广东桉树梢枯病病原鉴定

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.cin-gulata复合侵染是桉树梢枯严重发生的主要因素....

After investigating and specimen collecting of Eucalyptus spp.die-back disease in Zhanjiang,Shaoguan and Huizhou in Guangdong province,pathogen isolation,pathogenicity test and pathogen identification were performed.The results showed that Fusicoccum aesculi Sacc.,Glomerella cingulata（Stonem.） Spauld. Schrenk.and Lasiodiplodia theobromae（Pat.） Griffon Maubl.were responsible for the disease,joint infection by F.aesculi and G.cingulata was the main factor of its serious occurrence.
