Different non-target site mechanisms endow different glyphosate susceptibility ...
Vázquez-García, José; Torra, Joel; Palma-Bautista, Candelario; Bastida, Fernando; Alcántara-de la Cruz, Ricardo; Portugal, João; De Prado, RafaelIn recent decades, cereal agriculture across main producing areas in Spain has progressively adopted direct sowing, associated with an increased use of herbicides in pre-sowing. Weedy species from genus Avena have been observed after the application of glyphosate in wheat. Here, Avena fatua (two accessions), Avena byzantina and Avena sterilis subsp. sterilis, one accession each, were taxonomically characterized...
The Asp376Glu mutation and enhanced metabolism controlling the resistance of AL...
Domínguez-Valenzuela, José; Vázquez-García, José; Castro, Patricia; Palma-Bautista, Candelario; Cruz-Hipolito, Hugo; Rey, Maria-DoloresA study was carried out to determine the ALS (acetolactate synthase)-inhibitor herbicide resistance in the Mexican grass Ixophorus unisetus, a troublesome weed in corn crops in Mexico. First, the resistance was confirmed in field screening assays. Eight populations that survived nicosulfuron treatment at a field rate of 40 g ai ha−1 were labeled as putative-resistant. Dose–response trials demonstrated a high re...
Multiple herbicide resistance evolution: The case of eleusine indica in Brazil
Vázquez-García, José; Alcántara-de la Cruz, Ricardo; Rojano-Delgado, Antonia; Palma-Bautista, Candelario; De Prado, Rafael; Fernandes, JoãoThe occurrence of multiple herbicide resistant weeds has increased considerably in glyphosate-resistant soybean fields in Brazil; however, the mechanisms governing this resistance have not been studied. In its study, the target-site and nontarget-site mechanisms were characterized in an Eleusine indica population (R-15) with multiple resistance to the acetyl-CoA carboxylase (ACCase) inhibitors, glyphosate, imaz...
