Metabolism of Metolachlor by the Fungus Cunninghamella elegans

Archives of Environmental Contamination and Toxicology, 1997
The metabolism of metolachlor[2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-met hyl ethyl)acetamide]by the fungus Cunninghamella elegans ATCC 36112 was determined. Thesix metabolites identified comprised 81% of the total[14C]-metolachlor metabolized by C. elegans.

Influence of the Chemical Environment on Metolachlor Conformations

Journal of Agricultural and Food Chemistry, 1999
Metolachlor exists in multiple, different stable conformations in solution. Assignment of the NMR frequencies to chemical structure is a prerequisite to understanding the behavior of individual conformations. (1)H NMR experiments of metolachlor in different chemical environments identified the labile sites of metolachlor and environments that influence

Infiltration and adsorption of dissolved metolachlor, metolachlor oxanilic acid, and metolachlor ethanesulfonic acid by buffalograss (Buchloe dactyloides) filter strips

Weed Science, 2004
Vegetative filter strips (VFS) potentially reduce herbicide transport from agricultural fields by increasing herbicide mass infiltrated (Minf) and herbicide mass adsorbed (Mas) compared with bare field soil. However, there are conflicting reports in the literature concerning the contribution of Masto herbicide trapping efficiency (TE).

Effects of S-metolachlor and its degradation product metolachlor OA on marbled crayfish (Procambarus virginalis)

Chemosphere, 2019
Increasing production of energy crops in Europe, mainly maize and rapeseed, has altered patterns of pesticide use in recent decades. The long-term effects of S-metolachlor (S-M) and of its metabolite metolachlor OA (M-OA) at the environmentally relevant concentration of 4.2 μg L-1 and at 42 μg L-1 (ten-fold concentration) on marbled crayfish ...

Sunlight Photodegradation of Metolachlor in Water

Journal of Agricultural and Food Chemistry, 1994
The chemical and photochemical stability of the herbicide metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide] was determined in organic-free water and lake water containing various solutes. Metolachlor was fairly stable in lake water in the dark, with

Volatilization of metolachlor from water

Journal of Environmental Science and Health, Part B, 1995
Abstract The volatilization of metolachlor [2‐chloro‐N‐(2‐ethyl‐6‐methylphenyl)‐N‐(2‐methoxy‐l‐methylethyl)acetamide]from water was studied in the laboratory and in an outdoor open‐channel experiment. As expected, volatilization was not significant at temperatures ≤ 25 °C.

The Degradation and Bioactivity of Metolachlor in the Soil

Weed Science, 1986
In bioassays, rice (Oryza sativaL.) recovery from metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide] injury tended to be slower in flooded rice, but was not significantly different from the recovery rate in a nonflooded rice. In soils treated with 1 ppm (w/w) metolachlor and incubated in constant-temperature chambers,

Degradation of Metolachlor in Crude Extract ofAspergillus Flavus

Journal of Environmental Science and Health, Part B, 2004
Crude enzyme from a soil fungus, Aspergillus flavus, was isolated from a field soil following repeated applications of metolachlor [2-Chloro-N-(methoxy-1-methylethyl)-2'-ethyl-6'-methyl acetanilide]. Metolachlor hydrolysis by the crude enzyme extract was determined by enzyme assay.

Microbial dechlorination of the herbicide metolachlor

Journal of Agricultural and Food Chemistry, 1991
The objective of the present study was to examine four microbial strains for their ability to dechlorinate metolachlor, to isolate and identify the formed products, and to determine the mechanism of transformation.

Metolachlor stereoisomers: Enantioseparation, identification and chiral stability

Journal of Chromatography A, 2016
Metolachlor is a chiral herbicide consisting of four stereoisomers, which is typically used as a racemic mixture or is enriched with the herbicidally active 1'S-isomers. Because studies on the enantioselective behavior of phyto-biochemical processes and the environmental fate of metolachlor have become significant, a practical method for analyzing and ...
