What kind of medicinal materials are planted by farmers, and the planting area is subject to market regulation. In the process of prevention and control of pests and diseases, it is entirely up to the farmers themselves to decide which pesticide and which method to apply.
In the past few years, the Institute of Medicinal Plants of the Chinese Academy of Medical Sciences undertook the investigation of the status quo of the production of Chinese herbal medicines by the State Administration of Traditional Chinese Medicine. The research focused on the seed, seedlings and herbal medicines of Chinese herbal medicines, and the status of plant protection is worrying.
One of the concerns: At present, there are no regulations or regulations for the use of pesticides in the production of Chinese herbal medicines. In 1982, the Ministry of Agriculture, Animal Husbandry and Fisheries and the Ministry of Health issued the Regulations on the Safe Use of Pesticides, which stipulated that high-toxic pesticides should not be used in crops such as vegetables, fruit trees and Chinese herbal medicines. None of the Chinese herbal medicines were included in the items of the chemical pesticides, the toxic classification, the allowable final residue limit, and the last application interval from the production of Grade A green foods. In the "Pesticide Residue Test Guidelines" formulated by the Ministry of Agriculture's Pesticide Testing, 17 pesticides were tested for 91 pesticides, all of which were food, fruit and vegetables. For Chinese herbal medicines, only "can refer to the above crops as appropriate" And set." It is understood that foreign countries have promulgated standards for pesticide residues in botanicals, such as red ginseng and senna in the Japanese Pharmacopoeia. The lack of pesticide use regulations in the production of medicinal materials in China has resulted in an objective reality that production and supervision have no legal basis. The use of pesticides is in a state of laissez-faire.
Worry 2: The peasant growers lack basic basic plant protection knowledge, and the abuse of pesticides is very serious. Farmers fight drugs as soon as they see the insects. They are effective in selecting the pesticides. Second, they are cheap, and little consideration is given to the effects of pesticide toxicity on the quality of the herbs. This year, we conducted a survey in the pesticide sales department of a medicinal material production area, and found that farmers mainly purchase high-toxic pesticides such as omethoate, monocrotophos, parathion, and dicofol for controlling pests on medicinal materials, while low-toxic pesticides. Very few people care about it. Some Chinese medicinal materials suffer from more than a dozen pests and diseases during the growth process. In order to ensure a good harvest, farmers use drugs almost every week, and often use several high-toxic pesticides, especially in the severe period of pests, the concentration of pesticides is doubled, and even insects and insects are used to fight drugs. During the growth period, the number of fights is as high as 20 or even 30 times. The drug farmer uses a high concentration, sprays the carbofuran granules, etc. In this way, the natural enemies of a large number of pests and diseases are killed, the resistance of pests and diseases is increased, the cost of prevention and control is more and more difficult, and the environment such as soil and water in the medicinal materials production area is polluted. The production of medicinal materials brings about continuous harm. It forms a vicious circle that is difficult to reverse, making the quality of the medicines worse and worse.
The third worry: the pesticide market is chaotic, the ingredients are unknown and there are many fake and inferior pesticides. In China's pesticide market, there are more than 200 kinds of pesticides. Except for imported pesticides and a few domestically produced pesticides, which indicate the trade name, common name and chemical structure, most domestic pesticides are mixed pesticides, only Chinese names are listed, but active ingredients or groups. Unclear. What's more, some criminals create and sell fake pesticides, delay the prevention and control of pests and diseases, increase the difficulty of prevention and control, and cause undue economic losses to farmers.
Medicinal herbs should be curative, but herbs containing pesticide residues are likely to pose a greater threat to the disease. Failure to pay attention to and not solve this problem will affect the development of the Chinese medicine industry in the long run. The solution to this problem lies in the establishment of a large-scale, standardized Chinese herbal medicine production base, and vigorously carry out research on standardized production techniques of Chinese herbal medicines. Large-scale and standardized production is the prerequisite and fundamental guarantee for the stable and controllable quality of Chinese medicinal materials. It is completely different from the management and operation of Chinese medicinal materials scattered by farmers. It has great controllability and plant protection work is also easy to develop. . It is reported that the "Chinese Medicine Production Quality Management Regulations (GAP)" currently being developed in China will control the use of pesticides in the cultivation of medicinal materials. I hope that the introduction of this "Code" will lead to the abuse of pesticides in the production of Chinese medicinal materials. Changed.
