Example Embodiment

[0043] Example 1:

[0044] Formula: 20g fenpropathrin, 1g emamectin benzoate, 10g fatty alcohol polyoxyethylene ether, 5g alkylphenol formaldehyde resin polyoxyethylene, add water to 100g.

[0045] Preparation method: Weigh 20g (based on active ingredients, the same below) fenpropathrin technical, 1g emamectin benzoate, 10g fatty alcohol polyoxyethylene ether, 5g alkylphenol formaldehyde resin polyoxygen Ethylene was mixed, stirred for 0.5 h at a rotation speed of 85 revolutions / sec, kept stirring, 64 g of water was added, and stirring was continued for 1 h to obtain 21% fenpropathrin·methylaminoabamectin benzoate nano-aqueous solution.

[0046] The nano-aqueous agent of this example has a transparent and slightly yellow appearance, a viscosity of 180 mPa·s, and an average particle size of 12.0 nanometers.

[0047] After the nano-aqueous agent of this example was stored at 0°C for 7 days and 54°C for 14 days, there was no precipitation phenomenon, and it was still stable.

Example Embodiment

[0049] Example 2:

[0050] Formula: 10g fenpropathrin, 1g methylaminoabamectin benzoate, 3g styrylphenol polyoxyethylene ether, 3g fatty alcohol polyoxyethylene ether, 2g alkylphenol formaldehyde resin polyoxyethylene ether, Add water to 100g.

[0051] The preparation method is the same as that of Example 1, and 11% fenpropathrin·aminoabamectin benzoate nano-aqueous agent is prepared.

[0052] The nano-aqueous agent of this example has a transparent and slightly yellow appearance, a viscosity of 195 mPa·s, and an average particle size of 13.6 nanometers.

[0053] After the nano-aqueous agent of this example was stored at 0°C for 7 days and 54°C for 14 days, there was no precipitation phenomenon, and it was still stable.

[0054] After entering water, the nano-aqueous agent of this embodiment can quickly dissolve with water to form a completely transparent solution, and the dilution stability is qualified.

[0055] Example 3:

[0056] Formula: 5g fenpropathrin, 1g emamectin benzoate, 1g alkylphenol formaldehyde resin polyoxyethylene ether, 3g fatty alcohol polyoxyethylene ether sodium sulfate, add water to 100g.

[0057] The preparation method was the same as that in Example 1, and 6% fenpropathrin·aminoabamectin benzoate nano-water was prepared.

[0058] The nano-aqueous agent of this embodiment has a transparent and slightly yellow appearance, a viscosity of 185 mPa·s, and an average particle size of 18.5 nanometers.

[0059] After the nano-aqueous agent of this example was stored at 0°C for 7 days and 54°C for 14 days, there was no precipitation phenomenon, and it was still stable.

[0060] After entering water, the nano-aqueous agent of this embodiment can quickly dissolve with water to form a completely transparent solution, and the dilution stability is qualified.

Abstract

The invention discloses a composite insecticidal and acaricidal nano aqueous solution containing fenpropathrin and emamectin benzoate. The insecticidal composition takes fenpropathrin and emamectin benzoate as insecticidal and acaricidal active ingredients, and comprises the following components in percentage by weight: 3 to 25 percent of fenpropathrin and emamectin benzoate, 5 to 20 percent of apesticide adjuvant and the balance of water. The weight ratio of the fenpropathrin to the emamectin benzoate is 20:1-1:20. The nanoscale micelle formed by the surfactant is used for bearing fenpropathrin and emamectin benzoate which are insoluble in water, and the active components exist in the nano aqueous solution in the form of nanoscale particles, so that the nano aqueous solution is beneficial to attachment, spreading and permeation on a target and is more resistant to rain wash. The two effective components can generate a synergistic effect, lepidoptera pests and mite pests on crops canbe prevented and treated, the insecticidal speed is high, the lasting period is long, and the prevention and treatment effect is obviously higher than that of a single agent.

Description

technical field [0001] The invention belongs to the field of pesticides, and relates to a compound insecticidal and acaricidal nano-water agent containing fenpropathrin and emamectin benzoate and its application. Background technique [0002] Fenpropathrin, chemical name: 2-cyano-3-phenoxybenzyl-2,2,3,3-tetramethylcyclopropanoate. High-efficiency, broad-spectrum pyrethroids with contact and repellent effects, as well as stomach toxicity. In addition to the general synthetic pyrethrin properties, it has good effects on a variety of crop spider mites, so it has the advantage of killing both insects and mites. Highly effective against Lepidoptera larvae and effective against Diptera or Hemiptera pests. It can be used to control pests on cotton, fruit trees, vegetables, tea and flowers. [0003] Emamectin Benzoate, referred to as emamectin benzoate, molecular formula: C 56 h 81 NO 15 . Chemical name: 4'-epi-methylamino-4'-deoxyabamectin B1 benzoate. Emamectin benzoate is...
