Environmental Behavior of Bentazon Herbicide
1994Bentazon 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 ...

Photolytic decomposition of Bentazone
Journal of Chemical Technology & Biotechnology, 1996The 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, 1996Abstract 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 ...

Modeling the THz spectrum of the bentazon
Chinese Optics Letters, 2011Terahertz (THz) spectra of bentazon are determined within the range of 0.3?2.4 THz at room temperature. Density functional methods are used to compute the THz spectra using three different programs: Gaussian03 for isolated-molecule form, DMol3 and CRYSTAL09 for solid-state forms. Among the three, the computed THz spectrum of CRYSTAL09 shows better bond

Influence of Climate and Additives on Bentazon
Weed Science, 1975Experiments were conducted in the growth chamber and greenhouse to determine the influence of humidity, temperature, simulated rainfall, and oil additives with bentazon [3-isopropyl-1H-2,1,3-benzothiadiazin-(4) 3H-one 2,2-dioxide] upon redroot pigweed (Amaranthus retroflexusL.) control.

Uptake and Translocation of Bentazon with Additives
Weed Science, 1977Several 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.) L.C. Wheeler var.pinnatifida(Stokes) L.C.

Phytoremediation experimentation with the herbicide bentazon
Remediation Journal, 1997AbstractAn 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 ...

Bentazone Leaching in Spanish Soils
Pesticide Science, 1996Adsorption, 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

Time effect on bentazone sorption and degradation in soil
Pest Management Science, 2004Abstract Previous sorption/desorption batch experiments have indicated that bentazone is weakly sorbed by soils. In addition, field experiments have shown that 4% of the bentazone sprayed can be leached to drainage water. In order to complete bentazone characterisation, we have assessed the effect of time on its behaviour in ...
