Efficacy of Cultural filtrate of Trichoderma Isolates on the Fusarium Wilt of Bael

Percent reduction of F. solani colony over the control 7 days after treatment were 74.88, 69.68 and 72.42 in T. harzianum, T. viride and T. virens treated soil, respectively. But a reverse picture was noticed after 21 days of the treatment. When per cent reduction in population of F. solani in T. harzianum, T. viride and T. virens treated soil were 72.59, 77.62 and 74.57 in a separate experiment. Efficacy of 7 days old culture filtrates of the Trichoderma species in reducing population of F. solani in soil was also tested. Per cent reduction of F. solani 3 days after the treatment with culture filtrates of T. harzianum, T. viride and T. virens were 42.70, 53.57 and 31.40, respectively.
