Despite the attractive possibility for
controlling seed-borne and soil-borne fungi by using
biological antagonists, very few works have been
conducted and no any work has been done in
Thailand regarding biological control of seed-borne
M. phaseolina in mungbean. Therefore, the efficacy
and environmental concerns, as well as pathogen
resistance to some pesticides, encouraged us to do
research into biological control as an alternative
approach or supplement to pesticides for protection
against M. phaseolina in mungbean. The objective
to conduct this investigation was to find out the
efficacy of bio-control agents viz. Trichoderma
harzianum, Trichoderma harnatum, Trichoderma
viride after seed dressing of mungbean seed with
the conidial suspension in order to control seed-bome
M. phaseolina.
