Can you eat vegetables that have been sprayed with boron sources, and can you eat vegetables that ha

You can eat it.

Many plants need to be reasonably pressed with boron fertilizer in the process of growth, so is boron fertilizer toxic to the body? The details are as follows:

Is boron fertilizer harmful to the human body: The appropriate use of boron fertilizer in the flowering period of plants can prevent flower and fruit dropping, and can also play a role in improving plant yield and quality. There are two kinds of boron fertilizers on the market, borax and boric acid, and it needs to be admitted that borax does have a certain toxicity.

But you don't have to worry too much, because under the condition of reasonable use of boron fertilizer, it will not cause any harm to the human body. When you use boron fertilizer, if you are afraid that it will volatilize and affect people's health, you can wear gloves to do a good job of protection, and do not touch it directly with your hands. Moreover, if the boron-watered plants are eaten, they should be washed twice before eating, and there will be no serious pesticide residue problems.

*I can eat it**. Boron source reservoir is a boron fertilizer that can be sprayed on vegetables to improve yield and quality. However, it is necessary to pay attention to the use method and safety, such as not touching it directly with your hands, and you need to use it reasonably to avoid waste.

At the same time, if you are worried about the impact of boron volatilization on your health, you can wear gloves to do a good job of protection. In addition, the plants watered by the boron source reservoir need to be washed twice before eating to avoid the problem of pesticide residues.

Herbicides contain carcinogenic substances, and vegetables absorb this poison. Not only are vegetables not cleaned to be harmful to our health, but they can also cause symptoms of poisoning if eaten wrong, so we must pay special attention to be careful.

It can be eaten, but it needs to be washed carefully, it is best to soak the vegetables in clean water for a period of time, and then rinse them repeatedly several times before eating them after there is no odor on the leaves.

Herbicide refers to a type of substance that can completely or selectively kill weeds, also known as herbicides, to eliminate or inhibit plant growth. Among them, sodium chlorate, borax, arsenate and trichloroacetic acid have a dead effect on any kind of plants, and their effects are affected by three factors: herbicides, plants and environmental conditions. According to the function, it is divided into incidal and selective herbicides, and most of the selective herbicides, especially nitrophenol, chlorophenol, and carbamate derivatives, are effective.

The development of herbicides in the world has gradually stabilized, mainly developing varieties with high efficiency, low toxicity, broad spectrum and low dosage, and disposable treatment agents with little environmental pollution have gradually become the mainstream.

1. Water spraying: When it is clear that the spraying dose of herbicides is too large, it should be sprayed with water in time to remove foliar residues, reduce the concentration of herbicides in crops, and timely irrigate to promote the transpiration of wheat and reduce pesticide damage. Field irrigation water can also be used to continuously flush with fresh water, or combined with drainage to put lime and other methods to neutralize the acidic herbicides in the field and reduce the pesticide damage.

For the pesticide damage on the plant, the toxic residues on the plant can be washed away by sprinkler irrigation machinery or spraying equipment, and the poison attached to the leaves can be reduced. 2. Strengthen fertilizer and water management: when the pesticide damage is light, some leaves of crops appear brown spots, and the heart leaves are not dead, and some leaf losses can be compensated for by strengthening fertilizer and water management, and they can generally be recovered in a short time.

After 7-10 days of glyphosate, vegetables can be planted. The residual time of glyphosate in the soil is relatively short, and it will quickly combine with iron, aluminum and other metal ions after contact with the soil to lose its activity, or be decomposed by soil microorganisms.

It can be cleaned with a professional fruit and vegetable cleaner, or soaked in light salt water, but it must be more than 10 minutes, and basically the pesticide residue will be reduced to the edible range.

Edible vegetables can be eaten in the ground for a long time, and the drug residue will disappear.

Generally, it's better not to eat, but if you have to eat, then you have to wash it well.

As with pesticides, rinse repeatedly under running water.

Of course you can't eat it, the vegetables will be killed by herbicides.

It's best not to eat it, and if you want to eat it, wash it well.

Carbendazim is a broad-spectrum fungicide, which has a control effect on diseases caused by fungi (such as semi-known bacteria and polyascomycetes) in a variety of crops. It can be used for foliar sprays, seed treatments, and soil treatments. Carbendazim can be used to control sclerotinia sclerotinia when the flowering rate of the main stem of rape reaches 80%, and boron fertilizer can be sprayed at the same time, and if necessary, it can be sprayed again after 7 days.

In many areas, the sclerotinia sclerotinia has generally developed a high level of resistance to carbendazim, and carbendazim alone should not be used alone to prevent and control sclerotinia in these areas, and it is advisable to switch to drugs such as pyridoxamine, pythium, sclerotinia and sclerotiorum, or mix these drugs with carbendazim. Oilseed rape is a boron-deficient crop and is sensitive to boron throughout its growth and development. In order to prevent boron deficiency in rapeseed, it is advisable to apply borax kilograms per mu, and at the same time, according to the degree of boron deficiency in the soil, boron fertilizer can be sprayed 1 2 times at the seedling stage, the sprouting stage and the flowering stage, and 50 100 grams of borax plus 50 kg of water per mu each time are sprayed.

No. Each pesticide has a safe residue period, during which it cannot be eaten, and it is safer to clean it before eating.

