Description
The persistence, degradation and mineralization of methamidophos in a cotton field soil was studied in laboratory experiments. Results show that it is easily degraded, with a half-life of only a few days. At 30 deg. C, within 3 days. less than 25% of applied radioactivity was extracted in ethyl acetate:methanol (8:2 v/v). Thin layer chromatography showed that by the 15th day all the 14C-methamidophos had disappeared although nearly 16% of the radioactivity remained in the sample. In a study of mineralization, less than 9% of the radioactivity appeared as 14CO2 within 24 days. (author)
