IMPACT OF PROPOLIS ON THE OCCURRENCE AND DEVELOPMENT OF PHYTOPATHOGENIC FUNGI

In every country around the world, phytopathogenic fungi cause enormus economic damage. With the growth of the human population, the agricultural production has significantly increased in monoculture, which caused enlarged development of phytopathogenic fungi on crops, orchard et cetera. Over time phytopathogenic fungi developed resistance on standard agricultural agents. Because of this, it is necessary to find new ways in battle against these kinds of fungi.The experimental part of this paper covers usage of propolis solutions in battle against of the occurrence and development of phytopathogenic fungi Plasmoparaviticola and Taphrinadeformans in in vivo conditions on the grapevine (lat. Vitisvinifera) and peach (lat. Prunuspersica). The aim of the study is to determine, with all necessary measurements like pruning, fertilizing, irrigation, time of application of the solution and weather forecast,possibility ofusage propolis in influence on the occurrence and development of phytopathogenic fungi.In recent years, great efforts have been made to introduce natural disease control agents, such as propolis extract in alcohol and aqueous solution to reduce certain growth of phytopathogenic fungi in organic agriculture which can increase sustainable agricultural production.
