Problems solved by technology

[0005] Insecticide varieties containing a single active component often have defects of varying degrees in the control of agricultural insecticides, such as narrow insecticidal range, poor control effect, large application dose, easy to produce drug resistance, frequent application, and aggravated environmental pollution. Pollution, etc.
For the prevention and control of resistant pests in agriculture, one way is to introduce new ingredients that have no cross-resistance with existing varieties, but the development cost of new active ingredients is high, the development cycle is long, and the pests will never keep up The speed of resistance generation; other methods, such as crop layout adjustment, rotation of different pesticides, etc., are difficult to really have obvious effects in the actual operation process
[0006] Seed coating is one of the important contents of the country's implementation of the improved seed project. The country proposes that the seed coating rate should increase at a rate of 20% every year. At present, the promotion area only accounts for 23.5% of the planting area, which is in the initial stage, and there are still 76.5% of the planting area. Area to be promoted

Embodiment 1

[0059] Preparation of pyraclostrobin·thiamethoxam·fipronil suspension with a mass fraction of 25%

[0060] pyraclostrobin 5%, thiamethoxam 10%, fipronil 10%; emulsifiers are styrylphenol polyoxyethylene ether phosphate and nonylphenol polyoxyethylene ether, the dosage is 3% and 1% respectively The antifreeze agent is selected from ethylene glycol, and the consumption is 4%; the viscosity regulator is selected from xanthan gum, and the consumption is 0.2%; the water is selected from tap water, and the balance is used.

[0061] The processing process is as follows: add the above-mentioned pyraclostrobin, thiamethoxam, fipronil and other materials into the mixing tank, stir well, and then carry out wet grinding by three series-connected horizontal sand mills, and the ground materials Then stir and mix to obtain the product.

Embodiment 2

[0063] Preparation of 30% mass fraction of pyraclostrobin·thiamethoxam·fipronil suspension seed coating

[0064] Pyraclostrobin 5%, thiamethoxam 20%, fipronil 5%; emulsifiers are nonylphenol polyoxyethylene ether phosphate and polycarboxylate, the dosage is 2% and 2% respectively; antifreeze Select propylene glycol, consumption is 4%; Viscosity regulator selects bentonite for use, consumption 1%; Film forming agent selects carboxymethyl starch sodium, consumption 0.5%; Warning color selects rhodamine for use, consumption 0.3%; Water selects tap water for use, surplus.

[0065] The processing process is as follows: add the above-mentioned pyraclostrobin, thiamethoxam, fipronil and other materials into the mixing tank, stir well, and then carry out wet grinding by three series-connected horizontal sand mills, and the ground materials Then stir and mix to obtain the product.

Embodiment 3

[0067] Preparation of pyraclostrobin·thiamethoxam·fipronil suspoemulsion with mass fraction of 30%

[0068] Pyraclostrobin 2%, thiamethoxam 20%, fipronil 8%; Solvent selects xylene, consumption is respectively 5%; Emulsifier selects fatty alcohol polyoxyethylene ether and polycarboxylate for use, consumption is respectively 4 % and 2%; the stabilizer is selected from epoxidized soybean oil, and the amount is 5%; the antifreeze agent is selected from glycerol, and the amount is 4%; the viscosity regulator is selected from xanthan gum, and the amount is 0.1%; .

[0069] The processing process is as follows: dissolving pyraclostrobin and fatty alcohol polyoxyethylene ether in xylene to obtain a solution; adding thiamethoxam, fipronil and other above-mentioned materials into the mixing tank, stirring well to form a slurry, Then it is wet pulverized by three horizontal sand mills connected in series, and pumped into a shear kettle; the above solution is added to the ground slurry,...

Abstract

The invention relates to a complex insecticidal and bactericidal composition and an application thereof, belonging to the field of pesticides. The active ingredients of the composition comprise pyraclostrobin, thiamethoxam and fipronil. The invention also provides an application of the composition. The complex insecticidal and bactericidal composition disclosed by the invention has the beneficial effects that the complex insecticidal and bactericidal composition can kill the insects and bacteria, is used for seed treatment and is safe to crops, underground drug delivery is realized, the residual quantity of the pesticide on the crops is reduced, and the environmental pollution is alleviated.

Description

technical field [0001] The invention relates to a compound insecticidal and bactericidal composition, which belongs to the field of pesticides. Background technique [0002] Pyraclostrobin, also known as pyraclostrobin, chemical name: methyl (N)-[[[1-(4-chlorophenyl)pyrazol-3yl)-oxygen]-O-methoxy] -N-methoxycarbamate is a newly developed methoxyacrylate fungicide in recent years. Its mechanism of action is a mitochondrial respiration inhibitor, which causes mitochondria to fail to produce and provide the energy required for normal cell metabolism. cell death. Pyraclostrobin has a wide bactericidal spectrum and can control most diseases such as Ascomycetes, Basidiomycetes, Deuteromycetes, Oomycetes, etc.; it has a strong inhibitory effect on spore germination and the growth of mycelium in leaves. It has protective and therapeutic activity, permeability and local systemic activity, long-lasting effect and resistance to rain erosion; it is widely used to control wheat, rice, ...
