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.

Genetic diversity and phylogenetic relationships among and within Amaranthus spp. using RAPD markers

Revista Mexicana de Biodiversidad, 2020
Random Amplified Polymorphic DNA (RAPD) markers were used to investigate genetic diversity and phylogenetic relationships among 10 species belonging to the genus Amaranthus L. The results showed that the polymorphism in cultivated species was lower than

Herbicidas orgánicos alternativa al glifosato para el control de maleza en presiembra en el norte de Tamaulipas

AIA Avances en Investigación Agropecuaria, 2022
Introducción. El manejo agronómico del cultivo desde siembra hasta cosecha es mecanizado. Uno de los componentes más importantes es el control de malezas (Montes et al., 2013). El manejo químico de las malezas se basa en un grupo de herbicidas sintéticos

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.

Palmer Amaranth (Amaranthus palmeri) Adaptation to US Midwest Agroecosystems

Frontiers in Agronomy, 2022
Palmer amaranth (Amaranthus palmeriS. Watson) is one of the most troublesome agronomic weed species in the United States. Palmer amaranth is prevalent in the Southern Great Plains and the Southeastern United States, and its range is expanding northward through natural dispersal and human intervention.

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.

Enhancement of glyphosate efficacy on Amaranthus palmeri by exogenous quinate application

Pesticide Biochemistry and Physiology, 2019
Glyphosate is a widely used herbicide targeting the enzyme 5-enolpyruvylshikimate 3-phosphate synthase (EPSPS) in the aromatic amino acid biosynthesis pathway (shikimate pathway) and provoking accumulation of quinate, a secondary metabolite synthesized through a side branch of this pathway.

Characterization of the Amaranthus palmeri Physiological Response to Glyphosate in Susceptible and Resistant Populations [PDF]

Journal of Agricultural and Food Chemistry, 2015
The herbicide glyphosate inhibits the plant enzyme 5-enolpyruvylshikimate3-phosphate synthase (EPSPS) in the aromatic amino acid (AAA) biosynthetic pathway. The physiologies of an Amaranthus palmeri population exhibiting resistance to glyphosate by EPSPS gene amplification (NC-R) and a susceptible population (NC-S) were compared.

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 ...
