  • Abstract : In order to assess different methods of health-purpose defoliation on the severity of black leaf streak disease under conditions of intensive cultivation in Côte d’Ivoire, this study was conducted in the Agro-industrial farms of Banacomoé, located in the Mé region. The treatments consisted in carrying out surgery (removal of portion of leaves at stage 6) and sanitation (removal of 25% of leaves if stages 4-5-6 were noticed on the tip of the leaf, 50 % of leaves if stages 4-5-6 were noticed on half of the leaf, and the entire leaf, if stages 4-5-6 were noticed on more than half of the leaf). Both treatments were carried out on two plots forming a compact block. On the plot where defoliation was done using the sanitation method, the weekly assessments of symptomatological parameters of BLSD (SE, YLS, YLN) made on 10 banana trees during the assessment period (January 2012-July 2012) revealed a very significant reduction in the amount of inoculum. On the other hand, the daily yield was estimated at 3.6 ha for sanitation, while it was 2.2 ha for surgery. There was no significant difference between the numbers of functional leaves at flowering whatever the treatment, while this difference could be noticed at harvest.
