The Consumer Survey column of CCTV recently exposed the phenomenon that some vegetable growers in Zengcheng and Conghua District of Guangzhou used banned pesticides on vegetables and other crops, putting the issue of high toxic pesticide supervision on the table again. In fact, there have been many incidents of using highly toxic pesticides to grow vegetables in Guangdong in recent years. Since 2010, at least 12 cases have been involved in 6 cities, including Zhongshan, Dongguan, Foshan, Zhuhai, Jiangmen and Guangzhou.

However, recently, media reporters visited several vegetable bases in the Pearl River Delta where the "toxic vegetable" incident had occurred, and no re-use of highly toxic pesticides was found. The problem of "toxic vegetables" has not recurred, partly because the crackdown on illegal use of drugs by vegetable farmers has been stricter everywhere. For example, in Sanshui, Foshan, Shaxi, Zhongshan and other places, vegetable farmers have been sentenced to 9 months for using highly toxic pesticides to grow vegetables.

Agricultural products cannot be separated from pesticides, just as food cannot be separated from various additives. However, everything is too much to say. The excessive use of pesticides in vegetable planting, even the use of restricted pesticides or banned highly toxic and highly toxic pesticides, is completely the opposite of the rational use of pesticides. From the experience of Foshan, the key to eliminate "toxic vegetables" is to crack down on the illegal use of highly toxic pesticides in accordance with the law.

The harm of highly toxic pesticides is obvious. The use of highly toxic and highly toxic pesticides in the planting of vegetables, melons and fruits can easily lead to excessive pesticide residues, harm human health and bring a strong sense of insecurity to consumers. Scientific research results have shown that the harm of pesticides to human body is mainly manifested in three forms: acute poisoning, chronic harm and carcinogenic, teratogenic, mutagenic and other "three causes" harm.

It remains in soil and water, causing serious pollution to the environment. The data is convincing: China's pesticide use is 2.5 times the world average. At present, about 1.75 million tons of various pesticides are used every year, of which 70% enter the soil, air and water, and only 30% directly affect the target organism.

In fact, highly toxic pesticides should not be used in vegetables, melons, fruits, tea and Chinese herbal medicine, which has been explicitly stipulated in China. Article 27 of the Regulations on the Administration of Pesticides, revised in 2001, clearly stipulates that "highly toxic and highly toxic pesticides shall not be used for the prevention and control of health pests, and shall not be used for vegetables, fruits, tea and traditional Chinese medicine."

Since 2011, the Ministry of Agriculture has required highly toxic pesticide business units to verify and standardize, purchase pesticides with real names, record the flow of information, and dynamically manage the flow of targeted pesticides, so that 100% of the information of highly toxic pesticides can be queried, 100% of the flow can be tracked, and 100% of the quality can be guaranteed. The "historically stricter" food safety law, which was officially implemented on October 1 this year, also clearly stipulates that "it is prohibited to use highly toxic and highly toxic pesticides on vegetables, fruits, tea, Chinese herbal medicine and other crops specified by the state."

However, up to now, relevant regulations and requirements still cannot stop the pace of spraying high toxic pesticides on vegetables and fruits. High toxic pesticides are sold and abused at will, and even the pesticides produced and used by the state are sold and used at will.

The reasons are: on the one hand, the sales of highly toxic and highly toxic pesticides are too casual and not managed according to the specifications; On the other hand, it is difficult to popularize biopesticides. Although the level of research and development of biopesticides in China is comparable to that in the world, the high cost has become a major problem hindering the promotion; Basically, China's agriculture is still a smallholder economy dominated by one household, leading to the lack of effective restraint and supervision in the use of highly toxic and highly toxic pesticides, and the imperfect regulatory system. According to national regulations, agricultural products such as vegetables, melons and fruits must be tested for pesticide residues before they go on the market. However, due to the lack of technology and funds, the detection of agricultural products in many places is virtually non-existent, resulting in farmers' concern about the use of highly toxic pesticides The understanding of heavy toxic pesticides is not deep enough.

It is imperative to ban highly toxic and highly toxic pesticides, which is not only the need of domestic people's health, but also the need to comply with the international trend. Many international conventions explicitly require strict control over the production and use of highly toxic and highly toxic pesticides. It can be said that today's agricultural product market is also a global market, always facing the competition of the international market. Moreover, many foreign high-quality agricultural products have come to us now. If we lag behind foreign products in pesticide residues, we may lose even the "competition at home".

Good law is the premise of good governance. After the legislation stipulates that highly toxic and highly toxic pesticides are prohibited for vegetables, melons and fruits, how to really manage the use of highly toxic and highly toxic pesticides must also rely on supervision. First, strictly manage pesticides from the source. On the one hand, strictly control and prohibit the production of highly toxic and highly toxic pesticides, and severely punish the illegal production and operation of using highly toxic and highly toxic pesticides according to law; On the other hand, we will implement fixed-point operation of highly toxic and restricted pesticides, counter sales, adult real-name purchase, and prohibit online sales and purchase of highly toxic pesticides.

In addition, it is necessary to improve the access threshold of agricultural products in the farmers' market, increase the pesticide residue detection of vegetables, melons and fruits, especially the pesticide residue detection of agricultural products in the small farmers' market, and ensure that the vegetables, melons and fruits flowing into the public table are qualified; Furthermore, we should straighten out the management system, clarify the division of labor, form a joint force, and strictly control the use of highly toxic pesticides.

Of course, in addition to strict law enforcement and severe punishment for those who use excessive pesticides in violation of regulations, the government must also introduce relevant policies to support more new ecological and biological pesticides to speed up the pace of substitution, and at the same time provide subsidies to farmers to make them affordable and willing to use low-toxicity and low-residue pesticides. Such efforts should help to truly safeguard the safety of the public.
