A dual culture method was practiced in order to observe the interaction between Poria and the soil isolates. This method was slightly modified by allocating Poria in the middle and the soil isolate was inoculated 2 cm from the periphery of the plate; opposite to each other. The soil isolates was labeled as Noor Fazila (NF)-1, NF- 2, NF- 3, NF- 4, NF- 5, NF- 6, NF- 7, NF- 8, NF- 9, NF- 10, NF- 11 and NF- 12. After twelve days of interaction, two isolates; NF-1 and NF-5 were identified as potential antagonist organisms and suspected to be Cunninghamella sp. Other successfully isolated fungi are Trichoderma, Stylopage, Verticillium, Blastomyces, Ovulariopsis, Periconia and Ustilago. The rest of the fungi showed either agonism or mutualism interaction against Poria.
