Adsorption and Desorption of Metolachlor and Metolachlor Metabolites in Vegetated Filter Strip and Cultivated Soil

Journal of Environmental Quality, 2004
ABSTRACTPrevious studies have indicated that dissolved‐phase metolachlor [2‐chloro‐N‐(2‐ethyl‐6‐methylphenyl)‐N‐(methoxy‐1‐methylethyl)acetamide] transported in surface runoff is retained by vegetative filter strips to a greater degree than either metolachlor oxanilic acid [2‐[(2‐ethyl‐6‐methylphenyl)(2‐methoxy‐1‐methylethyl)amino]‐2‐oxoacetic acid ...

Environmental Fate of Alachlor and Metolachlor

1989
Decision-makers, scientists, and the interested public should be informed what future research and education is needed if a strong pesticide regulatory program is imposed. Recommendations are intended to highlight research gaps. Some may be of general concern and apply to many pesticides.

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.

Metolachlor and Atrazine in the Great Lakes

Environmental Science & Technology, 2010
Concentrations of atrazine and metolachlor and stereoisomer fractions (SF = herbicidally active/total stereoisomers) of metolachlor were determined in 101 surface water samples collected from the five Laurentian Great Lakes in 2005-2006. Geometric mean (GM) concentrations of atrazine ranged from 5.5 to 61 ng L(-1), decreasing from lakes Ontario ...

Residue, Chemical Placement, And Metolachlor Mobility

Transactions of the ASAE, 1990
ABSTRACT Monolithic soil cores were used to evaluate the impact of tillage and point-of-chemical placement on off-site movement of metolachlor. Nine 254-mm diameter soil cores were removed from an agriculturally productive field site and positioned under a rainfall simulator.

Atrazine and metolachlor degradation in subsoils

Biology and Fertility of Soils, 2001
Degradation of atrazine [2-chloro-4-etylamino-6-isopropylamino-1,3,5-triazine] and metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)-acetamide] in sterile and non-sterile soil samples collected at two different soil depths (0–20 and 80–110 cm) and incubated under aerobic and anaerobic conditions was studied.

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

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

Metolachlor Transport in Surface Runoff

Journal of Environmental Quality, 1990
AbstractIn 1987 metolachlor [2‐chloro‐N‐(2‐ethyl‐6‐methylphenyl)‐N‐(2‐methoxy‐1‐methylethyl) acetamide] was applied to a 5.5‐ha corn field in southern Ontario, Canada, in two separate areas—as a preemergence surface spray with cross‐contour plowing and as a pre‐plant incorporated treatment with contour plowing.
