First case of resistance to bispyribac-sodium in barnyardgrass (Echinochloa crus-galli) from Ecuador
Background Echinochloa crus-galli is a weed that has developed resistance to multiple herbicides. In Ecuador, the selection pressure caused by the continued use of the acetolactate synthase-inhibiting herbicide bispyribac-sodium would have favored the selection of resistant accessions. Objective The current study aimed to analyze the sensitivity to bispyribac-sodium of E. crus-galli populations collected in the province of Guayas, the main rice-growing region of Ecuador. Methods A total of 35 E. crus-galli populations were assessed. These were sprayed with bispyribac-sodium [...]
