Abstract

The invention relates to a sterilization composition containing cyazofamid and cyprosulfamide as well as use of the sterilization composition. The weight ratio of cyazofamid and cyprosulfamide contained in the sterilization composition is (45:1) to (1:55). The sterilization composition can be used for controlling diseases of plants such as industrial crops, fruits or vegetables, and is wide in application range, high in effect, low in cost and residue, and safe to people, livestock, the environment and the like.

Description

(1) Technical field [0001] The invention relates to a bactericidal composition and its use, in particular to a bactericidal composition containing cyfafamidazole and boscalid, which is mainly used for the prevention and treatment of diseases of economic crops. (2) Background technology [0002] Cyazofamid (Cyazofamid, CAS No. 120116-88-3) is a sulfamidazole bactericide, a super protective bactericide, with good protective activity and certain systemic therapeutic activity, long lasting period, resistance to rain erosion, Safe and convenient to use. Cyanofamidazole has specific effects on downy mildew, blight, root edema, damping-off and so on. The mechanism of action is to block the electron transfer of the mitochondrial cytochrome bc1 complex in the oomycete bacteria to interfere with the supply of energy. Its binding site is the Q center of the enzyme, which has no cross resistance with other fungicides. Its high selective activity against pathogenic bacteria may be caused by...
