A novel EPSPS Pro-106-His mutation confers the first case of glyphosate resistance in Digitaria sanguinalis
(Wiley, 2022-04)BACKGROUND: Digitaria sanguinalis has been identified as a species at high risk of evolving herbicide resistance, but thus far, there are no records of resistance to glyphosate. This species is one of the most common weeds ... -
Comparison of premix glyphosate and 2,4-D formulation and direct tank mixture for control of Conyza canadensis and Epilobium ciliatum
(Elsevier, 2021-07)Premix or tank mix of glyphosate and 2,4-D are a good alternative to control glyphosate-resistant and -tolerant weeds; however, the combination of herbicides may increase the environmental impacts, since mixtures often ... -
Comparison of Sensitivity to Glyphosate of Euphorbia davidii Populations = Comparação da Sensibilidade ao Glyphosate de Populações de Euphorbia davidii
(2018)Euphorbia davidii (Euphorbiaceae) is a summer annual weed present in the Province of Buenos Aires, Argentina. The aim of this study was to compare the sensitivity to glyphosate of different populations of Euphorbia davidii. ... -
Constitutive overexpression of EPSPS by gene duplication is involved in glyphosate resistance in Salsola tragus
(Wiley, 2022-11)Background: Glyphosate-resistant Salsola tragus accessions have been identified in the USA and Argentina; however, the mechanisms of glyphosate resistance have not been elucidated. The goal of this study was to determine ... -
Developing a glyphosate-bioremediation strategy using plants and actinobacteria: potential improvement of a riparian environment
(Elsevier, 2022-12)Glyphosate (Gly) and its principal degradation product, the aminomethylphosphonic acid (AMPA) were found in soils from a riparian environment in Argentina. Sixty-five actinobacteria were isolated from these soils, rhizosphere, ... -
Dynamics of glyphosate resistance in Lolium perenne: pollen-mediated gene flow under field conditions in Argentina
(MDPI, 2018-11)The genus Lolium has shown a high tendency to evolve resistance to herbicides. Considering the high level of allogamy of L. perenne and the importance of the wind as an agent for pollen dispersion, the aim of this work was ... -
Efecto del glifosato sobre el crecimiento y acumulación de azúcares libres en dos biotipos de lolium perenne de distinta sensibilidad al herbicida = Glyphosate effects on the growth and free sugar accumulation of two lolium perenn e biotypes with different herbicide sensitivity
(Sociedade Brasileira da Ciência das Plantas Daninhas, 2012-03)El movimiento sistémico del glifosato está determinado por el transporte de fotoasimilados. A su vez, la capacidad de un destino de consumir los asimilados está condicionada por su actividad metabólica. Pese a su importancia, ... -
Effects of glyphosate on the movement of assimilates of two Lolium perenne L. populations with differential herbicide sensitivity
(2012-10)Glyphosate applications trigger the depletion of aromatic amino acid pools and the decrease of photosynthesis that results in changes in carbon metabolism. The aim of this work was to determine the effect of glyphosate on ... -
Glyphosate and nutrient retention in preferential flow pathways
(Asociación Argentina de Ecología, 2019-12)Riparian vegetation strips (RVS) reduce surface runoff volume and retain sediments, pesticides and nutrients that are transported across them from adjacent crop-fields (CF). The ability of these strips to retain glyphosate ... -
Glyphosate effects on gas exchange and chlorophyll fluorescence responses of two Lolium perenne L. biotypes with differential herbicide sensitivity
(2012-08)Despite the extensive use of glyphosate, how it alters the physiology and metabolism of plants is still unclear. Photosynthesis is not regarded to be a primary inhibitory target of glyphosate, but it has been reported to ... -
Glyphosate resistance in perennial ryegrass (Lolium perenne L.) from Argentina
(2012-02)In Argentina, glyphosate is the most widely used herbicide. A population of perennial ryegrass, subjected to two glyphosate applications per year during twelve years, was putatively identified as glyphosate-resistant based ... -
Glyphosate retention in grassland riparian areas is reduced by the invasion of exotic trees = La retención de glifosato en las áreas ribereñas con pastizales se reduce por la invasión de árboles exóticos
(Fundación Rómulo Raggio, 2016)In this study, we examined some aspects regarding the effect of willow trees (Salix fragilis L.) invasion of grassland riparian environments in the Argentinean Pampas on the runoff reduction, sedimentation and glyphosate ... -
Inheritance of glyphosate resistance in Lolium perenne and hybrids with Lolium multiflorum
(2015-05)Glyphosate-resistant Lolium species have been selected in weed communities where glyphosate is the herbicide used almost exclusively for weed control. The rate of evolution of herbicide resistance is highly influenced by ... -
Mechanism of Resistance to Glyphosate in Lolium perenne from Argentina
(2017-10)In Argentina, glyphosate resistance was reported in a Lolium perenne population after 12 years of successful herbicide use. The aim of the current paper was to put in evidence for the mechanism of glyphosate resistance of ...
