At present, farmers are increasingly growing Chinese herbal medicines. The correct selection of pesticides for pest control is a key measure to improve the quality of medicinal materials. According to national regulations, the following pesticides are prohibited from use on Chinese herbal medicines:
1. Virulent pesticides. Usually the species is 3911, methyl 1605, 1059, monocrotophos, methamidophos, carbofuran, sodium cyanide, potassium cyanide and so on. When they are used in Chinese herbal medicines, they are easily absorbed and permeated into plant tissues such as roots, leaves, and pericarp, and they are not easily scattered or disappeared by wind and rain. The harvest time of Chinese herbal medicines is approaching, and some of the pesticide components have not been degraded. After processing and use, acute poisoning is likely to occur. Coupled with the slightest attention to the use of such pesticides, human and animal poisoning accidents are prone to occur. Therefore, the use of Chinese herbal medicines is prohibited.
2. High residue pesticides. Such as 666, DDT, chlordane and so on. Although they are not acutely toxic to humans and animals, they have a long residual period and are highly accumulative. They are less likely to be decomposed in Chinese herbal medicines and cause long-term accumulation of chronic poisoning after entering the human body. Therefore, they are also prohibited from being used in Chinese herbal medicines.
3. Organic mercury pesticides. Such as Saili San, Xilisheng, Fuminlong, etc., this kind of pesticide has strong bactericidal power, and it has a good effect in preventing and treating the damage of Chinese medicinal materials, but it will be decomposed into inorganic mercury and can remain for many years without disappearing. After the human body absorbs it, The damage to the nervous system and the heart is very large. Therefore, the state has already forbidden production and use.
4. Kill insects. Experimental studies have demonstrated that a small insecticidal dose can induce a variety of cancers in mice. Therefore, the state has stipulated that it is not allowed to use insecticides on Chinese medicinal materials, fruit trees and vegetables, and tea.
