Black Sigatoka remains to be the most costly disease of banana accounting to about 35% of the production cost. Management of the disease entails application of registered fungicides following an efficient and effective spray program in order to manage the risk of resistance. A wide selection of fungicides is very ideal, however, through the years, only few products are being positioned for Black Sigatoka management thus increasing the chance of Pseudocersopora fijiensis to develop resistance. In these situations, inclusion of resistance-breakers in the spray program becomes imperative in banana plantations. 1,8- cineole is known to degrade cell walls of fungi causing their lysis and death. With the aim to add novel products in the spray program, efficacy of 1,8-cineole against P. fijiensis was determined in vitro following the method set by Fungicide Resistance Action Committee (FRAC
