The invention discloses a metrafenone-containing bactericidal composition, which consists of a first active ingredient and a second active ingredient, wherein the first active ingredient is metrafenone; the second active ingredient is strobilurin fungicide which is selected from azoxystrobin, (E)-2-[2-(2, 5-dimethyl phenoxyl toluene)-benzyl]-3-methoxy methyl acrylate and coumoxystrobin; and the weight ratio of the first active ingredient to the second active ingredient is 1:10-20:1, preferably 1:5-10:1. The composition can be prepared into agriculturally permissible formulations such as water dispersible granule, wettable powder, suspension and dispersible oil suspension. The metrafenone-containing bactericidal composition has the advantages of rational composition, good bactericidal effect and low medication cost; the activity and the bactericidal effect of the metrafenone-containing bactericidal composition are not simple superposition of activity of each component; and compared with the conventional single preparation, the metrafenone-containing bactericidal composition has an obvious bactericidal effect and an obvious synergistic effect, is pollution-free for crops, has high safety, meets the safety requirements of agricultural preparations and has an obvious prevention and treatment effect on powdery mildew, downy mildew, epidemic diseases and anthracnose of the crops. |
