Investigating glyphosate resistance in Amaranthus palmeri biotypes from Turkey

Phytoparasitica, 2021
Amaranthus palmeri is a troublesome weed which is growing in importance worldwide. It causes serious competition in many crops. A. palmeri was introduced into Turkey 4–5 years ago and appears to adapt to different environmental conditions. Monoculture cropping systems and repeated use of the same herbicides have led to development of herbicide ...

Integrated genomic and transcriptomic approaches reveal oxidative stress adaptation mechanisms in a mesotrione‐resistant Amaranthus tuberculatus biotype

Pest Management Science, Volume 82, Issue 7, Page 6387-6398, July 2026.
Integrated GWAS and transcriptomics in a Canadian waterhemp biotype reveal mesotrione resistance is polygenic and metabolically driven. Significant SNPs and 187 herbicide‐responsive genes point to enhanced redox homeostasis, glutathione‐linked detoxification, lipid/secondary metabolism, and oxidative stress responses. Resistance arises from coordinated,

Amaranthus palmeri a New Invasive Weed in Spain with Herbicide Resistant Biotypes

Agronomy, 2020
Amaranthus palmeri is the most prominent invasive weed in agricultural land from North America, partly due to its propensity to evolve resistance to multiple herbicide sites of action.

Cirsium arvense management with electrical weed control and clopyralid

Pest Management Science, Volume 82, Issue 7, Page 6575-6584, July 2026.
Electrical weed control (EWC) treatments reduced Cirsium arvense biomass by ≤95% and suppressed new shoot emergence by 70–95%, achieving control comparable to clopyralid. Sequential or integrated applications enhanced efficacy, demonstrating EWC's potential as a nonchemical tool for perennial weed management in orchard systems.

Thirty years of glyphosate‐resistant crops and weeds: Current situation and future prospects

Pest Management Science, Volume 82, Issue 7, Page 5987-6009, July 2026.
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

Fendioxypyracil, a new and systemic PPO‐inhibiting herbicide for X‐spectrum weed control

Pest Management Science, Volume 82, Issue 7, Page 6794-6807, July 2026.
This graphical abstract presents the discovery and synthesis of PPO herbicide structures with a central pyridine core, showing molecular conformations, dose–response inhibition curves for PPO1 and PPO2, and comparative weed and grass control efficacy of fendioxypyracil versus other herbicides in greenhouse and field trials.

A dual tank precision sprayer to overcome antagonism of mixing dicamba and clethodim for control of volunteer corn in soybean

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract The mixing of clethodim and dicamba in the same tank could lead to reduced grass weed control, suggesting antagonism. Recently commercialized precision dual tank sprayers can apply two herbicides simultaneously through different boom systems, which may reduce potential herbicide antagonism for effective grass weed control.

Control of ALS- and EPSPS-Resistant Amaranthus palmeri by Alternative Herbicides Applied in PRE- and POST-Emergence [PDF]

Planta Daninha
: The emergence of resistant biotypes of the Amaranthus palmeri species in cotton production areas of the state of Mato Grosso, Brazil, generated the need for correct identification of this species and information on viable herbicidal tools for their ...

Differential response of Palmer amaranth (Amaranthus palmeri) seed germination and seedling emergence under variable environmental conditions

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Palmer amaranth (Amaranthus palmeri S. Watson) is a eudicot weed that is considered as one of the most problematic weed species. It is reported to overcome several environmental and management stresses under field conditions. Research was conducted in a growth chamber and greenhouse to evaluate the effects of different stress parameters such ...
