Impact of cover crops on furrow-irrigated rice and Palmer amaranth (Amaranthus palmeri) emergence

Weed Technology
As mid-southern U.S. rice producers continue to adopt furrow-irrigated rice production practices, supplementary management efforts will be vital in combating Palmer amaranth due to the extended germination period provided by the lack of a continual flood.

The Vulnerability of New Zealand Forage Plants to Incursions by New Pests, Pathogens and Weeds, and the Case for Greater Protection

New Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
We outline the diversity of pests, weeds and plant pathogens absent from New Zealand that threaten forage production, examine their potential import pathways, and outline the challenges of managing them should they arrive. The number and diversity of threats and pathways indicates ongoing incursions are inevitable.

Integrated effect of row spacing and herbicide programs on photosynthetically active radiation, control, and seed production of multiple herbicide‐resistant Palmer amaranth in corn

Agrosystems, Geosciences & Environment
Multiple herbicide‐resistant (MHR) Palmer amaranth has been ranked as the most problematic weed in row crop fields in Nebraska. Integration of narrow row spacing with herbicide might augment control of MHR Palmer amaranth.

Glyphosate- and atrazine-resistant Palmer amaranth in New York: Confirmation and Management with Alternative Postemergence Herbicides

Weed Technology
Palmer amaranth is an increasing concern for producers in the northeastern United States. A new Palmer amaranth population (NY_PA) was identified in a soybean field in Ontario County, New York, in 2024.

Efficacy of isoxaflutole when used preplant incorporated or preemergence

Weed Technology
Palmer amaranth is a summer annual weed native to the southwestern United States and is particularly troublesome across the Cotton Belt. The use of soil-residual herbicides is crucial for cotton producers in the Texas High Plains attempting to achieve ...

Emergence Date Influences Growth and Fecundity of Palmer Amaranth in Cotton

Journal of Cotton Science, 2016
Research was conducted in 2012 and 2013 in Fayetteville, AR to evaluate the impact of Palmer amaranth (Amaranthus palmeri (S.) Wats.) emergence date on plant biomass, height, and seed production as well as the corresponding influence on cotton (Gossypium hirsutum L.) biomass and yield. Palmer amaranth was evaluated in the presence and absence of cotton

Confirmation and management of atrazine-resistant Palmer amaranth (Amaranthus palmeri) in North Carolina

Weed Technology
North Carolina farmers rely extensively on applying atrazine to their corn crops to achieve effective control of Palmer amaranth. In 2016, a farmer in Washington County, North Carolina, reported a failure of atrazine to control Palmer amaranth in a corn ...

Influence of Carrier Volume and Nozzle Selection on Palmer Amaranth Control

Peanut Science, 2014
ABSTRACT Palmer amaranth is one of the most troublesome weeds in the southeast. Effective control is essential in order to avoid reductions of crop yield. Due to widespread resistance to acetolactate synthase (ALS)-inhibiting herbicides, postemergence contact herbicides are often the only in-season option to control Palmer amaranth in ...

Full-season herbicide programs to control a seven-way-resistant Palmer amaranth accession under soybean technologies

Weed Technology
A seven-way herbicide-resistant Palmer amaranth accession (MSR2) was identified in AR. Herbicide programs providing season-long control of this problematic accession need to be investigated, especially within the current soybean portfolio.
