The influence of specific edaphic environmental factors on the detoxication and subsequent degradation of N-Butoxymethyl-2-chloro-2', 6' diethylacetanilide (butachlor) was evaluated under greenhouse and growth chamber conditions. Detoxication of butachlor, as measured by bioassay with barnyardgrass, was significantly enhanced by increasing temperatures to 32 C, making the soil alkaline, flooding, introducing relatively high levels of organic matter and by allowing exposure of more than four weeks. Total degradation of butachlor to C02 was enhanced also by high temperatures and length of exposure but was inhibited to a certain extent by flooding. Soil produced metabolites, of which three were soluble in …
