Abstract

In glasshouse experiments, different concentrations of Trichoderma harzianum (Th. Azad)  was evaluated for biological control of fungal wilt of tomato caused by fusarium. The aim of this research article was to evaluate the bioefficacy of the Trichoderma (Th.azad) species to promote the growth and yield parameters of tomato genotype (Azad T-6) and to manage Fusarium wilt disease under in vitro conditions. Trichoderma was proved as an effective and potential biocontrol agent against Fusarium infecting tomato. During an in vitro biocontrol test, Trichoderma showed mycoparasitism and destructive control against the tested fungal pathogen. The virulent Pathogen Fusarium significantly influences the germination of tomato. The root system of the tomato plant was poorly developed due to the infection. During pot assay along with biocontrol activity, Trichoderma showed growth promoting action on the tomato plant. Trichoderma enhanced growth of shoot and root systems and fruit yield after 4 month of growth. Trichoderma harzianum (Th. Azad) showed the least disease incidence (by 15.45%) compared to control (by 25.50%). Tomato plants treated with Trichoderma harzianum (Th. Azad) also showed a significant stimulatory effect on plant height, Root length, shoot length , fruits and  the dry weight of tomato plants in comparison to other concentrations of Trichoderma and untreated control.
