Abstract

Aim: The main objective of the study was to evaluate efficacy Calotropis procera, Adansonia digitata, and Manihot esculenta in the remediation of soil-borne fungal diseases of Tomato.

Method and Materials: A biological screening for antifungal activities was conducted on 4 species of pathogenic fungi isolated from diseased tomato. Three plants (Calotropis procera, Adansonia digitata, and Manihot esculenta) were used for the treatment of soil-borne fungal diseases of Tomato.

Results: The Laboratory analysis showed that the plants extracts totally inhibited the growth of the pathogens (100%). In the field, C. procera was effective in inhibiting disease symptoms caused by Aspergillus glaucus, A. fumigatus and A. sclerotirium with a significant increase in some agronomic parameters of the tomato plants compared to the control set up (P<0.05). Other extracts had significant effects in the control of the induced disease too suggesting their usefulness in plant disease management.

Conclusion: The findings from this research concluded that bio-pesticides are as effective as chemicals to safeguard life and the environment, manufacturers of pesticide should be considered natural alternatives.
