In modern planting, pesticides have been widely used. However, due to the existence of some illegal pesticides and irregular operations, the level of pesticide residues in vegetables has become a common concern of the general public. Therefore, we have conducted monitoring of the level of pesticide residues in the whole year of listed vegetables in this Municipality. Experimental methods: Data statistics Select the main edible vegetable species, including cabbage, root vegetables, green leafy vegetables, onion and garlic, eggplant, melons, beans, yam, aquatic vegetables, edible fungi, sprouts There are 14 categories and a total of 86 varieties. Samples of 446,577 batches were collected and tested and lasted one year. Experimental results: The monitoring data of the pesticide residue showed that the overall quality of the listed vegetables in the city was in good condition. The annual average pass rate was 99.91%. According to the statistics of the test data, the main over-species vegetables are as follows: Cabbage: Chinese cabbage, Chinese cabbage, green vegetables; Green leafy vegetables: celery, leaf lettuce, and oiled wheat; Solanum: pepper, eggplant; Beans: kidney beans, beans; Root vegetables: radish; Melons: cucumber, bitter gourd; Onions and garlic: chives; Edible fungus: Pleurotus ostreatus; yam potato: potato. From the variety point of view, different vegetable varieties have different passing rates. The qualified rate of beans was the lowest, followed by leafy vegetables and solanaceous fruit. The pass rate from low to high was in order of legumes< Solanum <yield <green leafy vegetables> sweet potato rooted vegetables <onion garlic <melons, edible fungus. Among them, aquatic vegetables, perennial vegetables, wild vegetables, sprouts, and others (including corn, peanuts, etc.) are the most reassuring, with a pass rate of 100.00%. Laboratory suggestion: According to the reports of pesticide residues in other regions of the country, beans such as cowpea, jack bean, and green beans have high levels of general pesticide residues and the lowest pass rate. Therefore, it is best to eat beans after hot. Leafy vegetables are also relatively high in pesticide residues, and leaf vegetables are more susceptible to pests and diseases. Moreover, pesticides are directly sprayed on the surface of lettuce leaves. The surface area is large and pesticides absorb quickly. Coupled with the short growing period of leafy vegetables, it is difficult to achieve a safe interval between the use of drugs and the market, making pesticides less likely to volatilize to market, and eventually lead to more attached pesticides. The unqualified rate of cabbages was generally higher than that of green leafy vegetables. The most reassuring items are melons, sprouts, and corn and peanuts. Sprouts have a very short growth period and do not require the use of pesticides. Corn and peanuts are not directly exposed to pesticides, and of course they are safer.
