Clomazone dissipation in four Tasmanian topsoils
Weed Science, 2002Abstract 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, 1992The 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 ...

Agronomy
A bioassay study was conducted to determine the differences in the sensitivity of selected crops to simulated clomazone residues (nine concentrations were used ranging from 5.625 to 1440 μg a.i./kg soil).

Investigation of clomazone-tolerance mechanism in a long-grain cultivar of rice.
Pest Management Science, 2021BACKGROUND Clomazone is a potent herbicide for controlling weeds that have evolved resistance to other herbicides due to its unique mode of action. Clomazone is used in rice cultivation, but is limited to long-grain cultivars because other cultivars are ...

Application of clomazone and oxyfluorfen herbicide mixture and its effect on weed growth
IOP Conference Series: Earth and EnvironmentThis research aims to determine the growth of weeds due to the application of a mixture of clomazone and oxyfluorfen herbicides. The experimental design was a Randomized Completely Block Design. The treatments were: without herbicide (control), 3.125L/ha

Clomazone influence soil microbial community and soil nitrogen cycling
Science of The Total Environment, 2018We 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, 2008This 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).

Interactions of clomazone plus pendimethalin mixed with propanil in rice
Weed technology, 2021A study was conducted at the Louisiana State University Agricultural Center's H. Rouse Caffey Rice Research Station in 2017 and 2018 to evaluate the interaction between a prepackage mixture of clomazone plus pendimethalin applied at 0, 760, 1,145, or 1 ...
