Hot water dips elicit disease resistance against anthracnose caused by Colletotrichum musae in organic bananas (Musa acuminata)

Abstract Anthracnose of banana is an aggressive disease, difficult to control during export. Moreover, in organic banana the incidence of this pathogen is higher than in traditional crops due to the lack of use of synthetic fungicide during the pre-harvest period. The effectiveness of hot water dips has been studied in order to reduce C. musae growth and to determine their effect on postharvest and shelf-life physicochemical and sensory quality, with the goal to incorporate them into integrated pest management, and to reduce the use of chemicals. Hot water treatment at 40 °C for 20 min elicited a C. musae severity inhibition (49.5%) significantly higher ( p p p
