Abstract

In April of 2003, the gray mold disease occurred severely on statice (Limonium shinuatum Mill. cv. Sophia) grown in the commerical farms in Seosang-myon, Hamyang-gun, Gyeongnam Province, Korea, 2003. The infected plants were started with water-soaking lesions in the stems, the leaves and the flowers became withered and discolored to gray or dark from the tip then gradually expanded to die. The conidia and mycelia of the pathogen appeared on flowers, leaves, calyx and flower stalk. The conidia were gray, 1-celled, mostly ellipsoid or ovoid in shape and were 8~20 × 6~14 μm in size. Conidiophores were 14~34 μm in size. The sclerotia were formed abundantly on potato-dextrose agar. The optimum temperature for sclerotial formation was 20℃. Pathogenicity of the causal organism was proved according to Koch`s postulate. The causal organism was identified as Botrytis cinerea Persoon: Fries based on mycological characteristics. This is the first report on gray mold of statice (Limonium shinuatum) caused by Botrytis cinerea in Korea.

Key Words: Botrytis cinerea, Statice (Limonium shinuatum)
