Biotransformation of Metamitron by Human P450 Expressed in Transgenic Tobacco Cell Cultures

Journal of Environmental Science and Health, Part B: Pesticides, Food Contaminants, and Agricultural Wastes, 2006
In the present investigation, the oxidative metabolism of 14C-labeled metamitron was examined in plant cell cultures of tobacco overexpressing human P450 enzymes CYP1A1 or CYP1A2; special interest was in the aromatic hydroxylation of the herbicide. The oxidative metabolites deaminometamitron (DAM) and 4-hydroxydeaminometamitron (4-HDAM) were found in ...

Voltammetric Determination of Metamitron with an Electrogenerated Molecularly Imprinted Polymer Microsensor

Electroanalysis, 2007
AbstractA molecularly imprinted polymer microsensor was synthesized onto the surface of a carbon fiber microelectrode (CFME) by cyclic voltammetry between −0.1 V and +1.35 V at a scan rate of 50 mV s−1. The monomers aniline and o‐phenylenediamine (o‐PD) were electrocopolymerized in the presence of the template (metamitron) in an aqueous medium of 0.1 M

Recovery from inhibition of photosynthesis by metamitron in various plant species

Weed Research, 1979
Summary:Inhibition of photosynthesis by metamitron in the rooting medium and its subsequent recovery after transfer of the roots to herbicide‐free nutrient solution was measured in eight plant species.Fast and complete recovery within a few hours after treatment showed that metamitron, once absorbed, was rapidly and completely inactivated in the leaves

Differential-pulse adsorptive stripping voltammetry of the herbicides metamitron and isometiozine

Fresenius' Journal of Analytical Chemistry, 1991
The electrochemical behaviour of the herbicides metamitron and isometiozine has been studied by adsorptive stripping voltammetry for electro-adsorptive potentials of −350 mV and −500 mV, respectively, with Britton-Robinson buffer solution and adjusting the ionic strength to 0.25 mol/l in NaClO4.

Transformation of metamitron in water-sediment systems: Detailed insight into the biodegradation processes

Science of The Total Environment, 2017
Metamitron and its main metabolite desamino-metamitron are frequently detected in surface waters. To date, there are no studies targeting metamitron degradation in water-sediment systems. Therefore, the aim of this study was to trace the fate of metamitron in a water-sediment system using 13C-isotope labeling.

Efficiency of fruitlet thinning in ‘Granny Smith’ apples by use of metamitron

Acta Horticulturae, 2018
In this paper the results of chemical fruit thinning in the apple cultivar 'Granny Smith' carried out with the herbicide Brevis® containing 150 g kg(-1) of metamitron as the active ingredient are reported. In two treatments, the effect of this compound was enhanced by NAA (1-naphthaleneacetic acid).

Local spread of metamitron resistant Chenopodium album L. patches.

Communications in agricultural and applied biological sciences, 2012
Molecular markers can provide valuable information on the spread of resistant weed biotypes. In particular, tracing local spread of resistant weed patches will give details on the importance of seed migration with machinery, manure, wind or birds. This study investigated the local spread of metamitron resistant Chenopodium album L.

Metamitron-resistant Chenopodium album from sugar beet: cross-resistance profile.

Communications in agricultural and applied biological sciences, 2007
In recent years, in several of the Belgian sugar beet growing regions, farmers have been confronted with unsatisfactory control of fat hen (Chenopodium album L.). Greenhouse bioassays conducted on reference C. album populations and on "suspected" populations from sugar beet fields where poor fat hen control had been observed, revealed that all ...
