How long does it take for vegetables that have been sprayed with pesticides to eat? Is there a stand

Both of these are organophosphorus insecticides, highly toxic and highly toxic but easy to degrade under light conditions, generally 7-10 days before the harvest of vegetables are not allowed to play pesticides, this is to give pesticides a natural degradation time.

If you plant it yourself, I think you can fully abide by this principle, absolutely do not spray pesticides 7-10 days before harvest, then there are very few pesticide residues, if you buy it, pay attention to soak it with a small amount of edible alkaline solution, organophosphorus pesticides will be hydrolyzed in alkaline fields, reducing toxicity.

It depends on whether it rains during the period between the spraying of pesticides and the harvest, and if it rains, it will be shallow.

Pemethoate and other pesticides because they will remain in the form of crystals on the surface of vegetables, especially green leafy vegetables, so there is no expiration date, the safest way is to wash several times with salt water, note that it should be soaked in water before washing with salt water.

I am an agricultural university majoring in animals, and my classmates are ...... in the botanical class

Nowadays, there are basically no natural vegetables on the marketHowever, after the vegetables are sprayed, if the toxicity is relatively low, you can eat it in about 7 to 10 days, if the toxicity is medium, you have to wait for 15 days before you can eat, if you are using a high concentration of drugs, it will take a long time to eat, so how to distinguish which residual pesticides are more toxic and which are lower? <>

Introduction of vegetable species with relatively low pesticide residue toxicity: There are many kinds of vegetables in summer, if you like to eat pumpkin, bitter gourd, loofah, winter melon, relatively speaking, there are fewer pests and diseases, and there will be fewer pesticides. Like coriander, artemisia stalk, chrysanthemum and other vegetables with a strong taste, the taste itself is relatively large, not easy to be damaged by pests, and the medicine is lower than other vegetables.

Pesticide residue toxicity is introduced to many vegetable species: Personally, I think that cucumbers are more pesticides, and once I bought cucumbers and put them at home for many days without wilting. After searching on the Internet, I learned that cucumbers are frequently used with pesticides throughout the growing period.

The second is leeks, leeks will grow on the roots, so pesticides will also add a lot of pesticides to kill insects, so that there will be more residual pesticides.

Therefore, we must wash the vegetables carefully when washing them. Cleaning bitter gourd and loofah can be soaked in alkali and water for a period of time before washingIf you want to clean vegetables such as cabbage, Chinese cabbage or spinach, start with salt water orRice waterSoak for ten to ten minutes, or useSodaSoak in water for about 30 to 60 minutes, and then rinse with running water at the end。And the last way is to mix it with alkali and rice water, which together have a significant effect on organophosphate pesticides.

If you are still not at ease, you can blanch the water in advance as much as possible, and then go to cook, and the cooking time should be slightly longer, so that the food will be more assured when it comes to eating in your mouth.
