Availability and Persistence of Imazaquin, Imazethapyr, and Clomazone in Soil
Weed Science, 1989The availability and persistence of imazaquin, imazethapyr, and clomazone were studied in a Cisne silt loam (1.3% organic matter) and a Drummer silty clay loam (5.8% organic matter). Availability of all three herbicides to bioassay species was greater in the Cisne soil than in the Drummer soil.

Clomazone volatilization under varying environmental conditions
Chemosphere, 1996Abstract Velvetleaf ( Abutilon theophrasti Medik.) was used as a bioindicator to examine factors (temperature, soil moisture, soil incorporation) which might influence clomazone {2-[(2-chlorophenyl)methyl] -4,4-dimethyl-3-isoxazolidinone} volatilization.

Crop Response to Fallow Applications of Atrazine and Clomazone
Weed Technology, 1993The response of oat, foxtail millet, proso millet, and sunflower to atrazine and clomazone applied the previous fall was investigated two years in field studies near Akron, CO and Sidney, NE. Foxtail millet biomass, and proso millet and sunflower grain yields were not reduced when these crops were seeded into soil that had been treated the previous ...

Bioaccumulation and Elimination of the Herbicide Clomazone in the Earthworms Eisenia fetida
Bulletin of Environmental Contamination and Toxicology, 2015Acute toxicity, bioaccumulation, and elimination of herbicide clomazone in the earthworm Eisenia fetida were investigated in the different exposure systems. The LC50 values of clomazone on earthworms were 5.6 μg cm(-2) in the contact filter paper test (48 h), 174.9 mg kg(-1) (7 days) and 123.4 mg kg(-1) (14 days) in artificial soil test, respectively ...

Burned rice straw reduces the availability of clomazone to barnyardgrass
Science of The Total Environment, 2008Field 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.

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).

Rice (Oryza sativa) response to clomazone
Weed Science, 1998Experiments 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.

Use of Pistia stratiotes for phytoremediation of water resources contaminated by clomazone
Chemosphere, 2019The Pistia stratiotes L. was tested for phytoremediation potential of the compound clomazone in water. Clomazone is a post-emergent herbicide marketed as Gamit®. Five groups with four samples each were evaluated, a low concentration control (LCC: 37.86 mg L-1), low concentration treatment (LCT: 38.16 mg L-1), high concentration control (HCC: 54.71 mg L-

Effect of clomazone on various market classes of dry beans
Crop Protection, 2007Abstract Tolerance of eight cultivars of dry beans representing eight market classes (black, brown, cranberry, kidney, otebo, pinto, white, and yellow eye beans) to the pre-emergence application of clomazone at the dose of 1116 and 2232 g a.i. ha −1 was studied at Exeter and Ridgetown, Ontario, Canada in 2003 and 2005.

Clomazone measurement by enzyme-linked immunosorbent assay
Journal of Agricultural and Food Chemistry, 1991An 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 ...
