Jin Hyeuk Kwon, Chang Seuk Park
Abstract
In May of 2002, the gray mold disease occurred severely on broad bean (Vicia faba) grown in farmer`s fields located in Changseon-myon, Namhae-gun, Gyeongnam provice, Korea. The infected leaves, at first, discolored to gray or dark from the tip, and eventually died. Conidia of the fungus in mass were hyaline or gray, 1- celled, mostly ellipsoid or ovoid and sized 6~22×4~16 mm. Thick conidiophores were formed on PDA with 15~37 mm in width. The sclerotia were readily formed potato-dextrose agar and 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 based on its mycological characteristics. This is the first report on gray mold of broad bean (Vicia faba) caused by Botrytis cinerea in Korea.
Key Words: Broad bean (Vicia faba), Botrytis cinerea, gray mold
