Abstract

Introduction. This protocol aims at monitoring the development of Sigatoka disease (Mycosphaerella musicola / Pseudocercospora musae) of banana plants in order to control this disease with a minimum of fungicide applications. A good timing of fungicide application will result in lower cost of control, lower risk of fungicide resistance and lower negative environmental impact. The principle, key advantages, starting plant material and expected results are presented. Materials and methods. Details of the seven steps of the protocol allowing banana plot preparation, data collection, stage of evolution of the disease (SED) calculation, and timing of fungicide applications are described. Possible troubleshooting is mentioned. Results. Weekly observation of selected banana plants allows filling in a data sheet used for the calculation of the SED. A graphic representation of the weekly evolution of this SED can then be used for timing of fungicide spraying decisions.
