Red grape rotten in storage is a major problem for consumers, moreover the fruit after offering in Pura (Bali island) cannot be stored for long. Efforts to control environmentally friendly diseases are hopeful in the future, using exophytic and endophytic fungi derived from healthy red grapes that need to be utilized. The results showed that red grape rot was caused by Aspergillus niger. Fungi/actinomycetes found in exophytes were 19 isolates while those of endophytes consisted of 5 isolates. Microbes found that have the highest inhibitory power by the fungus Neurospora sp. by 88.89%, and followed by Streptomyces antagonensis and A. flavus respectively at 83.33%. Colonies and the highest prevalence were found in A. flavus at 282.72 cfu/ml of water. Diversity index and index dominance of fungal/actinomycetes of 2.088 and 0.8209 means that the index of diversity is moderate and the index of dominance is high close to one reached by A. flavus. The results of the best antagonist inhibitory test (Neurospora sp.) in vivo showed that the concentration of suspension solution of 250 ml antagonist water spores (10-7/ml water) was the best compared to other treatments
