Acta Scientiarum. Agronomy, 2021 Amaranthus palmeri S. Waston is currently one of the most problematic weeds worldwide. Biotypes with resistance to herbicides such as glyphosate and ALS inhibitors are now present in almost all Argentinian cultivable areas.

Differential expression of genes associated with non‐target site resistance in
Pest Management Science, 2021 AbstractBACKGROUNDPoa annua is a pervasive grassy, self‐pollinating, weed that has evolved resistance to 10 different herbicide modes‐of‐action, third most of all weed species. We investigated constitutive overexpression of genes associated with non‐target site resistance (NTSR) in POAAN‐R3 and the response of those genes when treated with ...

Agronomy, 2023 A study was carried out to determine the ALS (acetolactate synthase)-inhibitor herbicide resistance in the Mexican grass Ixophorus unisetus, a troublesome weed in corn crops in Mexico. First, the resistance was confirmed in field screening assays.

Frontiers in Plant Science, 2021 Lolium rigidum is one the worst herbicide resistant (HR) weeds worldwide due to its proneness to evolve multiple and cross resistance to several sites of action (SoA).

Journal of Plant Protection Research, 2017 Three populations of silky bent grass (Apera spica-venti L.) were tested – one that is susceptible and two that are resistant to sulfonylureas. This study assessed the efficacy of control by different herbicides in a pot experiment and estimated the ...

Role of a novel I1781T mutation and other mechanisms in conferring resistance to acetyl-CoA carboxylase inhibiting herbicides in a black-grass population. [PDF]
PLoS ONE, 2013 BACKGROUND: Knowledge of the mechanisms of herbicide resistance is important for designing long term sustainable weed management strategies. Here, we have used an integrated biology and molecular approach to investigate the mechanisms of resistance to ...

Agronomy, 2023 Herbicide resistance is an important weed management issue. Glyphosate is the most dominant herbicide, which controls a broad spectrum of weeds, including grasses such as Lolium rigidum. Lolium rigidum is a major weed of winter crops in Australia that is developing glyphosate resistance in increasing numbers of populations and has been observed growing

Julius-Kühn-Archiv, 2014 The repetitive use of herbicides of a given mode of action as primary tools to control weeds in simplified cropping systems has led to the development of resistant populations.

Plants, 2019 Intentional use of low dosage of herbicides has been considered the cause of non-target resistance in weeds. However, herbicide drift could be a source of low dosage that could be detected by weeds and change their metabolism.

A quantitative genetic examination of non‐target‐site resistance applied to Avena species
Weed Research, 2018 SummaryQuantitative genetics tools can be used to assess whether using herbicides at low doses drive selection on standing genetic variation in populations leading to non‐target‐site resistance (NTSR). These tools are particularly important for estimating the number of genes involved and the potential speed of evolution.
