Abiotic degradation (photodegradation and hydrolysis) of imidazolinone herbicides
Journal of Environmental Science and Health, Part B, 2008The 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, 2012Options 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, 2009Field 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, 2016A 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, 19801. 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.

Synthesis of 4,5-disubstituted imidazolinones-2
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19891. 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, 19791. 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.
