Bactericidal composition containing prochloraz and lentinan and application thereof

The invention belongs to the field of pesticides, and discloses a bactericidal composition containing prochloraz and lentinan and application thereof. The bactericidal composition uses prochloraz and lentinan as main effective components, wherein the weight ratio of the prochloraz to the lentinan is (1-70):(1-50). The bactericidal composition can be used for preventing and treating diseases on cereals, melons and fruits, or vegetable crops, has higher synergic effect, overcomes and postpones the drug resistance of pathogenic bacteria, has the advantages of high bactericidal speed and long duration time, lowers the use cost, and has obviously better preventing and treating effects than a single agent.
