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.

Impact of imazethapyr on the microbial community structure in agricultural soils

Chemosphere, 2010
Large amounts of imazethapyr were applied for weed control in cultivation fields in China, but their effects on the soil microbial community remains unclear. In this study, two agricultural soils, a silty loam (HS) and a loamy soil (QL), were spiked with imazethapyr (CK, 0.1, 1 and 10 mg kg(-1)) and incubated for 1, 15, 30, 60, 90 and 120 d.

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 ...

Modelling the photochemistry of imazethapyr in rice paddy water

Science of The Total Environment, 2018
In this work the photochemistry of imazethapyr, an imidazolinone herbicide used in rice crops, was modelled in rice paddy water. The photochemical half-life time of the herbicide was assessed by means of the APEX software (Aqueous Photochemistry of Environmentally occurring Xenobiotics) taking into account the direct photolysis, the reactions with ...

Transport of Imazethapyr in Undisturbed Soil Columns

Soil Science Society of America Journal, 1992
Abstract The disappearance of imazethapyr [(±)‐2‐[4,5‐dihydro‐4‐methyl‐4‐(1‐methylethyl)‐5‐oxo‐1H‐imidazole‐2‐yl]‐5‐ethyl‐3‐pyridinecarboxylic acid] from soil solution was investigated to evaluate the transport of imazethapyr in undisturbed soil columns.

Weed Control in Sericea Lespedeza with Imazethapyr

Weed Technology, 2005
Field studies were conducted to determine the feasibility of using imazethapyr applied preemergence (PRE) and postemergence (POST) for weed control in sericea lespedeza. In the POST experiment, imazethapyr was applied at 0, 71, 142, and 213 g ai/ha to mature, recently mowed stands of sericea lespedeza.

Enantioselectivity effects of imazethapyr enantiomers to metabolic responses in mice

Pesticide Biochemistry and Physiology, 2020
Imazethapyr (IMZT) is a typical chiral pesticide with two enantiomers with the R-IMZT having the main herbicidal activity. However, the enantioselectivity of the effects of IMZT enantiomers on human and animals is still unclear. In this study, a nuclear magnetic resonance (NMR)-based metabolomics method and determination of oxidative stress were used ...

Effect of Imazethapyr on Perennial Grasses

Weed Technology, 1995
Experiments were conducted near Scottsbluff, NE in 1991 and 1992 to evaluate the selectivity of imazethapyr for weed control in blue grama, intermediate wheatgrass, little bluestem, Russian wildrye, switchgrass, and western wheatgrass. Imazethapyr reduced weed biomass in all seedings and injured all perennial grasses 12 days after treatment (DAT ...
