Lumber is the raw material for the wood industry. Much of the bark from these logs is either buried or incinerated without any form of recovery. This study was carried out to verify the antifungal power of the trunk barks of two forest species: Terminalia ivorensis and Terminalia superba, on two fungal parasites, Fusarium oxysporum lycopersici and Sclerotium rolfsii of the tomato. They were tested in vitro using the double dilution method. Ethanol extracts from both species significantly inhibited the radial growth of both mycopathogens (100 ± 00 and 68.46 ± 5.35). T. superba was fungicidal at 25mg/ml against F. oxysporum lycopersici and S. rolfsii. T. ivorensis was fungistatic at 25mg/ml against F. oxysporum lycopersici and fungicidal at the same concentration against S. rolfsii. These barks generally contain a wide variety of raw natural products that can be a potential source of new molecules effective against phytopathogens.
