Baseline Sensitivity of Nebraska Waterhemp and Palmer Amaranth to Dicamba and 2,4‐D
Agronomy Journal, 2016The 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 (

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, 2009Recent 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.

Imidazolinone and Sulfonylurea Resistance in a Biotype of Common Waterhemp (Amaranthus rudis)
Weed Science, 1996The 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.

Glyphosate-Resistant Common Waterhemp (Amaranthus rudis) Confirmed in Texas
Weed Technology, 2011Glyphosate-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

Biology and control of common waterhemp (Amaranthus tuberculatus var. rudis)
Sixteen field experiments were conducted over a three-year period (2003--2005) at two Ontario locations to evaluate efficacy of pre-emergence and post-emergence herbicides for the control of waterhemp in corn and soybeans. The waterhemp biotype was resistant to both the acetolactate synthase inhibitors and photosystem II inhibitors at one location and ...openaire +1 more source
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.
