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. ... -
¿Cuánto paga una maleza por ser resistente a un herbicida?
(2015-08)La resistencia a herbicidas suele tener un costo energético para las malezas. Esto se traduce en una menor producción de semillas comparado a las plantas susceptibles. El conocimiento de estos aspectos ecológicos permite ... -
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 ... -
Estrategias de manejo y control de Rama Negra en sistemas de producción
(2013-05)Esta maleza se ha convertido en un serio problema para la producción de nuestra zona y gran parte de la región agrícola de nuestro país. Conocerla y actuar en momentos adecuados es la estrategia que se debe tener en cuenta ... -
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 ... -
Herbicide-resistant weeds from dryland agriculture in Argentina
(Wiley, 2024-01)We reviewed and performed a quantitative synthesis on herbicide-resistant weeds from rain-fed crops in Argentina. Twenty-four weed species distributed in the main extensive crops (soybean, maize, wheat, barley, oilseed ... -
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 ... -
Las malezas se defienden: resistencia a múltiples herbicidas
(2017-04)A nivel mundial, en la última década el número de malezas resistentes a más de un herbicida se ha incrementado en un 75 %. En nuestra región, el ryegrass no se queda atrás y cada vez es más frecuente la resistencia a varios ... -
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 ... -
Sensibilidad diferencial de cultivares de avena a residuos de herbicidas inhibidores de la ALS/AHAS
(Universidad Nacional de La Pampa, 2021-04-01)La avena (Avena sativa L.) es una de las especies con mayor importancia como recurso forrajero en la región semiárida pampeana. Comparado al resto de la región pampeana, la región semiárida presenta particulares condiciones ...
