Baseline Sensitivity of Nebraska Waterhemp and Palmer Amaranth to Dicamba and 2,4‐D

Agronomy Journal, 2016
The development of dicamba (3,6‐dichloro‐2‐methoxybenzoic acid)‐ and 2,4‐D [(2,4‐dichlorophenoxy) acetic acid]‐resistant soybean [Glycine max (L.) Merr.] will increase the frequency of applying these herbicides to control broadleaf weeds in soybean production systems. We evaluated the sensitivity of randomly selected waterhemp [Amaranthus tuberculatus (

A Survey of Glyphosate-Resistant Waterhemp (Amaranthus rudis) in Missouri Soybean Fields and Prediction of Glyphosate Resistance in Future Waterhemp Populations Based on In-Field Observations and Management Practices

Weed Technology, 2013
A survey of soybean fields containing waterhemp infestations was conducted just prior to harvest in 2008 and 2009 to determine the frequency and distribution of glyphosate-resistant waterhemp in Missouri, and to determine if there are any in-field parameters that may serve as indicators of glyphosate resistance in this species in future crop production

Sampling the Waterhemp (Amaranthus tuberculatus) Genome Using Pyrosequencing Technology

Weed Science, 2009
Recent advances in sequencing technologies (next-generation sequencing) offer dramatically increased sequencing throughput at a lower cost than traditional Sanger sequencing. This technology is changing genomics research by allowing large scale sequencing experiments in nonmodel systems.

Acetolactate Synthase Resistance in a Common Waterhemp (Amaranthus rudis) Population

Weed Technology, 1997
Research was initiated to determine (a) whether a common waterhemp population was resistant to acetolactate synthase (ALS) inhibiting herbicides, (b) the percentage of the population that was ALS-inhibitor resistant, (c) the resistance mechanism, and (d) the effectiveness of a whole plant assay to detect ALS-inhibitor resistance.

Imidazolinone and Sulfonylurea Resistance in a Biotype of Common Waterhemp (Amaranthus rudis)

Weed Science, 1996
The incidence of weed resistance to acetolactate synthase (ALS) inhibiting herbicides has increased in the United States. In 1993, a population of ALS-resistant common waterhemp was discovered after two confirmed applications of an imidazolinone herbicide.

Control of glyphosate-resistant waterhemp with preemergence herbicides in glyphosate- and dicamba-resistant soybean

Canadian Journal of Plant Science, 2019
Glyphosate-resistant (GR) waterhemp was first discovered in Ontario, Canada, in 2014. In Ontario, GR waterhemp interference in previous studies reduced soybean yield up to 73%. Tank-mixes of herbicides with multiple modes-of-action are important for delaying the evolution of herbicide resistance.

Glyphosate-Resistant Common Waterhemp (Amaranthus rudis) Confirmed in Texas

Weed Technology, 2011
Glyphosate-resistantAmaranthusspecies are a recognized risk to U.S. agriculture. With affected cropland exceeding 1.2 million ha, this epidemic is particularly pertinent to agricultural regions that utilize an intensive glyphosate-based management program to control weedy pests. Before 2006, Texas had no identified glyphosate-resistant populations. Two

Evaluating long-term and alternative control strategies for waterhemp (amaranthus tuberculatus) management

Waterhemp is a difficult to control weed in the Midwestern United States due to its prevalence in many cropping systems, its high fecundity, rapid growth rate, and evolution of herbicide resistance. Long-term and alternative control methods are vital to understand to allow for continued control of this weed.
