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 ...

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

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.

Resistance to the herbicides haloxyfop and iodosulfuron is common in commercial ryegrass (Lolium) seed lines. [PDF]
Pest Manag SciEleven variety lines had resistance detected for iodosulfuron only, six to haloxyfop, and 28 to both herbicides. No seedlings were detected with resistance to glyphosate. Abstract Background Ryegrass (Lolium spp.) is a key forage providing a $14 billion contribution to New Zealand's gross domestic product (GDP). However, ryegrass can also act as a weed

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.

Amaranthus tuberculatus (Moq.) J.D. Sauer – a new alien pigweed species in Croatia
BioInvasions Records, 2020 Amaranthus tuberculatus, commonly known as the rough-fruited water-hemp, is a dioecious annual weed species originating from North America. It has been introduced into Europe and Asia, where it is mostly considered a naturalized or casual alien occupying riparian areas, agricultural fields and disturbed habitats, especially in commercial port areas ...

Modeling the sustainability and economics of stacked herbicide-tolerant traits and early weed management strategy for waterhemp (Amaranthus tuberculatus) control [PDF]
, 2020 Diversity is key for sustainable weed management and can be achieved via both chemical and nonchemical control tactics. Genetically modified crops with two-way or three-way stacked herbicide-tolerant traits allow use of herbicide mixtures that would ...
