Abstrak

The main causal factor of the failure of the oyster mushroom (Pleurotus ostreatus (Jacq. Ex Fr.) Kummer) cultivation is baglog-borne fungal contamination which inhibit growth and production of oyster mushroom. Therefore this study was conducted to determine fungal contaminant in the baglog media and its inhibiting ability against oyster mushroom. The research was carried out by observation methods of sample randomly for 10-20% of the total contaminated baglog with three time replication. The results showed that air-borne fungus were potentially cause failure of oyster mushroom cultivation with the highest prevalence was Fusarium spp. (25.6%), while the highest inhibition ability was Mucor spp. (94.7±8.5%). The most dominant of baglog-borne fungal with its prevalence was Trichoderma spp. (35.71%). This fungus was very dangerous for the continuity of oyster mushroom cultivation in Bali. Key words: oyster mushroom, inhibiting ability, fungal contaminants
