Endophytic Fungi Isolation on Balinese Grape Plants (Vitis vinifera L. var.Alphonso Lavalle ) and its Effectivenese to Control Grey Mold Disease on Balinese Grape Gray mold rot is the disease caused by pathogen Botrytis cinerea. It is animportant disease in grapes (Vitis vinifera L.) since it can reduce the quantity andquality of grapes. Nowadays people use synthetic fungicides to control the pathogen,but the cost of synthetic fungicides is expensive and continuous usage will give anegative impact to the environment therefore endophytic fungus is an alternative waythat can be used to control the pathogen in grapes. The purpose of this study was toobtain endophytic fungi and obtain the best endophytic fungus to control gray moldrot pathogens. This study uses two methods which are in vitro endophytic fungalantagonist test and in vivo endophytic fungal antagonist test in the laboratory. Theresults showed that there were 10 endophytic fungi. The results of in vitro and in vivotests showed that the best endophytic fungus was Miselia sterilia A as confirmed bythe percentage of inhibition of Miselia sterilia A in the in vitro test of 82.14% and thesmallest percentage of pathogen attack in the in vivo test of 6%.
