using data from this study and runoff volumes and pond dimensions recorded from a local golf course. Surface water concentrations were compared with levels known to be harmful to aquatic organisms. Key observations of the study were: Runoff volumes were less from turf managed with hollow- tine compared to solid-tine core cultivation. Greater quantities of pesticides were transported off-site with runoff from turf managed with solid tines. Concentrations of pesticides in a pond receiving runoff from turf managed with solid tines exceeded levels harmful to eight of 19 aquatic organisms evaluated. Replacing solid-tine with hollow-tine core cultivation reduced surface water pesticide concentrations to levels below harmful concentrations for most of these organisms." |
