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 ...

Green foxtail (Setaria viridis) and puncturevine (Tribulus terrestris) control in imazamox‐, quizalofop‐, and nicosulfuron‐resistant grain sorghum in semiarid Central Great Plains

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Recent commercialization of herbicide‐resistant (HR) grain sorghum [Sorghum bicolor (L.) Moench] hybrids, including iGrowth, DoubleTeam, and Inzen enables the use of imazamox, quizalofop, and nicosulfuron, respectively, for annual grass weed control.

Integrated Palmer Amaranth Management in Glufosinate-Resistant Cotton: I. Soil-Inversion, High-Residue Cover Crops and Herbicide Regimes

Agronomy, 2012
A three year field experiment was conducted to evaluate the role of soil-inversion, cover crops and herbicide regimes for Palmer amaranth between-row (BR) and within-row (WR) management in glufosinate-resistant cotton.

Comparison of methods to recover amaranth weed seeds from manure

Agricultural & Environmental Letters, 2022
One pathway by which Palmer amaranth (Amaranthus palmeri S. Watson) invades new areas is through importation of contaminated livestock feed, which then contaminates land‐applied manure.

Palmer Amaranth Control by Glufosinate Depends on Application Time of Day

Journal of Cotton Science, 2021
Glufosinate is used widely to control glyphosate-resistant Palmer amaranth (Amaranthus palmeri S. Wats.) in cotton (Gossypium hirsutum L.). Previous research has shown weed control with several herbicides, including glufosinate, can be affected by application time of day.

Target‐site and non‐target‐site mechanisms confer multiple herbicide resistance in waterhemp (Amaranthus tuberculatus) accessions from Wisconsin

Pest Management Science, Volume 82, Issue 6, Page 5695-5706, June 2026.
The A101 accession is the first confirmed case of hydroxyphenyl pyruvate dioxygenase resistance in Amaranthus tuberculatus in Wisconsin, and the first report of P450s associated with atrazine resistance in A. tuberculatus globally. Abstract BACKGROUND A preliminary screening identified a multiple herbicide‐resistant waterhemp, Amaranthus tuberculatus ...

Brassica biofumigation cover crops in US agroecosystems: A systematic review of research from 2014 to 2024

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Biofumigation with brassica cover crops (BCCs) is gaining momentum in the United States as an ecologically sound alternative to chemical pest suppression in agricultural systems. This review critically evaluates the impacts of Brassica species on soil health, weed suppression, disease mitigation, and control of plant‐parasitic nematodes (PPNs)

Palmer Amaranth (Amaranthus palmeri) in the Pacific Northwest: Glyphosate-Resistance Confirmation and Efficacy of Selected Herbicides

Weed Technology
Herbicide-resistant Palmer amaranth has been problematic within the United States for the past 30 years. The recent introduction of Palmer amaranth into the Pacific Northwest (PNW) prompted extensive surveys in 2023 and 2024 to collect seed samples for ...

Determining if preemergent herbicide injury on ThryvOn cotton alters management strategies

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Glyphosate‐resistant Palmer amaranth (Amaranthus Palmeri S. Wats.) caused cotton growers to increase the use of preemergence (PRE) herbicides. These herbicides can cause crop injury, which increases the susceptibility window of cotton to thrips (Thysanoptera: Thripidae).
