When exposed to soil, ethiofencarb is moderately mobile and remains within the ground. It has been found to have a half-life of 2 weeks under greenhouse conditions. When added to water, it typically does not associate with the sediment, and can remain unchanged in an acidic environment, while it is hydrolyzed in an alkaline one. When dissolved in water, ethiofencarb is readily photodegraded by sunlight. Ethiofencarb could be transported from place to place in the environment through various natural waste pathways.〔 Carbamate groups are hydrolyzed to produce phenols and the ''N''-methyl group undergoes hydroxylation. Sulfur is rapidly oxidized to give ethiofencarb sulfoxide. As stated above, ethiofencarb is stable in acidic conditions, but hydrolyzes when in the presence of a base. It was found to rapidly hydrolyze at pH conditions of 9 and 12. When subjected to sunlight, the main products that resulted from photodegredation are 2-hydroxybenzaldehyde and 3-methylbenzo()oxazine-2-4-dione. The main reaction to occur is the precession of ethiofencarb to its sulfide. When in plants, ethiofencarb is close to optimum lipophilicity as the plant breathes. The chemical is metabolized to a sulfoxide, to a sulfone and then hydrolyzed to a phenol sulfoxide and a phenol sulfone.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ethiofencarb」の詳細全文を読む スポンサード リンク
