Butachlor Sorption in Organically Rich Soil Particles

Soil Science Society of America Journal, 2010
The herbicide butachlor [ N ‐(butoxymethyl)‐2‐chloro‐ N ‐(2,6‐diethylphenyl)acetamide] is a pre‐emergence herbicide belonging to the chloroacetanilide group used widely to control grasses in Asian countries.

Study on Leaching Transfer of Butachlor in Black Soil

2010 International Conference on E-Product E-Service and E-Entertainment, 2010
Leaching transfer of herbicides was considered as the main control factor of the transfer conversion of pesticides in the soil-water environment. Using Black soil column, we studied the leaching transfer of Butachlor in Black soil. The experiment results showed that leaching amount of Butachlor and the depth of the highest value of butachlor content ...

Exposure to Oxadiazon-Butachlor causes cardiac toxicity in zebrafish embryos

Environmental Pollution, 2020
Oxadiazon-Butachlor (OB) is a widely used herbicide for controlling most annual weeds in rice fields. However, its potential toxicity in aquatic organisms has not been evaluated so far. We used the zebrafish embryo model to assess the toxicity of OB, and found that it affected early cardiac development and caused extensive cardiac damage ...

[The transferability of acetochlor and butachlor in soil].

Huan jing ke xue= Huanjing kexue, 2002
The transferability of acetochlor and butachlor in soil was studied by soil thin layer chromatography. Acetochlor and butachlor were dropped on the glass plate and spreaded soil on the glass plate was collected per 2 cm, then acetochlor and butachlor were analyzed quantitatively by HPlC. When river water was as the spread solution, Rf(relative flow) of

Characterization of a Novel Butachlor Biodegradation Pathway and Cloning of the Debutoxylase (Dbo) Gene Responsible for Debutoxylation of Butachlor in Bacillus sp. hys-1

Journal of Agricultural and Food Chemistry, 2015
Bacillus sp. strain hys-1, which was isolated from active sludge, could degrade >90% butachlor at a concentration of 100 mg/L within 7 days. The present work revealed that strain hys-1 could mineralize butachlor via the following pathway: butachlor was initially metabolized to 2-chloro-N-(2,6-diethylphenyl)-N-methylacetamide by debutoxylation and then ...

Phylogenetic changes in soil microbial and diazotrophic diversity with application of butachlor

Journal of Environmental Science and Health, Part B, 2013
We investigated changes in population and taxonomic distribution of cultivable bacteria and diazotrophs with butachlor application in rice paddy soils. Population changes were measured by the traditional plate-count method, and taxonomic distribution was studied by 16S rDNA sequencing, then maximum parsimony phylogenic analysis with bootstrapping (1 ...

Photodegradation of the Herbicides Butachlor and Ronstar Using Natural Sunlight and Diethylamine

Bulletin of Environmental Contamination and Toxicology, 2000
Deterioration of water quality by pesticide residues in rivers has raised environmental safety concerns. Butachlor and ronstar are the two most widely used herbicides in Taiwan. Due to their relatively high stability and retardation factors, butachlor and ronstar were persistent environmental pollutants in waters (Widmer and Spalding, 1995, 1996 ...

Butachlor-induced acute toxic hepatitis.

Indian journal of gastroenterology : official journal of the Indian Society of Gastroenterology, 2007
Butachlor is a highly effective herbicidal substance widely used by farmers. We report a 60-year-old man with exfoliative dermatitis, jaundice, increase in liver enzymes and eosinophilia one day after accidental dermal exposure to butachlor toxin. The diagnostic workup showed no other cause and liver histology was consistent with substance-induced ...

An Analytical Method for the Simultaneous Determination of Butachlor and Benoxacor in Wheat and Soil

Journal of Agricultural and Food Chemistry, 2005
Butachlor is a chloroacetanilide herbicide successfully employed in weeding some important crops, and benoxacor is a safening compound able to induce the enzymatic mechanism of chloroacetanilide detoxification in plants. A practical method for a simultaneous detection of butachlor and benoxacor residues in wheat and in soil is described.

Effect of butachlor on microbial soil populations in rice fields

Toxicological & Environmental Chemistry, 1997
Effect of butachlor on soil populations of bacteria, fungi and actinomycetes following application of 1.5 kg a.i.ha‐1 to rice fields were evaluated up to 30 days. Except for a slight initial suppressing effect, butachlor stimulated the microbial activity of rice rhizosphere soil.
