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.
Author Keywords: oil palm, Ganoderma, disease, replanting, yield.

Abstract: (french)
Cette étude a été conduite dans le but de faire un état de lieux de la maladie de Ganoderma sp dans les plantations des palmiers à huile de la division de Lokondola à Boteka. Cette maladie provoque des pertes importantes et constitue un frein majeur à la durabilité des replantations. Le Ganoderma qui prend des plus en plus de l’ampleur en RDC, mérite une attention particulière, afin de développer des méthodes qui puisse limiter sa propagation dans les différentes zones de production. Nos analyses ont montré des résultats différents. Du point de vue pathologique, tous les blocs ont présenté au moins un pied malade. La maladie était plus élevée dans les bocs 111a et 112a avec des incidences moyennes oscillants entre 10,2 et 8, et un peu moins dans le reste des blocs avec des moyennes de (3,2 à 4,7). La situation de la maladie dans différentes parcelles de blocs de la division, indique que la maladie est importante dans les parcelles 23 et 18 du bloc 111a, avec respectivement 14 et 11 sujets malades. Pour ce qui est du bloc 112a, la maladie est plus élevée dans les parcelles 14 et 15 (10 et 8 sujets malades) et plus faible dans les parcelles 24a et 25 (6 et 8 sujets malades). L’appréciation des niveaux de la maladie dans le reste des blocs de la plantation montre une situation comparable aux précédents avec des valeurs comprises entre 3 à 7 sujets malades.
