Late-season surveys to document seed rain potential of Palmer amaranth (Amaranthus palmeri) and waterhemp (Amaranthus tuberculatus) in Texas cotton. [PDF]
PLoS ONE, 2020 Weed escapes are often present in large production fields prior to harvest, contributing to seed rain and species persistence. Late-season surveys were conducted in cotton (Gossypium hirsutum L.) fields in Texas in 2016 and 2017 to identify common weed ...

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,

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 ...
