The objective of this work was to estimate the herbicide control action in sourgrass and mission grass, causing suppression in pre and post-emergence Congo grass. The experiment was developed at the Centro de Inovação Tecnologia GAPES, in the municipality of Rio Verde (GO). The experimental design was based on a randomized block with four replicates in the subdivided scheme, with nine treatments for pre-emergence, with one control with absence of application, and the others consisting in S-metolachlor (960 g ha), S-metolachlor (1152 g ha), S-metolachlor (1440 g ha), atrazine (400 g ha), atrazine (800 g ha), atrazine (1200 g ha), tembotrione (84 g ha), and mesotrione (120 g ha ). For post-emergence, one control with absence of application was employed, as well as mesotrione, tembotrione, nicosulfuron, nicosulfuron + mesotrione, nicosulfuron + tembotrione, terbuthylazine + mesotrione, mesotrione + atrazine, tembotrione + atrazine, nicosulfuron + atrazine, nicosulfuron + mesotrione + atrazine, nicosulfuron + tembotrione + atrazine and atrazine in two doses, applied in sourgrass, mission grass and Congo grass. The herbicides were applied in pre-emergence on weed sowing, while in the post-emergence period they were employed when sourgrass presented 2 to 3 tillers, mission grass presented 4 to 5 tillers and Congo grass 6 to 8 tillers. Treatments containing Smetolachlor were shown to consist the best control for mission grass and sourgrass in pre-emergence. S-metolachlor se was efficient in the control of B. ruziziensis and was therefore not indicated in the management of the intercrop. The herbicide mesotrione (or the mesotrione + atazine mixture) presented better control for sourgrass during post-emergence. The mixtures containing Nicosulfuron presented better control for mission grass during post-emergence.
