Determination of the pathogenicity of the fungi

Powdery mildew-causing fungi constitute around ten percent of the documented fungal species found in Uzbekistan. Among these fungi, a significant portion has developed adaptations to thrive in arid climatic conditions, reflecting their ability to endure dry environments. However, it’s noteworthy that there also exists a substantial presence of fungi within this group that prefer moisture-rich surroundings. This variation in ecological preferences is evident not only between different fungal species but also within species belonging to the same botanical family. Such diversity in moisture requirements underscores the complex interplay between these fungi and the unique environmental conditions present in Uzbekistan. The article outlines a methodology and presents experimental data aimed at assessing the pathogenicity of two fungi, namely Leveillula saxifragacearum and Sphaerotheca mors uvae. These fungi are responsible for causing powdery mildew, a fungal disease, in the blackcurrant plant. The significance of this plant lies in its medicinal properties. The study provides insights into the mechanisms through which these fungi affect the blackcurrant plant and cause powdery mildew, which can have detrimental effects on its growth and health. By detailing the experimental approach and sharing gathered data, the article contributes to a better understanding of the interactions between these fungi and the medicinal blackcurrant plant. This research has the potential to guide efforts to manage and mitigate the impact of powdery mildew on blackcurrant cultivation, ultimately preserving and enhancing the plant’s medicinal qualities
