The objectives of this experiment were to find out the optimum dosage of fungicide treatment and storability on cacao seed. Split plot design was used in this experiment; main plot were storage periods i.e. I, 3, 5, 7, and 9 weeks and .sub plots were dosages of fungicide (active ingredient carbendazim + mankozeb) 0, 2, 4, 6, g/kg of ,seed with 3 replication. Each unit consisted of 40 seeds. Result (the experiment indicated that control seed (without fungicide) were infected by fungi 90.67 % on the first week and its germination capacity was only 57.33 %. Fungi infection increased rapidly after 1 week and its caused the viability lost. Application of 2, 4, 6 g fungicide/kg of seeds inhibited fungi growth and that treatments maintained seed viabilility until 9 weeks of storage periods. There are no significant difference among fungicide dosage, except on index vigor; application of 4 and 6 g (of fungicide result lower index vigor. Better fungicide dosage was4 .21g/kg of seeds based on quadratic regression Y = 20.80 + 43.10 X - 5.12 X2 (Y = germination capacity, X = dosage fungicide). Dominant fungi infected on seed storage were identified as Fusarium sp and Aspergillus sp. The storability of cacao seed with fungicide treatments on 9 weeks of storage period were still relatively high, the germination capacity more than 80% and the seeding vigor were not different among of all storage periods", }
