| Abstract: | Pathogen identification, pathogenicity and biological characteristics were carried out on dieback occurring
on young rubber trees of 7-33-97 in Xinzhong Farm, Wanning, Hainan were reported in this study. The results of
morphological characteristics of the pathogen and identification of molecular biology techniques showed that the pathogen was Lasiodiplodia theobromae (Pat.) Criff.et Maub. The results of biological characteristics test showed that 30 ℃, pH 4, glucose as carbon source and soybean peptone as nitrogen source were the optimum conditions for the pathogen growth. Different light conditions had little effect on the growth rate of the pathogen hypha |
