Abstract
Gray mold and leaf blight of true lavender, Lavandula augustifolia (L.) Mill., and stevia, Stevia rebaudiana Bertoni M., occurred in Tokyo Metropolis in 2005. The fungi isolated from the infected plants with gray mold were identified as Botrytis cinerea Persoon: Fries. Inoculation tests showed that these fungi were causal agents of the diseases. This is the first report of gray mold on these plants in Japan.
