The invention discloses a bactericidal composition containing cupric nonyl 
phenolsulfonate and a methoxy-
acrylate bactericide. The methoxy-
acrylate bactericide is selected from 
azoxystrobin, kresoxim-methyl, metominostrobin, fluoxastrobin, trifloxystrobin, 
orysastrobin, picoxystrobin, pyraclostrobin, enostrobilurin, SYP-1620, phenylatestrobin, 
coumoxystrobin, 
pyraoxystrobin and pyraclostrobin, wherein the weight ratio of the cupric nonyl 
phenolsulfonate to the methoxy-
acrylate bactericide is 1:5-20:1. The bactericidal composition can be prepared into missible oil, 
microemulsion, water-dispersible granules, 
wettable powder and a suspending agent which are permitted in the 
agriculture. The bactericidal composition containing the cupric nonyl 
phenolsulfonate and the methoxy-acrylate bactericide is reasonable in ingredients, good in 
bactericidal effect and low in 
drug cost, and the activity and the 
bactericidal effect are not formed by the activities of the ingredient simply. Compared with an existing single preparation, the bactericidal composition has remarkable synergistic effect except the remarkable 
bactericidal effect, is free of 
pollution to crops and good in safety, meets the safety requirements of 
pesticide preparations, and has remarkable preventive and 
control effect on 
powdery mildew, 
downy mildew, anthracnose and banded sclerotial 
blight of the crops.
