Bactericide containing botanical active ingredients

The invention belongs to the technical field of pesticides, and particularly relates to a bactericide containing plant source active ingredients. The invention relates to a bactericide containing plant source active ingredients. The active ingredients of the bactericide are formed by compounding ligustilide and fluopyram or difenoconazole according to the mass ratio of (1-80): (80-1). When the plant active ingredient ligustilide and the chemical active ingredient fluopyram or difenoconazole are compounded, the cotoxicity coefficient is larger than 120, a synergistic effect is shown, the control effect on fungal diseases of crops can be improved, and the usage amount of pesticides can be reduced; meanwhile, generation and development of drug resistance of pathogenic bacteria of fungal diseases of crops can be delayed, and then the risk of drug resistance can be reduced. 本发明属于农药技术领域，具体涉及一种含植物源活性成分的杀菌剂。一种含植物源活性成分的杀菌剂，其活性成分由藁本内酯与氟吡菌酰胺或苯醚甲环唑以1-80：80-1的质量比复配而成。本发明将植物活性成分藁本内酯与化学活性成分氟吡菌酰胺或苯醚甲环唑复配时，共毒系数大于120，表现为增效作用，可
