The commercial fungicide benlate, at high concentrations
had average growth inhibition of C. paradoxa when
compared with the growth inhibitions by T. polysporum
and T. viride. Benlate, T. hamatum and T. aureoviride
were also found to be stimulating the growth of the
pathogen at low concentrations of 50, 30 and 10%.
However, these growth stimulations were less when
compared with the control treatments. Minimum inhibitory
concentration (MIC) of T. viride against C. paradoxa was
higher than the other Trichoderma species. Considering
the inhibition of C. paradoxa by T. polysporum at high
concentrations, it was concluded that the antagonist
exhibited better control of the pathogen.
