Peculiarities of pathogenic complex formation in sugar beet rhizosphere

The role of sugar beet complex diseases caused by a complex of pathogens has grown in importance. Pathogenic complex of beet root rots of mycosis-bacterial etiologies provoking economic damage in the southern part of the Central Black-Earth Region is of the greatest harmfulness. Change of dominants in the pathogenic complex of rots has been determined that is the result of global climate warming, variety changing, short crop rotations and change of soil mycocenosis strategies.
