The article presents research work on the biological and ecological features fungi which affecting seed crops. Were collected seeds of cereals five district like Aksu, Kerbulak, Panfilov, Karatal and Eskeldy in Almaty region. Grain seeds include Triticum aestivum L., Avena sativa L., Hordeum vulgare L.,Oryza Sativa L., Zea Mays L. and Panicum miliaceum L. The collected seeds are sterilized and melted in warm foam. Within a few days, the formation of anthrax in seed seeds was completed. Depending on the morphological features of histopathology, varieties of Litvinov (1967) were identified. Were discovered these types of fungi: Alternaria alternata (Fr.)Keissl., Mucor mucedo Fresen., Cladosporium herbarum (Pers.) Link, Penicillium expansum Thom, Macrosporium commune Rabenh. and so on. Subsequently, the study of these types of phosphorus was further investigated, and a clean niche was planted separately for the mushroom Petri dish. The purpose of the study is to discover the biological characteristics of fungi species damaging grains, to identify the factors that impede their development and to find ways to combat them. Key words: Alternaria alternata (Fr.)Keissl., Mucor mucedo Fresen., Cladosporium herbarum (Pers.) Link, Penicillium expansum Thom, Macrosporium commune Rabenh., fungi, grains, seed crops
