How to eat green leafy vegetables if you are afraid of pesticides?

Amaranth - Do not buy vegetables with a large amount of fertilizer. Due to the excessive application of chemical fertilizers, especially nitrogen fertilizers (such as urea, ammonium sulfate, etc.), nitrate pollution of vegetables will be serious. After testing the marketed vegetables, it was found that the nitrate content was ranked from strong to weak

Root vegetables, potatoes, green leafy vegetables, cabbage, onions and garlic, beans, melons, eggplants, edible fungi, nitrate content can vary by up to 10 times. The law is that the pollution degree of vegetable roots, stems, and leaves (i.e., vegetative bodies) is much higher than that of flowers, fruits, and seeds (i.e., reproductive bodies), which may be a common protective response in the biological world. Eat as many melons, fruits, beans and mushrooms as possible, such as cucumbers, tomatoes, edamame, shiitake mushrooms, etc.

The second is not to buy multi-insect vegetables. Among the many vegetables, some vegetables are easy to be favored by pests and can be called multi-insect vegetables; Some vegetable insects do not like to eat much, and they can be called less insect vegetables. Vegetables with fewer insects include chrysanthemum, lettuce, celery, carrots, onions, garlic, leeks, green onions, coriander, etc.

Due to the large number of insect pests, multi-insect vegetables have to be sprayed frequently, which is bound to form pesticide residues; In the case of insect-less vegetables, on the other hand, in order to avoid excessive exposure to pesticides, you should usually choose as many insect-less vegetables as possible. The third is not to buy vegetables with abnormal shapes and colors. Vegetables with normal shape and color are generally cultivated by conventional methods.

Abnormal vegetables may have been treated with hormones, such as leeks, when their leaves are particularly wide and fat, twice as wide as the average broad-leaved leek, they may have been treated with hormones during the cultivation process. Leeks that have not been subjected to hormones have narrower leaves and have a strong flavor when eaten. Some vegetables are not normal in color, but also pay attention to, such as the leaves lose their usual green and are dark green, edamame green is abnormal, etc., they may be sprayed or soaked in methamidophos pesticides before harvesting, and should not be purchased.

Nowadays, most vegetables have pesticide residues, and the best way is to soak them in salt water for 15 minutes. Satisfied.

Pesticides are known to be toxic and harmful to the body. Therefore, we must be cautious to use those with low toxicity and short residual effect, which is extremely important for our own safety! Green worm fungus, borericidal bacillus, caterpillar pine, golden thuringiensis, Beauveria bassiana.

Pyrethrins: pyrethrin, deltamethrin, cypermethrin.

<> suggest that vegetable growers do not use pesticides during the planting period, if it is a large-scale planting of vegetables, it must be used, and it is also recommended that we choose a non-toxic, harmless, and no chemical ingredient pesticides for weeds and insects. The agent acts on the mitochondria of cells in insects, and acts through multifunctional oxidases in insects, mainly inhibiting the conversion of adenosine diphosphate to adenosine triphosphate.

The household does not raise pigs, and the three birds rely on the money from the part-time job to buy it as a plate. In addition, spraying agricultural fertilizer, any crop in modern times, without spraying pesticides, there is no harvest. In the past, it was only a seasonal crop, and there were no pests.

Today's varieties have a lot of insect pests. But I know very well that people are not as good as heaven, natural disasters are inevitable, pests and diseases occur from time to time, and weeds can be seen everywhere. If the manufacturer does not produce chemical fertilizers and pesticides, farmers cannot use chemical fertilizers and pesticides.

For example, if there is no market for 666 powder, farmers will not use this insecticide. If chemical fertilizers and pesticides are harmful to humans and animals, then production and use should be limited.

Do not use pesticides, not because of anything else, or because of small households, the planting area is limited, mainly can be used as waste, save costs, and the second is to eat by yourself, not for sale, do not care about the quality of the product. When all the farmers in China have left the land, the crops, the fruits and vegetables, they will no longer use pesticides and fertilizers. However, professional and technical personnel in the land of medicine fish in China still use pesticides.

It can be sung in a high tone, but agricultural production is something that needs to be paid attention to. Singing a high note with a hungry stomach will never sing well with a high note.

If you don't know how to spray pesticides, you can consult your grandparents, after all, grandparents have farmed.

You can ask your neighbors to help you, or you can ask your relatives or your parents to help you, but you must learn it yourself.

Ask for advice from others, ask from experienced people, and you can learn.

1. The pesticide components of salt on vegetables and fruits are mostly fat-soluble substances, if you use brine to clean, the solubility of brine to fat-soluble compounds is not good, and most of the diluted brine is treated by soaking in hand cavity sails, and the effect is not better than rinsing with water.

2 The chemical name of baking soda is sodium bicarbonate, which is weakly alkaline and is often used in food to neutralize acidity. However, there are many acidic pesticides, and in alkaline cyclohail environments, the degradation rate will become faster. For example, the insecticide marathon, which is commonly used in cruciferous vegetables or leafy vegetables, has a semi-degradation cycle of six days in the pH7 environment and only half a day in the PH9 diet.

However, washing vegetables is usually completed in ten minutes, so the effect of using baking soda for a short time may not be better than rinsing with water.

3. Vinegar is acidic, so cleaning vegetables and fruits with insecticides with vinegar will prolong the degradation time, and the effect of removing pesticides is counterproductive, and the taste of vinegar will remain on the fruits and vegetables, and if raw food is not cooked, it will affect the flavor of food.

4 It can be seen that the effect of rinsing with water is the best. In addition to cleaning, residual pesticides can be decomposed, dispersed with steam, or dissolved into oil and water by means of heating and cooking.

How do you remove pesticides from vegetables?