You can put the vegetables that have just been sprayed with pesticides into the ultrasonic cleaning machine, add water, and under the action of ultrasonics, countless tiny cavitation bubbles will be generated in the liquid. Once the bubble is formed, it bursts immediately. This process produces a strong impact that knocks and peels off the stains on the surface of the object to achieve an efficient cleaning effect.

Vegetables sprayed with pesticides can be eaten after washing.

Generally speaking, pesticides can destroy harmful substances such as insects and bacteria when applied to vegetables, but some pesticides may penetrate into the vegetables. In order to avoid immediate consumption in a short period of time, it can be washed and eaten after the medicinal properties of the pesticide disappear, so as not to cause adverse effects on the body.

Choose to eat fresh and healthy vegetables in your daily life, and avoid excessive consumption to avoid discomfort such as bloating and abdominal pain.

You can eat it in about two days, because the pesticides used in spraying vegetables are generally sterilizing, less toxic, and harmless to people, but you should also pay attention when eating; If it's greens, for example; Spinach and rape should also be washed several times. If it's turnips, potatoes or something. Peel and wash it before eating, so that after it is fried, it is basically non-toxic.

I've been eating it for more than 20 years, do you think you can eat it?

How many vegetables and fruits have not been pesticide-treated now??

If you haven't used pesticides, your appearance must be ugly and ugly, and some will have insect eyes or something, will you buy them??? Which one is not to pick up the nice and pleasing thing to buy now???

It depends on what vegetables, as well as pesticide residues, now fruits and vegetables are basically pesticides, and the vegetables you buy in the vegetable market, except for the particularly expensive pollution-free vegetables, have been sprayed with pesticides, as long as they are handled properly, there is no big problem. Soak in water for half an hour before eating, and wash it off. However, leeks are the hardest hit areas of pesticides, belonging to the flood irrigation type, and the pesticides are all inside, so eat less.

Celery is pesticide-free because no bug loves to eat celery.

Of course, you can eat vegetables and fruits that have been sprayed with pesticides. As long as it is not the kind of black-hearted businessman, he directly injects pesticides into vegetables and fruits with syringes. Just spray pesticides on the surface of vegetables and fruits, in fact, as long as we wash them with water before eating, there is not much of a problem.

After all, pesticides are diluted, and it is impossible to pick and sell pesticides immediately after they have been sprayed. As long as it takes a long time, the pesticide residues on vegetables and fruits will volatilize into the air or be washed by rain, and the pesticide content will be reduced. Therefore, as long as we buy vegetables and fruits, wash them with water, and we can use them with confidence.

You can eat it, but you can't eat it right away, so it's okay to wait until the safe period is over!

The safety interval refers to the period from the last application to grazing, harvesting (harvesting), use, and consumption of crops, and the interval required from spraying to the maximum allowable residue. When using drugs in orchards, the interval between the last spraying and harvest must be greater than the safe interval to prevent poisoning of humans and animals. Fruits should not be eaten right away.

It is better to wait for more than a week, and it is better to have a heavy rain so that there is no residue of pesticides.

In recent years, many ** reports have made many people subconsciously imagine pesticides as too scary. I would like to say that,Pesticides have been invented and widely used around the world for more than a century, which is enough to prove that pesticides have good control effects on various pests in the process of crop production, while ensuring stable yield and quality of crops.

Even pesticides in biological agents are inevitably poisoned in such a short period of time.

So the right thing to do is to sort pesticides and ensure proper safety spacing. If most of the pesticides are sprayed for 7-15 days, they can be picked and eaten. In addition, vegetables bought from the market should be left for 2-3 days before consumption, as long as they can be preserved, or put a little edible alkali in a basin of water when washing vegetables, because most pesticides will decompose quickly under alkaline conditions.

Soak in alkaline water for a few minutes, then rinse with water.

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. Actually, some simple ways can be removed! Bubble with baking soda.

After pesticides are applied to vegetables, some pesticides can be absorbed through the roots, enter the plant body, and gradually spread to the leaves, stems, fruits and seeds, resulting in residues. The cleaning method is: buy back vegetables, put them in a wooden barrel or wooden basin, rinse them with water first, then change the water, put in a little baking soda for about 10 minutes, and then rinse them with water several times to remove the residual organophosphorus pesticides on the vegetables.

Note: Salt water can kill insects, but do not soak the insecticide in salt water. This is unscientific. Instead, most pesticides are locked onto the surface of the vegetable.

Vegetables that have been sprayed with pesticides should be washed very thoroughly before they can be eaten.

At the very least, it will take about three days, and then you must wash it several times when you wash it.

I think that vegetables that have been sprayed with pesticides are ripe and cleaned and ready to eat.

At the very least, wait until the vegetables are ripe. Then be sure to wash it properly.

The vegetables sprayed with Bordeaux liquid cannot be eaten for the time being, and it takes about 7-15 days for the medicinal properties to disappear, and you can eat them after the time has passed.

Bordeaux slurry is generally used to control grape anthracnose, white rot, black pox, downy mildew, etc. during the hard core period of fruit heading (late July to early August). Before use, 80% mancozeb should be sprayed once, and 10-15 days after spraying, spray once with half amount of Bordeaux solution.

The spraying must be uniform and meticulous, and the fruit and cob must be sprayed. After coloring, pollution-free pesticides should be used, and Bordeaux liquid should not be sprayed again. After fruit picking, the lime equivalent Bordeaux liquid (1:1:200) can be used for control.
