Morphological and diagnostic characteristics of the pathogen Sphaerotheca pannosa var.rosae in rose culture

In our country in Kosovo and in Albania, growth surfaces cultivated with this decorative plant is growing every day more and more while farmers are so concerned with the cultivation of large losses grew because of exactly the occurrence of this disease in cultivars market requirements. In our experimental thesis work during 2018 vegetation we have diagnose the presence of pathogenic Sphaerotheca pannosa.We have also identified the time of infection in untreated susceptible cultivars. In samples taken in leafages, we diagnosed the symptoms characteristic macroscopic forms of white mold and leafages such I have sent to identify labortor reproductive organs pathogen-conidia. Making their size measuring microscope (length and width) expressed in microns square.Taking samples from ten leafages and flowers on each plant, twice during the vegetation, has enabled us, to determine the degree of vulnerability in the leafages and flowers.
