A disinfectant composition is disclosed effective against a pathovar of Xanthomonas axonopodis pathogenic for citrus, comprising an aqueous solution of a carboxylic acid, hydrogen peroxide, and a percarboxylic acid product thereof. In a preferred composition the percarboxylic acid comprises peroxyacetic acid in an equilibrium aqueous solution with hydrogen peroxide, and acetic acid. The composition is used in a process to disinfect citrus fruit and equipment used therewith by contacting with a sufficient concentration of the composition for a sufficient time for reducing the organisms by at least 99.9%.
