Non-triazine photosystem II inhibitors provide effective control of metabolic atrazine-resistant Amaranthus tuberculatus. [PDF]

Pest Manag Sci
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.

Integrated genomic and transcriptomic approaches reveal oxidative stress adaptation mechanisms in a mesotrione-resistant Amaranthus tuberculatus biotype. [PDF]

Pest Manag Sci
Integrated 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 Sci
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 ...

Draft Genomes of Amaranthus tuberculatus, Amaranthus hybridus, and Amaranthus palmeri. [PDF]

Genome Biol Evol, 2020
Amaranthus tuberculatus, Amaranthus hybridus, and Amaranthus palmeri are agronomically important weed species. Here, we present the most contiguous draft assemblies of these three species to date.

RNAi technology development for weed control: all smoke and no fire? [PDF]

Pest Manag Sci
Despite the potential of Spray‐Induced Gene Silencing in weed management several critical points such as molecular target, weed species of interest as well as delivery techniques need to be addressed. Abstract RNA interference (RNAi) technology, specifically Spray‐Induced Gene Silencing (SIGS), holds potential as an innovative approach for selective ...

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 Sci
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.

Allelopathic Potential of Hemp: Implications for Integrated Weed Management

Frontiers in Agronomy, 2022
Evolved resistance to herbicides necessitates alternative weed control strategies. Allelopathic crops show promise as an alternative to exogenous herbicides and could be used to reduce establishment, growth, and reproduction of weeds.

Weed Community Composition in Simple and More Diverse Cropping Systems

Frontiers in Agronomy, 2022
Weed communities in three cropping systems suitable for the Midwestern USA were studied from 2017 to 2020 to examine how crop diversification and the intensity of herbicide use affected weed community diversity, stand density, and aboveground mass.

Functional synergy and genomic linkage of glyphosate resistance traits in Canada fleabane. [PDF]

Pest Manag Sci
Stacking target‐site and non‐target‐site glyphosate resistance mechanisms in Conyza canadensis results in strong synergistic effects. This study quantifies gene × gene interactions and maps linked resistance loci, advancing our understanding of herbicide resistance genetics and informing management strategies.
