In 2008-2009 an experiment was carried out in a 4-year old sour cherry orchard in the region of the town of Hisar. At the end of the vegetation in 2008 the experimental trees infected with cherry leaf spot Blumeriella jaapii were treated with urea - carbamide: Variant 1 – concentration of 2.5%; Variant 2 – concentration of 5%. The leaves of the experimental trees overwintered under natural conditions and the observations on the development of the sexual form of the fungus Blumeriella jaapii started in the spring. The best limiting effect on the pathogen was achieved by treatment with 5% urea.
