IN VITRO EVALUATION OF MICROBIAL ANTAGONISTS AGAINST SCLEROTIUM ROLFSII FOUZIA YAQUB AND SALEEM SHAHZAD
Abstract: Trichoderma harzianum and T. longibrachiatum were found
to inhibit the in vitro growth of S. rolfsii and produced
coiling around mycelium of S. rolfsii resulting in lysis of hyphae.
T. pseudokoningii, T. polysporum and Gliocladium virens
also inhibited the growth of S. rolfsii. Where Aspergillus
niger, A. fumigatus, A. flavus, A. terreus, A. nidulans, A. sulphureus,
A. parasiticus, A. tamarii, A. versicolar, A. versiclar and A.
wentii were used, colonies of Aspergillus spp., and S.
rolfsii met each other but S. rolfsii later overgrew the
colonies of Aspergillus spp. Pest & Disease Research Lab., Department of Botany, University of Karachi, Karachi-75270, Pakistan. |
