ABSTRACT The present research work was installed in Santa Elena, Virú, La Libertad (Latitude -8.46657, Longitude -78.8830), in order to investigate the efficiency of three post-emergent herbicides for weed control in Cynara scolymus L., var. Imperial condor. The treatments studied consisted of three herbicides (Oxifluorfen 250 ml / ha, Linuron 500 ml / ha, Clethodim 700 ml / ha and the absolute control without applying). Using Random Complete Block Design (DBCA). The variables were evaluated: number of live and dead weeds, phytotoxicity index and percentage of weed control at 10, 20 and 30 days; In the artichoke, the following were evaluated: plant height and diameter, number of live and dead leaves at 10, 20 and 30 days, respectively. All the defined variables were subjected to the analysis of variance, using the Tukey statistical test with 5% of mistake. The experimental results concluded that the herbicide Oxifluorfen with a dose of 250 l / ha presented the highest percentage of efficacy in weed control, while Clethodim at 0.70 l / ha the lowest weed control was observed. The treatments Oxifluorfen (0.25 l / ha), Linuron (0.50 l / ha), and Clethodim (or.70 l / ha), presented a moderate phytotoxicity effect. While the characteristics evaluated plant height and diameter and number of dead leaves in the artichoke crop according to the Tukey test did not show significance.
