Controlled Release of Herbicide Acetochlor from Clay/Carboxylmethylcellulose Gel Formulations

Journal of Agricultural and Food Chemistry, 2008
Controlled-release formulations of the herbicide acetochlor were prepared by using carboxylmethylcellulose (CMC) gel and different types of clay, which were obtained by acid activation, pillared with metal hydroxides, or saturated with organic cations. The effect of formulation parameters (amount and type of clay used, cross-linking time, and drying of

Current insights into environmental acetochlor toxicity and remediation strategies

Environmental Geochemistry and Health
Acetochlor 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 ...

Development of the Piezoelectric Biosensor for Acetochlor Detection

Analytical Letters, 2003
The piezoelectric immunosensor for the determination of acetochlor was developed. The surface of gold electrodes of piezoelectric quartz crystals was modified by self-assembled thiolayers using either 4-aminothiophenol or dithiobis(succinimidyl propionate).

Soil transformation of acetochlor via glutathione conjugation

Pesticide Biochemistry and Physiology, 1991
Abstract Acetochlor and acetochlor S -glutathione conjugate were degraded in soil with respective half-lives of 7 days and 30 min to a similar distribution of identical metabolites. Degradation of acetochlor-glutathione conjugate appears to be initiated by γ-glutamyl transpeptidase, and the addition of γ-glutamyl transpeptidase inhibitors ...

Impact of acetochlor on ammonia-oxidizing bacteria in microcosm soils

Journal of Environmental Sciences, 2008
Acetochlor 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 ...

Acetochlor Persistence in Surface and Subsurface Soil Samples

Water, Air, & Soil Pollution, 2013
Although 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 ...

Photochemical degradation of acetochlor.

Acta biologica Hungarica, 1995
Photochemical degradation of acetochlor--2-chloro-N-(ethoxymethyl)-N-(2-ethyl-6-methyl-phenyl)- acetamid--was studied at ambient temperature. The herbicide was irradiated by UV-light in methanol and water-methanol solvent mixture. It was found that the photodecomposition of acetochlor obeys first order kinetics under the condition of photolysis.

Fluridone and acetochlor cause unacceptable injury to pumpkin

Weed Technology, 2019
AbstractResidual herbicides are routinely applied to control troublesome weeds in pumpkin production. Fluridone and acetochlor, Groups 12 and 15 herbicides, respectively, provide broad-spectrum PRE weed control. Field research was conducted in Virginia and New Jersey to evaluate pumpkin tolerance and weed control to PRE herbicides. Treatments consisted

Thyroid endocrine disruption of acetochlor on zebrafish (Danio rerio) larvae

Journal of Applied Toxicology, 2015
AbstractThe herbicide acetochlor is widely used and detected in the environment and biota, and has been suspected to disrupt the thyroid endocrine system, but underlying mechanisms have not yet been clarified. In the present study, zebrafish larvae (7 days post‐fertilization) were exposed to a series concentration of acetochlor (0, 1, 3, 10, 30, 100 ...

[Microbial degradation of acetochlor in mollisol and the effects of acetochlor on the characteristics of soil phospholipid fatty acids].

Ying yong sheng tai xue bao = The journal of applied ecology, 2009
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
