The Oil Palm (Elaeis guineensis) is an Important tree crop in the tropics. In South East Asia, oil palm has been cultivated more than 100 years. Like all crops, it is susceptible to pests and diseases, which can cause very serious losses in production. Oryctes rhinoceros, bagworm, Tirathaba sp., and Ganoderma are posing a serious threat to the oil palm if left unmanaged. The problems become complicated with some current issues like resistency of some weeds and less aggresive of Elaeidobius kamerunicus as main polinator in oil palm plantation. The 6th IOPRI-MPOB International Seminar Will present the lastest findings on identification and managemet of pests and diseases on oil palm for high productivity. The seminar will be hold in conjungtion with 100th years IOPRI anniversary in September 2016.
