主　　题：Extract of marigold Tomato Fusarium Wilt Inhibitory effect 

摘      要：[ Objective ] The study aimed to explore a new way for the control of Tomato Fusarium Wilt. [ Method ] Different solvents were used to prepare the ex-tracts of marigold, and the inhibitory effects of different extraction solvents and different extraction parts of marigold against Tomato Fusar/um Wilt were compared. [ Result ] Among different solvent extracts of marigold, chloroform extracts had the strongest inhibitory effects against the growth of the pathogen; among the chloro- form extracts from different parts of marigold, root extract had the most obvious inhibitory effect against the disease, followed by flower and leaf extracts, and the in- hibitory effect of stem extract was the weakest. [ Conclusion ] The active components of marigold have inhibitory effect against Tomato Fusarium Wilt, and the plant has good development prospects and application value.
