Characterisation of Orchards and Diseases of Sugar Cane (Saccharum Officinaruml.) in Côte D'ivoire: Case of Sugar Complexes of Borotoukoro and Zuenoula

Abstract— As part of a study to develop a bacterial biocontrol agent against phytopathogens of sugarcane (Saccharum officinarum L.) in Côte d'Ivoire, an orchard diagnosis was carried out by conducting a survey in two sugar complexes, Zuenoula and Borotoukoro. The aim of this work was to collect socio-demographic data on sugarcane growers and to identify the pathologies encountered in these orchards. A sample of 220 growers was surveyed, with 110 growers per sugar complex. The results of this study showed that the majority of growers are Ivorian (95.5-100 %), with a high percentage of men (80-90.9 %) and more than half are illiterate (46.4-53.6 %). The frequency of phytosanitary treatments is limited to an average of two applications of chemical pesticides per year. None of the growers use biocontrol agents to treat their plantations. Symptoms of fungal diseases (smut, red snot and Pokka boeng) and viral diseases (mosaic dash) are present in the sugarcane plantations surveyed.
