Distribution of representatives "malicious synergies" polyphages of the genus Fusarium spp. schlecht and aspergillus sp. nees in corn crops in Kuban

Over the past two decades toxinogenic fungi of the genus Fusarium Link develop rapidly and in a peculiar way. In the agricultural enterprises of the Agrarian and Industrial Complex of Kuban the problems of mushroom phytotoxicity soils with prevalence of this fungus has been identified. Nurseries have appeared which are marked up to 80% of the death of seedlings from Fusarium root rot of Apple trees, fields of winter grain crops with low annual harvests - 17-26 C/ha. Low yields are observed and with other crops, even against the background of mineral fertilizers application. A new term has appeared - "problem fields". In degraded soils there is a destruction of microbial systems, changes in the structure of microorganisms with a predominance of pathogens. In such soils fungi appear of the genus Fusarium, causing Fusarium disease 32 of crops of Kuban. On the background of intensive development of Fusarium suddenly there appeared joint damage caused by the other soil - inhabiting fungus Aspergillus excl.planed Nees. This issue requires examination of the joint, a binary distribution, development and harmfulness of fungi of the genus Fusarium Link with a certain kind of saprotroph on major crops. The development of biological methods of soil micocoenosis improvement is as well important to increase suppressive mikati, recovery and optimization of physico-chemical properties of Kuban soils phytotoxicity.
