Evaluation of Trichoderma Strains as Biocontrol of Fusarium oxysporum F. sp lycopersici in Tomato
Author(s): Hope Takudzwa Mazungunye* and Elizabeth Ngadze
Tomato (Lycopersicon esculentum) is an important crop which provides people with essential nutrients e.g. potassium and phosphorus as well as anti-oxidants important in fighting cancers. Its production is threatened by the wilts caused by a fungus called Fusarium oxysporum f. sp Lycopersici which can cause yield losses of 50-100%. The disease is mainly controlled by use of synthetic chemicals which can pose a threat to human health and the environment. This study evaluated the use of Trichoderma strains as potential biocontrol of the Fusarium oxysporum f. sp Lycopersici. In-vitro experiment was a dual culture experiment with six treatments arranged in a Completely Randomized Design. The results showed Trichoderma strains (T. harzianum, T. asperellum – CA, C9, NY) reduced mycelial growth of Fus.. View more»
