Problems solved by technology

[0020] At present, the above products on the market mainly exist in a single dose, and long-term single dose use has poor control effects on some resistant bacteria such as rice bacterial streak, bacterial blight, rice blast, etc., and cannot effectively prevent the emergence of resistant bacteria. occurrence and development
The main reason is that it is easy to make the bacteria resistant, followed by the high cost
Long-term use of a single agent has a single point of action, which is the main reason for resistance

Embodiment 1

[0051] Example 2: Process the solid original drug streptomycin sulfate and pyraclostrobin to more than 325-800 mesh by means of jet crushing, then accurately weigh 25% streptomycin sulfate, 10% pyraclostrobin, and disperse 6% alkylnaphthalene formaldehyde condensate sulfonate as an agent, 4% alkylnaphthalene sulfonate as a wetting agent, 4% sodium sorbate as a stabilizer, 0.8% xanthan gum as a tackifier, and simethicone as an antifoaming agent Add 1% foaming agent and deionized water to 100% for initial mixing, shearing, stirring, and dispersing. After preparing a slurry, grind it for 1-2 hours in a horizontal sand mill to make the particle size below 5 microns, and A flowable 35% streptomycin sulfate pyraclostrobin liquid suspension preparation with a certain viscosity.

Embodiment 2

[0052] : Process the solid original drug streptomycin sulfate and kresoxim-methyl to above 325-800 mesh by means of jet crushing, then accurately weigh 22% thiazolyl copper, 10% kresoxim-methyl, dispersant polycarboxylate 6 %, wetting agent alkylphenol polyoxyethylene ether phosphate 5%, stabilizer epoxy soybean oil 5%, defoamer polyether modified silicone defoamer 1%, filler diatomaceous earth to 100% Mix and stir evenly without gravity to make 32% streptomycin sulfate kysstrobin wettable powder.

[0053] Embodiment 4:: use the method of airflow pulverization, process solid original drug streptomycin sulfate and enoxastrobin to more than 800-1000 mesh, then accurately weigh 15% streptomycin sulfate, 15% enoxastrobin, Dispersant Sodium Methylene Dimethyl Naphthalene Sulfonate 8%, Wetting Agent Sodium Dodecylbenzene Sulfonate 5%, Stabilizer Sodium Benzoate 5%, Disintegrant Bentonite 5%, Viscosifier Carboxymethyl Fiber Add 3% of cellulose, 1% of defoamer tributyl phosphate, fil...

Embodiment 4

[0054] Example 5: Process the solid original drug streptomycin sulfate and fenoxystrobin to more than 325-800 mesh by means of airflow pulverization, then accurately weigh 20% streptomycin sulfate, 5% phenoxystrobin, and disperse 6% alkylnaphthalene formaldehyde condensate sulfonate as an agent, 4% alkylnaphthalene sulfonate as a wetting agent, 4% sodium sorbate as a stabilizer, 0.8% xanthan gum as a tackifier, and simethicone as an antifoaming agent Add 1% foaming agent and deionized water to 100% for initial mixing, shearing, stirring, and dispersing. After preparing a slurry, grind it for 1-2 hours in a horizontal sand mill to make the particle size below 5 microns, and It is a flowable 25% streptomycin sulfate · fenoxystrobin liquid suspension preparation with a certain viscosity.

Abstract

The invention relates to the technology of pesticide blending, in particular to a preparation compounded from an antibiotic bactericide particularly referring to streptomycin sulphate and one of the following methoxy-acrylate bactericides: kresoxim-methyl, azoxystrobin, enestroburin, SYP-1620, metominostrobin, Pyraclostrobine, Phenothrin and the like, and the application thereof. In the bactericide, the streptomycin sulphate and the active ingredient B are compounded to expand a bactericidal spectrum and achieve synergy, thereby obtaining undesirable bactericidal effect. The bactericide is used in the mode of a composite, thereby not only improving prevention efficiency, but also lowering use cost and improving the utilization ratio of effective ingredients.
