摘要
由多主棒孢(Corynespora cassiicola)引起的橡胶树棒孢霉落叶病是继南美叶疫病之后最具破坏性的橡胶树叶部病害,该病已在云南河口地区发生为害。本文首次报道了云南橡胶树棒孢霉落叶病病情调查结果,并通过病害诊断、病原菌基础生物学特性测定和分子分析,明确该病病原为多主棒孢病菌[Corynespora cassiicola(Berk and curt.)wei]。
The Corynespora Leaf Fall Disease （CLFD） of Hevea brasiliensis, caused by Corynespora cassiicola, has recently made a threat, after the South American Leaf Blight （SALB）, to natural rubber production in the world. The disease has occurred in Hekou rubber plantations. This article first reported the results of disease severity investigation and pathogeny identification on Corynespora Leaf Fall Disease by disease diagnosis, biological characteristics analysis and molecular identification. It was identified that the pathogeny of Corynespora Leaf Fall Disease was Corynespora cassiicola （Berk and curt.）Wei.
