An exact field experiment was conducted to determine the effect of chemical dressing of tubers with Dithane M 45 75 WG, Prestige 290 FS and Vitavax 2000 FS, and biological dressing with Polyversum on the occurrence and intensity of rhizoctoniosis and anthracnose on the tubers of three potato cultivars (early cultivar Vineta, late cultivars Irga and Wawrzyn). The composition of communities of fungi colonizing potato tubers was also determined. The chemical and biological dressing of tubers significantly decreased the infection by rhizoctoniosis on tubers (except for Prestige in 2004) and the percentage of tubers with microsclerotia. Dithane M 45 75 WG and Vitavax 2000 FS were the most effective in protecting potato tubers against the tested pathogens. The infection rate of tubers of cv. Wawrzyn by Rhizoctonia solani and cv. Vineta by Colletotrichum coccodes was significantly higher, as compared with the other cultivars. The highest decrease in the population size of the causal agents of rhizoctoniosis and anthracnose was stated on tubers treated with Dithane M 45 75 WG and Vitavax 2000 FS. R. solani was completely eliminated in the objects with biological dressing treatment.
