Isolation and characterization of a new imidazolinone‐tolerant mutant in cotton

Crop Science, 2022
AbstractCotton (Gossypium hirsutum L.) cultivars resistant to different herbicides have generated important advances in crop management. There is a wide range of cotton resistance to herbicides, however, commercial imidazolinone (IMI)‐tolerant cultivars are not available.

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.

Faster degradation of herbicidally-active enantiomer of imidazolinones in soils

Chemosphere, 2010
Imidazolinones are chiral herbicides, comprised of two enantiomers with differential herbicidal activity. In this study, the selective degradation of enantiomers of the three imidazolinone herbicides, imazapyr, imazethapyr and imazaquin, was determined in a variety of soils selected to cover a broad range of physico-chemical characteristics.

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.

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 ...

Imidazolinone herbicides for weed control in greengram

Indian Journal of Weed Science, 2016
A field experiment to study the efficacy of imidazolinone herbicides in greengram was conducted during Kharif seasons of 2012 and 2013. Ten weed control treatments viz. imazethapyr at 50 and 70 g, premix of imazethapyr + imazamox at 60 and 70 g/ha, both applied as post-emergence at 20 days after sowing; pendimethalin 1000 g and premix of pendimethalin +

Synthesis of ketovinyl derivatives of 2-imidazolinone

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1980
1. The reaction of 4(5)-methyl-2-imidazolinone with crotonyl chloride, chlorovinyl phenyl ketone or chlorovinyl n-amyl ketone in the presence of AlCl3 respectively, gives 4-methyl-5-crotonyl-, 4-methyl-5-phenylketovinyl- or 4-methyl-5-n-amylketovinyl-2-imidazolinone. 2.
