Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with embodiment:

[0018] The technical scheme recorded in the present invention is: a kind of azadirachtin insecticide, containing azadirachtin, characterized in that it contains 0.3-1.0% azadirachtin powder by weight, 40-60% Tween 85, and the rest is vegetable oil.

[0019] The azadirachtin raw powder preferably contains 28-40% azadirachtin, and the azadirachtin is effective everywhere as long as the purity of the azadirachtin is within the range of 28-40%. At the same time, the higher the purity, the better the insecticidal effect.

[0020] Described vegetable oil is sesame oil, soybean oil, castor oil, rapeseed oil, preferably sesame oil.

[0021] Concrete embodiment such as following table:

[0022] ingredients Azadirachtin powder (%) Tween 85(%) Sesame, soybean, castor or canola oil (%) Example 1 0.3 40 The rest is made up to 100% with one of the abov...

Abstract

The invention relates to an azadirachtin insecticide, which contains azadirachtin and is characterized by comprising the following components in percentage by weight: 0.3 to 1.0 percent of azadirachtin raw powder, 40 to 60 percent of Tween 85 and the balance of vegetable oil. A method for preparing the azadirachtin insecticide is characterized by comprising the following steps of: 1, preparing the following materials in percentage by weight: 0.3 to 1.0 percent of azadirachtin raw powder, 40 to 60 percent of Tween 85 and the balance of vegetable oil; 2, adding 40 to 60 percent of Tween 85 into a reactor, heating gradually, and adding the azadirachtin raw powder slowly for three to four times at the temperature of less than or equal to 45 DEG C; and 3, dissolving the azadirachtin raw powder, and adding the vegetable oil until the total amount is 100 percent and mixing uniformly. When the technical scheme is adopted, the defect of the prior art at least can be overcome, and the adverse effect of the azadirachtin insecticide on environment and human and livestock can be reduced effectively.

Description

technical field [0001] The invention relates to an azadirachtin insecticide and a preparation method thereof. Background technique [0002] Azadirachtin can reduce the number of blood cells in insects, reduce the protein content in hemolymph, reduce the concentration of trehalose and metal cations in hemolymph, and can inhibit insect midgut esterase and protease, amylase, lipase, phosphatase and The activity of glucose enzymes can reduce the feeding rate of insects and the conversion and utilization rate of food, can affect the normal breathing rhythm of insects, reduce the content of DNA and RNA in the fat body of insects, and reduce the protein and sugar in ovaries, oviducts and seminal vesicles of female insects. The content of progeny and lipids and the activity of some enzymes have an impact on the reproductive system of male insects, causing lesions in the brain, pharyngeal body, cardiac side body, prothymus, fat body, etc. of insects, affecting the balance of hormones...
