The invention discloses a bactericidal composition containing cuppric nonyl phenolsulfonate and triazole fungicide. The bactericidal composition comprises a first active ingredient cuppric nonyl phenolsulfonate and a second active ingredient triazole fungicide selected from hexaconazole, tebuconazole, difenoconazole and epoxiconazole, wherein the weight ratio of the first active ingredient to the second active ingredient is 1:10-15: 1 and preferably is 1:5-10:1. The bactericidal composition can be prepared into missible oil, microemulsion and suspension emulsion which are allowable agriculturally. The bactericidal composition is reasonable in ingredients, good in bactericidal effect and low in pesticide cost, and the activity and the bactericidal effect are not produced by simple superposition of activity of the ingredients. Compared with existing single preparations, except the remarkable bactericidal effect, the bactericidal composition has remarkable synergistic effect, is free of pollution to crops and good in safety, meets the safety requirements for pesticide preparations and has remarkable prevention and control effect on false smut and bacterial stripe of rice. |
