Resistance to PPO‐inhibiting herbicide in Palmer amaranth from Arkansas [PDF]

Pest Management Science, 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 ...

Integrated Palmer Amaranth Management in Glufosinate-Resistant Cotton: II. Primary, Secondary and Conservation Tillage

Agronomy, 2013
A three year field experiment was conducted to evaluate the role of soil inversion, cover crops and spring tillage methods for Palmer amaranth between-row (BR) and within-row (WR) management in glufosinate-resistant cotton.

Glyphosate-resistant Palmer amaranth: A threat to conservation tillage [PDF]

Journal of Soil and Water Conservation, 2011
Conservation tillage reduces the physical movement of soil to the minimum required for crop establishment and production. When consistently practiced as a soil and crop man- agement system, it greatly reduces soil erosion and is recognized for the potential to improve soil quality and water conservation and plant available water.

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 ...

Utility of roller wiper applications of dicamba for Palmer amaranth control in soybean

Pest Management Science, 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.

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 ...

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

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 ...

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.

Evolutionary framework and tribal circumscription of Amaranthaceae sensu stricto based on a comprehensive phylogenomic analysis

Cladistics, EarlyView.
Abstract The evolutionary history of Amaranthaceae sensu stricto (s.s.) has been shaped by multiple whole‐genome duplications and rapid radiations, producing an ecologically diverse lineage whose internal relationships have long remained unresolved.
