as the variety and origin of fruits and vegetables on our table become more and more abundant, the problem of pesticide residues will never stop“ Which fruits and vegetables may contain more pesticides and which fruits and vegetables contain less pesticides“ How can we minimize the amount of pesticides we eat? ” It has become the topic that many people talk about most often. Some people take this opportunity to sell fruit and vegetable detoxification machine and pesticide degradation agent.
let’s find out which vegetables and fruits are less pesticide.
1. Cowpea, leek pesticide more
cucumber, tomato fungicide more. Cowpeas prefer to grow insects, and a large amount of pesticides will be used when planting. Like leek, onion root is easy to grow leek maggots and other pests, often irrigated with thick pesticides, some of which are more toxic and easy to remain. Cucumber and tomato growth environment humidity, easy to get sick, the general dosage is relatively large, especially the use of fungicides. However, compared with pesticides, fungicides are less harmful to human body. In fact, Chinese cabbage is a reassuring dish
. Chinese cabbage is generally planted in autumn, and only some insecticides to control aphids and Plutella xylostella are used in seedling stage. It is far away from the market time, that is, people eat vegetables for a long time, with less pesticide residues. It’s the same with cabbage and lettuce. There are few pesticides for vegetables and fruits in the greenhouse.
physical methods such as anti-virus net can be used to control pests in the greenhouse, so the pesticides are less. Compared with greenhouse vegetables, open vegetables look more natural, but it is more difficult to control diseases and pests, and more pesticides will be used than greenhouse vegetables.
4. It is safest to eat leafy vegetables in winter
. Leafy vegetables in winter and spring and autumn are very safe, because there are few insects and almost no pesticides. However, we should be careful when eating vegetables in summer, because at this time, not only are there many insects, but almost all the vegetables in the greenhouse have been collected. Most of the vegetables sold in the vegetable market are open vegetables, with more pesticide residues.
5. You can eat more fragrant dishes.
Artemisia stem, chrysanthemum, coriander, etc. have a strong pungent flavor and are natural insect repellents. Fewer insects, these vegetables naturally do not need pesticides. Among the wild vegetables, only Pteridium aquilinum is the most natural. There are no pesticide residues in the wild vegetables. However, only Pteridium aquilinum is the natural wild vegetables that grow in the mountains. Amaranth and shepherd’s purse are almost all artificially planted. Amaranth used less pesticides, shepherd’s purse was easy to produce aphids and used more pesticides.
7. Don’t be superstitious about fruits and vegetables with wormholes.
there are only wormholes on fruits and vegetables, but no insects. It means that insects are killed by pesticides. Moreover, the pesticide application time of the vegetables with wormhole is closer to the harvest, the pesticide decomposition is less, and the residue is high.
8. There are less pesticides in fruits with short growth cycle. For example, cherry has only more than two months from germination to ripening, so it is impossible to use too many pesticides.
9. There are few pesticides for fruits in famous producing areas. The climate in Xinjiang is dry, and there are few pests on fruits and vegetables, and there are few pesticides. There are also apples and pears in Shaanxi and Shanxi, which have less pesticide residues than those in the south.
