The oil palm is of high economic value due to its palm oil, palm kernel oil and palm wine liquor. Yield of this crop remains low and among the limiting factors, fungal and bacterial diseases are of utmost importance. This study aimed to identify fungal and bacterial diseases of the oil palm, their incidence and distribution in Ndian Division, Cameroon. In 2018, ten plantations at two locations (Kokundu and Lipenja) in Ndian Division were surveyed for fungal and bacterial diseases infecting the oil palm. 10 symptomatic and 2 asymptomatic samples of plant parts were collected randomly from each plantation, cultured and identified using their standard protocols. Results indicated that 10 fungi and 3 bacteria were isolated from the 120 plant samples. 38.2% of samples had fungi which include Botryodiplodia theobromae (BT), Cercospora sp., Colletotrichum gleosporiodes, Curvularia lunata,, Corynosporium sp. Fusarium oxysporium, Fusarium verticilioides, Ganoderma boninensis, Penicillium sp. Trichoderma sp. and 21.8% bacteria; Bacillus cereus, Bacillus substilis, Xanthosomas sp. Fusarium oxysporium was the most abundant with incidence between 3.3% to 35% while Bacillus cereus was the most abundant bacterium with incidence ranged between 5% to 21.6%. Corynosporiun sp. and Trichoderma sp. were absent in Kokundu while BT and Cercospora sp. were not identified in Lipenja. Mixed infection was noted in 22 samples with 17 having 2 and 5 with 3. Latent infection with BT, Curvularia sp. and Bacillus substilis was noticed in 20% of the asymptomatic samples. This study has established the occurrence of 10 fungi and 3 bacteria infecting oil palm in Ndian Division, Cameroon with Fusarium oxysporium and Bacillus cereus being the most abundant fungus and bacterium respectively.
