Metabolism of twelve herbicides by Streptomyces

Biodegradation, 1996
Experiments were conducted to assess the ability of Streptomyces (strain PS1/5) to metabolize twelve herbicides representing several different classes including: acetanilides, triazines, ureas, uracils, and imidazoles. Incubations in aqueous culture with dextrin as carbon source and either ammonium or Casamino acids as nitrogen source resulted in ...

Enhanced Herbicide Metabolism and Target Site Mutation Enabled the Multiple Resistance to Cyhalofop-butyl, Florpyrauxifen-benzyl, and Penoxsulam in Echinochloa crus-galli.

Journal of Agricultural and Food Chemistry
This study investigated the multiple herbicide resistance (MHR) mechanism of one Echinochloa crus-galli population that was resistant to florpyrauxifen-benzyl (FPB), cyhalofop-butyl (CHB), and penoxsulam (PEX).

Comparative aspects of herbicide metabolism

Xenobiotica, 1986
Herbicides are the economically most important group of pesticides, and such activity occurs in a wide range of chemical structural classes. Studies of the metabolism of herbicides involve a great number of organisms and test systems to provide information of value for assessing the nature of potential residues in human foods of plant and animal origin,

Herbicide safeners and glutathione metabolism

Physiologia Plantarum, 1994
Herbicide safeners are chemicals which protect crop plants from injury by certain herbicides, without affecting weed control efficacy of the herbicides. The protective mechanism of herbicide safeners has not yet been fully elucidated, but there is increasing evidence that safeners act by selectively enhancing herbicide detoxification in crop plants.

Two Cytochrome P450s, CYP709B1 and CYP704C1, Play Essential Roles in Metabolism-Based Multiple Herbicide Resistance in American Sloughgrass (Beckmannia syzigachne (Steud.) Fernald).

Journal of Agricultural and Food Chemistry
This study confirmed a field population of American sloughgrass (Beckmannia syzigachne (Steud.) Fernald) that developed simultaneously high levels of resistance (resistance index >10) to three divergent modes of action herbicides: fenoxaprop-P-ethyl ...

THE METABOLISM OF HERBICIDES*

Weed Research, 1964
Summary. A knowledge of the metabolism of herbicides within plants is of importance in a number of ways. Thus, whilst governmental control of the toxicity of potential herbicides is being exercised by fixing acceptable levels of residues, information may also be required an the toxicity of their possible metabolites.

Metabolism of clomazone herbicide in soybean

Journal of Agricultural and Food Chemistry, 1992
The metabolism of 2-[(2-chlorophenyl) methyl]-4,4-dimethyl-3-isoxazolidinone (clomazone) was studied in soybean plants grown in the greenhouse using 14C-radiolabeled clomazone at 1.1 and 2.2 kg of ai/ha. Isolation and identification of clomazone metabolites from soybean plants at 30 and 60 days after treatment indicated that the major metabolic ...

Metabolism-based herbicide resistance: regulationby safeners

Weed Science, 2004
Abstract Safeners are chemical agents that reduce the phytotoxicity of herbicides to crop plants by a physiological or molecular mechanism, without compromising weed control efficacy. Commercialized safeners are used for the protection of large-seeded grass crops, such as corn, grain sorghum, and wet-sown rice, against preplant-incorporated or ...

Cytochrome P450 Endowed Herbicide Metabolism

1997
Metabolism is a key component of herbicide efficiency, selectivity, and in the appearance of resistance. In many cases, oxygen transfer is the first, obligate step in the biotransformation process. These reactions are both slow and irreversible. Therefore, they determine to a large part the kinetics of elimination of the active compound (or its ...
