Studies of clomazone mode of action

Pesticide Biochemistry and Physiology, 2006
Abstract Intact spinach chloroplasts were used to determine if clomazone, 5-OH clomazone, and/or 5-keto clomazone inhibited the chloroplastic isoprenoid pathway. When isopentenyl pyrophosphate was used as a precursor, neither clomazone nor the clomazone metabolites (5-OH clomazone and 5-keto clomazone) inhibited the formation of products separated by

Clomazone dissipation in four Tasmanian topsoils

Weed Science, 2002
Abstract Clomazone dissipation was examined in four soils in field experiments. Field half-lives were 6 to 59 d (average of four field sites was 35 d) for ferrosol (clay loam), kurosol (loamy sand), sodosol (silt loam), and vertosol (light clay). The Hoerl equation provided a better fit to the measured field concentration at all four sites than did a ...

Metabolism of clomazone herbicide in soybean

Journal of Agricultural and Food Chemistry, 1992
The metabolism of 2-[(2-chlorophenyl) methyl]-4,4-dimethyl-3-isoxazolidinone (clomazone) was studied in soybean plants grown in the greenhouse using 14C-radiolabeled clomazone at 1.1 and 2.2 kg of ai/ha. Isolation and identification of clomazone metabolites from soybean plants at 30 and 60 days after treatment indicated that the major metabolic ...

Clomazone influence soil microbial community and soil nitrogen cycling

Science of The Total Environment, 2018
We designed an indoor mesocosm experiment to investigate the long-term effects of exposure to clomazone, a widely used herbicide, on soil microbial communities and their nitrogen (N) cycling functions. Clomazone was applied to two typical soils from China at three concentrations: 0.8 (the recommended dosage), 8 and 80 mg kg-1 soil dry weight, and the ...

Biochemical effects of clomazone herbicide on piava (Leporinus obtusidens)

Chemosphere, 2008
This study aims to verify the effects of the clomazone concentration used in rice fields on acetylcholinesterase (AChE), thiobarbituric acid reactive substances (TBARS), protein carbonyl and catalase activity in tissues of piava (Leporinus obtusidens).

Clomazone measurement by enzyme-linked immunosorbent assay

Journal of Agricultural and Food Chemistry, 1991
An indirect, competitive, enzyme-linked immunosorbent assay (ELISA) was developed for the measurement, in soil, of clomazone [FMC 57020, 2-[(2-chlorophenyl)methyl]-4,4-dimethyl-3-isoxazolidinone], the active ingredient of Command herbicide. The p-aminophenyl analogue of clomazone was used to prepare a bovine serum albumin conjugate for immunization of ...

Microbial Degradation of Clomazone under Simulated California Rice Field Conditions

Journal of Agricultural and Food Chemistry, 2010
Clomazone (trade names Cerano and Command) is a popular herbicide used on California rice fields to control aquatic weeds. Its physicochemical characteristics indicate that it will persist primarily in the water column, where microbial degradation may drive its environmental fate. The objectives were to determine microbial degradation rates and compare

Rice (Oryza sativa) response to clomazone

Weed Science, 1998
Experiments were conducted in 1993 and 1994 to determine if seed treated with disulfoton at 3, 6, or 12 g ai kg−1 reduced bleaching of rice foliage caused by clomazone applied delayed preemergence at 0.56, 1.1, 1.7, or 2.2 kg ai ha−1 on silt loam and silty clay soils. Clomazone injured rice more on silt loam soil than on silty clay soil.

Burned rice straw reduces the availability of clomazone to barnyardgrass

Science of The Total Environment, 2008
Field burning of crop residue is a common post-harvest practice to dispose of these agricultural by-products and for land clearing. Burned crop residues may effectively adsorb pesticides and thus influence their bioavailability in agricultural soils. The adsorption of clomazone by a soil amended with a burned rice straw (BRS) was measured.
