Glyphosate Resistance Affect the Physiological Quality of Conyza bonariensis seeds [PDF]

Planta Daninha, 2019
: High seed production and dispersal capacity and glyphosate resistance are among the main factors that have made hairy fleabane (Conyza bonariensis) one of the most important and dispersed weeds in the world.

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.

A hydrothermal seedling emergence model for Conyza bonariensis

Weed Research, 2013
SummaryConyza bonariensis is a South American native annual Asteraceae that has been introduced to the Mediterranean, where it behaves as a ruderal plant and a weed that is difficult to control in several crops. The development of predictive models can contribute to control measures at early growth stages, but currently there are no studies to predict ...

Thirty years of glyphosate‐resistant crops and weeds: Current situation and future prospects

Pest Management Science, EarlyView.
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

Inundation Duration Shapes Germination of Native and Non‐Native Plant Assemblages From Floodplain Soil Seedbanks

Ecohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Episodic inundation regulates germination and recruitment from soil seedbanks, which are key processes driving vegetation dynamics in dryland floodplains. In the Murray‐Darling Basin, extensive floodplain modification and flow regulation have altered flow regimes so that anthropogenically controlled environmental watering is often required to ...
