Resumo: Abstract Invasive exotic grasses are among the biggest obstacles to the success of reforestation projects. The aim of this study was to evaluate the efficiency of the crowning with cardboard in suppressing the grasses Urochloa humidicola and Megathyrsus maximus aiming its use in reforestation areas. A field experiment was installed in a completely randomized design with two treatments consisted of crowning with cardboard and without crowning (control). The crowning with cardboard caused a progressive reduction of the biomass and was effective in causing senescence of both grasses in 80% or more of the crowning area between 20 and 50 days after the crowning (F test; p<0,05). These results demonstrate the effectiveness and potential of using the crowning with cardboard to control alien grass species in reforestation areas. This method brings as an innovation the possibility of placing cardboard directly on the grass after mowing, allowing greater simplicity and lower operating cost.
