Reduction of Isoprothiolane Sulfoxide by Rice Plant in Relation to Metabolic Activation

Abstract

Isoprothiolane sulfoxide, an oxidative metabolite of isoprothiolane, is easily reduced to isoprothiolane by the living rice plant. The reduction is completed within 2 days after addition to the culture solution. Reduction of the sulfoxide may be important in activating a possible propesticide, isoprothiolane sulfoxide, and in ensuring the residual effectiveness of the pesticide, isoprothiolane.
