Abstract The rhizomes of Zingiber cassumunar exhibited strong fungitoxic action against Rhizoctonia solani, the damping-off pathogen. On chemical and spectral investigations, the antifungal compound was found to be zerumbone — a sesquiterpene. Its minimum effective dose against R. solani was 1000 ppm, much lower than some commercial fungicides. Zerumbone had fungistatic activity, a narrow fungitoxic spectrum and was not phytotoxic. Moreover, when used as a seed treatment, zerumbone could control damping-off disease of Phaseolus aureus caused by Rhizoctonia solani by 85.7%.
