Does tea have pesticide residues, and the reason why there are many pesticide residues in tea

Generally, many tea farmers will use pesticides for the sake of yield. And whether this tea has pesticide residues or not, it is difficult to identify. Therefore, if you want to drink safe and pesticide-free tea, and in order to reduce the risk of pesticides and heavy metal residues in tea as much as possible, it is recommended that you can book tea at Hospitality Jiupin.

However, the annual tea production of Hospitality Jiupin is small, and it needs to be booked in advance!

In addition, in the brewing process of tea, the brewing of high-temperature water in the process of washing tea and waking up tea will make pesticide residues inactive, and a small part of pesticide residues that can be dissolved in water in a short time will be filtered out. Therefore, it is safer and more reliable to drink customized tea.

When we hear about pesticides, we are all apprehensive, because the damage caused by pesticide residues is not only acute poisoning, but also slow poisoning, carcinogenicity, teratogenicity and mutagenicity. Because of the slow progression of these damages, they are often overlooked and more damaging to the human body. Nowadays, when cultivating tea, pesticides are sprayed, and pesticides are sprayed to control pests and diseases and promote the growth of tea.

As far as tea is concerned, in the process of picking, manufacturing and transporting tea, although there is a series of treatment processes, pesticide residues will inevitably still exist. Therefore, when drinking tea, it is better to be able to buy tea leaves without pesticide residues as much as possible. If you want to buy safe tea without pesticides, you can book it on Hospitality Nine Pins.

Nowadays, when growing vegetables and fruits, pesticides are sprayed to control pests and diseases and promote the growth of vegetables and fruits. The same is true for tea, tea trees will also be sprayed with pesticides in the planting process, so that the tea will contain pesticide residues, for tea, in the process of tea picking, production and transportation, although there are a series of treatment steps, but pesticide residues will inevitably still exist. Therefore, in the process of brewing tea, it is necessary to remove the pesticide residues that may be contained in the tea as much as possible.

In the process of making tea, the brewing time of the first brew is generally controlled within 3 seconds, and then the first brew of tea soup is poured away, which is called tea washing. Tea washing is to remove pesticide residues and impurities that may be contained in tea leaves. Generally, pesticide residue residues can be detected with a portable pesticide residue detector.

Now there will be pesticide residues in the food generally, many people see vegetables and fruits with skin will choose to peel off the skin of the surface, feel that this will reduce the pesticide residues, in fact, for pesticide residues, is also a very common thing now, tea is no exception, in order to ensure the yield of tea to remove some pests, weeding, tea farmers will spray pesticides on the tea, but some are in the national standards, some tea will exceed the standard, but also flow to the market, so this has caused people's panic. We all know that pesticides are difficult to eliminate from the body, and long-term accumulation will cause great harm to the body, so in order to avoid such problems, it is still necessary to have a way to select tea.

So is organic tea a safe tea?

Now it is popular to drink organic tea, because we pay more and more attention to physical health, so we are very concerned about health care, green organic tea has gradually aroused people's attention, green organic tea is a kind of tea without pollution, high vertical degree of clean tea, because it is not suitable for chemical fertilizers, it is considered to be pollution-free tea, and it does not use any synthetic fertilizers, pesticides, chemical food additives and other substances at all, and uses human and livestock manure, so it is more delicious, and it is also certified by the relevant agencies on the shelves. However, the ** of green organic tea is high, and it is still difficult to fully popularize it.

So what problems should we pay attention to when buying tea to minimize such worries?

1. Buy tea from regular channels, don't go to that kind of stall vendor to buy tea, such tea is likely to be excessive pesticide residues of tea, cheap**, don't be greedy to buy such tea, not only is it not good for the body, long-term drinking will also lead to the production of diseases of the body, then it loses the meaning of drinking tea.

2. Drink only tea, don't chew tea leaves. Many people like to chew the tea into it, eat it, and think that it will be better for the body, in fact, there will be pesticide residues in the common tea now, but the water solubility is very low, even if there is negligible, but the substances in the tea still exist, so just drink the tea, don't eat the tea. <>

3. Don't go without changing the water for a long time. Drinking tea must be drunk frequently, add water frequently, so that the pesticides in the tea will not penetrate out quickly, so that you can avoid drinking more pesticide residues.

Some people can worry about the talent and medicine residues on the tea, and now no matter what they plant, it is difficult to endure. He is to prevent the degree of tea, so you put some pesticides on the tea, as long as you look at it, as long as you are there. When you buy it, you want to buy this kind of tea, you can cast it again, and wash the tea when you flush it, so that you can remove it.

