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%.

1. A process of disinfecting citrus fruit, comprising contacting the fruit with a composition effective against a pathovar of Xanthomonas axonopodis pathogenic for citrus, wherein the composition comprises an aqueous solution of a carboxylic acid, hydrogen peroxide, and a percarboxylic acid product
1. A process of disinfecting citrus fruit, comprising contacting the fruit with a composition effective against a pathovar of Xanthomonas axonopodis pathogenic for citrus, wherein the composition comprises an aqueous solution of a carboxylic acid, hydrogen peroxide, and a percarboxylic acid product thereof, and the percarboxylic acid is present at a concentration of less than 200 parts per million. 2. The process of claim 1, wherein said contacting comprises a time sufficient for reducing the pathovar by at least 99.9%. 3. The process of claim 1, wherein said contacting is sufficient to reduce the pathovar by at least 99.9% within approximately one minute. 4. The process of claim 1, wherein the composition further comprises up to approximately 1% by weight sulfuric acid. 5. The process of claim 1, further including drying after contacting. 6. A process of disinfecting citrus fruit, comprising contacting the fruit with a composition effective against a pathovar of Xanthomonas axonopodis pathogenic for citrus, wherein the composition comprises an aqueous solution of acetic acid, hydrogen peroxide, and peroxyacetic acid, and the peroxyacetic acid is present at a concentration of less than 200 parts per million in equilibrium with said hydrogen peroxide and acetic acid. 7. The process of claim 6, wherein said contacting comprises a time sufficient for reducing the pathovar by at least 99.9%. 8. The process of claim 6, wherein contacting is sufficient to reduce the pathovar by at least 99.9% within approximately one minute. 9. The process of claim 6, wherein the composition further comprises up to approximately 1% by weight sulfuric acid. 10. The process of claim 6, further including drying after contacting. 11. A process of disinfecting equipment used with citrus fruit, comprising contacting the equipment with a composition effective against a pathovar of Xanthomonas axonopodis pathogenic for citrus, wherein the composition comprises an aqueous solution of a carboxylic acid, hydrogen peroxide, and a percarboxylic acid product thereof, and the percarboxylic acid is present at a concentration of less than 200 parts per million. 12. The process of claim 11, wherein said contacting comprises a time sufficient for reducing the pathovar by at least 99.9%. 13. The process of claim 11, wherein said contacting is sufficient to reduce the pathovar by at least 99.9% within approximately five minutes. 14. The process of claim 11, wherein the composition further comprises up to approximately 1% by weight sulfuric acid. 15. The process of claim 11, further including drying after contacting. 16. A process of disinfecting equipment used with citrus fruit, comprising contacting the equipment with a composition effective against a pathovar of Xanthomonas axonopodis pathogenic for citrus, wherein the composition comprises an aqueous solution of acetic acid, hydrogen peroxide, and peroxyacetic acid, and the peroxyacetic acid is present at a concentration of less than 200 parts per million in equilibrium with said hydrogen peroxide and acetic acid. 17. The process of claim 16, wherein said contacting comprises a time sufficient for reducing the pathovar by at least 99.9%. 18. The process of claim 16, wherein said contacting is sufficient to reduce the pathovar by at least 99.9% within approximately five minutes. 19. The process of claim 16, wherein the composition further comprises up to approximately 1% by weight sulfuric acid. 20. The process of claim 16, further including drying after contacting.
