花椒枯穗病是2009年河北省林业科学研究院引进花椒新品种上发现的一种新病害,在示范种植期间主要危害花椒穗部和叶部,导致穗部干枯,叶片脱落,有时也侵染果皮,造成花椒产量和品质下降。本实验室将引起该病的病原菌鉴定为细极链格孢菌Alternaria alternata(Fries)Keissler(Yang et al.,2013),并筛选获得了对其具有较强拮抗作用的多粘类芽胞杆菌Paenibacillus polymyxa菌株Z-X-225 Ziziphus jujuba is a new disease found on the introduction of new varieties of Zanthoxylum bungeanum in Hebei Academy of Forestry in 2009, which mainly endangered the spikes and leaves of Zanthoxylum bungeanum during the demonstration planting period, resulting in dry ears, exfoliated leaves and sometimes infected Peel, causing pepper yield and quality decline. In our laboratory, the pathogen causing the disease was identified as Alternaria alternata (Fries) Keissler (Yang et al., 2013), and the Paenibacillus polymyxa strain with strong antagonistic activity was screened out polymyxa strain ZX-225
