Target-site resistance to acetolactate synthase (ALS)-inhibiting herbicides in Amaranthus palmeri from Argentina
(John Wiley & Sons Ltd, 2017-12)
BACKGROUND: Herbicide-resistant weeds are a serious problem worldwide. Recently, two populations of Amaranthus palmeri with suspected cross-resistance to acetolactate synthase (ALS)-inhibiting herbicides (R1 and R2) were ...
Inheritance of glyphosate resistance in Lolium perenne and hybrids with Lolium multiflorum
(2015-05)
Glyphosate-resistant Lolium species have been selected in weed communities where glyphosate is the herbicide used almost exclusively for weed control. The rate of evolution of herbicide resistance is highly influenced by ...
Las malezas se defienden: resistencia a múltiples herbicidas
(2017-04)
A nivel mundial, en la última década el número de malezas resistentes a más de un herbicida se ha incrementado en un 75 %. En nuestra región, el ryegrass no se queda atrás y cada vez es más frecuente la resistencia a varios ...
Effect of Ahasl1-1 and Ahasl1-4 alleles on herbicide resistance and its associated dominance in sunflower
(John Wiley & Sons Ltd, 2018-09-06)
BACKGROUND: Acetohydroxyacid synthase large subunit 1 (Ahasl1) is a multiallelic locus involved in herbicide resistance in sunflower. Ahasl1-1 and Ahasl1-4 alleles harbor different point mutations that lead to different ...
AHAS herbicide resistance endowing mutations: Effect on AHAS functionality and plant growth
(Oxford University Press, 2010-09)
Twenty-two amino acid substitutions at seven conserved amino acid residues in the acetohydroxyacid synthase (AHAS) gene have been identified to date that confer target-site resistance to AHAS-inhibiting herbicides in ...
Herbicide resistant weeds: A call to integrate conventional agricultural practices, molecular biology knowledge and new technologies
(Elsevier Ireland, 2019-09)
Herbicide resistant (HR) weeds are of major concern in modern agriculture. This situation is exacerbated by the massive adoption of herbicide-based technologies along with the overuse of a few active ingredients to control ...
Amicarbazone, a New Photosystem II Inhibitor
(Weed Sci Soc Amer, 2014)
IMI resistance associated to crop-weed hybridization in a natural Brassica rapa population: characterization and fate
(2017-03)
Wild turnip (Brassica rapa) is a common weed and a close relative to oilseed rape (Brassica napus). The Clearfield® production system is a highly adopted tool which provides an alternative solution for weed management, but ...
Experimental methods for estimation of plant fitness costs associated with herbicide-resistance genes
(Weed Science Society of America, 2015-01)
Since the beginning of agriculture, crops have been exposed to recurrent invasion by weeds that can impose severe reductions in crop quality and yield. There have been continuing efforts to reduce the impacts of weeds on ...
Efficacy of imidazolinone herbicides applied to imidazolinone-resistant maize and their carryover effect on rotational crops
(ELSEVIER SCI LTD, 2005)
A field study was performed in imidazolinone-resistant maize in order to evaluate the effectiveness and carryover effect on rotational crops of two formulated mixtures of imidazolinone herbicides: imazapyr plus imazapic ...
