Abstract
Tomato (Solanum lycopersicum L.) is a widely grown vegetable crop acquiring the status
of world’s most popular vegetable due to its importance for nutritive value, processing and export
potential. Tomato is affected by many diseases among which wilt caused by Fusarium oxysporum
f.sp. lycopersici is one of the important disease, resulting in 25-55% yield loss around the world.
Fusarium oxysporum f.sp. lycopersici is a serious soil-borne pathogen and persists for longer
periods in the soil.
The antagonistic activity of Trichoderma against Fusarium oxysporum were examined on
potato dextrose agar plates by dual culture method. The results revealed that, all the antagonists
showed inhibitory effect on growth of the test fungus and were effective in controlling the growth
of pathogen. There were two species of Trichoderma, Trichoderma harzianum (TH) and
Trichoderma viridae (TV). Among the strains of Trichoderma harzianum and Trichoderma viridae
Trichoderma viridae was found to be most effective in inhibiting the growth of Fusarium
oxysporum f.sp. lycopersici of about 40-60% growth of test fungus on 3rd and 7th day respectively,
whereas Trichoderma harzianum inhibited 14.5-20% on 3rd and 7th day respectively.
