Problems and Countermeasures of Pesticide residues in vegetables

In the process of vegetable production, the use of chemical pesticides to control diseases and insect pests is a very common means, the control effect is very significant, but some pesticides will remain in vegetables, which will cause certain harm to people's health. Out-of-season vegetables and greenhouse vegetables are developing rapidly. The type and quantity of chemical pesticides are gradually increasing, and the control effect is getting better and better, but chemical pesticides are toxic after all. In order to improve the yield and quality of vegetables, chemical pesticides are widely used by vegetable farmers in the process of vegetable production. In order to ensure the safety of consumers eating vegetables, it is very important to study the problem of pesticide residues in vegetables and put forward corresponding countermeasures, which can not only reduce the amount of pesticide residues in vegetables, but also ensure people's health.

I. causes of pesticide residues in vegetables

In the process of vegetable production, in order to cope with the impact of environmental pollution, market demand, diseases and insect pests and other factors, vegetable farmers will generally increase the variety or use of pesticides, which will lead to the increase of pesticide residues in vegetables. some pesticide residues may not be removed. From the perspective of consumer health, the emergence of this situation is very disadvantageous, vegetable farmers will increase the use of pesticides or the number of times. Vegetable varieties prone to diseases and insect pests or high demand tend to have more pesticide residues. At present, some vegetable farmers often overuse pesticides in order to improve the yield and sales of vegetables. This phenomenon directly increases pesticide residues in vegetables.

Harm of excessive use of pesticides in vegetable production

II. Harm of pesticide residues in vegetable production

Nowadays, with the development of the times and the continuous progress of science and technology, there are more and more kinds of pesticides. Some vegetable farmers use highly toxic or highly toxic pesticides banned by the state in order to pursue insecticidal effects and save costs. Although these pesticides have good insecticidal effect, low dosage and low cost, people's intake of essential nutrients will be limited, and over time, they will cause serious health problems. The destruction of ecological pollution will make the land in vegetable growing areas also eroded by pesticides, resulting in the problem of environmental pollution.

III. Countermeasures to reduce excessive pesticide residues in vegetables

Pesticide residues in vegetables will bring great harm to consumers' health and society, so strictly implement pesticide use standards, vigorously develop green and pollution-free vegetable industry, strictly test pesticide residues in listed vegetables, and stop those who exceed the standard of pesticide residues from entering the market. First, the promotion and certification of pollution-free agricultural products, green food, organic agricultural products and agricultural products. Through the certification of "three products and one standard", vegetable planting enterprises and parks are restricted by the guidelines for the use of pesticides and can only spray low-toxic and low-residue pesticides allowed in the guidelines for the use of pesticides. Effective measures to reduce excessive pesticide residues in vegetables. The second is to strengthen vegetable technical training, quality and safety knowledge training. In the final analysis, vegetable production is completed by vegetable farmers. therefore, strengthening vegetable technical training for vegetable farmers is the key to solve the problem of pesticide residues. As long as vegetable farmers master scientific vegetable planting techniques and pest control norms. The third is to strengthen the detection of pesticide residues. Before the vegetables are on the market, the pesticide residues in vegetables should be detected to ensure that the pesticide residues in vegetables meet the corresponding listing standards. Should be equipped with agricultural residue detection equipment, batch self-test. Ensure the quality and safety of vegetables on the market. In the course of testing, once pesticide residues are found to exceed the standard or substandard vegetables, they should be dealt with immediately. If pesticide residues cannot be removed, they should be destroyed. If the pesticide residues are easy to remove, they can be treated accordingly before entering the market. Nowadays, the problem of pesticide residues in vegetables has become the focus of attention from all walks of life, which is related to the health of the people. Therefore, it is very important to study the problem of pesticide residues in vegetables and deal with the vegetables with excessive pesticide residues. For pesticide residues in vegetables, we should start from the source.
