The fate of C6H514CH2SCON (sec C4H9)2 ([14C]Drepamon, applied in preemergence to overspreading water, was investigated in a system including soil, water, and rice plants. A product of microbiological oxidation was isolated from both water and plants and identified as HOOC14CH2SCON (sec C4H9)2, whose formation was strictly related to the presence of soil. Among the metabolites of [14C]Drepamon 2 compounds were identified by cochromatography with its chemical oxidation products as C6H514CH2S(O)CON (sec C4H9)2 C6H514CH2S(0)2CON C6H514CH2S(O)2CON (sec C4H9)2. The former showed unspecific herbicidal activity when applied to demineralized water as the only growing medium for both rice and barnyard grass. The selective action of Drepamon appeared to be unrelated to the level of this metabolite in the plant as a whole and is better explained in terms of different absorption and metabolism of the herbicide in the crop with respect to the weed.
