Problems solved by technology

As for whether the combination of the other three active ingredients has a synergistic effect and what ratio can be used to obtain a satisfactory synergistic effect, it is impossible to predict
In addition, the patent teaches the use of three active ingredients for compound use, which brings a lot of inestimable troubles to practical operations and applications, such as how to combine the three components with different properties and play the desired effect. effects; for example, the impact and effect on the environment after the three active ingredients are compounded is more difficult to predict and judge
These factors will cause these three or more compound pharmaceutical compositions to be difficult to carry out in practical application and realize industrialization at last

Embodiment 1

[0034] Example 1 30% Trifloxystrobin Prothioconazole Suspension Concentrate

[0035] The raw material formula of the suspending agent is shown in Table 1, wherein: the number average molecular weight of PEO-PPO-PEO is about 2500, containing PEO30wt%; the thickener is gum arabic; the antifreeze is glycerin; the preservative is sodium benzoate.

[0036] The preparation method of the suspending agent is as follows: add each raw material into the sand mill cylinder according to the formula, and after stirring evenly, pre-disperse it with a high shear machine, then transfer it to a sand mill for sand milling, add sanding medium zirconia beads, and start sanding Grinding, so that the average particle size of the material is below 3 μm, stop sanding after 5 hours, filter, remove the zirconia beads, and obtain.

[0037] The technical indicators of the obtained suspension concentrate are as follows: Suspension rate ≥ 95.0%; pH value 6.0-8.0; sieve analysis (passing through a 75μm sieve...

Abstract

The invention relates to a bactericidal composition containing prothioconazole and trifloxystrobin, and the bactericidal composition consists of active components and pesticide preparations as auxiliary components; and especially, the active components consist of prothioconazole and trifloxystrobin in a weight proportion of (0.2-20):1. In the invention, the prothioconazole and the trifloxystrobin are compounded in a special proportion, so that a very significant synergistic interaction effect is obtained. A mass of experiments show that the toxicity to mammals is not increased after the prothioconazole and the trifloxystrobin are compounded. Furthermore, the applicant further discovers that the bactericidal composition containing prothioconazole and trifloxystrobin can be used for further promoting the compounding effect of the prothioconazole and the trifloxystrobin with the adoption of a special wetting dispersant and a dispersion wetting agent, so that both the prothioconazole and the trifloxystrobin play a synergistic role to a maximum extent.

Description

Technical field [0001] The invention belongs to the field of pesticides, and particularly relates to a bactericidal composition containing prothioconazole and trifloxystrobin. 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 also has excellent protect...
