PATHOCOMPLEX OF PATHOGENIC FUNGUS IN TABLE CARROT AND RHIZOSPHERE DEPENDING ON A GROWING REGION

In the pathocomplex of any agricultural crop, there are different micromycetes, composition which varies depending on weather and climatic conditions, seasonal changes. The fungus A. dauci (J. G. Kühn) Groves et Skolko is one most harmful pathogens table carrots, affecting leaves, petioles, stems. radicina Meier, Drechsler E. D. Eddy damages carrot root crops during storage, causing a hard rot, coal-black, sharply delimited from healthy tissue.
 These occur everywhere simultaneously; n addition, optimal conditions for development both similar. Yield losses Аlternariа can reach 40–99 %. complex fungal species genus Fusarium ubiquitous soil pathogen with wide phylogenetic ontogenetic specialization, causes destructive vascular wilting, necrosis.
 common F. oxysporum avenaceum, latter also exist as saprotroph. As result work done, released mycelium drawing up palette described. It was revealed that colonies fungi light-colored (54.8%) were larger in samples Voronezh region, based Fusarium. Moscow region sufficient moisture, isolates slightly dominated (43.7 %). Rostov frequency occurrence dark-colored average 58.1%, by Alternaria.
