The incidence of weeds in the garlic crop inter-feres with the quality and quantity of the harvest. This study aimed to evaluate the efficiency of herbicides in different com-binations of sequential applications during the cultivation of garlic. The experiment was carried out in a randomized block design, with ten treatments and four replications. The treat-ments consisted of sequential applications of the herbicides pendimethalin, pyroxasulfone/flumioxazin, ioxynil, and pen-dimethalin. The doses of Herbadox® (pendimethalin) were 4.0 l•ha-1, Totril® (ioxynil) 1.5 l•ha-1, and Kyojin® (pyroxasulfone/flumioxazin) 0.15 l•ha-1. Treatments consisted of sequential ap-plications of herbicide combinations. Applications were per-formed 7, 58, 97, and 128 days after planting. Phytotoxicity on the crop, efficacy in weed control, bulb classification, and pro-ductivity were evaluated. The results were submitted to ANO-VA, and the means were compared by the Scott-Knott test. The sequential application of pyroxasulfone/flumioxazin at 7 days after planting (DAP), ioxynil at 58 DAP, pendimethalin at 97 DAP, and pyroxasulfone/flumioxazin at 128 DAP (T7) stood out (96–100 % control of weeds, average productivity of 11.42 t·ha-1), which presented the best results relative to phytotoxicity, weed control, bulb classification, and crop productivity
