Abstract


Distribution of Trichoderma spp. and Penicillium spp. and their antagonism to Phytophthora palmivora.

The distribution of Trichoderma harzianum, T. viridae and Penicillium spp. and their antagonism to Phytophthora palmivora were studied by isolating the fungi and in vitro test of antagonist. Soil samples were collected from Sukamulya (West Java) and Petaling (Bangka) Exp. Garden, farmer’s garden in the distric of Cahayanegeri (North Lampung) and Sukadana (Central lampung). The distribution of the fungi varied from one place to another. The highest population was found at Sukamulya Exp. Garden and the lowest was at the farmer’s garden in Sukadana. The population difference was assumed to correlate with cultural practices, vegetation and the climate. Trichoderma spp. developed lysis on mycelium and zoospore germination P. palmivora. Penicillium spp. caused mal-formation of mycelium, aborted sporangium and inhibited zoospore germination of the fungus.
