Efficiency of Cardboard Crowning on the Suppression of Invasive Alien Grasses

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