Abstract

The bioefficacy of biocontrol agents, Trichoderma harzianum isolates
(Th-M & Th-P) and Trichoderma viride isolate (Tv) was studied against
Fusarium head blight pathogen of wheat (Fusarium graminearum) in vitro
and under green house conditions (pot trial). Dual culture technique
was used for testing the potential of Trichoderma isolates against seven
isolates of F. graminearum in vitro. Trichoderma harzianum (Th-M) was
found most effective in significantly reducing the radial growth of
all F. graminearum isolates followed by T. viride. Foliar application of
T. harzianum (M) and T. viride alone and in combination significantly
reduced the disease severity as compared to control. Maximum
reduction in disease severity was achieved with combined application
of T. harzianum and T. viride.
