[Abstract] Objective： To study the occurrence of Cercospora leaf spot of Lonicera macrathoides and fungicides control method， so as to provide scientific basis for its integrated pests management (IPM). Method： The field investigation and the field controlling trial were carried out for the research. Result： Cercospora leaf spot was caused by C. rhamni. There was obvious relationship between the damage rate and the altitude， soil organic matter， available K， available P as well as variety. The controlling effect of 10% difenoconazole WG was the highest. 50% Thiram WP， 70% Mancozeb WP also had well controlling effect. Conclusion： Cercospora leaf spot of L. macrathoides could be controlled by suitability agricultural and chemical controls .
