Photolysis of chlorimuron‐ethyl

Toxicological & Environmental Chemistry, 1997
To examine the photostability of the herbicide chlorimuron‐ethyl (ethyl‐2‐[[[[(4‐methoxy‐6‐chloro‐pyrimidin‐2‐yl)amino]carbonyl]amino]sulfonyl]benzoate) in the field, model experiment with organic solvent was performed. Photolysis of chlorimuron‐ethyl in methanol solution resulted in the formation of seven major and five minor photoproducts, isolated ...

Chlorimuron ethyl metabolism in corn

Pesticide Biochemistry and Physiology, 1991
Abstract [14C]Chlorimuron ethyl was readily absorbed by the roots of young intact corn seedlings and through the cut ends of excised leaves, but it was not readily absorbed by intact leaves. Under the conditions employed, [14C]chlorimuron ethyl was metabolized at a moderate rate in both intact roots and excised leaves (ca.

Effects of Tillage on Chlorimuron Persistence

Weed Science, 1996
Field studies were conducted in Mississippi on a Marietta loam during 1988, 1989, and 1990, and in Tennessee on a Statler loam during 1988 and 1989, to determine effect of tillage on chlorimuron persistence. A corn shoot bioassay was conducted to determine bioavailable chlorimuron in the soil.

Photolysis of chlorimuron‐ethyl in benzene

Toxicological & Environmental Chemistry, 1997
Chlorirauron‐ethyl, a sulfonylurea herbicide was irradiated by ultra violet light from a medium pressure Hg lamp (>290 nm) in benzene solution using a quartz apparatus. Three major and six minor products were identified by spectroscopic methods. These products are formed by cleavage of sulfonylurea bridge, rearrangement, dechlorination etc. The rate of

Reaction of chlorimuron‐ethyl with diazomethane

Toxicological & Environmental Chemistry, 1996
Methylation of chlorimuron‐ethyl with etheral solution of diazomethane gave ethyl‐2‐[[[[(4‐chloro‐6‐methoxy‐2‐pyrimidinyl) N‐methylamino] carbonyl] N‐methylamino] sulfonyl] benzoate (dimethyl derivative of chlorimuron‐ethyl) as the major product along with 4‐chloro‐6‐methoxy‐2‐N‐methylamino pyrimidine, 2‐aminomethyl sulfonyl benzoic acid, ethyl‐2‐[(N ...

Dissipation of Chlorimuron in Southern Soils

Weed Science, 1994
Chlorimuron dissipation as determined by bioavailability in nine soils across the Southern United States was characterized by rapid initial loss followed by a slower dissipation rate following field application of the herbicide in soybean. The rate of bioavailable dissipation varied by year and soil The calculated time for 50% dissipation of ...
