Portugués. The corn (Zea Mays L.) resistant to nonselective herbicides, found in soybean crops, originating from seed germination lost in mechanical harvesting is considered an invasive plant. Resulting from this, the study was to evaluate ACCase inhibitors and ALS herbicides with and without glyphosate, noting their effectiveness for controlling voluntary plant corn resistant to glyphosate herbicide. The work was conducted in UNIVAR experimental field located in the county of Barra do Garças - MT. The experimental design was randomized blocks, factorial 6x2, totaling 12 treatments and 4 repetitions. The first factor was composed of the treatments: control, Haloxyfop-P-methyl, Tepraloxydim, Sethoxydim, Fenoxaprop-p-ethyl, and Imazethapyr. The second factor consists of the same treatments with the addition of glyphosate. The evaluations within 15 days after the application was only significant difference between treatments and evaluations to 45 DAA was interaction among the factors, with satisfactory results. The Haloxyfop, Fenoxaprop and Tepraloxydim herbicides were efficient in controlling corn plants resistant to glyphosate herbicide applications in the stadium v8. They did not show satisfactory control herbicides, Imazethapyr and Sethoxydim, and the latter showed interaction among the factors to 30 DAA.
