The control of Purple nutsedge (Cyperus rotundus) and Crabgrass (Digitaria spp) in the cultivation of sugar cane must be made in an integrated way mainly in the reform or implantation of the sugar cane plantation. Amongst the measures that can be adopted for reduction of the potential of infestation of Purple nutsedge and Crabgrass it is the daily application of pre-emergence herbicides in the plantation of sugar cane. It was aimed with this work to study the effectiveness of the herbicides sulfentrazone and clomazone used in sugar cane areas in the control of the Cyperus rotundus L species respectively. For this a survey of the areas with application of these herbicides was carried through and made a visual evaluation of control from the 70 to 90 DAA with regard to the witness of each plantation spot. The data had been tabulated and analyzed with the use of histograms and polygon of frequency. The results allowed concluding that there might be problem areas for the herbicide sulfentrazone in high infestations of the harmful plant Cyperus or when the applied doses are inferior of the recommended for the control of the same one. The control of the herbicide values found over the capim-colchão allows assuming it to be an option for the handling of this harmful plant.Downloads
