Interpretive Summary:

Technical Abstract: Prosulfuron is an active ingredient in a number of herbicides currently being marketed for control of annual dicots and some grasses in maize. The environmental fate of prosulfuron in soil was investigated as a function of sorption and biodegradation processes. Traditional equilibrium batch method sorption isotherm studies were conducted. A large soil collection, representing an extensive variety of soil properties, was used to determine which soil properties influence sorption. Biological transformation of prosulfuron was examined using a Mason jar soil biometer method. Included in the biometer study were measurements for mineralization and metabolism of the parent compound, respiration, and bound residue. The soils used for this study were selected to represent a range of soil pH values and organic carbon contents.
