The Metabolic Fate of Bentazon in the Rat

Xenobiotica, 1972
1. An oral dose of [14C]bentazon, a new herbicide, was rapidly and almost quantitatively absorbed in rats. The radioactivity was rapidly excreted, mostly in the 24-h urine; only traces were secreted into the bile.2. [14C]Bentazon was rapidly distributed in rats.

Fatal overdose of the herbicide bentazone

Forensic Science International, 2003
A 59-year-old woman who intentionally ingested 100-200 ml Basagran was taken to the hospital with a cardiac arrest 2 days after she had consumed the herbicide. During this period she suffered vomiting, urination and diarrhoea and she was drowsy with a muddled speech.

Bentazon Degradation in Soil:  Influence of Tillage and History of Bentazon Application

Journal of Agricultural and Food Chemistry, 1996
Laboratory studies determined the fate of bentazon (3-isopropyl-1H-2,1,3-benzothiadiazin-4(3H)one 2,2-dioxide) in soil as affected by tillage and history of application. Bentazon degradation in two soils from Mississippi and three soils from Illinois under conventional-tillage (CT) and notillage (NT) (3-18 years) with varying histories of bentazon ...

Lysimeter experiments on bentazon

Chemosphere, 1991
Abstract The leaching behaviour, distribution, and metabolism of the herbicide bentazon within two years following application was investigated by a lysimeter study with undisturbed soil monolith and using the radiolabelled compound. This was achieved by analyzing compounds appearing in the leachate as well as analyzing radiolabelled residues ...

Differential bentazon metabolism and retention of bentazon metabolites by plant cell cultures

Pesticide Biochemistry and Physiology, 1989
Abstract Bentazon [3-(1-methylethyl)-(1 H )-2,1,3-benzothiadiazin-4(3 H )-one 2,2-dioxide] was metabolized to 6-O-β-glucose-bentazon (6-O-G) by suspension-cultured cells of alfalfa ( Medicago sativa L.), carrot ( Daucus carota L.), corn ( Zea mays L.), potato ( Solanum tuberosum L.), rice ( Oryza sativa L.), tobacco ( Nicotiana tabacum L.), and

The mechanism of bentazon selectivity

Pesticide Biochemistry and Physiology, 1975
Abstract Absorption, translocation and metabolism of [14C]3-isopropyl-2,1,3-benzothiadiazin-4-one-2,2-dioxide (bentazon) by several plant species were investigated to determine the mechanism of bentazon selectivity. Marked selective phytotoxicities were observed between resistant rice (Oryza sativa L.) and susceptible Cyperus serotinus Rottb.

Photolytic decomposition of Bentazone

Journal of Chemical Technology & Biotechnology, 1996
The photolytic decomposition of the herbicide Bentazone (3-isopropyl-1H-2,1,3-benzothiadiazin-4-3H-one 2,2 dioxide) has been conducted by direct polychromatic UV radiation, and by the combination of that UV radiation with hydrogen peroxide. The experiments were performed at various temperatures and pH values, and the initial hydrogen peroxide ...

Kinetics of the bentazone herbicide ozonation

Journal of Environmental Science and Health . Part A: Environmental Science and Engineering and Toxicology, 1996
Abstract The kinetics of ozonation of the herbicide Bentazone (3‐isopropyl‐lH‐2,1,3‐benzothiadiazin‐4–3H‐one 2,2 dioxide) is studied, the experiments being carried out in a bubble reactor, and using a porous plate as gas sparger. The increases of temperature, ozone partial pressure, initial Bentazone concentration and pH values under 5 have a positive ...

Environmental Behavior of Bentazon Herbicide

1994
Bentazon is a postemergence herbicide used in early spring to early summer in many crops, usually at application rates of 1.0 kg a.i./ha. Its selectivity is based on the ability of the crop plants to metabolize bentazon quickly to 6-OH- and 8-OH-bentazon and conjugate these with sugars, while weeds do not, so that photosynthesis is disrupted and the ...

Uptake and Translocation of Bentazon with Additives

Weed Science, 1977
Several experiments were conducted to determine the influence of temperature, relative humidity, leaf age, and additives on14C-bentazon [3-isopropyl-1H-2,1,3-benzothiadiazin-(4)3H-one 2,2-dioxide] uptake and translocation by redroot pigweed (Amaranthus retroflexusL.), wild mustard [Brassica kaber(DC.)
