Efficiency of certain fungi in biocontrol of fusarium wilt of tomato [electronic resource].

Includes reference.

Ability of certain fungi include Penicillium oxalieum, PenicilJium purpurogenum and Cunninghemella echinulta to reduce severity of Fusariwn wilt in tomato have been studied under both laboratory and greenhouse conditions. In vitro, these fungi exhibited high ability to inhibit the growth of Fusarium oxysporum f. sp. Lycopersici (FOL), C. echinulata was the most efficient one in inhibiting growth of FOL by mycelial growth, while P. purpurogenum was the most potent one to inhibit FOL growth by culture filtrate. Under greenhouse conditions these tested fungi were applied through three different methods as seed, seedling and soil treatment. Previous treatments showed high capability to reduce severity of Fusarium wilt in tomato either in from of vascular browning or foliar yellowing, but efficiency of control was affected by both kind of tested fungus and application method. Generally seedling treatment with P. oxalicum yielded to the best control.