In addition to the peeling method, there are several simple ways to remove pesticide residues on vegetables and fruits:

Soaking and washing method: The pesticides that pollute vegetables are mainly organophosphorus insecticides. Organophosphate insecticides are insoluble in water, and this method can only partially remove contaminated pesticides. However, washing is the basic method to remove other dirt and remove residual pesticides from vegetables and fruits. It is mainly used for leafy vegetables, such as spinach, enoki, leek flowers, lettuce, bok choy, etc.

Generally, the surface dirt is rinsed off with water first, and then soaked in water for no less than 10 minutes. Fruit and vegetable cleaners can promote the dissolution of pesticides, so a small amount of fruit and vegetable cleaners can be added when soaking. After soaking, rinse with water 2-3 times.

Alkaline water immersion method: organophosphorus insecticides decompose quickly in an alkaline environment, so this method is an effective measure to remove pesticide pollution, which can be used for all kinds of vegetables and fruits. The method is to rinse the surface dirt first, soak it in alkaline water (generally add 5-10 grams of alkaline surface to 500ml of water) for 5-15 minutes, and then rinse it with water 3-5 times.

Storage: Pesticides can be slowly decomposed into substances that are not harmful to humans over time in the environment. Therefore, fruits and vegetables that are easy to preserve can be stored for a certain period of time to reduce the amount of pesticide residues.

This method is suitable for non-perishable species such as apples, kiwifruits, and winter melons. Generally, it is stored for more than 15 days. Be careful not to consume freshly picked unpeeled fruit immediately.

Use more running water for cleaning.

Real organic food has been very popular in the market, and there are not many real organic green vegetables in the market now. For example, vegetables with organic certificates are not necessarily organic vegetables, and vegetables without organic certificates must not be organic vegetables, even if they are planted cleanly, they cannot be called organic vegetables. So, what are real organic greens?

Are real organic greens pesticides? The following country songs will be with you**.

1. Are vegetables with wormholes organic greens? Can you eat vegetables that have been bitten by insects?

Vegetables with wormholes are not necessarily organic greens. Because those with wormholes are not necessarily those that have not been sprayed with pesticides, and some are pesticides that have been sprayed after the wormholes appear; Pesticides are not necessarily not environmentally friendly, and most pesticides are pesticides with relatively low residues, as long as the safety period has passed, the problem is not big.

It is best not to eat vegetables that have been bitten by insects. Because insects will produce harmful substances in the process of biting vegetables, such as aflatoxins (strong carcinogens), which will induce liver cancer, which is more harmful; Once the vegetables are eaten out of the hole, vegetable farmers will definitely use higher concentrations of pesticides to prevent and control in order to "rescue" the vegetables. It can be said that vegetables with insect eyes are not only unsafe, but may be more dangerous.

2. Real organic green vegetables are not allowed to use chemically synthesized pesticides, but biological, physical and mineral pesticides or methods without any pollution can be used to achieve the purpose of insect treatment and disease prevention. Such as insect nets and insect control, yellow or blue boards to kill insects, etc.

3. Are there many organic green vegetables on the market at present?

It is difficult to market vegetables that are completely free of pesticides.

When I grow vegetables, especially Chinese cabbage, pai cai and Shanghai greens, etc., don't grow too tall without pesticides, and the dense little insects will crawl all over the leaves, and they will all be eaten up in a few days. In this case, how can there be vegetables to market? Some people say that the current organic certification is also very messy, whether it is really organic depends on the conscience of the enterprise, so when you see that kind of high-end vegetables, you will take a detour, which is purely a quick response to people who are stupid and have a lot of money.

The bar for growing truly organic greens is high. In the planting of organic green vegetables, it is necessary to ensure that there is a certain isolation zone between the organic land and the conventional land, including the water quality and agricultural tools of the watering land to avoid pollution, and to achieve that the planting land of the base does not produce for 5 years, and there is no income and net input within 5 years. Every year, the crops should be rotated, and the crops will grow into the ground, and the soil organic matter content will be continuously improved, and during this period, a large amount of organic fertilizer should be applied, and chemical fertilizers, pesticides, insecticides, etc. must not be used.

Think about it, just this requirement, how many people can do it?

Truly organic greens are something that can only be achieved by being tested with a conscience. In the production of organic green vegetables, it is necessary to avoid the transgenic and transgenic derivatives of vegetable seeds, and to use organic seeds, and to use organic fertilizers in the planting process, and to absolutely prohibit the use of pesticides in the planting process. If the real epidemic or insect plague comes, when facing the harvest of the year or season, whether to use medicine or not, this is definitely a test of the conscience of the operator, at this time the capital is profit-seeking, can you pass the test?

It is very difficult for real organic green vegetables to be free of pesticides at all, because vegetables such as cabbage and Shanghai green are difficult to prevent small insects if they are not pesticides at all.

I will use some pesticides, because even organic green vegetables can sometimes get insects and get sick, so I must use pesticides.

These vegetables are also pesticides. But most of these pesticides are used to prevent insect infestations. There won't be much damage to the human body.

1. Organic mercury preparations. Such as Xilisheng, Sailisan, Futulong, mercury, etc., this kind of pesticides are highly toxic to humans and animals, when used, such as pesticide contact with **, especially with the tetanus contact or spraying inhaled from the nostrils, easy to accumulate in the human body is not easy to discharge, resulting in cumulative poisoning.

2. Organophosphorus preparations. Such as, triphosphorus, phosphorus, flying phosphorus, etc., this kind of pesticide is more toxic to humans and animals, it can directly enter the body through the mouth, so that people are poisoned, and can also enter the human body through ** penetration and respiratory tract and other ways and poison.

3. Organochlorine preparations. Such as six six.

6. DDT is less toxic than these two pesticides, but because of its stable nature, it is not easy to decompose in organisms and soil.
