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 ...

Time-dependent adsorption of imazethapyr to soil

Weed Science, 2000
Abstract Time-dependent adsorption of imazethapyr was studied in the laboratory on a sandy loam soil at 16% moisture for 30 d. Soil pH was adjusted to 4.5 to 6.8. Concentration of imazethapyr in soil water declined rapidly within the first day of incubation for all soil pH levels, indicating rapid initial adsorption.

Maize cultivars differ in tolerance to imazethapyr

South African Journal of Plant and Soil, 2000
The low tolerance of maize (Zea mays L.) to imazethapyr ((±)-2-[4,5-dihydro-4 methyl-4-(1 -methylethyl)-5-oxo 1H-imidazol-2-yl]-5-ethyl-3-pyridinecarboxylic acid) resulted in extensive crop damage in 1992/93 due to residue carry-over from resistant soybean (Glycine max L.).

Spatial variability of imazethapyr sorption in soil

Weed Science, 1999
A significant limitation in using sorption coefficients (Kd) to predict solute transport through natural soils is the spatial variability of soil properties over large field areas. Spatial variability inKdfor imazethapyr was determined on representative samples from a 31.4-ha field, covering a pH range from 4.9 to 7.6 and an organic carbon (OC) range ...

Carryover of Imazethapyr and Imazapic to Nontolerant Rice

Weed Technology, 2010
The present work aimed to evaluate plant injury caused by residues in the soil of the formulated mixture of imazethapyr and imazapic to a nontolerant genotype of rice (IRGA 417) drilled at 371 and 705 d after herbicide application (DAA). Herbicide carryover reduced up to 55% of the grain yield of the IRGA 417 drilled at 371 DAA, and plant injury was ...

Imidazolinone-Tolerant Rice Response to Imazethapyr Application

Weed Technology, 2006
Greenhouse research was conducted to evaluate shoot and root growth response of imidazolinone-tolerant (IT) rice cultivars to imazethapyr applied postemergence at various rates and application timings. Imazethapyr was applied at 70, 140, and 280 g ai/ha to IT cultivars ‘CL 121’ and ‘CL 161’ in the one- to two-leaf and three- to four-leaf growth stages.

EVALUATION OF IMAZETHAPYR FOR WEED MANAGEMENT IN CHICKPEA

Plant Archives
A field experiment was carried out at the Agricultural Farm, Palli Siksha Bhavana, Visva-Bharati, during the rabi season of 2020-21 to investigate the impact of imazethapyr in chickpea weed management. The experiment was carried out in a randomized block design, which contains nine treatments and three replications. The treatments include, pre and post
