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 efficacy of any pesticide is an exhaustible resource that can be depleted over time. For
decades, the dominant paradigm–that weed mobility is low relative to insect pests and …

BACKGROUND The widespread occurrence of ALS inhibitor‐and glyphosate‐resistant
Amaranthus palmeri has led to increasing use of protoporphyrinogen oxidase (PPO) …

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; …

This research was aimed at understanding how far and how fast glyphosate-resistant (GR)
Palmer amaranth will spread in cotton and the consequences associated with allowing a …

Abstract Amaranthus palmeri S. Watson (Palmer amaranth) is an invasive agricultural weed
that has quickly risen from a state of relative obscurity to now being globally regarded as one …

Two of the most problematic Amaranthus species in soybean production today are tall
waterhemp and Palmer amaranth. This study determined the percentage of tall waterhemp …

The management of glyphosate-resistant Palmer amaranth has been a challenge in
southern United States crop** systems. Registration of dicamba-resistant crops will …

Palmer amaranth has evolved target and nontarget site resistance to protoporphyrinogen
oxidase-inhibitor herbicides in the United States. Recently, a population (KCTR) from a long …

Gene flow is an important component in evolutionary biology; however, the role of gene flow
in dispersal of herbicide-resistant alleles among weed populations is poorly understood …
