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

Nanopartículas de alginato como sistema de liberação para o herbicida clomazone [PDF]

Química Nova, 2010
In this paper, we describe the preparation of alginate nanoparticles as a delivery system for the herbicide clomazone. Two different methods were investigated and characterized by size distribution, zeta potencial, pH and in vitro release.

Herbicide toxicity to Nitrospirillum amazonense: assessing bacterial survival and microbial functionality. [PDF]

Pest Manag Sci
Herbicides elicit a spectrum of responses in Nitrospirillum amazonense, ranging from the stimulation of metabolic functions (biological nitrogen fixation, IAA production) to significant growth inhibition and acute toxicity. Abstract BACKGROUND Herbicides can exert significant toxicity on nontarget organisms, including plant growth‐promoting bacteria ...

Efeito da associação do herbicida clomazone a nanoesferas de alginato/quitosana na sorção em solos [PDF]

Química Nova, 2012
Agrochemicals constitute the class of products most commonly found in water resources. Their high level of concentration is due to the fact that less than 0.1% of pesticides applied to crops reach their target. The present work aims to study the sorption

Influence of Formulation on Mobility of Clomazone in Soil [PDF]

Bulletin of Environmental Contamination and Toxicology, 2016
The mobility of clomazone [2-(2-chlorobenzylo)-4,4-dimetylo-1,2-oxazolidin-3-one] in a loamy sand soil and a sand soil was studied in a soil column under laboratory conditions. Commercial clomazone formulation (Command 480 EC) and clomazone immobilized in an alginate matrix were used for a leaching experiment.
