The objective of this work was to evaluate a pasture of Slack Oats (Avena strigosa) + autuai ryegrass (Loliuni inaltiflonetn)introduced by sodseeding in a nativo pasture with and without herbicide application. and to observe the effect of the herbicides on piam succession. The herbicides used were glyphosate (540. 1080, and 1620 g/ha a.i.) diuron + paraquat ( 300 g/ha a.i. + 600 g/ha a.i.) and paraquat ( 600 g/ha a.i.). The dry matter production (DM) was higher in the treatments with herbicides. and mean crude protein content and in vinn organic matter digestibility (I VOM I)) were similar. The treatments did not affect the occun .ence of Desmodiant incantun. The higher doses of glyphosate increased the participation of Ventania nueliflorn, Eryngiunt horrithun, uncovered.soi I and inter, and reduced Paspaltini notatunt. The herbicides diuron + paraquat, and paraquat increased the presence of Paspalunt notaram, decreased uncovered soi I and litter. and maintained Etyngium horridutn. Paraguai decreased the occurrence of Ventania nurliflora.
