Interaction of the Herbicide Acifluorfen with Montmorillonite: Formation of Insoluble Fe3+, Al3+, Cu2+, and Ca2+ Complexes

Clays and Clay Minerals, 1991
Analytical, spectroscopic, and X-ray powder diffraction techniques were used to investigate the adsorption of the herbicide sodium acifluorfen (acifluorfen = 5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid) from aqueous solution onto Cu2 ...

Cometabolic degradation of acifluorfen by a mixed microbial culture

Journal of Environmental Science and Health - Part B Pesticides, Food Contaminants, and Agricultural Wastes, 1994
Laboratory experiments were conducted to study the degradation of acifluorfen 5-[2-chloro-4-(trifluoromethyl)-phenoxyl]-2-nitrobenzoic acid by a mixed microbial population. Concentrations of acifluorfen up to 100 mg/l had no inhibitory effect on the growth of microbial culture.

A Non-Metabolic Model of Acifluorfen Activity

Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 1987
The para-nitro substituted diphenyl ether herbicides which cause rapid plant pigment photo- bleaching can be divided into two categories: 1. those that have a photosynthetic requirement for activity (e.g. oxyfluorfen) and 2. those that have no apparent metabolic requirement for activity (e.g. acifluorfen).

Selective Induction of Glutathione S-Transferase Subunits in Wheat Plants Exposed to the Herbicide Acifluorfen

Zeitschrift Fur Naturforschung - Section C Journal of Biosciences, 2000
Exposure to the herbicide acifluorfen resulted in marked increase of glutathione S-transferase (GST) enzyme activity in wheat seedlings, primarily in shoot tissues.

Synthesis of tritiated derivatives of the diphenylether herbicides acifluorfen and acifluorfen methyl

Journal of Labelled Compounds and Radiopharmaceuticals, 1992
AbstractAcifluorfen 1 and acifluorfen methyl 2, two herbicides of the diphenylether family, are inhibitors of protoporphyrinogen oxidases. Two tritiated derivatives of these compounds, namely 3‐[3H]‐5‐[2‐chloro‐4‐(trifluoromethyl)phenoxy]‐2‐nitrobenzoic acid [3H]‐1, and methyl 3‐[3H]‐5‐[2‐chloro‐4‐(trifluoromethyl)phenoxy]‐2‐nitrobenzoic acid [3H]‐2 ...

Photolysis of acifluorfen in aqueous solution

Pesticide Science, 1991
AbstractThe photolysis of acifluorfen, sodium 5‐[2‐chloro‐4‐(trifluoromethyl)‐phenoxy]‐2‐nitrobenzoate (I) in aqueous solution afforded only 2‐chloro‐1‐(4‐nitrophenoxy)‐4‐trifluoromethylbenzene (II) arising from photodecarboxylation. The reaction followed first‐order kinetics, though the photo‐reaction rate was solvent‐dependent.

Characterization of [³H]acifluorfen binding to purified pea etioplasts, and evidence that protoporphyrinogen oxidase specifically binds acifluorfen

European Journal of Biochemistry, 1992
It is now generally accepted that protoporphyrinogen oxidase is the target‐enzyme for diphenylether‐type herbicides. Recent studies [Camadro, J‐M., Matringe, M., Scalla, R. & Labbe, P. (1991) Biochem. J. 277, 17–21] have revealed that in maize, diphenyl ethers competitively inhibit protoporphyrinogen oxidase with respect to its substrate ...

Acifluorfen Tolerance inLycopersicon

Weed Science, 1992
Studies were conducted to determine the mechanism of acifluorfen tolerance within theLycopersicongenus. Absorption of14C-acifluorfen was not correlated with tolerance. There was a negative correlation (r = −0.57) between absorption 24 h after treatment and wax density. No other surface characteristic correlated with absorption.

Mitochondrial involvement in the mode of action of acifluorfen

Pesticide Biochemistry and Physiology, 1984
Abstract The herbicidal action of acifluorfen {5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid} was studied with greened and expanded discs from cotyledons of cucumber ( Cucumis sativus L.). Discs were floated on various treatment solutions for 20 hr in darkness before exposure to 400 μE m −2 sec −1 of white light. Herbicide damage, as
