Pure natural insecticide extracted from plants

Abstract

The invention discloses a pure natural insecticide extracted from plants. The insecticide is prepared from the following raw materials in parts by weight: 18-23 parts of melia azedarach bark, 12-18 parts of tea saponin, 0.01-0.03 part of isopropyl palmitate, 10-15 parts of garlic, 8-12 parts of rhododendron molle, 7-16 parts of lemon, 10-20 parts of hydrogen peroxide, 13-16 parts of citronella, 8-20 parts of Chinese prickly ash water, 0.005-0.015 part of polyglyceryl-3 polyricinoleate and 6-14 parts of glycine. Compared with the prior art, the insecticide provided by the invention has the advantages that various plant extracts are used as main raw materials, various harmful bacteria, viruses and insect pests can be effectively killed, and simultaneously the environment is completely free from pollution. After a small amount of the isopropyl palmitate is mixed with the polyglyceryl-3 polyricinoleate, the mixture can be combined with the substances such as the melia azedarach bark, the citronella and the like, so certain bactericidal and sterilizing effects can be exerted. The preparation process is simple, the raw materials are cheap, and the insecticide is suitable for large-scaleproduction.

Description

technical field [0001] The invention relates to the field of chemical pesticides, in particular to a plant-extracted pure natural pesticide. Background technique [0002] For thousands of years, people have used various methods to protect their crops from diseases, insects and other harmful organisms, among which the use of pesticides is one of the most effective methods. Most of the early pesticides came from plants. The "Chinese Soil Pesticides" published by China Agricultural Publishing House recorded in detail that 220 plants in 86 families had agricultural activities. After the 1940s, chemically synthesized pesticides became popular due to their high efficiency, quick effect, and wide insecticidal spectrum, which caused the research and use of botanical pesticides to fall into a slump. However, with the use of chemical pesticides, its disadvantages have gradually emerged, such as the three "R" problems (residue, drug resistance, and re-emergence of pests). Botanical p...

Problems solved by technology

The fatal disadvantages of these pesticides are: the smell is strong and unpleasant, and it is easy to endanger the safety of humans and animals, and seriously affect the sanitation and safety of the environment including water resources.

There are many types of raw materials required for the production of pesticides in the prior art, and the production cost is relatively high, resulting in poor economic benefits for pesticide manufacturers and high costs for users to use pesticides
