Abstract

Introduction. This protocol aims at detecting and quantifying quiescent infections of Colletotrichum musae on bananas. The principle, key advantages, starting plant material, time required and expected results are presented. Materials and methods. The materials required and details of the three steps of the protocol (fruit sampling, fruit ripening and anthracnose lesion quantification) are described. Possible troubleshooting is discussed. Results. The protocol results in the quantification of anthracnose lesions on the fruits, which makes it possible to predict postharvest losses due to anthracnose (peel rot), and also to propose a better management of postharvest fungicide applications.
