Abstract

The invention relates to a sterilization composite containing cyazofamid and fludioxonil and application of the sterilization composite. The sterilization composite comprises cyazofamid and fludioxonil, wherein the weight ratio of cyazofamid to fludioxonil is (45:1)-(1:50). The sterilization composite can be used for preventing and controlling diseases on commercial crops, cereal or flowers and plants, is wide in application range, excellent in effect, low in cost and residue, and safe to human, livestock, environment and the like.

Description

(1) Technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition containing cyafamid and fludioxonil, which is mainly used for the prevention and treatment of economic crop diseases. (2) Background technology [0002] Cyazofamid (Cyazofamid, CAS No. 120116-88-3) is a new type of low-toxic fungicide, which has good protective activity and certain systemic therapeutic activity, long-lasting effect, rain-resistant, safe and convenient to use . The drug is a mitochondrial respiration inhibitor, and its bactericidal mechanism is to inhibit the Qi in cytochrome bcl in the process of bacterial metabolism, resulting in the death of bacteria, which is different from methoxyacrylate agents. It has effects on all growth stages of oomycetes, and is active against metalaxyl-resistant or sensitive bacteria. [0003] Flutolanil (Flutolanil, CAS No. 131341-86-1) inhibits the transfer related to glucose phosphor...
