Effect of Chlorimuron and Quizalofop on Fatty Acid Biosynthesis

Weed Science, 1992
Chlorimuron 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, 1998
Field 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.

Biodegradation of Chlorimuron-ethyl by the BacteriumKlebsiella jilinsis2N3

Journal of Environmental Science and Health, Part B, 2010
Enrichment 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

Addition of Nonionic Surfactant to Glyphosate Plus Chlorimuron

Weed Technology, 2004
Field 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 ...

Surfactant-Altered Rates of Chlorimuron and Metsulfuron Photolysis in Sunlight

Weed Science, 1990
Two nonionic surfactants altered photolysis rates of chlorimuron and metsulfuron in aqueous solutions and on glass slides exposed to sunlight. Photolysis of both herbicides followed first-order kinetics over an 8-day exposure period. Chlorimuron half-lives in solution were 5.8, 3.7, and 2.7 days in the presence of no surfactant, oxysorbic, and ...

Isolation and Cultivation Optimization of Chlorimuron-Ethyl Degrading Strains

Advanced Materials Research, 2010
Bacterial 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.

Chlorimuron Dissipation in Water and Soil at 5 and 25 °C

Journal of Agricultural and Food Chemistry, 1997
Chlorimuron, 2-[[[[(4-chloro-6-methoxy-2-pyrimidinyl)amino]carbonyl]amino]sulfonyl]benzoic acid ethyl ester, was added to water (pH 7.5, hardness = 110 mg of CaCO 3 /L) and soil (sandy loam, pH 5.2) to determine the rates of dissipation at 5 and 25 °C.

Application Rate and Timing of Acifluorfen, Bentazon, Chlorimuron, and Imazaquin

Weed Technology, 1992
Data from field studies at Fayetteville, AR, were used to predict the herbicide rate needed to provide 70, 80, or 90% control of a weed based upon weed age. Reduced herbicide rates generally needed to be applied within 6 to 12 d after emergence to control weeds 90%.

Effect of chlorimuron‐ethyl on Bradyrhizobium japonicum and its symbiosis with soybean

Pest Management Science, 2005
AbstractPossible side‐effects of the acetolactate synthase (ALS)‐inhibiting herbicide chlorimuron‐ethyl on Bradyrhizobium japonicum (Kirchner & Jordan) in pure culture and on inoculated soybean plants growing under controlled conditions were investigated.

Photolysis of Aqueous Chlorimuron and Imazaquin in the Presence of Phenolic Acids and Riboflavin

Weed Science, 1993
Laboratory experiments were conducted to determine the effect of three phenolic acids, acetone, and riboflavin on aqueous photolysis of chlorimuron and imazaquin. The phenolic acids investigated were caffeic acid (CA), ferulic acid (FA), andp-coumaric acid (PCA).
