ABSTRACT
<p><b>OBJECTIVE</b>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).</p><p><b>METHOD</b>The field investigation and the field controlling trial were carried out for the research.</p><p><b>RESULT</b>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.</p><p><b>CONCLUSION</b>Cercospora leaf spot of L. macrathoides could be controlled by suitability agricultural and chemical controls.</p>
