Abstract
The invention provides a preparation method of a green herbal insecticide, comprising the following steps: (1) cutting three raw materials of paris polyphylla root tubers, camphor and areca inflorescence into slices according to the weight ratio of 1:0.8-1.2:6.0-7.0, and then soaking the slices into industrial alcohol to obtain a soak solution; (2) pulverizing four raw materials of tripterygium glycoside, clematis root, large stemona root collars and fruit of Rangoon creeper, and then fumigating the pulverized raw materials based on the weight ratio of 1:0.8-1.2:0.8-1.2:1.5-2.5 at the temperature of 150-250 DEG C by hot steam to obtain a fumigation solution, wherein the weight ratio of the tripterygium glycoside to the paris polyphylla root tubers in step (1) is 1.5-2.5:1; and (3) mixing the soak solution with the fumigation solution to obtain the green herbal insecticide. The components of the green herbal insecticide are extracted from natural Chinese traditional medicines or plants, thus the green herbal insecticide has no harm to human body and environment, has aromatic odor and insecticidal lethality, can repel pests and go deep into the internal organs of the pests to kill the pests, and has great killing action on various insects.
Description
technical field [0001] The invention relates to a preparation method of a pollution-free green insecticide synthesized by various herbs. technical background [0002] According to the results of the current international investigation and inspection of crops and by-products, there are generally chemical pesticide residues. The previously used 666, 1059, 1605, dichlorvos, etc. have all detected residues of antimony agents and organophosphorus pesticides. Therefore, the pesticide residues commonly used in the past have a long residual period and are not easy to decompose, and it is easy to cause poisoning of sprayers and eaters. Tens of thousands of users and eaters are poisoned and die every year in all countries in the world. The environment and water resources cause serious pollution, and lead to the occurrence of various diseases and even cancer of the eaters. All countries in the world have invested huge sums of money in scientific research on non-toxic pesticides, and f...
