Sorption and Mobility of Chlorimuron in Alabama Soils
Weed Science, 1989Soil thin-layer chromatography and a soil solution technique were used to evaluate chlorimuron adsorption and mobility in five Alabama soils. The order of adsorption was atrazine > metribuzin > chlorimuron; mobility was chlorimuron > metribuzin > atrazine.

Phototransformation of Chlorimuron-ethyl in Aqueous Solution
Journal of Agricultural and Food Chemistry, 1996Chlorimuron-ethyl is relatively stable in water buffered to pH 7.0 and 9.0, but hydrolyzes readily (half-life, 14 d) in water buffered to pH 4.0. In addition, chlorimuron-ethyl photodegrades rapidly and extensively in aqueous solution. The predominant photoproducts are 4-methoxy-6-chloro-2-aminopyrimidine, ethyl 2-aminosulfonylbenzoate, N-(4-methoxy-6 ...

Effect of Moisture on Chlorimuron Degradation in Soil
Weed Science, 1990The overall degradation of chlorimuron was very similar at −0.1 and −1.5 MPa and slightly less in air-dry soil. Degradation rates increased with increasing temperature. The primary 14C-labeled compounds observed in moist-soil extracts were desmethyl chlorimuron and saccharin, while the primary 14C-labeled compound observed in air-dry soil extracts was ...

Phototransformation of chlorimuron-ethyl on leaf surface
Toxicological & Environmental Chemistry, 2007Chlorimuron-ethyl, a post-emergent herbicide selectively used in soybean and maize, degrades mainly through chemical hydrolysis. Photolysis has also an important role in the degradation of this compound. Phototransformation of chlorimuron-ethyl takes place through the cleavage of the sulfonylurea bridge, dechlorination, de-esterification and ...

Efficacy of chlorimuron for controlling weeds in soybean
Indian Journal of Weed Science, 2016The field was infested with monocot weeds like Echinochloa colona, Cyperus iria whereas dicot weeds Alternanthera philoxiroides, Eclipta alba, Commelina benghalensis and Phyllanthus niruri were less dominant in soybean. The application of Chlorimuron-ethyl 24 g/ha as early post-emergence along with mechanical weeding was most effective in paralyzing ...

Adsorption-Desorption Characteristics of Chlorimuron-Ethyl in Soils
Agricultural Sciences in China, 2007The adsorption-desorption characteristics of chlorimuron-ethyl in soils were investigated to provide the basic data for evaluating the safety in field and the risk to water resource. The adsorption-desorption experiment was conducted by the batch equilibration and HPLC techniques; furthermore, data were analyzed with 5 mathematic models to describe the

Effect of Chlorimuron and Quizalofop on Fatty Acid Biosynthesis
Weed Science, 1992Chlorimuron antagonized the activity of quizalofop on broadleaf signalgrass when applied in greenhouse studies as a postemergence tank mix. In vitro leaf disc assays utilizing14C-acetate or14C-pyruvate as substrates were conducted to ascertain the effect of clorimuron and quizalofop on fatty acid biosynthesis and to determine if antagonism between the ...

Interaction of glyphosate with chlorimuron, fomesafen, imazethapyr, and sulfentrazone
Weed Science, 1998Field experiments were conducted on eight weed species to determine if chlorimuron, fomesafen, imazethapyr, or sulfentrazone at two rates (labeled and one-half the labeled rate) were complementary tank mixtures with glyphosate at 210 and 420 g ai ha−1.

Addition of Nonionic Surfactant to Glyphosate Plus Chlorimuron
Weed Technology, 2004Field studies were conducted in South Carolina and Georgia to evaluate weed control and soybean tolerance and yield after nonionic surfactant addition to combinations of chlorimuron plus an adjuvant-containing glyphosate formulation. Treatments included glyphosate alone, at 420 or 840 g ae/ha, or in combination with 6 or 9 g ai/ha chlorimuron and all ...

Biodegradation of Chlorimuron-ethyl by the BacteriumKlebsiella jilinsis2N3
Journal of Environmental Science and Health, Part B, 2010Enrichment culturing of sludge taken from an industrial wastewater treatment pond led to the identification of a bacterium (Klebsiella jilinsis H. Zhang) that degrades chlorimuron-ethyl with high efficiency. Klebsiella jilinsis strain 2N3 grows with chlorimuron-ethyl as the sole nitrogen source at the optimal temperature range of 30-35 degrees C and pH
