Inheritance of 2,4-dichlorophenoxyacetic acid (2,4-D) resistance in Amaranthus palmeri. [PDF]

Sci Rep, 2022
AbstractIn this study, the inheritance of 2,4-D resistance in a multiple herbicide-resistant Palmer amaranth (KCTR) was investigated. Direct and reciprocal crosses were performed using 2,4-D-resistant KCTR and susceptible KSS plants to generate F1 progenies.

Introduction and management of Amaranthus palmeri in Brazil

Advances in Weed Science, 2023
Abstract Glyphosate-resistant palmer amaranth, Amaranthus palmeri, a difficult to control weed with aggressive growth, capable of causing large yield losses in annual crops, was identified in Brazil, in the state of Mato Grosso, in 2015. After notification, an epidemiological survey was carried out to identify the place of entry and area of dispersion.

Growth Analysis of Glyphosate-Resistant and Susceptible Amaranthus palmeri Biotypes. [PDF]

Plant Environ Interact
ABSTRACTThis study examined the growth parameters of both glyphosate‐susceptible and glyphosate‐resistant biotypes of Amaranthus palmeri, designated as GA2005 and GA2017, respectively. A two‐year microplot field study was conducted to assess their growth characteristics.

Gene amplification confers glyphosate resistance in Amaranthus palmeri [PDF]

Proceedings of the National Academy of Sciences, 2009
The herbicide glyphosate became widely used in the United States and other parts of the world after the commercialization of glyphosate-resistant crops. These crops have constitutive overexpression of a glyphosate-insensitive form of the herbicide target site gene, 5-enolpyruvylshikimate-3-phosphate synthase ( EPSPS
