Embodiment 1

[0013] Example 1: Composition and preparation method of 50.0% fipronil·dimethomorph suspension concentrate

[0014] The weight percent (%) of each active ingredient in the main agent is: fipronil 45.0, dimethomorph 5.0;

[0015] The weight percentage (%) of each component of the auxiliary agent is: emulsifier, polyoxyethylene fatty acid ester 20.0; solvent, dimethylformamide 2.0, thickener, sodium carboxymethyl cellulose 5.0; stabilizer, propyl gallate 0.1; antifreeze, sorbitol, 0.1; preservatives, formaldehyde 0.1; water 22.7.

[0016] After mixing the raw materials in the above weight ratio, the traditional suspending agent processing method is used to prepare the suspending agent.

Embodiment 2

[0017] Example 2: Composition and preparation method of 27.0% fipronil·dimethomorph suspension concentrate

[0018] The weight percent (%) of each active ingredient in the main agent is: fipronil 24.0, dimethomorph 3.0;

[0019] The weight percentage (%) of each component of the auxiliary agent is: emulsifier, ethylene oxide-propylene oxide block copolymer, 10.0; solvent, methanol 6.0, ethanol 6.0; thickener, polyvinylpyrrolidone 2.0, polyethylene glycol 4.0; antifreeze, 1.0; preservatives, sodium benzoate 0.5, formaldehyde 0.1; isothiazolinone 0.7; stabilizer, 1.0; water 41.7.

[0020] After mixing the raw materials in the above weight ratio, the traditional suspending agent processing method is used to prepare the suspending agent.

Embodiment 3

[0021] Example 3: Composition and preparation method of 20.0% fipronil·dimethomorph suspension concentrate

[0022] The weight percentage (%) of each active ingredient in the main agent is: fipronil 10.0, dimethomorph 10.0;

[0023] The weight percent (%) of each component of the adjuvant is: solvent, acetone 35.0, dimethylformamide 5.0; thickener, sodium carboxypropyl cellulose 2.5, polyvinyl alcohol 2.5; antifreeze agent, polyethylene glycol 5.0; Stabilizer, epoxidized soybean oil 5.0; preservative, formaldehyde 0.2; water 24.8.

[0024] After mixing the raw materials in the above weight ratio, the traditional suspending agent processing method is used to prepare the suspending agent.

Abstract

The invention belongs to the field of pesticides and preparations thereof, and relates to an insecticidal suspending agent, in particular to a fipronil and dimethomorph blended pesticide suspending agent. The fipronil and dimethomorph blended pesticide suspending agent is characterized in that fipronil and dimethomorph serve as active ingredients of the pesticide suspending agent, and the weight ratios of the fipronil to the dimethomorph are 1:9, 1:8, 8:1 and 9:1; and the pesticide suspending agent further contains an auxiliary agent, and the auxiliary agent is prepared from the components inpercentage by weight of the total weight of the pesticide preparation: 0.1-45.0% of a solvent, 0.1-65% of an emulsifier, 0.1-6.0% of a stabilizer, 0.1-6.0% of an antifreeze agent, 0.1-6.0% of a thickener, 0.1-6.0% of a preservative, and water used for replenishing to 100.0%. The pesticide suspending agent is long in lasting period, small in environmental pollution and easy and convenient to apply.

Description

technical field [0001] The invention relates to an insecticidal suspension, in particular to a pesticide suspension mixed with fipronil and dimethomorph, and belongs to the field of pesticides and preparations thereof. Background technique [0002] The Chinese invention patent with publication date of April 7, 2013 and publication number CN 103039496 A discloses a pesticide composition, the composition contains active ingredients, and the active ingredients include thiamethoxam, thiamethoxam and thiram, The weight ratio of thiamethoxam, thiamethoxam and thiram is 1: 0.01-90: 0.01-90. The dosage forms of the above-mentioned pesticides are suspension concentrates, suspension seed coatings, wettable powders or water-dispersible granules. However, the pesticide composition adopting the above technical scheme needs three active ingredients, the preparation steps are cumbersome, and the production cost is high. Therefore, a new pesticide composition is required. Contents of th...
