Electrochemical reduction of metamitron

Journal of Electroanalytical Chemistry, 1998
Metamitron (I) (4-amino-3-methyl-6-phenyl-1,2,4-triazin-5(4H)-one) is a herbicide which is reduced electrochemically in two 2-e− steps. Reduction in the first step involves the protonated form of the 1,6-azomethine bond, while the second step involves the protonated form of the 2,3-azomethine bond. The 1,6-bond is reduced at potentials ca.

Photochemical reactions of metamitron

Chemosphere, 1997
Abstract Photochemical reactions of metamitron (a 4-amino substituted as-triazin-5(4H)-one) were investigated including UV- and phosphorescence spectroscopy, determination of quantum yields, comparison with measurements in sunlight and products found.

Polarographic study of the herbicide metamitron

Electroanalysis, 1994
AbstractThe electrochemical characteristics of the herbicide metamitron have been studied in the pH range 1 to 9 by applying several polarographic techniques, namely DCP, TAST, and DPP, adsorptive stripping voltammetry, and cyclic voltammetry with HMDE.

Toxicokinetics, Recovery, and Metabolism of Metamitron in Goat

Journal of Agricultural and Food Chemistry, 2003
Toxicokinetic behavior and metabolism studies of metamitron and its effect on the cytochrome P(450) content of liver microsomal pellet were carried out in black Bengal goats after a single oral administration at 278 mg kg(-1) and consecutive oral administration of 30 mg kg(-1) for 7 days.

Novel electrochemical procedure for the determination of metamitron

International Journal of Environmental Analytical Chemistry, 2018
ABSTRACTIn this paper, a chronopotentiometric method for the determination of herbicide metamitron (MTM) using a glassy carbon electrode (GCE) and a thin film mercury electrode (TFME) as working electrodes is presented. MTM provided a well-defined reductive peak in the Britton–Robinson buffer on both working electrodes.

Metamitron activity in tolerant and susceptible plants

Pesticide Science, 1977
AbstractThe herbicidal activity of metamitron, its inhibition of photosynthesis and its metabolism were studied in a number of plant species. An enzymic, light‐independent deamination produces an inactive metabolite. Metabolism is rapid in plants tolerant to metamitron, e.g.

Persistence of metamitron in a sandy loam soil

Bulletin of Environmental Contamination and Toxicology, 1976
Metamitron seems most likely to be applied at drilling or shortly afterwards. The results show that even under abnormally dry conditions, no more than 20% of the initial activity remained in the top 7 cm of soil at the time red beet were harvested. Some activity was detectable at a depth of 7.5–10 cm, but more than half of that still present was in the

Metamitron and Chloridazon Dissipation in a Silty Clay Loam Soil

Journal of Agricultural and Food Chemistry, 1995
The dissipation of chloridazon in a silty clay loam soil under laboratory and field conditions was similar to that of metamitron, and they were both affected by temperature and soil moisture. The t 1/2 of chloridazon, at 22% soil moisture, decreased from 76 to 14 days with temperature increase from 10 to 30 o C; the t 1/2 of metamitron, in the same ...

Absorption, translocation and metabolism of metamitron in Chenopodium album

Pest Management Science, 2011
Abstract BACKGROUND: In recent years, common lambsquarters ( Chenopodium album L.) populations from sugar beet fields in different European countries have responded as resistant to the as ‐triazinone metamitron. The

Influence of soil properties on the adsorption and mobility of metamitron

Communications in Soil Science and Plant Analysis, 1995
Abstract The adsorption and mobility of herbicide, metamitron, in 41 soils samples from the province of Salamanca (Spain) was studied. Thirty‐four of the samples assayed were from irrigated soils and seven were from natural, uncultivated soils with organic matter contents above 3%.
