Abstract:
Background and Objective: Development of a strategy to control black leaf streak disease results from the analysis of phytosanitary practices adopted in industrial plantations. This study aimed to understand the means of control implemented for managing the disease. Materials and Methods: In 2013, a study on black leaf streak disease management methods was carried out in the Southeastern Côte d’Ivoire. A survey in 17 industrial plantations made it possible to collect phytopathological and productivity data which were analyzed with Statistica 7.1 software. Results: The main results revealed that black leaf streak disease is well known and its presence has been reported in 100 p.c. of the plantations. About 44 p.c. of cases of cohabitation of black and yellow Sigatoka was reported. Integrated pest management combining leaf sanitation by removing the necrotic parts and applying synthetic fungicides is practiced in 100 p.c. of the plantations surveyed. The fungicides of the triazole, strobilurin, morpholine and benzimidazole families are used mixed in 60 p.c. and alternately in 100 p.c. of plantations. The level of disease pressure indicated by the rank of the Youngest Leaf Touched is higher in the Agneby-Tiassa region and is unevenly distributed in the production basin. Conclusion: The control methods for black leaf streak disease are practically identical in all the plantations surveyed except for the frequency of cutting and the stages of the disease eliminated during sanitary leaf stripping. This should be done as frequently as possible during periods of high pest pressure and concerned stages 3 or 4 of the disease.
