Interaction of metamitron and metolachlor with organic and inorganic smectites

Toxicological and Environmental Chemistry, 1996
To obtain useful data for the interpretation of the adsorption results in pesticide‐clay‐water systems a study of the interaction of the herbicides metamitron and metolachlor with montmorillonite saturated with inorganic cations and trimethylalkylammonium cations using x‐ray diffraction (XRD) and infrared spectroscopy (IR) was performed.

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

Adsorption of 1,2,4-triazine pesticides metamitron and metribuzin on lignin

Microchemical Journal, 2000
The 1,2,4-triazine pesticides, metamitron [4-amino-3-methyl-6-phenyl-1,2,4-triazin-5(4H)-one] and metribuzin [4-amino-3-methylthio-6-tert-butyl-1,2,4-triazin-5(4H)-one] are adsorbed on lignin. The adsorption can be followed by measuring polarographically the concentration of the free pesticide in a slurry, obtained by dispersing rot-wood lignin in an ...

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.

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

Behaviour of metamitron and hydroxy‐chlorothalonil in low‐humic sandy soils

Pesticide Science, 1999
The behaviour of the herbicide metamitron and of the main transformation product, hydroxy-chlorothalonil (HTI), of the fungicide chlorothalonil was studied to assess the risk of leaching from low-humic sandy soil. The adsorption of metamitron corresponded to a Kom value of about 60 dm3 kg−1 (moderate adsorption).

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.

Adsorption‐leaching study of the herbicides metamitron and chloridazon

Pesticide Science, 1991
AbstractFreundlich isotherms were obtained for the adsorption equilibrium of the herbicides metamitron and chloridazon with the components of a representative soil in a pesticide concentration range of 10‐1000 γg ml−1 for metamitron and 10‐500 μg ml−1 for chloridazon.The mobility of these herbicides through soil columns was also studied using the ...

EFFICACY OF METAMITRON IN APPLE THINNING IN SERBIA.

Communications in agricultural and applied biological sciences, 2016
The thinning of fruits is a required pomotechnical measure in intensive fruit production which ensures the production of good quality fruits and high yields. Metamitron, known as inhibitor of photosynthesis, has been successfully used in the thinning of apple fruits.

Study of the conditions for the determination of metamitron by differential pulse polarography

Fresenius' Zeitschrift für analytische Chemie, 1989
The electrochemical behaviour of the herbicide 4-amino-3-methyl-6-phenyl-1,2,4 triazine-5(4H)-on (Metamitron) is studied in aqueous medium using voltammetric techniques, with the ionic strength adjusted to 0.1 mol/l in sodium perchlorate and using a Britton-Robinson buffer.
