Five species of Trichoderma viz., Trichoderma Viride, T. harzianum, T. Koningii, T. aureoviride and T. pseudokoningii were evaluated for their in vitro antagonistic potential against Fusarium oxysporum, the cause of wilt disease in sweet peppers (Capsicum annum). Among the Trichoderma species T. viride showed the best performance in vitro biological control of Fusarium oxysporum followed by T.harzianum,T. aureoviride, T. koningii and T. pseudokoningii, respectively, resulting in 62, 36, 24, 18 and 6% reduction in colony growth of the test pathogenic fungus respectively.
