The environmental fate and safety of pesticides used in the management of recreational facilities is a critical issue facing the turfgrass industry. The purpose of this research was to determine the potential movement of certain pesticides following application to golf course greens and fairways. Greenhouse and outside lysimeters were constructed and leachate, exiting the base of the lysimeters, was collected and analyzed for transport of treatment pesticides. Herbicide movement from simulated fairways was determined following treatment of small plots having a 5% slope and sodded with 'Tifway' bermudagrass. The data indicate that less than 1% of the applied pesticides were transported in the leachate from the base of the lysimeters. Highest concentrations of analyses in the leachate were less than 5.0 micrograms L-1. However, higher concentrations (279 to 810 micrograms L-1) of the treatment herbicides were transported in the runoff water from the treated simulated fairway plots.
