Antimicrobial Effect of the Wood Vinegar from Cryptomeria japonica Sapwood on Plant Pathogenic Microorganisms

Abstract

The antimicrobial effect of the wood vinegar of C. japonica sapwood and its constituents was evaluated against Ralstonia solanacearum, Phytophthora capsici, Fusarium oxvsporum, and Pythium splendens. Phenols and guaiacols had a strong antimicrobial effect against four kinds of microorganisms, but methanol and acetic acid exhibited little or no antimicrobial activity.
