Abstract

Trichoderma “viride” TNAU is the most widely used biofungicide in India with more than 250 registered commercial formulations being available. We have studied the phylogenetic position of this strain using a molecular marker and determined that this commercial strain is, in fact, a strain of Trichoderma asperelloides, and not T. viride. The implications of these findings on the registration and commercial distribution of biofungicides based on this strain has been discussed.

Keywords: Trichoderma viride, T. asperelloides, biofungicides, formulations.
