Impact of acetochlor on ammonia-oxidizing bacteria in microcosm soils
Journal of Environmental Sciences, 2008Acetochlor is an increasingly used herbicide on corn in North China. Currently, the effect of acetochlor on soil ammonia-oxidizing bacteria (AOB) communities is not well documented. Here, we studied the diversity and community composition of AOB in soil amended with three concentrations of acetochlor (50, 150, 250 mg/kg) and the control (0 mg ...

Absorption and distribution of flurazole and acetochlor in grain sorghum
Pesticide Biochemistry and Physiology, 1986Abstract The site of uptake, absorption, and distribution of a safener, flurazole [2-chloro-4-(trifluoromethyl)-5-thiazolecarboxylic acid, (phenylmethyl ester)], and a herbicide, acetochlor [2-chloro- N -(ethoxymethyl)-6′-ethyl- O -acetoluidide], in grain sorghum [ Sorghum bicolor (L.) Moench “G-522 DR”] were investigated in laboratory and growth ...

Degradation and detoxification of acetochlor in soils treated by organic and thiosulfate amendments
Chemosphere, 2007This work investigated the degradation and detoxification of acetochlor in a soil amended with an organic fertilizer or sodium thiosulfate (STS). Over an incubation period of 28 d, the residual acetochlor was measured, soil dehydrogenase activity was determined, and major degradates were identified.

Acetochlor Persistence in Surface and Subsurface Soil Samples
Water, Air, & Soil Pollution, 2013Although degradation data for herbicides are essential in understanding their potential to be contaminants and are indispensable inputs in computer-based modeling of their fate in environment, most available data only concern surface soils. Soil samples, collected at two depths from four representative sites of a 31.4-ha field located in Blue Earth ...

Effect of soil and sediment composition on acetochlor sorption and desorption
Environmental Science and Pollution Research, 2009Herbicide fate and its transport in soils and sediments greatly depend upon sorption-desorption processes. Quantitative determination of herbicide sorption-desorption is therefore essential for both the understanding of transport and the sorption equilibrium in the soil/sediment-water system; and it is also an important parameter for predicting ...

Evaluation of the mutagenicity of acetochlor to male rat germ cells
Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 1997Male rat dominant lethal (DL) assays conducted on the herbicide acetochlor are described. Single dose studies conducted at the maximum tolerated dose (MTD, < or = 1000 mg/kg) produced no effects on any of the DL assay parameters at any of the ten weekly sampling periods. It is concluded that acetochlor is non-mutagenic to rat germ cells. Due to initial

Thermal investigation of acetochlor adsorption on inorganic- and organic-modified montmorillonite
Journal of Thermal Analysis and Calorimetry, 2015Results presented in this paper are pioneering attempt toward better understanding of the thermal stability of acetochlor sorption in inorganic and organic montmorillonites. Changes in surface properties of acetochlor adsorbed on montmorillonites and montmorillonites modified with hexadecyltrimethylammonium bromide have been investigated by ...

Photosynthesis and growth responses of grapevine to acetochlor and fluoroglycofen
Pesticide Biochemistry and Physiology, 2012Abstract Acetochlor and fluoroglycofen are herbicides used in vineyards to eradicate weeds. This present study characterized the effects of these chemicals on photosynthetic characteristics and the antioxidant enzyme system in non-target grape leaves.

Current insights into environmental acetochlor toxicity and remediation strategies
Environmental Geochemistry and HealthAcetochlor is a selective pre-emergent herbicide that is widely used to control annual grass and broadleaf weeds. However, due to its stable chemical structure, only a small portion of acetochlor exerts herbicidal activity in agricultural applications, while most of the excess remains on the surfaces of plants or enters ecosystems, such as soil and ...

An incubation test was conducted with mollisol applied with recommended amount of acetochlor under the conditions of sterilization, microbial inhibitor addition, and non-sterilization. During incubation, the residual amount of acetochlor and the dynamics of soil phospholipid fatty acids (PLFAs) were determined to study the relative contribution of soil
