Problems solved by technology

[0004] Although Cyazofamida has the above advantages, due to the high cost, there is almost no application in China at present
Although tetrafluconazole has high drug efficacy and wide control spectrum, and is currently widely used, from the perspective of pesticide application, long-term single use of a certain pesticide will easily lead to reduced control efficacy, increased dosage, and drug resistance. , shortened validity period and other issues, the residual risk increases, which is not conducive to the harmonious development of the environment
At present, there is no relevant report on the compounding of cyazofimazole and tetraflumezole at home and abroad

Abstract

The invention relates to a sterilization composite containing cyazofamid and tetraconazole and application of the sterilization composite. The sterilization composite comprises cyazofamid and tetraconazole, wherein the weight ratio of cyazofamid to tetraconazole is (40:1)-(1:45). 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 use, in particular to a bactericidal composition containing cyfafamidazole and tetrafluraneconazole, 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 low-toxic bactericide, with good protective activity and certain systemic therapeutic activity, long lasting period, rain erosion resistance, safe and convenient to use . This drug is a mitochondrial respiratory inhibitor, and its bactericidal mechanism is by inhibiting the Qi in the cytochrome bcl during the metabolism of the bacteria, leading to the death of the bacteria, which is different from the methoxyacrylate drugs. It has an effect on all growth stages of oomycetes, and is active against metalaxyl-resistant or sensitive bacteria. Although cyfafamidazole has the above advantages, it is hardly applied in China due to it...
