3-Sulfonylisoxazoline Derivatives As Novel Herbicides

A series of novel 3-sulfonylisoxazoline derivertives show good herbicidal activity against annual weeds. 3-sulfonylisoxazoline derivatives, consisting of isoxazoline and benzene rings, have unique physicochemical properties that enable them to provide stable efficacy under flooded rice culture systems and to prevent the risk of leaching into groundwater. Optimization of these compounds as a new herbicide for use in rice culture has led to the discovery of Fenoxasulfone. In this chapter, the structure activity relationship, influence of physicochemical properties and biological activities of Fenoxasulfone are reported.
