[0022] Physical Test Example 1: The Toxicity Test of Cyazofamid and Fluoramide Compound to Cucumber Downy Mildew

[0023] 1. Test object: cucumber downy mildew [Latin scientific name: Pseudoperonospora cubensis (Berk.et Curt.) Rostov.]

[0024] 2. Test method: refer to "Pesticide Bioassay Test Guidelines NY / T 1156.3-2006", and use the drug-containing medium method.

[0025] 3. Statistical analysis of data: use SAS6.12 statistical software for analysis. Calculate the mycelia growth inhibition rate (%) according to the test data, and obtain the virulence regression equation, correlation coefficient (r), EC 50 and co-toxicity coefficient.

[0026] 4. Evaluation method: Refer to "Pesticide Bioassay Test Guidelines NY / T 1156.3-2006", according to Sun & Johnson (1960) co-toxicity coefficient method (CTC) to evaluate the synergistic effect of drug mixture, that is, CTC ≤ 80 is an antagonistic effect, 80<CTC<120 is an additive effect, and CTC≥120 is a synergistic effect.

Abstract

The invention relates to a sterilization composite containing cyazofamid and flutolanil and application of the sterilization composite. The sterilization composite comprises cyazofamid and flutolanil, wherein the weight ratio of cyazofamid to flutolanil is (50:1)-(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 present invention relates to a bactericidal composition and its use, in particular to a bactericidal composition containing cyafamid and fluoramide, 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 respiratory 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 drugs (QO inhibitors in cytochrome bcl). It has effects on all growth stages of oomycetes, and is active against metalaxyl-resistant or sensitive bacteria. [0003] Flutolanil (Flutolanil, CAS No. 66332-96-5) is an anilide fung...
