 Abstract
Several physicochemical properties including water solubility, vapor pressure, and hydrolysis of bistrifluron benzoylphenylurea insecticide developed in Korea, were measured based on OECD guidelines for testing of chemicals and Toxic Substances Control Act Test guidelines. Water solubility was low showing 30 at and in hydrolysis study, half-life at was 10.9 days (pH 9.0) and was stable in pH 7.0 solution. At hydrolysis rate was 20.6 days (pH 7.0) and 1.5 days (pH 9.0). The vapor pressure of bistrifluron was not obtained from vapor pressure experiments at because the bistrifluron was not detected. Therefore, the vapor pressure was determined to be torr which was calculated to apply the detection limit (50 ng) of bistrifluron. And this value is suggests it would not give environmental contamination by volatilization.
