[Objective] The aim was to screen fungicide and biocontrol agents to control jasmine Sclerotium rolfsii Blight. [Method] Nine fungicides and six biocontrol agents were used to test the inhibitory of the growth of Sclerotium rolfsii by using the growth rate and the inhibition zone method. Meanwhile, the control effect to the disease by using chemical and biocontrol agents was also tested in the greenhouse. [Result] Tebuconazole 25% WP and Bacillus strain Bv22 had strong inhibitory to the growth of S. rolfsii. Their LC_(50) values were 2 690.96 cfu/ml and 200.05 μg/L, respectively. Furthermore, Tebuconazole 25% WP didn' t inhibit the growth of Bacillus strain Bv22. In greenhouse test, the control effects of Tebuconazole 25% WP 100 μg/L, Bacillus strain Bv22 10~8 cfu/ml, Tebuconazole 25% WP 200 mg/L mixed with Bacillus strain Bv22 10~7 cfu/ml and Tebuconazole 25% WP 400 mg/L mixed with Bacillus strain Bv22 10~6 cfu/ml to Mixture of Tebuconazole 25% WP and Bacillus strain Bv22 could control jasmine Sclerotium rolfsii Blight effectively.
