A serious disease of cardamom in East New Britain Province of Papua New Guinea was shown by pathogenicity and biochemical tests to be caused by Erwinia chrysanthemi. The bacterium was repeatedly isolated from blackened roots, soft discoloured rhizome tissue and rhizosphere soil, but not from field soil in the immediate neighbourhood of diseased plants.
