Influence of metal salts on the photodegradation of imazapyr, an imidazolinone pesticide

open access: yesPest Management Science, 2006
AbstractThe behaviour of imazapyr (2‐(4‐isopropyl‐4‐methyl‐5‐oxo‐2‐imidazolin‐2‐yl)nicotinic acid), a broad spectrum herbicide of the imidazolinone family, has been studied under UV radiation in the presence of metal salts. Complexation interactions between imazapyr and metal ions decreased imazapyr photolysis.

Improving the Imazapyr Degradation by Photocatalytic Ozonation: A Comparative Study with Different Oxidative Chemical Processes

open access: yesProcesses, 2020
The degradation of imazapyr (C13H15N3O3), an active element in the aqueous solution of commercial herbicide, was investigated. This study was the first to evaluate in a comprehensive manner the efficiency of advanced oxidation processes for imazapyr ...

The fate of imazapyr in a Swedish railway embankment

Pest Management Science, 2004
Abstract The long‐term fate of the herbicide imazapyr [2‐(4‐isopropyl‐4‐methyl‐5‐oxo‐2‐imidazolin‐2‐yl)nicotinic acid] applied to a Swedish railway embankment was studied. Imazapyr was applied at 750 and 1500 g ha −1 by a spraying train used for full‐scale herbicide ...

Degradation of the herbicide imazapyr by Fenton reactions

Environmental Chemistry Letters, 2004
The degradation of the herbicide imazapyr has been carried out by three advanced oxidation processes involving iron ions as catalysts: Fenton’s reagent, photo-Fenton and electro-Fenton. We show that all processes are rapid and efficient. The kinetic rate constant was found to be k=5.4×109 M−1 s−1. The mineralization of imazapyr is almost complete using
