RESUMEN
The biocontrol programs that are currently developed focus on specific microorganisms that live in plant tissues, also known as the endophytes. This article discusses pathogenic micromycete species that infected herbaceous plants growing in the Yereymentau District, Akmola Region. Four fungi species were detected that belong to the same genus. Information about the species composition and a brief description of each fungus were provided. The seasonal behavior of rust fungi was investigated. As it turned out, rust fungi tend to go through the uredinium phase in July and to produce teliospores in September. The research population includes the most common species of rust fungi. This article was first to identify phytopathogenic fungi that attack herbaceous plants in the Yereymentau District and their seasonal behavior. The findings may contribute towards expanding the global fungal database with information about fungal diseases specific to the given region and towards combat against a variety of phytopathogenic fungi.
RESUMEN
Purpose: Vegetation plays a very important role in industrial regions in terms of not only air purification, but also oxygen enrichment, air humidity, and city aesthetics. The paper presents the authors' study of oleaster mildew during 2012-2013 in the cities of Pavlodar, Ekibastuz, and Aksu. Method: The species composition of mildew, patterns of its growth and reproduction, seasonal dynamics, and the level of trees infection according to a six-score scale were determined. Result: Three cultivars of mildew from three genera were registered. The species composition of mildew of oleaster is studied for the first time in large industrial cities of the Pavlodar region. The comparative analysis of the systematic structure of phytopathogenic fungi was followed by the study of the micro flora of green planting in megalopolises. The seasonal dynamics of growth, development, and reproduction was determined. The impact of pests on host-plants was studied. Conclusion: Timely diagnosis and localization of disease outbreak increases the likelihood of successful treatment and saving of plants.
