Sterilization composition containing 2-cyan-3-amino-3-phenylacrylate and amide bactericides

The invention discloses a sterilization composition containing 2-cyan-3-amino-3-phenylacrylate and amide bactericides; the effective active components thereof are 2-cyan-3-amino-3-phenylacrylate and silthiopham; the weight ratio of the 2-cyan-3-amino-3-phenylacrylate to the silthiopham is (1:20)-(20:1), preferably (1:10)-(10:1). The composition can be prepared to agriculturally allowable water dispersible granule, wettable powder, a suspending agent, suspended seed coating, seed treatment dispersible powder or seed treatment dispersible granule. The sterilization composition has reasonable compositions, good sterilization effect and low pharmacy cost; the activity and sterilization effect thereof are not simple superposition of the activity of all components; compared with the existing single preparation, besides a significant sterilization effect, the sterilization composition has significant synergism, no plant pollution and good safety, meets the safety requirement of pesticide preparations, and has a significant prevention effect on the wheat take-all and a rust disease.
