Palmer Amaranth (Amaranthus palmeri): A Review [PDF]

Weed Technology, 2013
In little over 20 yr, Palmer amaranth has risen from relative obscurity to its current status as one of the most widespread, troublesome, and economically damaging agronomic weeds in the southeastern U.S. Numerous factors have enabled Palmer amaranth to become such a dominant and difficult-to-control weed, including its rapid growth rate, high ...

Identification of Weed-Suppressive Tomato Cultivars for Weed Management

Plants, 2022
Weed-suppressive crop cultivars are a potentially attractive option in weed management strategies (IWM). A greenhouse study was conducted at the R. R. Foil Plant Science Research Center, Starkville, MS, to assess the potential weed-suppressive ability of

Quantification of palmer amaranth seed number using a computerized particle analyzer

Agricultural & Environmental Letters, 2020
We evaluated the accuracy of a computerized particle analyzer (CPA) for high‐throughput counting of Palmer amaranth (Amaranthus palmeri S. Watson) seeds and subsequently used the CPA to verify the accuracy of two subsampling methods for estimation of ...

Steaming soil is effective in eliminating invasive alien plants (IAPs) – part I: effect of exposure method

Pest Management Science, Volume 81, Issue 4, Page 2032-2039, April 2025.
As regulations on chemical pesticides become more stringent, it is likely that there will be interest in water steam as an alternative approach for soil disinfestation. This study investigated the feasibility of utilizing a soil steaming device for thermal control of selected invasive alien plants and showed a promising mortality rate for their ...

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,

Palmer amaranth (Amaranthus palmeri) control in furrow-irrigated rice with fluridone

Weed Technology
Herbicide-resistant Palmer amaranth is creating additional challenges for producers who choose to adopt a furrow-irrigated rice production system due to the absence of a sustained flood, enabling extended weed emergence.

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 [

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.
