摘　　要：对桉树焦枯病病原菌３种典型的５隔膜、３隔膜和１隔膜分生孢子进行了研究。５隔膜病原菌致病力最强，３隔膜次之，１隔膜较弱。３种病原菌生长适宜的温度较一致，不同的培养基以及不同ｐＨ值对它们的生长影响较大。杀菌剂菌毒清对３种病原菌有明显的抑制作用。Parch blight was a important disease of eucalypts in South China. A survey was made of 3 typical conidia of pathogen: 1 septum, 3 and 5 septa to determine their pathogenicity. The result indicated, in order of pathogenicity, 5 septa>3 septa>1 septum. Favourable temperature was the same for all 3 conidia. Different media and pH value were significant effect on their growing. Germicide had significant effect on the control of eucalypt parch blight.
