为给新型生物农药的研发提出依据，用黄连、黄芩、大蒜、金银花、柴胡和连翘6种植物的浸提液单剂及其复合剂对尖孢镰刀菌进行处理，探索浸提液单剂及复合剂对尖孢镰刀菌的影响。综合对尖孢镰刀菌菌落生长和产孢量两方面的影响，植物浸提液单剂的抑菌效果相对较好的处理分别是50%黄连、30%黄芩、20%金银花、60%柴胡、50%连翘、60%连翘以及10%大蒜、30%大蒜、60%大蒜。6种植物浸提液对尖孢镰刀菌均有抑菌作用，以黄连的抑菌效果最好，平均抑菌率为52.95%，平均抑产孢率为59.46%。

The single agent and compound agent of six plant extracts of Coptis chinensis, Scutellaria baicalensis, Allium sativum, Lonicera japonica, Bupleurum chinense and Forsythia suspensa were used to treat Fusarium oxysporum, and the effects of single agent and compound agent of extract liquid on F. oxysporum were explored. The results showed that the fungal inhibition rates of 50% Coptis chinensis, 30% Scutellaria baicalensis, 20% Lonicera japonica, 60% Bupleurum chinense, 50% Forsythia suspensa, 60% Forsythia suspensa, 10% Allium sativum, 30% Allium sativum and 60% Allium sativum were ideal. Among them, the average antibacterial rate of Coptis chinensis was 52.95%, the average sporulation inhibition rate was 59.46%.
