We studied the fungicidal activity of a biological preparation from the fungi of the genus Chaetomium against soil phytopathogenic fungi Rhizoctonia solani and Fusarium oxysporum. The inhibitory effect of the preparation under study depended on its concentration, duration of storage, and growth characteristics of pure cultures of the phyropathogens. The highest (98.8%) inhibitory activity was observed on the third day of the interaction with Rhizoctonia solani. After a 2-year storage, this preparation was capable of inhibiting the growth of phytopathogens only at high doses. The preparation precluded the development of a bare patch but increased the productivity of potato plants. The preparation may serve as an alternative to chemical fungicides for plant protection.
