The fungistatic activity of chemical substances obtained from the wood of trees has been known for sometime. Recently it was demonstrated that an extractive of the heartwood of the catalpa tree is inhibitive to the growth of Schizophyllum communs Fries, a wood-destroying fungus. The results of experiments reported here are concerned with the inhibitory or fungistatic activity of an extractive from catalpa (Catalpa speciosa Warder) heartwood on the growth of many different types of fungi.
