Are pesticides used in grapes harmful to humans?

*Pesticides used in grape beatings can be harmful to humans**. Most pesticides have varying degrees of toxicity, and if the human body ingests them by mistake, drug poisoning reactions may occur. However, if the grapes are thoroughly washed and consumed, there is no residue of pesticides on the surface of the grapes, and generally no harm to the human body.

In short, in order to ensure food safety, before eating grapes, the grape skin should be fully washed to ensure that there are no pesticide residues, deterioration, animal feces, etc. on the surface. If you accidentally eat grapes with pesticide residues, you should drink more water to promote metabolism, help the discharge of harmful substances, and pay attention to your own symptoms. If there are obvious manifestations such as dizziness, nausea, abdominal pain, etc., it is necessary to seek medical attention in time to receive gastric lavage**.

Any pesticide is harmful to the human body, don't rush to eat the grapes you bought, soak them in light salt water for ten minutes, and then wash them for use.

Most grapes are "bagged", and in order to "bag" they must be soaked in a "potion".

One serving of the potion is mainly divided into three sachets, namely pyraclostrobin, which is mainly used to prevent banana leaf spot disease; 22% of azole, the main role is to prevent penicillium and green mold in citrus; Difenoconazole is also used to prevent banana leaf spot.

It is allowed to be used by the state and is a low-toxicity pesticide.

Generally, it only takes 10 days for the pesticide content to drop to a reasonable range set by the state, and it generally takes more than a month for grapes to be harvested from bagging to ripening.

"Grapes generally have some pesticide residues on the skin of the wind, but red grapes have fewer pesticides on them because of the different methods of planting and care. ”

When people eat grapes, they often eat the skin except for seedless white grapes, and when they eat other grapes, they have to spit out the skin, because the grape skin has an astringent taste. But from a nutritional point of view, don't spit out the skin when eating grapes. Shed sleepy.

Grape skins are rich in resveratrol, a polyhydroxyphenolic compound.

It has the effects of lowering blood lipids, anti-thrombosis, preventing arteriosclerosis, and enhancing immunity.

Another important substance in grape skins – tannins.

It has the effects of anti-allergies, anti-aging, enhancing immunity and preventing cardiovascular and cerebrovascular diseases.

Anthocyanins contained in grape skins.

It has strong antioxidant, anti-mutation, alleviating liver dysfunction, protecting cardiovascular and other functions.

Grape skins also have anticancer effects, Illinois, USA.

Researchers at the University of Pharmaceutical Sciences found that this substance is present in more or less than 70 species of plants, such as peanuts and grapes, and is especially found in grape skins and red wine.

Growing grapes requires protection against pests and diseases, and pesticides must be used. Taking grape anthracnose as an example, since late April in the south and late May in the north, spraying is carried out for prevention and control, and then it is generally sprayed every 10-15 days, and 80% anthrax Fumei 700-800 times can be sprayed, 50% chlorothalonil 600-700 times liquid, 50% antibacterial special or mancozeb 800 times liquid. There is a lot of rain in the south, and 1500 times of "6501" or adhesives such as leather glue are added to the liquid medicine.

If it is to prevent and control grape white rot in the north, it is necessary to spray 5 degrees of stone sulfur mixture or 100 times chlorothalonil after the grapes are unearthed; At the beginning of the young fruit period (early June), spray every 15 days or so until harvest. In the south, it is necessary to grasp the inflorescence separation period (late April to early May), 7 days after flowering, and half a month before maturity, and the main agents are half, equal or double Bordeaux liquid, 75% chlorothalonil 800 times liquid, 50% carbendazim wettable powder 700 times liquid, 70% tobuzin 700 times liquid or 50% antibacterial holding 800 times liquid.

Of course, when people eat grapes, they often eat the skin except for seedless white grapes, and when they eat other grapes, they have to spit out the skin, because grapes.

The skin has an astringent taste. But from a nutritional point of view, don't spit out the skin when eating grapes.

Grape skin is rich in a polyhydroxyphenolic compound - resveratrol, which has the ability to lower blood lipids, anti-thrombosis, prevent arteriosclerosis, and enhance immunity.

epidemic capacity and other roles.

Another important substance in grape skin, tannin, has the functions of anti-allergic, anti-aging, enhancing immunity and preventing cardiovascular and cerebrovascular diseases.

Effect. The anthocyanins contained in grape skin have strong antioxidant, anti-mutation, alleviate liver dysfunction, and protect cardiovascular functions.

Grape skin also has anti-cancer effects, researchers from the University of Illinois Pharmaceutical Sciences in the United States found that this substance in peanuts, grapes and other more than 70.

Plants are found in a variety of species, especially grape skins and red wines.

Since most of the grapes on the market have the problem of pesticide residues, they must be cleaned before eating the grapes with the skin. Best.

Rinse with water and wash for at least two minutes with a detergent that can effectively remove pesticide ingredients. However, it is not advisable to soak in water and salt water, because the soaking of water is easy to promote the penetration of residual pesticides on the surface of grapes into the pulp.

Generally, it is best to hit stone sulfur mixture.

In the early spring of the grape budding, you can choose to give it stone sulfur mixture and other drugs, in the embryonic stage, leaf development period, flowering period and young fruit period of grapes can alternately use stone sulfur mixture, mancozeb and other drugs to prevent and control various diseases, under normal circumstances, grapevines can be sprinkled in spring around April, because at this time with the warming of the weather, the temperature gradually rises, overwintering pests begin to be active, to sprinkle pesticides in time to prevent and control pests and diseases, and commonly used insecticides for grapevine pests are dichlorvos, cypermethrin, etc.

Strengthen cultivation management, enhance tree potential, improve tree disease resistance, apply more organic fertilizer, maintain moderate and robust tree potential, appropriately increase phosphorus and potassium fertilizer, control nitrogen fertilizer, and improve tree disease resistance. Through pruning, the appropriate amount of branches and fruits should be left, the fruiting parts should be appropriately raised, and the branches and leaves near the ground should be removed. Frequently eradicate weeds under the grape trellis to facilitate ventilation and light, reduce microclimate humidity, and create environmental conditions that are not conducive to the occurrence of diseases.

Maintenance of vine drainage

The grapes prefer a warm environment, and when the temperature rises in spring, all growth and development will be significantly improved, and new shoots will soon sprout. In the later stage, it is necessary to control the temperature well. It is best to provide a temperature environment above 20 degrees Celsius, so that the flowers can bloom better, the fruit sets, and the fruit grows better.

If the temperature drops suddenly, and the temperature is not well controlled, the flowers will wither, and the fruit set rate will be greatly reduced, which will reduce the yield.

The vine is drought tolerant and does not need to be watered frequently during the cultivation period. Even during the growing season, wait for the soil to dry before watering. Watering too often will not absorb it, but will affect growth.

Therefore, watering it can be carried out according to the principle of not drying or watering, and preferring dry to wet. Vines are inseparable from fertilizer during the growth period, and it is necessary to fertilize them properly. The specific fertilization method should be based on the growth stage into the nucleus rotten line.

Of course, pesticides are used, so those who go to the site to pick grapes are unhygienic.
