ABIOTIC DEGRADATION OF IMAZETHAPYR IN AQUEOUS SOLUTION

Journal of Environmental Science and Health - Part B Pesticides, Food Contaminants, and Agricultural Wastes, 2002
The photodegradation of imazethapyr [2-(4,5-dihydro-4-méthyl-4-(1-méthylethyl)-5-oxo-1H-imidazol-2-yl)-5-ethyl-3-pyridinecarboxylic acid] in aqueous solution in the presence of titranium dioxide (TiO2) and humic acids (HA) at different ratios of herbicide/TiO2 and herbicide/humic acids was studied at pH 7.0.

Enantioselective phytotoxicity of the herbicide imazethapyr in rice

Chemosphere, 2009
Research increasingly suggests that enantiomer selectivity may be a part of the toxicological effects of chiral contaminants. In this study, we selected Japonica rice variety Xiushui 63 seedlings to evaluate the enantioselectivity of imazethapyr (IM).

Photocatalytic degradation of imazethapyr herbicide at TiO2/H2O interface

Chemosphere, 2005
The photocatalytic degradation of imazethapyr, a herbicide of the imidazolinone family, was investigated in an aqueous suspension of titanium dioxide used as a catalyst. A pseudo-first order kinetic model was employed to discuss the results. The effect of catalyst loading, initial concentration of imazethapyr, hydrogen peroxide, pH value, and ...

Imazethapyr disrupts plant phosphorus homeostasis and acquisition strategies

Journal of Hazardous Materials, 2023
The deficiency of essential mineral nutrients caused by xenobiotics often results in plant mortality or an inability to complete its life cycle. Imazethapyr, a widely utilized imidazolinone herbicide, has a long-lasting presence in the soil-plant system and can induce toxicity in non-target plants.

Enantioselectivity in the Phytotoxicity of Herbicide Imazethapyr

Journal of Agricultural and Food Chemistry, 2009
Chiral compounds usually behave enantioselectively in phyto-biochemical processes. With the increasing application of chiral herbicides, their enantioselective phytotoxicity to plants merits further study, and little information is available in this area.

Degradation and Field Persistence of Imazethapyr

Weed Science, 1990
The volatilization, photolysis, microbial degradation, and field persistence of imazethapyr were studied using formulated and14C-labeled imazethapyr. Volatilization losses from soil were less than 2%. Photodecomposition losses of up to 8% occurred from soil and up to 52% from a glass slide with no soil. Significantly greater photodecomposition occurred

Microbial degradation of imazaquin and imazethapyr

Weed Science, 1997
Laboratory studies were conducted to investigate the processes of imazaquin and imazethapyr degradation in soil. Microbial degradation of14C-imazaquin and14C-imazethapyr was monitored by measuring14CO2evolution compared to nonsterile soil.14CO2evolution was greatest from carboxyl-labeled imazaquin and imazethapyr compared to ring-labeled imazaquin and ...
