Multiple-Herbicide Resistance Is Widespread in Roadside Palmer Amaranth Populations. [PDF]
PLoS ONE, 2016 Herbicide-resistant Palmer amaranth is a widespread issue in row-crop production in the Midsouthern US. Palmer amaranth is commonly found on roadside habitats in this region, but little is known on the degree of herbicide resistance in these populations.

Understanding Resistance Mechanisms to Trifluralin in an Arkansas Palmer Amaranth Population [PDF]
Genes, 2021 Amaranthus palmeri S. Watson (Palmer amaranth) is considered a problematic and troublesome weed species in many crops in the USA, partly because of its ability to evolve resistance to herbicides. In this study, we explored the mechanism of resistance in a trifluralin-resistant A. palmeri accession collected from Arkansas, USA.

Mechanism of Resistance to S-metolachlor in Palmer amaranth. [PDF]
Front Plant Sci, 2021 Herbicides are major tools for effective weed management. The evolution of resistance to herbicides in weedy species, especially contributed by non-target-site-based resistance (NTSR) is a worrisome issue in crop production globally. Glyphosate-resistant Palmer amaranth (Amaranthus palmeri) is one of the extremely difficult weeds in southern US crop ...

Predominance of Metabolic Resistance in a Six-Way-Resistant Palmer Amaranth (Amaranthus palmeri) Population [PDF]
Frontiers in Plant Science, 2021 Evolution of multiple herbicide resistance in Palmer amaranth across the United States is a serious challenge for its management. Recently, a Palmer amaranth population (KCTR; Kansas Conservation Tillage Resistant) from a long-term conservation tillage ...

Biological effects on Palmer amaranth surviving glufosinate
Agrosystems, Geosciences & Environment, 2022 Palmer amaranth (Amaranthus palmeri S. Watson) is a difficult weed to manage due to competitive growth, fecundity, and evolved herbicide resistance. Limited information exist on the fecundity of vegetative stage Palmer amaranth surviving glufosinate ...

Utility of roller wiper applications of dicamba for Palmer amaranth control in soybean. [PDF]
Pest Manag Sci, 2022 AbstractBACKGROUNDThe commercialization of dicamba‐resistant soybean has resulted in increased concern for off‐target movement of dicamba onto sensitive vegetation. To mitigate the off‐target movement through physical drift, one might consider use of rope wicks and other wiper applicators.

Resistance to PPO-inhibiting herbicide in Palmer amaranth from Arkansas. [PDF]
Pest Manag Sci, 2016 AbstractBACKGROUNDThe widespread occurrence of ALS inhibitor‐ and glyphosate‐resistant Amaranthus palmeri has led to increasing use of protoporphyrinogen oxidase (PPO)‐inhibiting herbicides in cotton and soybean. Studies were conducted to confirm resistance to fomesafen (a PPO inhibitor), determine the resistance frequency, examine the resistance ...

Palmer Amaranth (Amaranthus palmeri) Adaptation to US Midwest Agroecosystems
Frontiers in Agronomy, 2022 Palmer amaranth (Amaranthus palmeri S. 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 ...
