Quinclorac Absorption and Translocation Characteristics in Quinclorac- and Propanil-resistant and -susceptible Barnyardgrass (Echinochloa Crus-galli) Biotypes

Weed Technology, 2007
Studies were initiated to evaluate absorption, translocation, and distribution of 14C-quinclorac in propanil- and quinclorac-resistant (R-BYG) and -susceptible (S-BYG) barnyardgrass. No differential absorption of 14C-quinclorac was observed between R-BYG and S-BYG, but more 14C remained in the treated leaf of S-BYG (57% of total absorbed) compared with

Mechanism of Action and Selectivity of Quinclorac in Grass Roots

Pesticide Biochemistry and Physiology, 1997
Abstract The mechanism of action and selectivity of quinclorac (3,7-dichloroquinolinecarboxylic acid) were investigated by comparing the inhibitory effect of the herbicide on [ 1 4 C]glucose incorporation into the root cell walls of susceptible and resistant grasses and by measuring root accumulation of [ 1 4 C]quinclorac.

Binding interaction of quinclorac with bovine serum albumin: A biophysical study

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2009
Quinclorac (QUC) is a new class of highly selective auxin herbicides. The interaction between QUC and bovine serum albumin (BSA) was investigated by fluorescence spectroscopy, synchronous fluorescence, three-dimensional fluorescence, CD spectroscopy and UV-vis absorption spectroscopy under simulative physiological condition.

Analysis of quinclorac and quinclorac methyl ester in canola from the 2015 harvest using QuEChERS with liquid chromatography polarity-switching tandem mass spectrometry

Food Additives & Contaminants: Part A, 2016
A method using QuEChERS sample preparation with liquid chromatography polarity-switching tandem mass spectrometry was developed and validated for the analysis of quinclorac and its degradation product quinclorac methyl ester in canola seed. The method was used to analyse canola treated with quinclorac, harvest sample composites and samples of canola ...

Effects of low molecular weight organic acids on adsorption of quinclorac by sepiolite

Environmental Science and Pollution Research, 2020
The effects of low molecular weight organic acids (LMWOAs) on the adsorption of quinclorac by sepiolite were investigated using laboratory batch technique. Experiments were conducted with two natural sepiolite samples with different crystal structures and chemical compositions and high-purity sepiolite.

Hybrid Bluegrass Tolerance to Postemergence Applications of Mesotrione and Quinclorac

Weed Technology, 2007
New hybrid bluegrass cultivars have been bred for increased heat and drought tolerance compared with traditional Kentucky bluegrass cultivars. Research was conducted to evaluate hybrid bluegrass tolerance and smooth crabgrass and goosegrass control with mesotrione and quinclorac during seeded establishment. Mesotrione applied as a single application 14,

Involvement of antioxidant capacity in quinclorac tolerance in Eleusine indica

Environmental and Experimental Botany, 2011
Abstract The relationship between quinclorac (3,7-dichloro-8-quinolinecarboxylic acid) tolerance and scavenging capacity of reactive oxygen species (ROS) in Eleusine indica was investigated to understand the tolerance mechanisms of E. indica to the herbicide. E.

Quinclorac resistance: a concerted hormonal and enzymatic effort in Echinochloa phyllopogon

Pest Management Science, 2011
AbstractBACKGROUND: Quinclorac (3,7‐dichloro‐quinoline‐carboxylic acid) is a selective herbicide widely used to control annual grasses and certain broadleaf weeds. Echinochloa phyllopogon (Stapf) Koss. is the most noxious grass weed in California rice fields and has evolved resistance to multiple herbicides with different modes of action.

Rapid green synthesis of gold nanocatalyst for high-efficiency degradation of quinclorac

Journal of Hazardous Materials, 2017
Porous chemical pretreated Saccharomyces cerevisiae was used as support, stabilizer, and reducing agent for the rapid green synthesis of gold nanocatalyst. Au nanoparticles (Au NPs) were generated through in-situ reduction of the absorbed Au(III) by the reductive functional groups of mannoproteins in yeast cell wall.
