Resistance to post-emergent herbicides is becoming common for grass weeds on New Zealand wheat and barley farms.

open access: yesPLoS ONE, 2021
To estimate the prevalence of herbicide-resistant weeds, 87 wheat and barley farms were randomly surveyed in the Canterbury region of New Zealand. Over 600 weed seed samples from up to 10 mother plants per taxon depending on abundance, were collected ...

Evolution der Herbizidresistenz in Alopecurus myosuroides und Apera spica-venti im deutschen Getreideanbau der letzten 15 Jahre

open access: yesJulius-Kühn-Archiv, 2020
Das Vorkommen von Herbizidresistenzen bei Ungräsern nimmt in den letzten 30 Jahren in Deutschland kontinuierlich zu. Dies gilt sowohl für die Anzahl der betroffenen Arten, die regionale Verbreitung, den Resistenzgrad, die Anzahl der Aktivsubstanzen, der ...

Potential of plant species for bioremediation of soils applied with imidazolinone herbicides [PDF]

open access: yesPlanta Daninha, 2014
Imidazolinone herbicides present physicochemical characteristics that allow them to persist longer in environment, with increased chances of soil and water contamination, as well as carryover effects on subsequent crops.

Resistência de plantas aos herbicidas inibidores da acetolactato sintase Plant resistance to acetolactate synthase-inhibiting herbicides

open access: yesPlanta Daninha, 2002
A resistência de plantas aos herbicidas é conseqüência, na maioria das vezes, de mutação ou da preexistência de genes que conferem resistência à população.

Influence of herbicide doses on efficacy and yield in winter cereal on the example of blackgrass and loose silky-bentgrass

open access: yesJulius-Kühn-Archiv, 2016
Agriculture today is facing the challenge to both keeping the input of herbicides into nature at a low level and aiming for high yields while avoiding low efficacies caused by resistance evolution.

A Possible Role for Platelet-Activating Factor Receptor in Amyotrophic Lateral Sclerosis Treatment

open access: yesFrontiers in Neurology, 2018
Amyotrophic lateral sclerosis (ALS) is the third most prevalent neurodegenerative disease affecting upper and lower motor neurons. An important pathway that may lead to motor neuron degeneration is neuroinflammation.

Multiple mutations in the EPSPS and ALS genes of Amaranthus hybridus underlie resistance to glyphosate and ALS inhibitors [PDF]

open access: yesScientific Reports, 2020
AbstractAmaranthus hybridus is one of the main weed species in Córdoba, Argentina. Until recently, this weed was effectively controlled with recurrent use of glyphosate. However, a population exhibiting multiple resistance (MR2) to glyphosate and imazamox appeared in a glyphosate resistant (GR) soybean field, with levels of resistance up to 93 and 38 ...

Pro-197-Ser Mutation in ALS and High-Level GST Activities: Multiple Resistance to ALS and ACCase Inhibitors in Beckmannia syzigachne

open access: yesFrontiers in Plant Science, 2020
American sloughgrass (Beckmannia syzigachne Steud.) is one of the most troublesome weeds infesting wheat and canola fields in China. Some biotypes cannot be controlled, either by acetolactate synthase (ALS) or acetyl coenzyme A carboxylase (ACCase ...
