Embodiment 1

[0035] ⑴Take neem 100kg, tripterygium wilfordii 80kg, chili pepper 30kg, tobacco leaves 10kg.

[0036] (2) Use a universal pulverizer to pulverize all the raw materials above into 30-40 mesh coarse powder for later use.

[0037] (3) In the mixed powder obtained in step (2), add 16 times the weight of 95% ethanol solution to extract the active ingredients of the crude drug for 3 hours, then use ultrasonic treatment to extract for 1 hour, and then feed the steam to distill the solvent to concentrate the medicinal solution, and the medicinal solution is concentrated Until the relative density of the medicinal solution is 1.1 to 1.2;

[0038] (4) Place the concentrated medicinal solution obtained in step (3) in a blending kettle, add commercially available Nongru 2201 to make the additive content reach 15% of the weight of the mixed solution, and obtain the plant insecticide after fully stirring, and finally put it into the high-level tank Precipitation and filling.

Embodiment 2

[0040] (1) Take 50kg of neem seeds, 40kg of tripterygium wilfordii, 70kg of chili pepper, and 60kg of tobacco leaves.

[0041] (2) Use a universal pulverizer to pulverize all the raw materials above into 30-40 mesh coarse powder for later use.

[0042] (3) Add 16 times the weight of 95% ethanol solution to the mixed powder obtained in step (2) to extract the active ingredients of the crude drug for 3 hours, then use ultrasonic treatment to extract for 2 hours, then feed the steam to distill the solvent to concentrate the medicinal solution, and the medicinal solution is concentrated Until the relative density of the medicinal solution is 1.1 to 1.2;

[0043] (4) Place the concentrated medicinal solution obtained in step (3) in a blending kettle, add commercially available Nongru 2201 to make the additive content reach 15% of the weight of the mixed solution, and obtain the plant insecticide after fully stirring, and finally put it into the high-level tank Precipitation and fi...

Embodiment 3

[0045] (1) Take 100kg of neem seeds, 80kg of tripterygium wilfordii, 40kg of chili pepper, and 60kg of tobacco leaves.

[0046] (2) Use a universal pulverizer to pulverize all the raw materials above into 30-40 mesh coarse powder for later use.

[0047] (3) Add 16 times the weight of 95% ethanol solution to the mixed powder obtained in step (2) to extract the active ingredients of the crude drug for 3 hours, then use ultrasonic treatment to extract for 2 hours, then feed the steam to distill the solvent to concentrate the medicinal solution, and the medicinal solution is concentrated Until the relative density of the medicinal solution is 1.1 to 1.2;

[0048] (4) Place the concentrated medicinal solution obtained in step (3) in a blending kettle, add commercially available Nongru 2201 to make the additive content reach 15% of the weight of the mixed solution, and obtain the plant insecticide after fully stirring, and finally put it into the high-level tank Precipitation and f...

Abstract

The invention relates to an efficient plant pesticide and a preparation method thereof. The efficient plant pesticide is prepared from, by weight, 50-100 parts of Chinaberry seeds, 50-100 parts of pomegranate bark, 50-100 parts of glossy privet fruits, 40-80 parts of thunder god vine, 30-70 parts of pod peppers and 10-60 parts of tobacco leaves. The raw materials are extracted, concentrated and mixed with an additive to obtain the plant pesticide. The pesticide has the advantages of being simple in production technology, wide in material source, capable of using local materials, low in cost, capable of saving the cost and safe for human, livestock and crops; the plant pesticide is easy to decompose when sprayed on the crops, avoids residual toxicity, reduces environmental protection and has the unique insecticidal effect on brevicoryne brassicae and cabbage caterpillar particularly. In addition, the plant pesticide has the effect of stimulating crop growth, is beneficial to growth and development of crops and increases yield.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a high-efficiency plant insecticide and a preparation method thereof. Background technique [0002] The use of botanical pesticides to control diseases and insect pests has a history of 1,500 years in my country, and there is a record of using herbal medicines to kill insects in "Compendium of Materia Medica". According to investigations and research, there are more than 200 kinds of plants that can be processed into natural herbal medicines for preventing and controlling agricultural, forestry, fruit and vegetable crops diseases and insect pests.
