[0030] Preparation:

[0031] (1) Cyhalothrin, spinosad, egg yolk lecithin and Tween 80 are added to soybean oil, mixed evenly, to obtain an oil phase solution;

[0032] (2) under stirring conditions, the above-mentioned oil phase solution is added into water to obtain an oil-water mixture;

[0033] (3) Add n-butanol, matrine and nano-titanium dioxide into water to dissolve, slowly add it dropwise into the above-mentioned oil-water mixture, and control the temperature of the oil-water mixture to be 40°C;

[0034] (4) After the dropwise addition, 400W ultrasonic for 15min, the solution is transparent, and it is ready.

[0035] The average particle diameter of the obtained nanoemulsion insecticide is 80nm.

[0039] Preparation:

[0040] (1) Cyhalothrin, spinosad, egg yolk lecithin and Tween 80 are added to soybean oil, mixed evenly, to obtain an oil phase solution;

[0041] (2) under stirring conditions, the above-mentioned oil phase solution is added into water to obtain an oil-water mixture;

[0042] (3) Add n-butanol, matrine and nano-titanium dioxide into water to dissolve, slowly add it dropwise to the above-mentioned oil-water mixture, and control the temperature of the oil-water mixture to be 35°C;

[0043] (4) After the dropwise addition, 300W ultrasonic for 10min, the solution is transparent, and it is ready.

[0044] The average particle diameter of the obtained nanoemulsion insecticide is 70nm.

Abstract

The invention discloses a nano emulsion pesticide. The nano emulsion pesticide is mainly prepared from the following raw materials in parts by weight: 1 part of cyhalothrin, 0.1-0.5 part of pleocidin, 0.2-0.8 part of sophocarpidine, 10-20 parts of nano-titanium dioxide, 200-300 parts of soybean oil, 50-70 pars of egg yolk lecithin, 10-16 parts of n-butyl alcohol and 0.1-0.5 part of Tween-80. The invention also provides a preparation method of the nano emulsion pesticide. Compared with the prior art, the nano emulsion pesticide prepared by adopting the method is low in cost, simple in process, long in persistent effect period and low in damage to the ecosystem; a relatively strong insecticidal effect can be achieved by using a relatively low amount of the pesticide.

Description

technical field [0001] The invention relates to a nanoemulsion insecticide containing multiple active ingredients and a preparation method thereof, belonging to the field of pesticides. Background technique [0002] Insecticides are mainly used to control agricultural pests and urban sanitation pests. They have a long history of use, large amounts, and many varieties. In the 20th century, with the rapid development of agriculture, pesticides greatly increased agricultural output. However, almost all pesticides seriously alter the ecosystem, most are harmful to humans, and others are concentrated in the food chain. We must strike a balance between agricultural development and the environment and health. Therefore, it is worth further research to find insecticides with excellent insecticidal effect and the least damage to the ecosystem. [0003] At present, the existing insecticides are not only weak in insecticidal effect and poor in durability, but also seriously damage t...
