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...
