Combined effects of canola plant density and insecticide management strategies on flea beetle abundance, canola defoliation, and yield across the Canadian prairies

Pest Management Science, EarlyView.
Increasing canola plant density reduced flea beetle abundance per plant and increased yield, independent of region or insecticide use, highlighting its potential as a component of integrated pest management. Abstract The crucifer flea beetle, Phyllotreta cruciferae (Goeze), and the striped flea beetle, Phyllotreta striolata (Fabricius) (Coleoptera ...

Targeted herbicide spraying systems: role of nozzle type, number of nozzle activation, nozzle orientation, and boom height on spray coverage and weed control

Pest Management Science, EarlyView.
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

Pest Management Science, EarlyView.
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 ...

Review of genotoxicity studies of glyphosate and glyphosate-based formulations [PDF]

Critical Reviews in Toxicology, 2013
An earlier review of the toxicity of glyphosate and the original Roundup™-branded formulation concluded that neither glyphosate nor the formulation poses a risk for the production of heritable/somatic mutations in humans. The present review of subsequent genotoxicity publications and regulatory studies of glyphosate and glyphosate-based formulations ...

Toxicity of aqueous extracts of Ilex paraguariensis A.St.‐Hil. about Euphorbia heterophylla L.

Pest Management Science, EarlyView.
Aqueous extracts of Ilex paraguariensis A.St.‐Hil. strongly inhibit Euphorbia heterophylla L. germination and early seedling growth, but show mild phytotoxicity on mature plants, paradoxically promoting biomass via antioxidants. Abstract BACKGROUND The escalating challenge of herbicide‐resistant weeds, exemplified by Euphorbia heterophylla L.

Overexpression of G10-EPSPS in soybean provides high glyphosate tolerance

Journal of Integrative Agriculture, 2019
Glyphosate is a highly efficient, broad-spectrum nonspecific herbicide that inhibits the 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS)-mediated pathway of shikimic acid.

Integrated genomic and transcriptomic approaches reveal oxidative stress adaptation mechanisms in a mesotrione‐resistant Amaranthus tuberculatus biotype

Pest Management Science, EarlyView.
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,

Glyphosate

, 2018
Glyphosate is the most widely used herbicide in the world. Globally, 6.1 billion kilograms have been applied in the last decade alone. In 2015, the International Agency for Research on Cancer (IARC), classified glyphosate as ‘probably carcinogenic to humans’.
