In Vitro evaluation of some fungicidal bioactive chemicals against fusarium spore germination and survival

The genus Fusarium are the most important pathogens associated with different plants including crop plants, fruits, vegetables, etc. causing of constrained production and productivity crops. Bioactive compounds are environmentally friendly and amenable. This study aimed to evaluate the effectiveness of some bio-active compounds derived from Bacillus strain for the in vitro control of Fusarium mold. Seven (7) isolates of the Fusarium complex were isolated from various stored fruits, vegetables and food grains using Potato Dextrose Agar (PDA) media supplemented with antibacterial agent. The growth and survival of the respective spores were challenged with supernatants of overnight-grown culture of Bacillus subtilis TC17 for 20 minutes. The supernatant prevented the germination of spores of some fungi strains in the order; F. solani, F. oxysporum, F. equiseti, F. acuminatum, F. proliferatum, F. moniliforme and F. tricinctum against control. Therefore, this research showed that the bio-active agent can be used to control the pervasive plant pathogenic fungal species with outstanding result and therefore should be developed further for registration for commercial applications.
