广东桉树梢枯病病原鉴定

Identification of Pathogens Caused Eucalyptus spp. Die-Back from Guangdong Province

摘要: 对近年来发生在广东湛江、韶关、惠州等地桉树梢枯进行调查采样和病原菌的分离，致病性测定及种类鉴定的结果表明，七叶树壳梭孢Fusicoccum aesculi Sacc.、围小丛壳Glomerella cingulata (Stonem.) Spauld. & H. Schrenk和可可毛色二孢Lasiodiplodia theobromae (Pat.) Griffon & Maubl.均可导致桉树梢枯发生，其中F. aesculi和G. cingulata复合侵染是桉树梢枯严重发生的主要因素.
