- A study to control of Basal Stem Rot (Ganoderma boninense Pat.) on the palm oil seedling (Elaeis guineensis Jacq.) using local chitinolitic bacteria has been done in Microbiology Laboratory, Biology Department, Mathematic and Natural Sciences Faculty, North Sumatera University, from February to July 2011. The purpose of the research was to study the ability of local chitinolitic isolated from Bangka, Langkat and Karo LK08, KR05, BK13, BK17, and BK15 to inhibit the growth of G. boninense on the palm oil seedling. Antagonistic test showed that the most effective bacteria in inhibiting the growth of G. boninense was BK17 with inhibiting zone of 12,63 mm, whereas the least effective bacteria was BK15, with inhibition zone of 8,05mm. Disease incidences was higher in control (20%) compared to bacterial treatments. Less disease incidence was found in treatments of BK17 and KR05(4%). Microscopic observation showed that G. boninense hyphae was abnormal i. e. lysis, curved, rolled and dwarf due to the fungus.
