Abstract:: Taking seedling blight diseased leaves of Lonicera japonic Thunb. collected from Anlong country Southwest Guizhou as material，the isolation was separated and identified using tissue isolation method，and its toxicity determination was determined,in order to understand the occurrence characteristics of seedling blight and put forward control methods.The results showed that the seedling blight pathogen was identified to be Rhizoctonia solani Kuhn..5 fungicides were tested in vitro for efficacy against the Rhizoctonia solani Kuhn.Test on mycelia growth showed that 50% carbendazim，70% mildothane，80% thiram were the most effective fungicides.Based on occurrence characteristics of Lonicera japonic Thunb.Seedling blight，some corresponding control suggestions were put forward，including reasonable rotation，timely sowing，strengthen field management and chemical control and so on.
