Abstract

Several natural organic products were tested for their capability to support the growth and sporulation
of Trichoderma. These were pagass, rice straw, sawdust, peanut shell and whey. Rice straw gave the
highest sporulation followed by sawdust. On the other hand, whey, which gave no spores when added
to any of the aforementioned materials, increased the growth and sporulation. Spores viability of
Trichoderma was measured at intervals of 10 days for two months. Field experiment revealed different
responses of kidney bean plant to the treatment with these substrates. Trichoderma with rice straw
were the most effective. It significantly reduced Sclerotinia rot disease and supported plant growth
compared to control, and all other used materials. Pagass alone showed a great effect on plant vigor.
