In the vegetable production process, the use of chemical pesticides to prevent and treat pests and diseases is a very common method, and the control effect is very significant, but some pesticides will remain in the vegetables and cause some harm to people's bodies. Anti-season vegetables and greenhouse vegetables are developing rapidly. The types and quantities of chemical pesticides have also gradually increased. The prevention and control effects are also getting better and better, but chemical pesticides are poisonous after all. In order to increase the yield and quality of vegetables, vegetable farmers are widely used in the production of vegetables. In order to protect the safety of consumers' consumption of vegetables, it is important to study the problem of pesticide residues in vegetables and propose corresponding countermeasures. This will not only reduce pesticide residues in vegetables, but also ensure people's health.
I. Causes of Pesticide Residues in Vegetables
In the vegetable production process, in order to cope with the environmental pollution, market demand, pests and other factors, vegetable farmers will generally increase the number of pesticides or the number of uses, which will lead to increased pesticide residues in vegetables, some pesticide residues may not be removed . From the perspective of consumer health, this situation is very unfavorable, and farmers will increase the amount of pesticides used or the number of uses. Vegetables that are prone to diseases and pests or are in great demand tend to leave more pesticides. At present, some vegetable farmers often use excessive amounts of pesticides to increase the output and sales of vegetables. This phenomenon directly increases pesticides in vegetables. Residues.
Overuse of pesticides in vegetable production
Second, the existence of pesticide residues in vegetable production
Nowadays, with the development of the times and the continuous advancement of science and technology, more and more types of pesticides have been used. Some vegetable farmers have used banned highly toxic or highly toxic pesticides in order to pursue insecticidal effects and save costs. Although these insecticides have good insecticidal effect, low dosage, and low cost, they will make people's intake of essential nutrients limited, and over time, they will cause serious health problems. Destruction of ecological pollution will cause the land in vegetable growing areas to also be eroded by pesticides, causing environmental pollution.
Third, reduce the excessive pesticide pesticide residues countermeasures
Vegetable pesticide residues will cause great harm to consumers' health and society. Therefore, strict implementation of standards for pesticide use, vigorous development of green, pollution-free vegetable industry, strict inspection of pesticide residues in listed vegetables, and prevention of excessive pesticide residues in the market. The first is the promotion of pollution-free agricultural products, green foods, organic agricultural products and agricultural products. With the certification of “three products and one standardâ€, vegetable growing companies and parks are subject to the “Pesticide Use Guidelines†in the process of using pesticides and can only spray pesticides. The use of low-toxic, low-residue pesticides allowed in the Guidelines. Effective measures to reduce excessive pesticide residues in vegetables. The second is to strengthen the training of quality and safety knowledge in vegetable technology training. In the final analysis, the production of vegetables is done by vegetable farmers. Therefore, strengthening the vegetable technical training for vegetable farmers is the key to solving the problem of pesticide residues. As long as vegetable farmers have mastered the scientific vegetable cultivation techniques and pest control norms. The third is to increase the detection of pesticide residues. Before vegetables are listed on the market, pesticide residues in vegetables should be tested to ensure that the pesticide residues in the vegetables meet the corresponding listing standards. Should be equipped with pesticide testing equipment, batch self-test. Ensure the quality and safety of listed vegetables. During the testing process, if excessive pesticide residues or unqualified vegetables are found, they should be disposed of immediately. If residual pesticides cannot be removed, they should be destroyed. If residual pesticides are relatively easy to remove, they can be recycled into the market after appropriate treatment. Today, the issue of pesticide residues in vegetables has become the focus of attention of all walks of life and concerns the health of the people. Therefore, it is very important to study the problem of pesticide residue in vegetables, and to treat vegetables that have excessive pesticide residues. For pesticide residues in vegetables, start with the source.
