Lethal Bentazone Intoxication – A Report of Two Cases

Journal of Forensic Sciences, 2017
AbstractThis study presents two cases of lethal bentazone poisonings, their clinical presentation, the course of the disease and the autopsy findings. The first is a 50‐year‐old male who had sprayed corn with a solution of bentazone and was admitted to the hospital with sweating, fever, nausea, vomiting of aqueous and hemorrhagic content, and bloody ...

Photocatalytic degradation of bentazon by TiO2 particles

Chemosphere, 1989
The degradation of 3-isopropy1–2,1,3-benzothiadiazin-4-one-2,2-dioxide, the herbicide bentazon, by AMI simulated sunlight has been investigated in the presence of aqueous suspensions of TiO2. The half-life of the degradation process is ca. 30 minutes at pH=2 and ca. 4 minutes at pH=7 in the presence of 0.5 g L−1 of TiO2.

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.) L.C. Wheeler var.pinnatifida(Stokes) L.C.

Influence of Climate and Additives on Bentazon

Weed Science, 1975
Experiments 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.

Modeling the THz spectrum of the bentazon

Chinese Optics Letters, 2011
Terahertz (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

Time effect on bentazone sorption and degradation in soil

Pest Management Science, 2004
Abstract 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 ...

Influence of the herbicide bentazon on soil microbial community

Microbiological Research, 1996
Changes in microbial numbers and activities in a soil in response to bentazon applied at 10 and 100 ppm were studied after 4 and 30 weeks of incubation in laboratory conditions. As regards the eight general and functional microbial groups studied (aerobic and anaerobic bacteria, fungi, aerobic and anaerobic N2-fixing bacteria, nitrifiers, aerobic and ...

Effects of Simulated Rainfall on Bentazon Activity

Weed Science, 1975
Simulated rainfall less than 8 hr after postemergence application of bentazon (3-isopropyl-1H-2,1,3-benzothiadiazin-(4)3H-one 2, 2-dioxide) reduced its activity on velvetleaf (Abutilon theophrastiMedic.) and common cocklebur (Xanthium pensylvanicumWallr.) in greenhouse studies.

Residuen van cyanazin, bentazon en de metabolieten 6- en 8-hydroxy-bentazon in suikermais

1987
Dit rapport beschrijft de ontwikkeling van een analyseprocedure voor de gelijktijdige bepaling van de herbiciden cyanazin, bentazon en diens twee metabolieten 6- en 8-hydroxy-bentazon, met behulp van HPLC. De methode is toegepast voor de bepaling van deze componenten in suikermais. Tijdens het onderzoek bleek dat, bij toevoeging van de hydroxy-bentazon

Residuen van bentazon in stamslabonen

1988
Stamslabonen, behandeld met 720 g/ha bentazon, bevatten drie weken na de bespuiting geen aantoonbare residuen bentazon. De bepalingsgrens bedraagt 0,02 mg/kg. De bepaling berust op hoge-drukvloeistofchromatografie met UV-detectie. Voor de clean-up werd gebruik gemaakt van acetonitril/hexaan-partitie gevolgd door aanrijking op een on-line geschakelde ...
