Metabolic Pathway of Topramezone in Multiple-Resistant Waterhemp (Amaranthus tuberculatus) Differs From Naturally Tolerant Maize [PDF]
Frontiers in Plant Science, 2018 Waterhemp [Amaranthus tuberculatus (Moq.) Sauer] is a problematic dicot weed in maize, soybean, and cotton production in the United States. Waterhemp has evolved resistance to several commercial herbicides that inhibit the 4-hydroxyphenylpyruvate ...

Managing herbicide‐resistant waterhemp (Amaranthus tuberculatus [Moq.] J.D. Sauer) seedbanks by integrating several management tactics [PDF]
Agrosystems, Geosciences & Environment, 2023 Herbicide‐resistant waterhemp (Amaranthus tuberculatus [Moq.] J.D. Sauer) continues to threaten the productivity of many US crops. Thus, integrating non‐herbicidal tactics with herbicides to reduce weed seedbanks is gaining popularity.

Growth and development of multiple waterhemp (Amaranthus tuberculatus) cohorts in corn and soybeans
Frontiers in Agronomy, 2022 Waterhemp is a troublesome weed species in cropping systems throughout Wisconsin and much of the US Midwest. Coupled with extended emergence window, rapid growth, high genetic diversity, and herbicide resistance to multiple sites of action, waterhemp ...

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 Management Science, Volume 82, Issue 6, Page 5216-5224, June 2026.Targeted 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 Management Science, Volume 82, Issue 6, Page 5695-5706, June 2026.The 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 Management Science, Volume 82, Issue 7, Page 6864-6876, July 2026.Metabolism‐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.

The evolution of separate sexes in waterhemp is associated with surprising chromosomal diversity and complexity [PDF]
PLOS BiologyThe 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.
