Precision phenotyping of imidazolinone-induced chlorosis in sunflower [PDF]

Breeding Science, 2014
Chlorosis level is a useful parameter to assess imidazolinone resistance in sunflower (Helianthus annuus L.). The aim of this study was to quantify chlorosis through two different methods in sunflower plantlets treated with imazapyr.

Subgenomic Distribution and Herbicide Cross-Resistance of <i>ALS</i> Gene Mutations in Allohexaploid <i>Echinochloa crus-galli</i>. [PDF]

Plant Direct
ABSTRACT Herbicide target site resistance in polyploid species is more complex than in diploids due to potential subgenome interactions. This study characterized mutations in the ALS gene across distinct subgenomes of hexaploid Echinochloa crus‐galli and evaluated the cross‐resistance patterns conferred by each mutation to various ALS‐inhibiting ...

Endocrine Disruptive Effects of the Herbicides Linuron, Chloridazon and Metribuzin on Bovine Granulosa Cells. [PDF]

Reprod Domest Anim
ABSTRACT Linuron, chloridazon and metribuzin are herbicides thought to have potential endocrine disruption (ED) effects. This study investigated the effects of linuron, chloridazon and metribuzin on bovine granulosa cell viability and oestrogen (E2) and progesterone (P4) secretion in vitro.

Analysis of multiple-herbicide resistant Amaranthus palmeri populations from Spain points to an introduction of the eccDNA from America. [PDF]

Pest Manag Sci
In this study, multiple herbicide resistant mechanisms have been confirmed in two Amaranthus palmeri populations from Spain that survived glyphosate‐ and ALS‐inhibitor herbicides. Our data suggest that the eccDNA and the mutations identified in the ALS gene are the result of an evolutionary event that occurred outside Spain.

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.

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.

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 ...
