The present invention relates to a combination herbicide comprising: a.The herbicide that is 2 - chloro - 5 - [3,6 - dihydro - 3 - methyl - 2 - 1 - 4 - (trifluoromethyl) - 1 - (2H) - 2-chloro-5-methoxy-4-pyrimidinyl] - 4 - Fluoro - N - [[methyl - (1-methylethyl) amino] sulfonyl] benzamida B.A single herbicide B selected from sulfentrazona, flumioxazin, dicamba and its salts and esters and C. at least a herbicide C different from the herbicides A and B is selected from: C.1. Herbicide acetolactate synthase inhibitors of the group C2. Herbicides from the group of protoporfirinogene oxidase inhibitors C.3. The group of synthetic auxin herbicides C.4.The group of inhibitors of microtubule herbicides C.5. Herbicides from the group of inhibitors of acetyl CoA carboxylase C.6. Herbicides of the group of inhibitors of fotossistema II, c.7.Herbicides from the group of inhibitors of the synthesis of pigments and c.8.The group of herbicides inhibitors selected from VLCFA chloroacetamide herbicides, oxiacetamida herbicides.Acetamide herbicides and herbicide of tetrazolinona since the combination herbicide does not include piroxassulfona provided that,If the components (b) or (c) understand dicamba or one of its salts or esters, the combination herbicide does not include imazapir or one of its salts and since,The component (b) is flumioxazin and the component (c) is 2,4 - D, 2,4-D is present as the salt of 2 - ethyl - Hexila.a presente invenção refere-se a uma combinação herbicida que compreende: a. herbicida a que é 2-cloro-5-[3,6-di-hidro-3-metil-2,6-dioxo-4-(trifluorometil)-1-(2h)-pirimidinil]-4-fluoro-n-[[metil-(1-metiletil)amino]sulfonil]benzamida b. um único herbicida b selecionado a partir de sulfentrazona, flumioxazin, dicamba e seus sais e ésteres e c. pelo menos um herbicida c diferente dos herbicidas a e b que é selecionado a partir de: c.1. herbicidas do grupo de inibidores de acetolactato sintase c.2. herbicidas do grupo dos inibidores de protoporfirinogene oxidase
