Phytostimulation of lowland soil contaminated with imidazolinone herbicides

International Journal of Phytoremediation, 2020
The phytostimulation is a phytoremediation technique that can be used to remediate area contaminated with herbicides. It is necessary to select plants with high capacity to stimulate soil microbial activity. The present work aimed at evaluating seven plant species regarding their ability to phytostimulate soil and enhance the degradation of the ...

Synthesis of 4,5-disubstituted imidazolinones-2

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1989
1. 4-Methyl-5-(α-oxo-Β-bromo-e-ethoxycarbonylpentyl)imidazolinone-2 reacts with diethylamine with migration of the electrophilic reaction center to give 4-diethylaminomethyl-5-(α-oxo-e-ethoxycarbonylpentyl)imidazolinone-2. 2. Sulfur-containing nucleophilic reagents and potassium benzoate enter into a nucleophilic substitution reaction ...

Syntheses of ?-functionally substituted 2-imidazolinones

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1979
1. The Mannich and Vilsmeier reactions with 4(5)-methyl-2-imidazolinone proceed with involvement of the C5(4) carbon atom. 2. The reaction of 4(5)-methyl-5(4)-piperidinomethyl-2-imidazolinone with a mixture of thioacetic acid and acetic anhydride gives 1-acetyl-4-acetylmercaptomethyl-5-methyl-2-imidazolinone. 3.

Abiotic degradation (photodegradation and hydrolysis) of imidazolinone herbicides

Journal of Environmental Science and Health, Part B, 2008
The abiotic degradation of the imidazolinone herbicides imazapyr, imazethapyr and imazaquin was investigated under controlled conditions. Hydrolysis, where it occurred, and photodegradation both followed first-order kinetics for all herbicides.

Zoysiagrass Seedhead Suppression with Imidazolinone Herbicides

Weed Technology, 2012
Options for suppressing zoysiagrass seedheads in managed turfgrass systems are limited. Experiments were conducted in 2010 and 2011 evaluating the use of imazamox (26, 52, and 70 g ai ha−1) or imazapic (52 g ai ha−1) for ‘Zenith' and ‘Meyer' zoysiagrass seedhead suppression. Imazamox and imazapic at ≥ 52 g ai ha−1suppressed Zenith zoysiagrass seedheads

Imidazolinone-Resistant Sunflower Tolerance to Imazapic

Weed Technology, 2009
Field trials were conducted in Georgia in 2007 to 2008 to evaluate the tolerance of three imidazolinone-resistant sunflower cultivars to POST applications of imazapic. There was no interaction between sunflower cultivar and herbicide treatment. When averaged over sunflower cultivars, imazapic, at 70 and 140 g ai/ha and applied at 30 d after planting ...

Synthesis and CNS Depressant Activity of Imidazolinone Glyoxylates

Journal of Pharmaceutical Sciences, 1973
Six new imidazolinone glyoxylates, which exist in tautomeric equilibria with hydroxyimidazole glyoxylates, were synthesized by a new type of Claisen rearrangement and evaluated in a neuropharmacological mouse profile. CNS depression was observed in several members of the class.

Role of Ferrihydrite in Adsorption of Three Imidazolinone Herbicides

Journal of Agricultural and Food Chemistry, 2001
Adsorption of the imidazolinone herbicides imazapyr, imazethapyr, and imazaquin on synthetic ferrihydrites, either freeze-dried or not-freeze-dried, has been studied. The synthetic ferrihydrites were characterized by X-ray diffraction, scanning electron micrographs, and specific area determination.

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.