Do not worry. Pesticide residues on tea leaves.

Since the tea is imitated with pesticides, there will be more or less residues, but pesticide residues and pesticide residues exceeding the standard are two different things. The national Yun nationality cave is allowed to use low-toxicity pesticides on tea.

I think there will be some pesticide residues on the tea, well, the tea is the same as other things, it will go bad if you don't spray it.

Summary. One is illegal drugs.

The second is overdose.

The third is over-the-range medication. Pesticides registered for use on other crops are used on tea plants, resulting in residues.

Fourth, the same pesticide is used frequently and repeatedly, and the bioaccumulation leads to pesticide residues.

Fifth, the safety interval is too short, and the pesticides remaining in the tea are not fully degraded.

Sixth, the application of compound (mixed) pesticides containing unspecified ingredients has led to the exceedance of some pesticides.

Seventh, apply pesticides in the edge fields. Contamination by chemical drift.

Eighth, the soil and irrigation water of the tea garden are polluted by pesticides, and the reason for the large number of pesticide residues in tea.

Hello, dear. There are several reasons for pesticide residues in tea.

First, the substance liquid circle violates the prohibited drugs. The second is overdose. The third is over-the-range medication.

Pesticides registered for use in other crops are used on tea plants, resulting in residues. Fourth, the same pesticide is used frequently and repeatedly, and the bioaccumulation leads to pesticide residues. Fifth, the safety interval is too short, and the pesticides remaining in the tea are not fully degraded.

Sixth, the application of compound (mixed) pesticides containing unspecified ingredients has led to the exceedance of some pesticides. The seventh is the application of pesticides in the edge fields. Contamination by chemical drift.

Eighth, the soil and irrigation water of the tea garden are polluted by pesticides, why are the pesticide residues in tea more serious than other agricultural products?

1.Although pesticides such as "666" and "Dishui Didi" have long been banned in China, experiments have found that because a large number of rice fields are in use, the pesticides sprayed on the rice fields will absorb the dust in the air and drift to the tea plantations. In addition, some persistent pesticides used in the past were left in the soil, causing plants to absorb some of the residues from the soil, so pesticide residues were detected in the tea.

2.Most of the tea farmers' land is planted in a decentralized manner, and even if they don't use pesticides, they will be polluted by the drift of nearby pesticides, and they will not be able to form a series of pests and diseases.

3.Consumers want cost-effective tea, tea merchants can only squeeze the purchase price, and farmers can only plant with lower fiber oranges, which not only causes pesticide residues, but also causes harm due to the abuse of chemical fertilizers and herbicides.

So how do you think we should subsidize agricultural production in order to ensure that the problem of agricultural residues in China's agricultural products can be effectively solved.

Green is the true color of agriculture, and green development is the basic requirement of agricultural supply-side structural reform. ”

1. Subsidy policy for cultivated land fertility protection.

2. Subsidy policy for the purchase of agricultural machinery.

3. Pilot policy of subsidy for scrapping and updating agricultural machinery.

4. Strengthen support policies for the construction of high-standard farmland.

5. Supporting policies for the creation of counties for the quality and safety of agricultural products.

6 Supporting policies for replacing chemical fertilizers with organic fertilizers for fruits, vegetables and tea.

7. Support policies for zero growth in the use of chemical fertilizers and pesticides.

People who like to drink tea in life often make tea and drink, and may not have noticed the health problems of tea, but it is worth our attention that there may be pesticide residues on the tea, and we must pay attention to it when making tea, we can pour out the water that made tea for the first time, and then brew it again. So, are there pesticides on tea? How to reduce pesticide residues in tea?

1. Are there pesticide residues on tea?

In some old tea areas, the inspection and specification of pesticides are relatively strict (generally pesticides sprayed on vegetables), and most of the pesticides are low-toxicity or non-toxic. But it's still a little bit of a residue.

2. How to reduce pesticide residues

Many pesticides are fat-soluble, adsorbed on the tissues of tea leaves, and do not easily migrate into tea water. Even if these tea leaves have a little pesticide residue exceedance, there are very few people who really drink it with the tea soup. Therefore, drinking only tea and not chewing tea further greatly reduces the risk of pesticide residues in tea.

3. Tips

Many people drink tea and pour out the first brew of tea, which is called "washing tea", which feels like washing away the dust on the surface. In fact, if the tea is dirty, there is no way to wash it. It is recommended to go to the regular channel to buy clean tea, "tea washing" is actually not very meaningful.

