Influence of Biopreparation 'Alirin-B' on Cytomorphometric Characteristics of Conidia of Fungus Fusarium spp. Causing Potato Dry Rot

摘要

Food and agricultural product safety during manufacture and turnover is a keystone in development of food market in many countries. Fusarium dry rot is the most common plant disease. Biological protection of agricultural plants is one of the alternative methods to reduce soil damage against mineral fertilizers. Our work was to study the dynamic influence of biological fungicidal commercial product "Alirin - B" with active substance of Bacillus subtilis B-10 VIZR on digital cytomorphometric characteristics of Fusarium spp. reproduction cells. The fungal mycelium was taken in the 5% glucose solution. Two sample cultivated types were researched: conidia in glucose solution with fungal mycelium (control), conidia in glucose solution with fungal mycelium and "Alirin - B" (experiment). The individual macro- and microconidia digital cell cytomorphometric characteristics of Fusarium spp. (square, length, width, number) were obtained. "Alirin-B" obliterates macro- and microconidia and thus affects the Fusarium spp. reproduction system. The digital microorganism conidia cytomorphometric method could be recommended as a testing system in development of new plant biofungicidal products.
