A method of preventing and/or treating plant disease resulting from growth of Ralstonia Solanacearum by foliar application to plants of a composition containing 3-IBA. While this 3-IBA composition may contain a racemic mixture of (S) and (R), in the most preferred treatment, the composition contains (S) isomers of 3-IBA. Most preferably, at least two foliar applications are undertaken, spaced apart by more than one day.
