Abstract

The invention discloses a fungicide composition containing pyraclostrobin and ethylicin and application of the composition, and belongs to the field of vegetable disease prevention. The composition comprises pyraclostrobin and ethylicin, and the weight ratio of pyraclostrobin to ethylicin is (1-30):(2-40). The composition can be used for preventing melon, fruit and vegetable diseases caused by ascomycetes, basidiomycetes, oomycetes and fungi imperfecti, and has the advantages that the fungicidal effect is good, plant growth can be regulated, consumption and use frequency of chemical pesticides are reduced, and drug resistance is not likely to be generated.
