Carfentrazone-ethyl resistance in an Amaranthus tuberculatus population is not mediated by amino acid alterations in the PPO2 protein. [PDF]
PLoS ONE, 2019 To date, the only known mechanism conferring protoporphyrinogen IX oxidase (PPO)-inhibitor resistance in waterhemp (Amaranthus tuberculatus) is a glycine deletion in PPO2 (ΔG210), which results in cross-resistance to foliar PPO-inhibiting herbicides ...

Integrated genomic and transcriptomic approaches reveal oxidative stress adaptation mechanisms in a mesotrione-resistant Amaranthus tuberculatus biotype. [PDF]
Pest Manag SciIntegrated GWAS and transcriptomics in a Canadian waterhemp biotype reveal mesotrione resistance is polygenic and metabolically driven. Significant SNPs and 187 herbicide‐responsive genes point to enhanced redox homeostasis, glutathione‐linked detoxification, lipid/secondary metabolism, and oxidative stress responses. Resistance arises from coordinated,

Targeted herbicide spraying systems: role of nozzle type, number of nozzle activation, nozzle orientation, and boom height on spray coverage and weed control. [PDF]
Pest Manag SciTargeted herbicide application technology performance depends on sprayer configuration. Across five studies, activation of multiple, overlapping nozzles and maintaining appropriate boom height consistently improved spray coverage and weed control, highlighting the importance of optimized sprayer setup for effective and reliable weed control.

Target-site and non-target-site mechanisms confer multiple herbicide resistance in waterhemp (Amaranthus tuberculatus) accessions from Wisconsin. [PDF]
Pest Manag SciThe A101 accession is the first confirmed case of hydroxyphenyl pyruvate dioxygenase resistance in Amaranthus tuberculatus in Wisconsin, and the first report of P450s associated with atrazine resistance in A. tuberculatus globally. Abstract BACKGROUND A preliminary screening identified a multiple herbicide‐resistant waterhemp, Amaranthus tuberculatus ...

Non-triazine photosystem II inhibitors provide effective control of metabolic atrazine-resistant Amaranthus tuberculatus. [PDF]
Pest Manag SciMetabolism‐based atrazine‐resistant Amaranthus tuberculatus populations ACR and MCR exhibit little or no cross‐resistance to amicarbazone and metribuzin, suggesting that non‐halogenated Group 5 herbicides can be utilized to re‐establish effective control.

Control and Distribution of Herbicide Resistant Waterhemp (Amaranthus tuberculatus) in Ontario [PDF]
, 2019 Field surveys were conducted in 2016, 2017 and 2018 to build on previous distribution research. Waterhemp was located at 42 additional locations in seven Ontario counties and the province of Quebec.

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)

Changing landscape of waterhemp herbicide resistance in Wisconsin: a comparative analysis over time
Weed TechnologyA comprehensive assessment of herbicide resistance in waterhemp accessions to herbicides commonly used on corn and soybean over time is crucially necessary for documenting shifts in herbicide resistance patterns and identifying effective management ...

The evolution of separate sexes in waterhemp is associated with surprising chromosomal diversity and complexity. [PDF]
PLoS BiolThe evolution of separate sexes is hypothesized to occur through distinct pathways involving few large-effect or many small-effect alleles. However, we lack empirical evidence for how these different genetic architectures shape the transition from quantitative variation in sex expression to distinct male and female phenotypes.
