Enantiomeric characterization of herbicide lactofen: Enantioseparation, absolute configuration assignment and enantioselective activity and toxicity [PDF]
Chemosphere, 2018 Chiral herbicides consist of two or more enantiomers, which usually differ in their biological properties and behave enantioselectively in biochemical process. Scant studies have been published in the past decades to characterize the enantiomers of herbicide lactofen.

Lactofen – Electrochemical Sensing and Interaction with dsDNA [PDF]
Electroanalysis, 2017 AbstractThe electrochemical reduction of lactofen (LCT) at the glassy carbon (GCE) and silver amalgam film electrode (AMFE) is investigatedin detail by the means of square wave voltammetry (SWV), square wave stripping voltammetry (SWSV) and cyclic voltammetry. The influence of various factors such as supporting electrolyte composition and SW parameters

The diphenyl ether herbicide lactofen is commonly used to control broadleaf weeds. Once released into the environment, this herbicide is subject to microbial reactions. This study describes the biotransformation of lactofen by Brevundimonas sp. LY-2 isolated from enrichment cultures inoculated with soil sample. This strain degraded about 80% of 50 mg L(

Enantioselectivity of chiral compounds is receiving growing concern. Lactofen, a chiral herbicide widely used in field crops and vegetables to control broadleaf weeds, is still sold as racemate. In this work, the herbicidal activity and metabolism behavior of lactofen were investigated on an enantiomeric level.

Stereoselective Toxicity and Metabolism of Lactofen in Primary Hepatocytes From Rat
Chirality, 2013ABSTRACTThe stereoselective metabolism of lactofen in primary rat hepatocytes was studied using a chiral high‐performance liquid chromatographic (HPLC) method. Rac‐lactofen and its two enantiomers, S‐(+)‐ and R‐(−)‐lactofen, as well as two of its major metabolites, acifluorfen, S‐(+)‐ and R‐(−)‐desethyl lactofen, were used as substrates,.

Influence of Soil Properties on the Enantioselective Dissipation of the Herbicide Lactofen in Soils
Journal of Agricultural and Food Chemistry, 2009A scheme was developed to elucidate the dissipation behaviors of the two enantiomers of the herbicide lactofen in soils using a normal-phase high-performance liquid chromatograph (HPLC) with UV detector and a column with a cellulose-tri-(3,5-dimethylphenylcarbamate)-based chiral stationary phase (CDMPC-CSP).

Effects of Salinity on Herbicide Lactofen Residues in Soil
Water, Air, and Soil Pollution, 2017Soil salinization is an increasing problem in agricultural soils on a worldwide scale. To assess the effects of salinity on the fate of herbicide lactofen in soil, laboratory degradation experiments were performed using soil with and without additional salinity.

Enantioselective toxicity of lactofen and its metabolites in Scenedesmus obliquus
Algal Research, 2015Abstract In this study, the acute toxicity of lactofen and its two metabolites desethyl lactofen and acifluorfen was determined in the aquatic algae Scenedesmus obliquus . After exposure for 96 h, the EC 50 values for S-(+)-, rac-, and R-(−)-lactofen were 0.896, 0.784, and 0.649 μg/L, respectively; the EC 50 values for S-(+)-, rac-, and R ...

Lactofen Systems for Broadleaf Weed Control in Peanuts (Arachis hypogaea) [PDF]
Weed Technology, 1990 Weed management systems using a chloroacetamide herbicide applied preplant incorporated (PPI) and at cracking (AC) plus lactofen applied AC and early postemergence (POST) controlled at least 98% of common lambsquarters. Similar systems using a chloroacetamide herbicide applied PPI and early POST plus lactofen applied early POST and postemergence (POST)

Soil Amendment: A Technique for Soil Remediation of Lactofen
Bulletin of Environmental Contamination and Toxicology, 2007Lactofen, a member of the diphenyl ether chemical family, shows great potential for the control of broadleaf weeds associated with leguminous crops. It presents a high degree of selectivity when applied post-emergence to soybean and peanut crops. This paper presents the persistence of lactofen under a soybean crop under various conditions, including ...
