<br/><br/> Pathogenicity test showed that potato plants were highly susceptible to pathogenic fungi Rhizoctonia solani, Fusarium dimerum, F. oxysporum, Cladosporium herbarum an Nigrospora sphaerica. The maximum number of harvested tubers was found in case of R. solani, while heavier tubers were in case of F. dimerum, F. oxysporum, N. sphaerica and C. herbarum
