Bentazone Leaching in Spanish Soils

Pesticide Science, 1996
Adsorption, incubation and soil-column experiments with bentazone [3-isopropyl-1H-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide] were carried out in ten different soils from the marches surrounding the Donana National Park (Huelva, SW Spain). Adsorption isotherms for the different soils showed a good fit with the Freundlich equation. Bentazone was poorly

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.

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 ...

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 ...

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 ...

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.

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 ...

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.

Phytoremediation experimentation with the herbicide bentazon

Remediation Journal, 1997
AbstractAn experiment was performed on six species of trees to determine the feasibility of remediating groundwater contaminated with an agricultural herbicide, bentazon, at a site in southern Louisiana. Fate studies on bentazon support that it is translocated to the plant leaves where it is degraded by photolysis to lower‐order derivative compounds ...

Sweet Corn Cultivar Sensitivity to Bentazon

Weed Technology, 2004
Five sweet corn cultivars were evaluated for tolerance to bentazon in five field experiments conducted during 2 yr in Ontario. Bentazon was applied postemergence (POST) at 1.08 and 2.16 kg ai/ha, the highest registered rate and twice the highest registered rate, respectively, used in sweet corn in Ontario.
