| Abstract: | 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. |
