Filago pyramidata tolerant to ALS-Inhibiting herbicides: A new invasive weed in...
Palma-Bautista, Candelario; Vásquez-García, José; Domínguez-Valenzuela, José; Alcántara-de la Cruz, Ricardo; De Prado, Rafael; Portugal, JoãoWeeds that usually grow in non-agricultural areas have become increasingly common invading perennial crops. Species of the genus Filago, in addition to invading Spanish olive groves, have developed certain levels of natural tolerance to the acetolactate synthase (ALS) inhibiting herbicide flazasulfuron. The objective of this study was to determine the level and the mechanism involved in the tolerance to flazasu...
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...
Convergent adaptation of multiple herbicide resistance to auxin mimics and ALS-...
Domínguez-Valenzuela, José; Palma-Bautista, Candelario; Vázquez-Garcia, José; Yanniccari, Marcos; Gigón, Ramón; Alcántara-de la Cruz, RicardoHerbicide-resistant weeds have been identified and recorded on every continent where croplands are available. Despite the diversity of weed communities, it is of interest how selection has led to the same consequences in distant regions. Brassica rapa is a widespread naturalized weed that is found throughout temperate North and South America, and it is a frequent weed among winter cereal crops in Argentina and ...
