Field study was conducted during two successive seasons of Williams banana Cv., grown in loam soil under surface flood irrigation system, located at Al-Daqahlia and Domietta Governorates, and in sandy soil at Beheira Governaratein Wadi Alnatroon, under drip irrigation system in Egypt. Our study investigated the relationship between application of alternative fungicides and chemical fungicides alone and combined on the severity of fungal root rot disease and their effects on banana trees growth. Disease reducing was observed by using inducer compounds i.e ascorbic acid, citric acid and salicylic acid and fertilizers i.e., potassium and copper combined with protective fungicide (copper oxychloride).The chemical fungicide of copper oxychloride, followed by the organic acids and nutrients fertilizers reflected the higher reduction in the percentages of frequency occurrences of fungal pathogens it reveals 10%,5%,0% and 0%frequency of Fusarium oxysporum, Macrophomina phaseolina , Verticillum Sp. and Botrydiplodia sp. respectively Though, the alternative fungicides in combined with protective fungicide is safety strategy for control banana root rot disease, which will defense banana trees against fungal root rot disease infection .On the other hand, the economic aspect plays the major role in this respect.
