Problems solved by technology

[0004] However, the general botanical pesticides, due to the simple and rough preparation method, make the active ingredients of the drug complex and difficult to detect, the drug effect is not easy to stabilize, and the insecticidal effect is slow
Moreover, it is not easy to combine with other pesticides based on its drug action mechanism to improve drug efficacy or expand the research and application of insecticidal spectrum.

Embodiment 1

[0037] The pepper raw material (the fruit of the pepper tree) is washed, crushed, ground, soaked in methanol (the weight ratio of the pepper raw material to methanol is 1:2-8), and then extracted with dibutyl ester for many times, and the extract is extracted at a temperature of 60 Concentrate at ℃ for 8 hours, and concentrate to a liquid extract, which is separated and purified by thin-layer lamination to obtain piperine.

[0038] Add 50Kg of piperine, 2Kg of artemisinin, 3Kg of cinnamonalool, and 27Kg of organic solvent into a mixer mixing kettle with a thermometer, until the temperature reaches 80°C, mix under stirring for 8 hours, add 13Kg of surfactant, aminoketone 1Kg, stabilizer 3Kg, preservative 1Kg, PH regulator 0.2Kg, mix and stir evenly, obtain the piperine insecticide product.

Embodiment 2

[0040] Wash and crush the pepper raw materials (fruits and leaves of the pepper tree), soak them in ethanol (the weight ratio of the pepper raw materials to ethanol is 1:2-8), and then use acetone for multiple extractions; Concentrate for 5 hours, and concentrate to a liquid extract, which is separated and purified by thin-layer lamination to obtain piperine.

[0041] Put 60Kg of piperine and 40Kg of organic solvent into the mixer mixing kettle with a thermometer until the temperature reaches 60°C, mix under stirring for 6 hours, add 15Kg of surfactant, 1Kg of synergistic phosphorus, 4Kg of stabilizer, and 1Kg of preservative , PH regulator 0.1Kg, mix and stir evenly, obtain the piperine insecticide product.

Embodiment 3

[0043] Pepper raw materials (fruits or leaves of pepper trees) are cleaned, crushed, soaked in white wine (the weight ratio of pepper raw materials to white wine is 1:2-8), and then extracted with dioctyl ester for many times, and the extract is heated at a temperature of 90 Concentrate at ℃ for 3 hours, and concentrate to a liquid extract, which is separated and purified by thin-layer lamination to obtain piperine.

[0044] Put 40Kg of piperine, 10Kg of camphor ferment, and 50Kg of organic solvent into a mixer mixing tank with a thermometer, until the temperature reaches 90°C, mix under stirring for 4 hours, add 16Kg of surfactant, 0.5Kg of DHS activator, and stabilize 10Kg of antiseptic, 0.7Kg of antiseptic, 0.3Kg of pH regulator, mix and stir, obtain the piperine insecticide product.

Abstract

The invention discloses a piperine pesticide and its preparation method. The pesticide comprises 13-70 parts of piperine, 0-6 parts of artemisinin, 0-17 parts of linalool, 0.1-3 parts of synergist, 3-11 parts of stabilizing agent, 11-16 parts of surfactant, 0.2-3 parts of preservative, 13-60 parts of organic solvent and 0.4-7 parts of pH regulator by weight. The piperine is acquired from milled and immersed fruit and / or leaves of pepper tree through organic solvent extraction method or other existing extraction methods; the piperine, the artemisinin and / or the linalool and the organic solvent which are proportioned by weight are added into the mixing tank, heated to 20-100 DEG C while stirring and mixing for 3-12 hours, and then evenly mixed with other raw materials so as to acquire the cream preparation; the pesticide can be also produced into other dosage forms through existing plant source pesticide preparation methods. The piperine pesticide has great insect killing and controlling effect for wheat, rice, fruit tree, vegetable, flower and forest tree.

Description

technical field [0001] The invention belongs to the field of botanical biological pesticides, and in particular relates to a piperine pesticide and a preparation method thereof. Background technique [0002] The use of biological characteristics, that is, certain components contained in plants, has existed since ancient times to prevent and control crop diseases and insect pests. As early as the end of the Eastern Han Dynasty, my country’s first pharmacy monograph "Shen Nong’s Materia Medica" and "Compendium of Materia Medica" by Li Shizhen in the Ming Dynasty had very detailed descriptions of the understanding and application of certain ingredients of plant characteristics. In many ancient monographs on pharmacy, our ancestors mentioned that Artemisia annua, Cortex Phellodendron, Zigonia, and Guanzhong all have insecticidal properties. [0003] In order to increase the production and income of agricultural crops, a large number of chemical pesticides have been used in agri...