4. The wonderful use of tea

1. Trick 1: Eliminate dark circles.

The main causes of dark circles are lack of sleep, overuse of the eyes, or lack of vitamin B12. Wrapping the tea residue in gauze and applying a warm compress to the eyes can eliminate temporary eye puffiness and dark circles caused by staying up late and edema.

2. Clever use two: do **.

Tea contains tannins, which increase skin elasticity and help moisturize the skin. In addition, tea also has a bactericidal effect, and has a certain effect on acne and suppuration. Dry**Can be made with green tea with egg yolk and honey**, and egg white is suitable for sensitive skin.

3. Trick 3: Take a bath.

Green tea has a bactericidal effect, can deeply cleanse the skin, soften the stratum corneum, and make the skin delicate and white. Put the remaining tea residues after drinking tea into a cotton bag after drying, tie the bag tightly and put it into the bathtub, and the skin will feel soft and tender after taking a green tea bath.

4. Trick 4: Wash your hair.

Washing your hair with water soaked in tea residue can remove excess dirt from your hair, making it black, soft, shiny and shiny. After normal shampooing, rinse your hair with tea to nourish your hair.

5. Wonderful use five: adsorption of odor fiber Zen.

Dry the leftover tea residue and put it in a gauze bag and put it in the refrigerator to get rid of the fishy smell of fish, meat and other foods. It can also be used in the kitchen and toilet to remove odors. Placed in the shoe, it can eliminate the dampness and odor in the shoe.

6. Clever use six: moisture-proof.

Dry the leftover tea residues in the sun and spread them in a damp place in the room to remove moisture. Because tea has a strong adsorption effect.

7. Magic use seven: go greasy.

Scrubbing greasy pots and pans, or wooden or bamboo tables and chairs with leftover tea residue can effectively remove greasy and make them smoother. Greasy kitchen rags can be cleaned with boiling water for tea residues.

Generally, tea is not pesticide at all, especially green tea, but some teas, in some seasons, have more insect pests, and it is possible to spray, but strictly control the safe period of picking, and there will be no pesticide residues.

Tea is a drink that originated in China and is made from the leaves or buds of the tea plant. It also refers to the leaves of the evergreen shrub tea tree that can be used to make tea, as well as the drinks brewed from these leaves, and later extended to all herbal teas brewed with plant flowers, leaves, seeds, and roots, such as "Tieguanyin" and so on. As a well-known health drink, tea is the contribution of the people of southern China to the Chinese food culture in ancient times, and it is also the contribution of the Chinese people to the world's food culture.

(1) Rational use of pesticides According to the nature of pesticides and the occurrence of diseases and insects, the rational use of pesticides can obtain the maximum control effect with the least dosage, which can not only use drugs economically, but also reduce environmental pollution. This needs to start from the aspects of prescribing the right medicine, mastering the correct application amount, improving the efficacy, reducing the dosage, rationally mixing pesticides, and rationally deploying pesticides.

According to the EU standards from 2003 to 2008, the standards for 9 kinds of pesticides, such as avermectin, dimethoate, oxymethoate, tetradimetrazine (Apollo), deltamethrin, quinthion, pyrethon, thiazinone (Eured) and pyridafenone (pyridafen), are very strict, so they should be stopped for use in the export tea production base. Due to the high water solubility of dimethoate and oxymethoate, most of the residual pesticides in the tea will be leached when making tea, so the use should be stopped. Acemethamidophos is oxidized and metabolized into methamidophos on tea plants, and the EU standard is milligram kilograms, so it should be discontinued in tea production.

2) The safe use of pesticides should be formulated to allow the maximum residue of pesticides in tea, the safety interval should be formulated, high-residue pesticides should be banned, and the safe use standards should be formulated to improve the level of scientific drug use.

3) Adopt poison avoidance measures to improve the cultivation system, strengthen agricultural control, biological control and other measures, implement comprehensive management of tea garden diseases and pests, and reduce pesticide pollution.

4) Develop environment-friendly pesticides Starting from the source of production, we vigorously advocate the use of biological pesticides (including microorganisms, plant sources, and mineral pesticides) to reduce the pollution of tea and its ecological environment while inhibiting pests and diseases.

5) Strengthen agricultural control, carry out biological control, supporting physical control, coordinate chemical control, and implement comprehensive management of diseases, insects and weeds in tea gardens.
