Rapid diagnosis of resistance to imidazolinone herbicides in barnyardgrass (Echinochloa crus-galli) and control of resistant biotypes with alternative herbicides [PDF]

Planta Daninha, 2013
The resistance of barnyardgrass (Echinochloa crus-galli) to imidazolinone herbicides is a worldwide problem in paddy fields. A rapid diagnosis is required for the selection of adequate prevention and control practices.

Tolerance to Imidazolinone Herbicides in Wheat [PDF]

Plant Physiology, 1992
An imidazolinone-tolerant wheat (Triticum aestivum L. em Thell) mutant in the winter wheat cultivar Fidel has been identified and characterized. The mutant was isolated from a population derived through seed mutagenesis of the variety with an aqueous solution containing sodium azide.

Design, Synthesis, and Evaluation of X-ray Crystal Structure, Biological Activities, DFT Calculations, and Molecular Docking of Phenyl Imidazolidin-2-One Derivatives

Crystals, 2020
Eight phenyl imidazolinone derivatives were synthesized from N2-(2,4-dimethylphenyl)-N1-methyformamidine (DPMF) via scaffold-hopping method using the ring-closure approach. The prepared compounds were verified using 1H and 13C NMR and HRMS spectroscopies.

Hypoxic Treatment Decreases the Physiological Action of the Herbicide Imazamox on Pisum sativum Roots

Plants, 2020
The inhibition of acetolactate synthase (ALS; EC 2.2.1.6), an enzyme located in the biosynthetic pathway of branched-chain amino acids, is the target site of the herbicide imazamox.

Residual da mistura formulada dos herbicidas imazethapyr e imazapic em solo de várzea sobre azevém (Lolium multiflorum Lam.) cultivado em sucessão ao arroz tolerante Carryover of the formulated mixture of the herbicides imazethapyr and imazapic in lowland soils, affecting ryegrass (Lolium multiflorum Lam.)

Ciência Rural, 2008
Herbicidas do grupo das imidazolinonas, como imazethapyr e imazapic, podem persistir no solo e afetar culturas não-tolerantes cultivadas em sucessão. O objetivo do trabalho foi avaliar o efeito residual da mistura formulada de imazethapyr+imazapic sobre ...

Resistência cruzada da losna-branca (Parthenium hysterophorus) aos herbicidas inibidores da enzima acetolactato sintase Ragweed parthenium (Parthenium hysterophorus) cross-resistance to acetolactate synthase inhibiting herbicides

Planta Daninha, 2006
A aplicação de um mesmo herbicida, ou de herbicidas com o mesmo mecanismo de ação, durante anos consecutivos, numa mesma área, pode resultar na seleção de biótipos de plantas daninhas resistentes a herbicidas.
