Abstract: Among the various pathogenic fungi Fusarium sp. are saprophytes in the soil and organic matter with a cosmopolitan distribution. While some strains have been known to cause vascular wilt disease in crops including vegetables, bananas and date palms some other strains also protect plants from wilt. Among the genus Fusarium, F. oxysporum has been known to affect tomato plants significantly decreasing its production as they damage roots during their growth stages. Today, the focus on the treatment of plant decreases is mainly oriented towards the use of extracts of natural products as alternatives to synthetic fungicides for their safety and negligible environment impact. The present study involves the use of cyanobacterial extract in the control of F. oxysporum infecting tomato plants.
