Interactions of Diphenylether Herbicides with Chlorimuron and Imazaquin
Weed Technology, 1992Field experiment were conducted to determine interactions of chlorimuron or imazaquin with fomesafen, lactofen, or acifluorfen on three-leaf and eight-leaf common cocklebur, hemp sesbania, pitted morningglory, and prickly sida. Antagonism was the most common interaction with common cocklebur, and was most severe with chlorimuron combined with fomesafen

Studies on photodegradation of chlorimuron-ethyl in soil
Pesticide Science, 1997Photolysis of chlorimuron-ethyl was studied on a soil surface under sunlight and UV light. Eight photoproducts were isolated and characterised by spectroscopic methods. Major photoproducts are formed by cleavage of the sulfonylurea bridge and minor products are formed via dechlorination, hydrolysis and cyclisation.

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.

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 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 ...

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 ...

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 ...

Isolation and Cultivation Optimization of Chlorimuron-Ethyl Degrading Strains
Advanced Materials Research, 2010Bacterial strains with chlorimuron-ethyl degrading ability were isolated for bioremediation of contaminated soil. Six strains were obtained from chlorimuron-ethyl contaminated soil by enrichment cultivation. HPLC analysis indicated that two strains (A4 and A5) demonstrated high degradation efficiency than other strains.

Isolation of chlorimuron-ethyl degrading strains from contaminated soil
2011 International Symposium on Water Resource and Environmental Protection, 2011Six bacterial strains with chlorimuron-ethyl degrading ability were isolated from chlorimuron-ethyl contaminated soil by enrichment cultivation. The degradation of chlorimuron-ethyl was analyzed using high performance liquid chromatography (HPLC).

Alcoolyse et hydrolyse chimique du chlorimuron éthyle
Weed Research, 1995Summary: RésuméLa coupure de la fonction urée est seule observée au cours de 1'alcoolyse (méthanol ou éthanol) et de l'hydrolyse (pH8) du chlorimuron éthyle à 30°C ou 50°C. La pyrimidinamine est quantitativement formée dans tous les cas accompagnée des carbamates correspondants (alcoolyse) ou du phénylsulfonamide (hydrolyse) quise cyclise facilement en
