Two experiments were conducted simultaneously with the objective of evaluating the selectivity of nicosulfuron and chlorimuron-ethyl herbicides, applied in post-emergence at two developmental stages in alfalfa crop. Trials were conducted in greenhouse conditions in randomized entirely design, with five replications, in a 4 x 2 factorial scheme. The factors corresponded to the application of chlorimuron-ethyl herbicide at 0, 7.5, 15 and 30 g ha-1 (Trial 1) and nicosulfuron at doses of 0, 20, 40 and 80 g ha-1 (Trial 2). Herbicides were sprayed in plants with four and seven fully expanded leaves, corresponding to stages 1 and 2, respectively. Phytotoxicity evaluations were assessed at 7 and 21 days after treatment application (DAA) and of plan...
