CONTROLE QUÍMICO E CULTURAL DAS PLANTAS DANINHAS NA VIDEIRA 'NIAGARA ROSADA'

This study aimed at controlling the weeds in grapevine `Niagara Rosada' using grass mulching and evaluating the selectivity of three herbicides. The experiment consisted of a randomized complete block design with four replications and the following doses of herbicides: 3.04, 4.05 and 5.06 kg/ha of dichlobenil; 2.00 kg/ha of diuron and 2.40 kg/ha of simazine. There were no differences in grape yield and soluble solids contents of grape juice for the three herbicides or among the doses of dichlobenil used. The herbicides were efficient in controlling Digitaria horizontalis Willd., Amaranthus hibridus L., Sida spp. and Bidens pilosa L. The grass mulching Melinis minutiflora L. was also efficient in controlling the weeds.
