Manipur is one of the North eastern states of India,
comprising valley and hill districts with a sub-tropical
monsoon climate. The geo-climatic condition of the region is
responsible for creating specific niches for diverse life forms.
Although extensive investigations have been carried out on
species diversity of higher plants and animals, the region
represents a virgin ground for exploration as far as microbial
biodiversity is concerned. Therefore, the present investigation
has been carried out to determine the species diversity of
Trichoderma occurring in the soils of Manipur and to observe
the antagonistic activities of the most promising isolates of Trichoderma species against soil-borne pathogen F.
oxysporum f. sp. lycopersici.
