Abstract
sUMMARY: The control of Purple nutsedge (Cyperus rotundus) and Crabgrass (Digitaria spp) in the cultivation of sugar cane must be done in an integrated way, mainly in the reform or implantation of the sugar cane plantation. Among the measures that can be adopted for reduction of the potential of Purple nutsedge and Crabgrass infestation 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 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 it was possible to happen areas the herbicide sulfentrazone in high infestations of the harmful plant Cyperus or when the applied doses are inferior to the recommended for the same one. The control of the herbicide over the capim-colchao allows assuming that it’s an option for the handling of this harmful plant.
