Abstract

L'invention fournit un procédé d'inhibition de maladie de conservation des fruits ne mettant pas en œuvre de pesticide. Plus précisément, l'invention fournit un procédé qui est caractéristique en ce qu'il inclut une étape au cours de laquelle un fruit récolté pédoncule compris, est mis en contact, avec un agent bactéricide contenant un acide peracétique selon une concentration supérieure ou égale à 10ppm et inférieure à 100ppm, avant sa conservation et ou son transport. Selon l'invention, il est possible d'inhiber de manière significative la maladie de conservation des fruits pendant un intervalle de plusieurs jours à plusieurs semaine nécessaire à un acheminement dans une région éloignée du pays ou à l'étranger et/ou pendant la durée du transport.
