Effect of biopreparations on dynamics of the number of bacteria and phytopathogenic fungi in potato agroecosystem

Application of biological preparations such as Phytotsid and Planryz favoures the growth of the general number of soil's bacteria population compared with control by 13.0-36.1% in the variant of potato variety Scarbnytsya and by 4.5-24.6% of potato variety Oberig. It also decreases 1.2-1.8 time...

Description
Summary:	Application of biological preparations such as Phytotsid and Planryz favoures the growth of the general number of soil's bacteria population compared with control by 13.0-36.1% in the variant of potato variety Scarbnytsya and by 4.5-24.6% of potato variety Oberig. It also decreases 1.2-1.8 times the number of soil phytopathogens--Fusarium and Alternaria. During the application of Rovral Akvaflo the Shenon's ecological index of species biodiversity was lower than during the bioprepation application. One could observe a decrease of species biodiversity and dominance of dark pigmentation in fungi--Alternaria sp., Cladosporium sp., Phoma sp., Doratomyces sp., and pigmented bacteria.
