1, leek, cabbage and cowpea belong to & lt; High risk food for pesticide residues;.

the results showed that leek was the only vegetable that had been on the list of pesticide residues in four years. Li Shidong pointed out that the lowest qualified rate of leek was mainly related to its root vulnerable to leek maggots. Besides leeks, cabbage is also a kind of & lt; High risk food for pesticide residues;, The main cause of pesticide residues is & quot; Heart filling & quot; It was caused by spraying. Cowpeas also need to use a large number of pesticides to control pests, and the spraying period is generally close to the picking period, which will lead to some mature cowpeas being sold on the market before the natural decomposition of pesticides, so the pesticide residue is also high. The detection rate of pesticide residues in

2, beans, green leaves and Solanaceous Vegetables was higher. Melons and edible fungi are more reassuring.

the laboratory of agricultural products monitoring center in Yuhang District of Hangzhou city has been testing 440000 vegetable samples for one year. The results show that different vegetable varieties have different qualified rates. From low to high, the qualified rate is beans (cowpea, Canary beans) < eggplant (eggplant) < green leaf vegetables (celery, oil wheat vegetables) < taro root vegetables (potato) < onion and garlic (chive) < melons (cucumber, balsam pear), edible fungi (Pleurotus ostreatus). In brackets are the vegetables whose pesticide residues exceed the standard. Among them, aquatic vegetables, wild vegetables and sprout vegetables are the most reassuring, and the qualified rate is 100%. It is worth noting that this rule is not completely applicable to all parts of the country because of the differences in vegetable producing areas.

3, from the month point of view, June and August vegetable qualified rate is the lowest, the highest in March.

in the survey, researchers from the agricultural product quality and safety supervision, inspection and testing center of the Ministry of agriculture found that the over standard rate of pesticide residues in vegetables increased first and then decreased over time. The exceeding standard rate of pesticide residues in vegetables was the lowest in March, the highest in June, the second highest in August, and decreased significantly again in November. This is almost similar to many other domestic research results. Li Shidong pointed out that the ups and downs of the curve have always been observed, and many variables have been mixed in, such as climate change and the serious occurrence of diseases and insect pests in summer.

4. Vegetables in supermarkets are not necessarily safer than those in farmers’ markets. From December 2007 to September 2008, a test result of organophosphorus pesticide residues in nearly 40000 vegetable samples in Changsha showed that the qualified rate of vegetables from 22 farmers’ markets was higher than the comprehensive data of 26 supermarkets. The research group speculated that the vegetables in supermarkets mainly come from designated vegetable production bases, which pay attention to the appearance quality of vegetables, and the application amount of pesticides may be higher than that of small-scale self-produced vegetables.

finally, it should be noted that although many vegetables have been detected with pesticide residues exceeding the standard, according to a number of relevant test data, the average qualified rate of pesticide residues of vegetables in China is more than 90%. For example, the qualified rate of 440000 vegetables mentioned above is 99% and 91%. After proper treatment, we can have a safe meal.
