Sterilization composition containing active components Bellkute and imazalil

The invention provides a sterilization composition containing active components Bellkute and imazalil and relates to the sterilization composition with a synergistic effect. The sterilization composition is applied to the chemical protection field of agricultural plants and the composition has extremely strong antibacterial and sterilizing activities to harmful funguses in agriculture or gardening. The sterilization composition with the synergistic effect contains the active components Bellkute and imazalil. The weight ratio of the active components Bellkute to the imazalil is between (1:20)-(20:1). The weight percentage of the active components Bellkute and imazalil in the sterilization composition is 10-50%. The active components Bellkute and imazalil, a known adjuvant and an excipient are complexed to form any one preparation acceptable by pesticides; and the selected preparation can be wettable powder, aqueous dispersion granule or a suspension agent. The sterilization composition containing the active components Bellkute and imazalil can be applied to preventing and treating germs harms of grains, fruits, vegetables and cash crops.
