Embodiment 1

[0014] Embodiment 1: take aconitine 0.1kg, then with alkylphenol polyoxyethylene ether phosphate 8.0kg, sulfosuccinic acid di-second-octyl sodium salt 4.9kg, isopropanol 14.0kg and urea 2.0kg at high speed After stirring and mixing in a shearing machine, finally add 70.5 kg of deionized water, stir and mix evenly, let stand for 5 hours, heat to 40° C., and fully stir to prepare aconitine plant source insecticidal microemulsion. Use 800 times of this preparation to carry out the field drug efficacy test, and the control effects on the 7th day, 14th day and 21st day after the application of the drug to the potato beetle were 90.8%, 91.7% and 88.1%, respectively; The control effects of days and 12 days were 91.1%, 92.9% and 90.3%, respectively.

Embodiment 2

[0015] Embodiment 2: take by weighing aconitine 60.0kg, then with natural carboxylate 3.0kg, alkylphenol polyoxyethylene ether phosphate 2.0kg, biphenol polyoxyethylene ether 4.5kg, sulfosuccinic acid di-sec-octyl 3.5kg of sodium salt, 5.0kg of ethylene glycol, and 2.0kg of potassium dihydrogen phosphate were stirred and mixed evenly in a high-speed shearing machine, and finally 20.0kg of deionized water was added, stirred and mixed evenly, allowed to stand for 9 hours, and heated to 55°C. After fully stirring, the aconitine plant source insecticidal microemulsion can be prepared. Use this preparation 3000 times liquid to carry out the field efficacy test, the control effect to the potato beetle on the 7th day, 14 days and 21 days after the application is respectively 95.8%, 96.7% and 89.6%, to the green peach aphid on the 3rd day, 9 days after the application. The control effects of days and 12 days were 97.1%, 97.9% and 96.3%, respectively.

Embodiment 3

[0016] Embodiment 3: take aconitine 15.0kg, then with biphenol polyoxyethylene ether 4.5kg, dioctyl sulfosuccinate sodium salt 4.0kg, octyl phosphate sodium salt 2.5kg, ethyl acetate 4.0kg 1. Sodium sorbate 3.0kg, stir and mix evenly in a high-speed shearing machine, finally add 67.0kg of deionized water, stir and mix evenly, let stand for 5 hours, heat to 47°C, after fully stirring, aconitine can be made Insecticidal microemulsion of plant origin. Use 2500 times of this preparation to carry out the field efficacy test, and the control effects on the 7th day, 14th day and 21st day after the application of the drug to the potato beetle were 92.8%, 93.7% and 89.6%, respectively; The control effects of days and 12 days were 94.1%, 95.9% and 933%, respectively.

Abstract

The invention discloses an aconitine plant source insecticidal micro emulsion and a preparation method thereof. The aconitine plant source insecticidal micro emulsion comprises the following components in percentage by weight: 0.1-60 percent of aconitine, 3-27 percent of emulsifying agent, 2-15 percent of penetrating agent, 1-10 percent of stabilizing agent, 2-40 percent of cosolvent and 15-76 percent of deionized water. The preparation method of the aconitine plant source insecticidal micro emulsion comprises the following steps of: stirring and uniformly mixing the aconitine with the emulsifying agent, the penetrating agent, the cosolvent and the stabilizing agent in a high-speed shearer; adding the deionized water; stirring and uniformly mixing; standing for 5-15 hours and heating to 40-60 DEG C; and fully mixing to obtain the aconitine plant source insecticidal micro emulsion. The aconitine plant source insecticidal micro emulsion has remarkable effect for potato beetle, peach-potato aphid and other pests, has no harm and pollution to the environment, is not easy to generate the pesticide damage, has low cost and simple preparation process and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to a botanical pesticide insecticide, in particular to an aconitine botanical insecticidal microemulsion and a preparation method thereof, belonging to the technical field of pesticides. Background technique [0002] Chemical pesticides have made great contributions to agricultural harvests, but they have also caused serious pollution to the natural environment, which has aroused widespread concern. Especially in today's increasingly perfect and strict requirements of environmental protection laws and regulations, the call for reducing pesticide pollution is getting stronger and stronger. In recent years, in countries such as the United States, restrictions on the use of organic solvents in pesticide formulations have become increasingly stringent, and xylene has a tendency to be banned in some countries. Therefore, it has become the general trend of pesticide development to develop new liquid preparations with strong safety, gre...
