title: Effect of crude mansonia (Mansonia altisima) timber extracts on biodeterioration of obeche (Triplochiton scleroxylon) timber by three wood-rotting fungi.
abstract: Methanol and ethanol extracts of mansonia wood inhibited the growth of three wood-rotting fungi, Pleurotus ostreatus, Gloeophyllum sepiarium and Gloeophyllum sp. An aqueous extract only inhibited the growth of P. ostreatus. Extracted obeche wood impregnated with ethanol extracts of mansonia showed significant improvement in decay resistance. Impregnation with methanol extracts only significantly retarded decay by P. ostreatus and the aqueous extracts did not increase obeche wood resistance to any of the test fungi.
