Reducing Pesticide Runoff In Urban Waterways

Abstract:
Treatment strategies focused on reducing the amount of fipronil applied and the amount fipronil and its metabolites detected in the water runoff. Directed applications around the perimeter of the structure, narrow pin-stream applications, and no spray zones reduced the amount of fipronil detected. Alternative formulations such as foam may also have potential in reducing the amounts of fipronil in the water runoff. A standard treatment that avoided the driveway and garage provided satisfactory control and the lowest levels of fipronil in the water runoff.
