Embodiment 1

[0027] Embodiment 1: 22% pyraclostrobin·prothioconazole suspension containing stabilizer and nanocarrier

[0028] Pyraclostrobin 10g, prothioconazole 10g, alkylphenol polyoxyethylene ether formaldehyde condensate sulfate 2g, polycarboxylate 8g, trisiloxane surfactant 1g, propylene glycol 3g, xanthan gum 0.2g, 0.1g of silicone compound, 1g of potassium sorbate, 2g of non-ionic hydroxyl polyethylene oxide block copolymer, 2g of β-cyclodextrin, and the balance of deionized water. The raw materials of the above components are mixed together, sanded and filtered by a sand mill to prepare a 22% pyraclostrobin prothioconazole suspension.

Embodiment 2-6

[0029] Example 2-6: Pyraclostrobin Prothioconazole Suspension Containing Stabilizer and Nano-carrier

[0030] According to Table 1 ( figure 1 ), the compounding ratio of component (A) and component (B), the auxiliary components are: alkylphenol polyoxyethylene ether formaldehyde condensate sulfate 2g, polycarboxylate 8g, trisiloxane surfactant Agent 1g, propylene glycol 3g, xanthan gum 0.2g, silicone compound 0.1g, potassium sorbate 1g, non-ionic hydroxyl polyethylene oxide block copolymer 2g, β-cyclodextrin 2g, deionized water quantity. The specific preparation steps are the same as in Example 1, and finally Preparation Examples 2-7 are prepared.

Embodiment 7

[0031] Example 7: 22% pyraclostrobin · prothioconazole suspension containing stabilizer

[0032] Pyroxystrobin 10g, prothioconazole 10g, alkylphenol polyoxyethylene ether formaldehyde condensate sulfate 2g, polycarboxylate 8g, trisiloxane surfactant 1g, nonionic hydroxyl polyepoxide 2 g of ethane block copolymer, 3 g of propylene glycol, 0.2 g of xanthan gum, 0.1 g of silicone compounds, 1 g of potassium sorbate, and the rest of deionized water.

Abstract

The invention discloses a pyraclostrobin and prothioconazole compound suspending agent and application thereof, and belongs to the technical field of pesticides. The suspending agent is prepared from pyraclostrobin, prothioconazole, auxiliaries and the balance of water, wherein the weight ratio of active components pyraclostrobin and prothioconazole is (1.0 to 2.5) to 1, and is preferably (1.2 to 2.0) to 1. Conventional auxiliaries comprise a wetting agent, a dispersing agent, a rain drop erosion resisting agent, an anti-freezing agent, a thickening agent, an antifoaming agent and a preservative; special auxiliaries comprise a stabilizing agent and a nano clathrate compound carrier. The suspending agent prepared from a bactericidal composition, which is provided by the invention, has advantages of being excellent in prevention and treatment effects when being used for preventing and treating a fusarium caused disease, particularly for preventing and treating wheat scab, and further, being obvious in synergism, high in storage stability and resistant to rain drop erosion, and the like, can effectively protect a crop from being suffered from a disease for a long time, and is convenient to use by a peasant; the labor cost is reduced.

Description

technical field [0001] The invention relates to a compound bactericidal composition and its application, belonging to the technical field of pesticides. Background technique [0002] Pyraclostrobin, English name (Pyraclostrobin), chemical name: N-{2[1-(4-chlorophenyl)-1H-pyrazol-3yloxymethyl]phenyl} (N-methoxy ) methyl carbamate, an inhibitor of mitochondrial respiration. It can prevent and eliminate all types of fungal pathogens, and has a wide bactericidal spectrum. Despite the unique mechanism of action of this fungicide, like other fungicides, the doom of resistance is inevitable. [0003] Prothioconazole, English name (prothioconazole), chemical name: 2-[(2RS)-2-(1-chlorocyclopropyl)-3-(2-chlorophenyl)-2-hydroxypropyl]-2H -1,2,4-triazole-3(4H)-thione, prothioconazole is a demethylation inhibitor (DMIs), has good systemic activity, excellent protection, treatment and eradication activity, And it has a long duration. [0004] In the actual process of agricultural pro...
