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
It is not easy to combine with other pesticides based on its drug action mechanism to improve the efficacy or expand the research and application of insecticidal spectrum

Embodiment 1

[0039] After washing, crushing and grinding the raw material of Zanthoxylum bungeanum (the fruit of the Zanthoxylum bungeanum), soak it in methanol (the weight ratio of the raw material of Zanthoxylum bungeanum and methanol is 1:2-8), and then extract it with dibutyl ester for many times, and extract the extract 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 xanthoxylin.

[0040] Put 50Kg of xanthoxylin, 2Kg of artemisinin, 3Kg of linalool, and 27Kg of organic solvent into an agitator mixing kettle with a thermometer, until the temperature reaches 80°C, mix under stirring for 8 hours, add 13Kg of surfactant, azone 1Kg, stabilizer 3Kg, antiseptic 1kg, pH regulator 0.2Kg, mix and stir evenly, obtain the xanthoxylin insecticide product.

Embodiment 2

[0042] Wash and crush the raw materials of Zanthoxylum bungeanum (fruits and leaves of Zanthoxylum bungeanum), soak in ethanol (the weight ratio of raw materials of Zanthoxylum bungeanum and ethanol is 1:2-8), and then use acetone to extract multiple times; extract the solution at a temperature of 80°C Concentrating for 5 hours, concentrating to a liquid extract, which is separated and purified by thin-layer lamination to obtain xanthoxylin.

[0043] Put 60Kg of Xanthophyllin and 40Kg of organic solvent into a 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 xanthoxylin insecticide product.

Embodiment 3

[0045] The raw material of Zanthoxylum bungeanum (fruit or leaf of Zanthoxylum bungeanum) is washed, crushed, soaked in mixed alcohol (the weight ratio of raw material of Zanthoxylum bungeanum and ethanol is 1:2-8), and then extracted with dioctyl ester for many times, and the extract is heated at temperature Concentrate at 90°C for 3 hours, and concentrate to a liquid extract. The extract is separated and purified by thin-layer lamination to obtain xanthanin.

[0046] Put 40Kg of xanthoxylin, 10Kg of linalool, and 50Kg of organic solvent into a mixer mixing kettle 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 evenly, obtain the xanthoxylin insecticide product.

Abstract

The suberosin pesticide consists of suberosin 13-70 (in weight portions, the same below), artemisinin 0-6, lindestrol 0-17, synergist 0.1-3, stabilizer 3-11, surfactant 11-16, preservative 0.4-7, organic solvent 13-60 and pH regulator 0.08-0.3. Suberosin is prepared with pricklyash fruit and / or leaf and through crushing, soaking, and organic solvent extraction or other extraction. The pesticide is emulsion prepared through mixing the materials in a mixing reactor while heating and stirring, and may be also prepared into other forms through available plant originated pesticide preparation process. The pesticide has obvious preventing and killing effect on several kinds of pests in wheat, rice, fruit, vegetable, flower and forest.

Description

technical field [0001] The invention belongs to the field of botanical biopesticides, and in particular relates to a xanthanin insecticide 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 agricultu...
