Problems solved by technology

[0006] As mentioned above, although there are examples in the prior art about the compounding of the above-mentioned fungicides and some fungicides to achieve synergies, they are basically limited to binary compounding, and there is no compounding of the above-mentioned three fungicides. to report
In addition, the existing pesticide compounding patents mainly only consider the synergistic effect brought about by the compounding. However, although the synergistic effect is the more obvious the better, it is not the only factor to be considered when using pesticides. In particular, it needs to be considered Yes, the toxicity and environmental pollution of the compounded composition
For example, although some active ingredients are not a big problem when they are used separately, after they are used in combination, the intermediate products produced during their degradation process may undergo adverse chemical reactions and cause environmental pollution problems

Embodiment 1

[0028] Example 1 50% trifloxystrobin prothioconazole carbendazim water dispersible granules

[0029] The raw material formula of the water-dispersible granules is shown in Table 1, wherein the disintegrant is carboxymethyl cellulose, the binder is starch, and the filler is diatomaceous earth.

[0030] The preparation method of water-dispersible granules is as follows: pre-mix and re-mix all materials except starch according to the formula, pulverize through a jet mill, then transfer to a kneader, add water and starch to knead, extrude and granulate, and dry.

[0031] The technical indicators of water dispersible granules are as follows: the technical indicators are as follows: suspension rate ≥ 88%; disintegration time ≤ 45s; wetting time ≤ 60s; water content ≤ 2.5%; (through 75μm sieve) ≥97%; persistent foaming (after 1min) ≤20ml; particle size range (0.8mm~1.5mm) ≥97%; suspension rate ≥84% after heat storage at 54±2℃ for 30 days.

Embodiment 2

[0032] Example 2 35% trifloxystrobin prothioconazole carbendazim water dispersible granules

[0033] The raw material formula of the water-dispersible granules is shown in Table 1, wherein the disintegrant is carboxymethyl cellulose, the binder is starch, and the filler is kaolin.

[0034] The preparation method of water-dispersible granules is the same as that of Example 1, and the technical indicators are as follows: suspension rate ≥ 90%; disintegration time ≤ 45s; wetting time ≤ 60s; water content ≤ 2.5%; pH value 6.0-9.0; dispersibility ≥ 88%; Sieve analysis (through 75μm sieve) ≥ 97%; persistent foaming (after 1min) ≤ 20ml; particle size range (0.8mm ~ 1.5mm) ≥ 97%; suspension rate ≥ 85% after heat storage at 54±2℃ for 30 days.

Embodiment 3

[0035] Example 3 50% trifloxystrobin · prothioconazole · carbendazim water dispersible granules

[0036] See Table 1 for the raw material formula of the water-dispersible granules, wherein the disintegrant is alkylphenol polyether, the binder is starch, and the filler is diatomaceous earth.

[0037] The preparation method of water-dispersible granules is the same as that of Example 1, and the technical indicators are as follows: suspension rate ≥ 90%; disintegration time ≤ 45s; wetting time ≤ 60s; water content ≤ 2.5%; pH value 6.0-9.0; dispersibility ≥ 88%; Sieve analysis (through 75μm sieve) ≥ 97%; persistent foaming (after 1min) ≤ 20ml; particle size range (0.8mm ~ 1.5mm) ≥ 97%; suspension rate ≥ 85% after heat storage at 54±2℃ for 30 days.

Abstract

The invention relates to a ternary compound sterilizing composition containing trifloxystrobin and application of the sterilizing composition. The ternary compound sterilizing composition comprises an active component, and auxiliary components of pesticide preparations, wherein the active component is compounded by the trifloxystrobin, prothioconazole and carbendazim according to the weight ratio of (0.1-1): (0.1-1):1. The ternary compound sterilizing composition has the advantages that since the trifloxystrobin, the prothioconazole and the carbendazim are compounded according to the specific proportion, an obvious synergistic interaction effect is obtained; and compared with a sterilizing composition subjected to two-component compounding, the ternary compound sterilizing composition has an expanded bacteriocidal spectrum and has the special effect for diseases such as leaf spot disease, downy mildew, scab and anthracnose of fruit trees, vegetables and cereal crops. In addition, proved by many experiments, the toxicity to mammals is not increased after compounding. An applicant further discovers that the compounding effect of the active component can be further enhanced by means of specific wetting dispersants and dispersing wetting agents, and the synergistic action can be played at the most extent.

Description

Technical field [0001] The invention belongs to the field of pesticides, and particularly relates to a three-component compound bactericidal composition containing trifloxystrobin and its application. Background technique [0002] Prothioconazole, English name: prothioconazole, molecular formula: C 14 H 15 C 12 N 3 OS, chemical name: (RS)-2-[2-(1-chlorocyclopropyl)-3-(2-chlorophenyl)-2-hydroxypropyl]-2,4-dihydro-1,2 , 4-triazole-3-thione, is a new broad-spectrum triazole thione fungicide developed by Bayer. The original drug is white crystal and has the advantages of low toxicity, no teratogenicity, no mutagenicity, no toxicity to embryos, and safety to humans, animals and the environment. The mechanism of action of prothioconazole is to inhibit the demethylation of lanosterol, the precursor of sterols in fungi, at the 14- or 24-position of methylenedihydrolanosterol, that is, demethylation inhibitors (DMIs) . Prothioconazole not only has good systemic activity, but a...
