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 ... -
IMI resistance associated to crop-weed hybridization in a natural Brassica rapa population: characterization and fate
(2017-03)Wild turnip (Brassica rapa) is a common weed and a close relative to oilseed rape (Brassica napus). The Clearfield® production system is a highly adopted tool which provides an alternative solution for weed management, but ... -
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 ... -
Introgression from local cultivars is a driver of agricultural adaptation in Argentinian weedy rice
(Wiley, 2024-04-27)Weedy rice, a pervasive and troublesome weed found across the globe, has often evolved through fertilization of rice cultivars with little importance of crop-weed gene flow. In Argentina, weedy rice has been reported as ... -
Isolation and characterization of a new imidazolinone tolerant mutant in cotton
(Wiley, 2022-07)Cotton cultivars resistant to different herbicides have generated important advances in crop management. There is a wide range of cotton resistance to herbicides, however, commercial imidazolinone (IMI)-tolerant cultivars ... -
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 ... -
Manejo de malezas en los sistemas agriculturizados
(2014-12)Cada sistema tiene sus problemas y en función de ello hay que trabajarlos y sobre todo estudiarlos, teniendo en cuenta siempre el contexto que se producen. En nuestro país y el resto de América, el problema de las malezas ... -
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 ... -
Multiple-Herbicide resistance in a 2,4-D–Resistant waterhemp (Amaranthus tuberculatus) population from Nebraska
(Cambridge University Press; Weed Science Society of America, 2017-11)A 2,4-D-resistant tall waterhemp population (FS) from Nebraska was evaluated for resistance to other TIR1 auxin receptor herbicides and to herbicides having alternative mechanisms of action using greenhouse bioassays and ... -
Poblaciones de Lolium sp resistentes a cletodim en el sur de Buenos Aires
(Asociación Argentina de Ciencia de las Malezas (ASACIM), 2020-06)En la Argentina la resistencia de Lolium sp. a glifosato se ha comprobado desde hace tiempo, como también a otros herbicidas. Relevamientos previos indicarían que también se manifiesta la resistencia a cletodim. El objetivo ... -
Sensibilidad diferencial a 2,4-D de una población de Hirschfeldia incana (l.) Resistente a metsulfuron-metil en el SO de buenos aires. Argentina
(Asociación Latinoamericana de Malezas (ALAM), 2017)Se evaluó durante tres años la sensibilidad de una población de Hirschfeldia incana (CF) resistente a Metsulfuron y sospechosa de ser resistente a 2,4D en el SO de la provincia de Buenos Aires. Los resultados de % de control ... -
Stress response and detoxification mechanisms involved in non-target-site herbicide resistance in sunflower
(Wiley, 2020-08)The nature of non-target-site herbicide resistance (NTSR) to imidazolinone (IMI) in HA425 sunflower (Helianthus annuus L.) has not yet been fully characterized but could be related to xenobiotic metabolism. The objective ... -
Target-site and non-target-site resistance mechanisms confer multiple resistance to glyphosate and 2,4-D in Carduus acanthoides
(Elsevier, 2023-04)Carduus acanthoides L. is mainly a range-land weed, but in the 2010s has begun to invade GM crop production systems in Córdoba (Argentina), where glyphosate and 2,4-D have been commonly applied. In 2020, C. acanthoides was ... -
Tolerance of Pedunculate oak (Quercus robur) saplings to herbicides
(Ediciones INTA, 2020-12)Spraying herbicides to reduce weed competition is a usual practice in agricultural regions. However, tree tending under agroforestry or forest plantations is hampered by the extensive use of these pesticides. Here, we ... -
Transgene escape and persistence in an agroecosystem: the case of glyphosate-resistant Brassica rapa L. in central Argentina
(2018-03)Brassica rapa L. is an annual Brassicaceae species cultivated for oil and food production, whose wild form is a weed of crops worldwide. In temperate regions of South America and especially in the Argentine Pampas region, ... -
Transgenic glyphosate-resistant oilseed rape (Brassica napus) as an invasive weed in Argentina: detection, characterization, and control alternatives
(2016-12)The presence of glyphosate-resistant oilseed rape populations in Argentina was detected and characterized. The resistant plants were found as weeds in RR soybeans and other fields. The immunological and molecular analysis ...
