Environmentally-friendly botanical pesticide and preparation method thereof

Abstract

The invention discloses environmentally-friendly botanical pesticide. The environmentally-friendly botanical pesticide is prepared from 22-26 parts of veratrum nigrum, 12-17 parts of common threewingnut root, 50-58 parts of radix sophorae flavescentis, 6-11 parts of radix euphorbiae lantu, 7-10 parts of pod pepper, 5-10 parts of tobacco leaves, 7-13 parts of Chinaberry bark and root-bark, 6-9 parts of stemona japonica, 21-25 parts of lilac daphne flower buds and 80-100 parts of ethyl alcohol. The botanical raw materials, such as the radix sophorae flavescentis, veratrum nigrum and lilac daphne flower buds, which are rich in resource and low in price are adopted, active substances with an insecticidal mechanism are extracted, the effective component (alkaloid) is separated out, and alkaloids of the radix sophorae flavescentis, veratrum nigrum and lilac daphne flower buds are prepared into a main product according to a certain proportion in a combined mode. The effective components of the botanical pesticide are pure natural substances, are degraded into non-toxic substances, are free of pollution to the environment and will not hurt a human body.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a green and environment-friendly plant insecticide and a preparation method thereof. Background technique [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...

Problems solved by technology

Some of the ways to enter the pest body are through the mouthparts and into the digestive tract and blood, some are through the epidermis, and some are through the stomata and trachea. It degrades the drug and loses its toxicity, but some drugs are activated to enhance the toxicity, and the drug that has not been degraded (or activated compound) exerts poisonous effect in a certain part due to different mechanism of action, such as acting on the nervous system or In the process of intracellular respiration and metabolism, most of the pesticides on the market today use chemical synthesis. These plant pesticides are highly toxic and remain in crops for a long time, causing irreversible damage to the environment and posing a huge threat to human health.
