This study was conducted with the aim of taking stock of Ganoderma sp disease in oil palm plantations in the Lokondola division of Boteka. This disease causes significant losses and constitutes a major obstacle to the sustainability of replantings. Ganoderma, which is increasingly growing in the DRC, deserves particular attention, in order to develop methods that can limit its spread in the different production areas.
Our analyzes showed different results. From a pathological point of view, all blocks presented at least one diseased foot. The disease was higher in bocs 111a and 112a with average incidences ranging between 10.2 and 8, and a little less in the rest of the blocks with averages of (3.2 to 4.7). The disease situation in different block plots of the division indicates that the disease is important in plots 23 and 18 of block 111a, with 14 and 11 sick subjects respectively. As for block 112a, the disease is higher in plots 14 and 15 (10 and 8 sick subjects) and lower in plots 24a and 25 (6 and 8 sick subjects).
The assessment of the disease levels in the rest of the blocks of the plantation shows a situation comparable to the previous ones with values between 3 to 7 sick subjects.
