Cocoa pod disease (BBK) caused by the fungus Phytophthora palmivora is one of the prime diseases that can affect cocoa production systems in the world . This disease can cause yield losses of up to 90% , especially in the rainy season and the dry season. Objective of the research is to determine the ability of inhibitory fungus A. Niger in various carriesr and storage time against Phytophtora palmivora cause rotten disease of cocoa. Result of the research is to control the disease in cacao plants. This is an experimental research designed by using Random Complete Design with 2 factorials, carries and storage period with 3 remedials, factor 1: (P0 = control), (P1 = white glutinous rice flour + cassava starch), (P2 = Cassava starch), (P3 = white glutinous rice flour + sweet corn flour), (P4 = white glutinous rice flour), (P5 = ripe coconut flour). Factor 2: (A1 = 1 week storage period), (A2 = 2 weeks storage period), (A3 = 3 weeks storage period), (A4 = 4 weeks storage period). Result of the research proved that the carrier of white glutinous rice flour + sweet corn flour (P3) and ripe coconut flour (P5) and in A3 storage period (week-3) is more effective to inhibiting P. palmivora growth, therefore can be used as a carrier to support A. Niger fungus growth.
