First Report of Damping-off of Celery Caused by Rhizoctonia solani in Japan

Abstract

Damping-off of celery (Apium graveolens L.) occurred in Hachijo Island of Tokyo Metropolis in 1999. A Rhizoctonia species isolated from the diseased plants was identified as Rhizoctonia solani Kühn. Inoculation tests showed that the fungus was the causal agent of the disease. This is the first report of the disease in Japan.
