Cassava Root Rot in Côte d'Ivoire: Farmer Perceptions, Indigenous Control Methods, and Production Typologies

Abstract

This study aims to understand cassava producers' perceptions of the disease and to identify the endogenous control methods used by producers. Cassava is a crop of great socio-economic importance in Côte d'Ivoire. However, this crop faces major constraints, particularly tuber rot. The search for sustainable control methods requires an in-depth understanding of the factors responsible and producers' perceptions of this problem. The study is based on a survey conducted in 13 cassava-growing localities, including Aboisso, Abengourou, Adzopé, Agboville, Bouaké, Dabou, Toumodi, Yamoussoukro, Daloa, San Pédro, Man, Katiola and Ferkessédougoud in the main cassava-growing areas throughout Côte d'Ivoire. The questionnaire developed took into account the typology of producers. Questionnaires were submitted to 285 cassava growers. Cultivation practices were assessed during the survey by field observation in 320 plots with a view to describing the cultivation practices employed, their level of knowledge of the disease and endogenous control methods. The results showed that cassava is grown throughout Côte d'Ivoire, with a high proportion of women among producers. This crop is a very important source of income. From an organisational point of view, most producers are not grouped into cooperatives, have a very low level of education and do not receive any support. In terms of farming practices, the results showed that the cuttings used are mostly of variable quality and are not disinfected. Rot is widespread in the plots and the symptoms of the disease are well known to growers. There are no effective control methods. Supervising producers would be an effective and sustainable way of combating tuber rot and would help guarantee cassava production.
