Abstract:
An experiment was conducted at Sher-e-Bangla Agricultural University (SAU)
during the period from September 2014 to December 2014 for Formulation and
evaluation of Trichoderma based bio-pesticide for controlling foot and root rot of
betel vine. The effect of nine Trichoderma based substrates viz., T

( Trichoderma + Peat soil + Saw dust + Water), T
(Control) were evaluated for growth and sporulation of Trichoderma harzianum and
acting against Sclerotium rolfsii for the management of foot and root rot of betel vine.
The effect of the treatments varied significantly in terms of production of Trichoderma
spore and reducing foot and root rot diseases in comparison to control. Among the
treatments, soil application with T
