Butachlor, a commonly used herbicide adversely affects the nitrogen fixing capability of Anabaena, an acclaimed nitrogen fixer in the Indian paddy fields. The nitrogen fixation in Anabaena is triggered by the excision of nifD element by xisA gene leading to rearrangement of nifD forming nifHDK operon in the heterocyst of Anabaena sp. PCC7120. Functional elucidation adjudged through in-silico an...

Acetochlor [2-chloro-N-(ethoxymethyl)-N-(2-ethyl-6-methyl-phenyl)-acetamide], alachlor [N-(methoxymethyl)-2-chloro-N-(2, 6-diethyl-phenyl)acetamide], butachlor [N-(butoxymethyl)-2-chloro-N-(2,6-diethyl-phenyl)acetamide], and metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl) acetamide] are pre-emergent herbicides used in the production of agricultural crops. These herb...

Background: The expansion of herbicide used in aquatic ecosystems as well as in terrestrial if is not properly controlled may produce harmful effects on freshwater fisheries. Residue limits of these agricultural chemicals in tropical fishery waters should be established. The aim of this study was to determine the acute toxicity of butachlor and pertilachlor as potential dangerous herbicides to ...

Background: Cirrhinus mrigala, one of the important fish widely consumed in India, was used for karyological observations and to evaluate the toxic effect of butachlor, an extensively used herbicide in rice fields in terms of chromosomal aberration test. Methods: Fishes were collected from “National Fish Seed Farm” Jyotisar with mean body weight of 20-50g. The experimental fishes were kept i...

An experiment was carried out at Regional Research Station, Wadura, SKUASTKashmir during 2012-2013 to evaluate different herbicides in gladiolus. The experiment consisted of eight different herbicides, cultural practices as weed control treatment and unweeded control and were replicated thrice in randomised block design. Among four herbicides i.e atrazine, metribuzin, butachlor and pendimethali...

Four different bacteria capable of degrading butachlor, as well five syntrophic pairs able to break down were isolated from rice paddy soils in Korea. Genetic and phenotypic analyses conducted better understand their characteristics behavior. All single isolates utilize butachlor a sole carbon energy source. Analysis the 16S rRNA sequence showed that related members genus Rhodococcus new type b...

The aim of this study was to evaluate the safety effects of prebiotic isomalto-oligosaccharid on the damage of liver and gill tissues in common carp exposed to lethal concentrations of toxin butachlor. A total of 120 specimens of common carp with an average weight of 6.13±0.31 g were kept. Water physicochemical parameters were measured during the experiment.  LC50 96h for toxin butachlor was ob...
