Abstract
The aim of studies, carried out in 2001–2002, was determination of usefulness of the biopreparation Polyversum in protection of potato haulm against Phytophthora infestans (Mont.) de Bary. Before planting, tubers of six potato varieties were dressed with the biopreparation. The observations have been carried out since the time of first late blight symptoms. The experiments showed a possibility of Polyversum application in protection of potato plants against Phytophthora infestans.
