Abstract


It is well known that Trichoderma spp. can be used as a biological control agent against variety of plant pathogens. In this study, Trichoderma species were isolated from rhizosphere samples of various sites in Zhejiang province, China. A total of 41 soil samples were processed for the isolation of single cell culture of Trichoderma sp. Out of which, 32 species of the genus Trichoderma, were isolated and characterized by using single spore isolation method. The isolates were subjected to sequencing, for precise identification up to species level. Trichoderma harzianum was isolated from maximum (09) number of soil samples, followed by T. velutinum, isolated from 3 soil samples. The other isolated species of the genus Trichoderma were; lixii, atroviride, koningii, longibrachatum, rossicum, gamsii, koningiopsis, tomentosum, afroharzianum, viride, citroviride, aureoviride, simmonsii and hamatum. It was concluded that Trichoderma sp. were abundantly found in the agricultural soils of Zhejiang province, China.
