Determination of the Mechanisms of MCPA Resistance in <i>Amaranthus powellii</i>. [PDF]

Plant Direct
ABSTRACT Resistance to 2‐methyl‐4‐chloro‐phenoxyacetic acid (MCPA) was recently confirmed in a population of green pigweed (Amaranthus powellii) from Dresden, Ontario, Canada, with a resistance factor of 4.4. Resistance to synthetic auxin herbicides in Amaranthus species has previously been linked to non‐target site resistance mechanisms with low‐level

Distinct Detoxification Mechanisms Confer Resistance to Mesotrione and Atrazine in a Population of Waterhemp       [PDF]

Plant Physiology, 2013
Abstract Previous research reported the first case of resistance to mesotrione and other 4-hydroxyphenylpyruvate dioxygenase (HPPD) herbicides in a waterhemp (Amaranthus tuberculatus) population designated MCR (for McLean County mesotrione- and atrazine-resistant).

Gene Duplication and Aneuploidy Trigger Rapid Evolution of Herbicide Resistance in Common Waterhemp [PDF]

Plant Physiology, 2018
An increase in gene copy number is often associated with changes in the number and structure of chromosomes, as has been widely observed in yeast and eukaryotic tumors, yet little is known about stress-induced chromosomal changes in plants. Previously, we reported that the EPSPS (5-enolpyruvylshikimate-3-phosphate synthase) gene, the molecular target ...

Influence of Postemergence Dicamba/Glyphosate Timing and Inclusion of Acetochlor as a Layered Residual on Weed Control and Soybean Yield

Frontiers in Agronomy, 2021
Roundup Ready 2 Xtend® [glyphosate- and dicamba-resistant (DR)] soybean is a novel trait option for postemergence (POST) control of herbicide-resistant broadleaf weeds in soybean.

Influence of Broadcast Nozzle Design and Weed Density on Dicamba Plus Glyphosate Deposition, Coverage, and Efficacy in Dicamba-Resistant Soybean

Frontiers in Agronomy, 2022
Dicamba injury to sensitive soybean and other broadleaf crops due to drift is a major issue. Dicamba label restrictions have been created to mitigate the off-target movement of dicamba.

Management Options and Factors Affecting Control of a Common Waterhemp (Amaranthus rudis) Biotype Resistant to Protoporphyrinogen Oxidase-Inhibiting Herbicides

International Journal of Agronomy, 2012
Repeated use of protox-inhibiting herbicides has resulted in a common waterhemp (Amaranthus rudis Sauer) biotype that survived lactofen applied up to 10 times the labeled rate.

Layered‐residual herbicide programs for waterhemp control in glufosinate‐resistant soybean

Crop, Forage & Turfgrass Management, 2023
Core Ideas Glufosinate is an important POST herbicide for waterhemp control in glufosinate‐resistant soybean. The layered‐residual herbicide approach improved season‐long waterhemp control. Glufosinate POST combined with layered soil residual herbicides improved season‐long waterhemp control.
