Description

Technical Field

[0001] The utility model relates to the technical field of pesticide production, in particular to a pesticide extraction device. Background Art

[0002] Pesticides refer to chemical synthesis or a mixture of several substances or their preparations that are derived from biological or other natural substances and are used to prevent and control diseases, insects, weeds, rats and other harmful organisms that endanger agriculture and forestry, as well as to purposefully regulate the growth of plants and insects. They are widely used in agriculture, forestry and animal husbandry production. According to the source of raw materials, they can be divided into organic pesticides, inorganic pesticides, botanical pesticides and microbial pesticides. Botanical pesticides refer to pesticides made from plants or their active ingredients that are toxic to other plant diseases and insect pests. The active ingredients contained in pyrethrum, derris and tobacco are pyrethrin, rotenone, nicotine, etc. This type of pesticide is not only safe for humans and animals, but also does not pollute the environment. Therefore, this type of pesticide is one of the key points of future development. Botanical pesticides are mainly extracted from rhizomes and branches and leaves, which are difficult to squeeze directly and need to be crushed in advance. The process is complicated and the efficiency is not high. Utility Model Content
