Problems solved by technology

The insecticide is synthesized by natural plants and does not contain any toxic chemical components. After spraying, there is no residual toxin on plants, fruit trees and vegetables, and it is harmless to human and environmental water resources. It can replace the existing chemical pesticides. It is a new type of insecticide. The pollution-free and environmentally friendly green insecticide, but the preparation method of the insecticide cannot fully release the active ingredients of each raw material, and there is still room for improvement in the efficacy of the insecticide

Embodiment 1

[0013] The preparation method of an edible apple fruit tree insecticide comprises raw material pretreatment, microwave extraction, and finished product preparation, and specifically includes the following steps:

[0014] 1) Raw material pretreatment: take raw materials according to the following parts by weight: 23 parts of baeba, 21 parts of tobacco leaves, 21 parts of oil tea leaves, 18 parts of Galla chinensis, 15 parts of Cnidium chinensis, 13 parts of bitter bark vine, 1.5 parts of garlic, 1.5 parts of ginger, 0.8 parts of red pepper, 1 part of custard apple, 2.5 parts of Polygonum, 2.5 parts of poisonous lentils, first crushed by a mechanical pulverizer to 20-30 mesh, and then ultrafinely pulverized to 4-7μm under 1.5MPa to obtain superfine powder , standby, in this step, ultrafine pulverization can destroy the cell wall of Chinese herbal medicine, and the cell wall breaking rate is not less than 95%, so that the effective drug components in the cells are fully exposed, a...

Embodiment 2

[0018] The preparation method of edible apple fruit tree insecticide specifically comprises the following steps:

[0019] 1) Take the raw materials according to the following parts by weight: 22 parts of Baibu, 22 parts of tobacco leaves, 18 parts of oil tea leaves, 22 parts of Galla chinensis, 13 parts of Cnidium chinensis, 15 parts of bitter bark vine, 1.7 parts of garlic, 1.2 parts of ginger, and 0.7 parts of red pepper , 0.8 parts of custard apple, 2 parts of Polygonum, and 3 parts of poisonous lentils, initially crushed to 20-30 mesh, and then ultrafinely pulverized to 4-7 μm under 1.3MPa to obtain ultrafine drug powder, which is set aside. The crushing can destroy the cell wall of Chinese herbal medicine, and the cell wall breaking rate is not less than 95%, so that the effective drug components in the cells are fully exposed. The smaller particle size of the powder can increase the contact area between the powder and water, increase the extraction rate, and shorten the e...

Embodiment 3

[0023] The preparation method of edible apple fruit tree insecticide, the specific steps are: take 25 parts of basil, 19 parts of tobacco leaves, 23 parts of oil tea leaves, 17 parts of Galla chinensis, 17 parts of Cnidium chinensis, 10 parts of bitter bark vine, 2 parts of garlic, ginger 1 part, 0.5 parts of red pepper, 1.4 parts of custard apple, 2.6 parts of Polygonum, 2.2 parts of poisonous lentils, initially pulverized to 20-30 mesh, and then ultrafinely pulverized to 4-7μm under 1.7MPa to obtain superfine powder. Add water to the ultra-fine drug powder with a material-liquid ratio of 1:12, then add active peptides with a weight of 0.008% of the ultra-fine drug powder, mix evenly, extract by microwave at a microwave power of 200W for 18 min, cool to room temperature, and collect the supernatant by centrifugation. The extract is obtained; then the extract is distilled and concentrated to 60% of the total drug amount, and α-terpineol with a drug weight of 0.2% is added. In α...

Abstract

A preparing method of an edible apple tree pesticide is disclosed. The method includes weighing stemona root, tobacco eaves, oil tea leaves, Chinese gall, common cnidium fruit, celastrus angulatus, garlic, fresh ginger, hot pepper, sugar-apple, polygonum hydropiper L., and physostigma venenosum Balf. according to prescription amounts, primarily crushing the weighed raw materials, then performing ultramicro-pulverization, adding water and active polypeptide into the pulverization product, performing microwave extraction, performing centrifugation, collection a liquid supernatant, distilling and concentrating the obtained liquid supernatant, then adding alpha-terpilenol into a concentration product, fully mixing the mixture and performing filling operation to obtain the pesticide. Beneficial effects of the pesticide are that the components of the pesticide are derived from plants so that the pesticide is free of medicine residues after the pesticide is sprayed, picked apples can be directly eaten, the pesticide is nontoxic to human bodies, and a safe effective novel variety for production of green foods is provided; the pesticide can rapidly kill common pests of apple trees and drug resistance is not generated; the preparing method is simple, safe, energy-saving, and pollution-free; production equipment is simple; and investment is saved.

Description

technical field [0001] The invention relates to the technical field of insecticides, in particular to a preparation method of an edible apple fruit tree insecticide. Background technique [0002] Insecticides are primarily a class of pesticides used to control agricultural pests. At present, organophosphorus insecticides are the most widely used insecticides with many product varieties, ranking the first in terms of output, and these insecticides are usually made by chemical synthesis. The advantages of insecticides are fast, but the pesticide residues are large, and long-term consumption of foods that have been applied with such pesticides will cause chronic toxicity to the human body, especially delayed neurotoxicity, which has threatened the living environment of human beings. With the rapid development of my country's economy in recent years, people's food safety awareness has gradually increased, and the voice of "green food" has become higher and higher. In addition,...
