Mechanism of clomazone resistance in Leptochloa fusca spp. fasicularis to clomazone

Pesticide Biochemistry and Physiology, 2020
Bearded sprangletop (Leptochloa fusca spp. fasicularis) is a problematic weed in California rice (Oryza sativa) production. Historically, bearded sprangletop is controlled with clomazone in California rice fields. The continuous use of clomazone and lack of crop rotation in rice fields resulted in resistance to clomazone in several bearded sprangletop.

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

The behavior of clomazone in the soil environment

Pest Management Science, 2009
AbstractBACKGROUND: Clomazone is a herbicide used to control broadleaf weeds and grasses. Clomazone use in agriculturally important crops and forests for weed control has increased and is a potential water contaminant given its high water solubility (1100 µg mL−1).

Clomazone Dissipation in Two Montana Soils

Weed Technology, 1989
Clomazone is effective as a chemical fallow herbicide; however, its soil residual properties in the Northern Great Plains are unknown. Clomazone was applied to soil at 0.6, 1.1, and 2.2 kg ai/ha at two locations in Montana in the spring of 1986. Soil samples were taken at each location at monthly intervals for 6 months. Residual levels of the herbicide

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.

Weed Control with Clomazone Alone and with Other Herbicides

Weed Technology, 1989
The weed control spectrum of clomazone, the influence of clomazone on the performance of other herbicides, and the performance of tank mixtures containing clomazone were evaluated from 1985 through 1987. Clomazone applied preemergence at 280 g ai/ha controlled 90 to 100% of barnyardgrass, giant foxtail, goosegrass, large crabgrass, seedling ...

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 ...

Bioaccumulation and Elimination of the Herbicide Clomazone in the Earthworms Eisenia fetida

Bulletin of Environmental Contamination and Toxicology, 2015
Acute 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 ...
