Enantioselective effects of herbicide imazapyr onArabidopsis thaliana

Journal of Environmental Science and Health, Part B, 2014
The enantioselective toxicity of chiral herbicides in the environment is of increasing concern. To investigate the enantioselective effects of the chiral herbicide imazapyr on target organisms, we exposed Arabidopsis thaliana to imazapyr enantiomers and racemate. The results show that imazapyr was enantioselectively toxic to A. thaliana.

Copper(II) Complexes of the Imidazolinone Herbicide Imazapyr

Journal of Agricultural and Food Chemistry, 1996
The copper(II) complexes formed by the imidazolinone herbicide imazapyr [(±)-2-(4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl)nicotinic acid] were studied in aqueous solution by potentiometric and spectroscopic techniques. Imazapyr acts as a chelating molecule and is effective over a wide pH range.

Response Surface Analysis of Control of Red Alder and Vine Maple with Glyphosate-Imazapyr and Triclopyr-Imazapyr

Western Journal of Applied Forestry, 1995
Abstract Quadratic response functions were demonstrated for predicting crown reduction of red alder (Alnus rubra) and vine maple (Acer circinatum) after application of the herbicides glyphosate and triclopyr in combinations with imazapyr.

Modelling the leaching of imazapyr in a railway embankment

Pest Management Science, 2006
Abstract The use of herbicides on railway tracks is known to present a risk to groundwater, but little is known of the mechanisms influencing leaching through the coarse material used to construct railway embankments. Therefore, in the present study, four different models based on the convection–dispersion equation (CDE) were compared

Electrochemical oxidation of imazapyr with BDD electrode in titanium substrate

Chemosphere, 2014
In this work we have studied the treatment of imazapyr by electrochemical oxidation with boron-doped diamond anode. Electrochemical degradation experiments were performed in a one-compartment cell containing 0.45 L of commercial formulations of herbicide in the pH range 3.0-10.0 by applying a density current between 10 and 150 mA cm(-2) and in the ...

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 ...

Saltcedar (Tamarixspp.) Management with Imazapyr

Weed Technology, 1998
During the 20th century, naturalized saltcedar has become common within major tributaries throughout the western United States. Often growing in nearly monocultural stands, saltcedar is suspected of lowering water tables, thus destroying wetlands and wildlife habitats.

Photocatalytic degradation of imazapyr using mesoporous Al2O3–TiO2 nanocomposites

Separation and Purification Technology, 2015
Abstract Mesoporous Al 2 O 3 –TiO 2 nanocomposites at different Al 2 O 3 contents (0–5 wt.%) have been synthesized through a facile sol–gel method using tetrabutyl orthotitanateand and aluminum-tri- sec -butoxide as a precursors for TiO 2 and Al 2 O 3 sources. XRD and Raman spectra confirmed that highly crystalline anatase TiO 2 phase was formed

Persistence and sorption of imazapyr in three Argentinean soils

Environmental Toxicology and Chemistry, 2013
Abstract   Imazapyr is a herbicide widely used for weed control in imidazolinone-tolerant sunflower. Imazapyr has a high potential for leaching into groundwater because it is highly water-soluble, persistent in soil, and only weakly sorbed by soils.

Dissipation of imazapyr, flumetsulam and thifensulfuron in soil

Weed Research, 1997
SummaryThe degradation of imazapyr, flumetsulam and thifensulfuron applied at 500.40 and 30 g active ingredient (a.i.) ha‐1, respectively, to silt loam soil was studied under laboratory and field conditions. Herbicide residues were analysed by a lentil (Lens culinarits L.) bioassay.
