Interference of Selected Palmer Amaranth (Amaranthus palmeri) Biotypes in Soybean (Glycine max)

International Journal of Agronomy, 2012
Palmer amaranth (Amaranthus palmeri S. Wats.) has become difficult to control in row crops due to selection for biotypes that are no longer controlled by acetolactate synthase inhibiting herbicides and/or glyphosate. Early season interference in soybean [

Palmer amaranth control in furrow-irrigated rice with florpyrauxifen-benzyl

Weed Technology, 2022
AbstractPalmer amaranth is a common weed on levees in rice fields but has become increasingly problematic with the adoption of furrow-irrigated rice and lack of an established flood. Florpyrauxifen-benzyl previously has been found effective for controlling Palmer amaranth in rice, but the efficacy of low rates of florpyrauxifen-benzyl and the effect of

Corn tolerance and weed control with amicarbazone and metribuzin applied preemergence

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Since the late 1950s, atrazine has been a cornerstone of corn (Zea mays L.) weed control, but decades of use have raised concerns about groundwater contamination and enhanced biodegradation. Therefore, amicarbazone and metribuzin were evaluated as alternatives to preemergence use of atrazine in corn.

Sorghum tolerance and weed control with amicarbazone and metribuzin applied preemergence

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Groundwater contamination has prompted the Environmental Protection Agency to consider restricting atrazine use, highlighting the need for alternative preemergence herbicides in grain sorghum (Sorghum Moench). Research was conducted in 2023 and 2024 to evaluate grain sorghum tolerance and weed control from preemergence applications of ...

Analysis of glutamine synthetase target‐site mutations and their role in endowing glufosinate‐ammonium resistance

Pest Management Science, Volume 82, Issue 8, Page 7633-7644, August 2026.
GS2.2 G255D mutation conferred enzyme‐level glufosinate insensitivity but no whole‐plant resistance, showing trade‐offs between catalytic function and herbicide binding and providing a baseline for future studies on target‐site glufosinate resistance.

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,

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.

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.

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.

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.
