Degradation of the Herbicide , Butachlor , in Soil

Abstract
|
|
|
|
Butachlor incubated for certain periods of time under the simulated, rather aerobic, rice-paddy conditions of two different soils exhibited two major degradation products. 2,6-diethyl-N-(butoxymethyl) acetanilide and a new product C in all cases, and a relativly small amount of another new product D named tentatively as 8-ethyl-2-hydroxy-N-(butoxymethyl)-3,4-dihydroquinoline in some cases. The supposedly microbial degradation seemed to proceed with incubation periods to some extent. An anaerobic incubation in the previous investigation showed 2,6-diethyl-N-(butoxymethyl) acetanilide as the major product, whereas the new product C with m/z 291 turned out to be the major one in the present condition. Structural elucidation of the products was done based on the fragmentation patterns of the given mass spectra and a possible pathway for their formation was postulated.
