Problems solved by technology

[0002] At present, most of the pesticides used in China are chemical pesticides. The use of chemical pesticides not only pollutes the environment, but also leaves animals and plants in the body and causes damage to humans after long-term use. At the same time, animals and plants are prone to develop drug resistance; In addition, although there are studies and reports on plant pesticides, they generally have the characteristics of slight toxicity, slight residue and slow effect.

Embodiment Construction

[0009] When preparing, the Chinese herbal medicine plants should be selected first, and each raw material should be pure dry product to avoid mildew, moth-eaten, discoloration, staleness, deterioration and other fake and inferior products, that is, the raw materials are selected according to the routine.

[0010] The preparation process of the tobacco concentrate is as follows: the raw materials are air-dried or dehydrated and air-dried in other ways and then pulverized into 1-6 mm, strips, sheets or other shapes, and the pulverized raw materials are soaked in water with a temperature above 20 ° C for 20-48 hours. The weight ratio with water is 1: 4, then dewatering with a centrifuge, the filter press squeezes out the active ingredient with a specific gravity of 0.02-0.04 of 2800-3000 purpose, and then the filtrate is concentrated and refined in the reactor for 3-4 hours, and the temperature is 90 ℃. -110°C, that is, a concentrated solution with a specific gravity of 0.04-0.11 ...

Abstract

The invention relates to an insecticide and a preparation method thereof, particularly a botanical insecticide and a preparation method thereof. The insecticide is mainly prepared from the following Chinese herbal medicine protophyte extracts in percentage by weight: 50-75% of tobacco leftover, 2-5% of croton oil, 2-5% of Melia toosendan, 2-5% of wild chrysanthemum flower, 2-5% of pod pepper, 5-10% of arum, 5-10% of gingko exopleura and 5-10% of derris, wherein the tobacco leftover comprises the following components in percentage by weight: 64% of tobacco leaf, 18% of tobacco stem, 13% of tobacco root and 5% of tobacco flower. The invention has the following advantages: 1. the comprehensive insecticidal rate is high; 2. the application isolation period reaches about 15 days, thereby lowering the agricultural production cost; 3. no three wastes are produced in the production process, residues used as the fertilizer can be used for killing insects, the insect control rate for Chinese chive maggots is up to 95%, and the residues can also relieve sealing of soil and loosen the soil; and 4. no insecticide remains on crops.

Description

Technical field: [0001] The invention relates to an insecticide and a preparation method, in particular to a plant insecticide and a preparation method thereof. Background technique: [0002] At present, most of the pesticides used in China are chemical pesticides. The use of chemical pesticides not only pollutes the environment, but also causes damage to humans due to residues in animals and plants after long-term use. In addition, although there are studies and reports on plant insecticides, there are generally the characteristics of micro-toxicity, micro-residue and slow effect. Invention content: [0003] The purpose of the present invention is to provide a high-efficiency, prescription, sub-low toxicity, no residue plant pesticide and a preparation method thereof. The raw materials of the pesticide are completely taken from natural plants, and the production process is a physical change process, and no pollutants such as waste water and waste residue are produced. ...
