The objective of this experiment was to verify the applicability of some homoeopathic solutions in the rust control in the grape culture of the region of Marialva (PR). The used homoeopathic solutions were Silicea 30CH and Isoterapic 6CH, 12CH and 30CH. The homoeopathic drugs were applied for aspersion (manual pulverizer type spray) in the leaves of the grapevines during the beginning of the bud development in the proportion of 2ml of the homoeopathic solution for 0,5 L of water. The experimental delineation was entirely in randomized blocks, with 3 repetitions. The evaluations of the degree of visual severity of the rust attack were made being colected 5 leaves/plant, in the phenological stage number 41 to the 43, in agreement with the scale of Eichhorn and Lorenz. The homoeopathic treatments reduced the rust atack substantialy when compared to the control (water). The homoeopathic solutions Silicea 30CH (S 30CH), Isoterapic 6CH, 12CH and 30CH (ISO 6CH, 12CH and 30CH) they only presented 7, 17, 9 and 18% of the severity degree presented by the treatment controls (100%), respectively. The results suggest that the homoeopathic solutions can be an alternative viable and ecological y correct for the control of biotic factors that commit the productivity in the grape culture.
