Can you eat a dish that has been sprayed with pesticides in 3 days It has rained twice

Be sure to find out what pesticides are sprayed, all pesticides that are allowed to be sprayed on vegetables can be harvested and eaten after 7 days, and some pesticides need 15 days or longer, which is explained in the pesticide instructions.

For safety, take care to wash and soak.

Most pesticides are organophosphorus, which is acidic and unstable and easy to decompose in an alkaline environment. After decomposing, of course, rinse it off, so you don't have to eat it in your stomach!

In the production process of pesticides and other toxic substances, some oily carriers should be added so that they can effectively adhere to the surface of crops when sprayed and used, so as to achieve the purpose of killing pests. These toxic residues and other germs cannot be washed away with clean water alone. Dishwashing detergent contains a variety of active substances and emulsifiers, which can turn various stains and harmful substances into emulsions dissolved in water, and rinse them away with water.

In addition, dishwashing detergent also contains sterilizing and disinfecting ingredients, and when used in moderation, it can remove microorganisms that are harmful to people and keep bacteria out.

It depends on the type of pesticide, and the safety period of some pesticides.

In more than 15 days, some will be fine for a day or two.

As long as it doesn't rain a few hours after the medicination, it doesn't have much to do with the rain.

*No**. Vegetables that have been sprayed with pesticides need to wait at least 7 days before eating, and if they are moderately toxic or have high concentrations, you need to wait about 15 days. After two rains, vegetables may be affected by drug residues, so safety when consumed is not guaranteed.

In the rainy season, it is enough to spray the fungicide every 7-10 days, and there is no need to spray the fungicide every time it rains. In the season when there is less rain, fungicides can be sprayed on the 2-3 days after the rainfall to prevent diseases.

6 hours after the insecticide is sprayed, 12 hours after the fungicide is sprayed, and then rain does not have much effect on the efficacy of the drug. After spraying pesticides, rain has a greater impact on the efficacy of fungicides (after being washed by rain, it loses its protective effect), and if the rainfall is heavy within 12 hours, it is best to spray again.

It will work, and the potion will generally work in an hour to two hours, even if it rains, it will not affect the effect.

Yes, but the effect is not great, and it takes some time to absorb. Respraying is recommended.

The best time to spray fungicides should be decided according to the season, summer and autumn are generally more suitable after 10 am and 4 pm, and winter and spring are generally 2-4 pm is more appropriate. In addition to the appropriate time, attention should also be paid to the concentration of the spray, the safety period of the fungicide and the standard of mixed use. The fungicide generally has no effect on rain after spraying for 4-5 hours, but it also depends on the actual situation.

First, the best time to fight fungicides.

1. The spraying time in different seasons is not the same, in the summer and autumn high temperature season, the spraying should be selected after about 10 a.m. and 4 p.m. on a sunny day, because around 10 a.m., the leaves of fruit trees and crops are generally dewy and dry, and the temperature is not too high, and at the same time it is the most vigorous time for pests and diseases, and the spraying effect is better at this time; After 4 o'clock in the afternoon, the light gradually weakens, the temperature gradually decreases, and the nocturnal pests whiteflies and thrips begin to move.

2. In the low temperature season of winter and spring, the spraying time is appropriate at 2-4 o'clock in the afternoon, because the temperature is low in winter and spring, after the leaf dew recedes in the morning, photosynthesis gradually enters the peak period, if spraying in the morning will inevitably affect the increase in temperature and reduce the photosynthetic efficiency, so it is not suitable to use medicine in the morning. When spraying, in addition to choosing the right time, we should also pay attention to the concentration of spraying, the safety period of the fungicide, the standard of mixing and the size of the droplets.

If it's light rain, it doesn't matter if it doesn't rain for long.

If the rain is heavy or light for a long time, it is recommended to make up for it once after the rain is clear.

1. Vegetables that have been sprayed with pesticides can be eaten in a few days.

1. The pesticide residue attached to the vegetables will slowly evaporate after about 5-7 days, and it can be eaten after the effect is completely volatilized. But it is necessary to draw conclusions based on which pesticide is used, and if it is highly toxic, such as methamidophos.

Pesticides such as carbofuran and methocarb are not recommended to be consumed.

2. For the sake of safety, it is best to soak the residual pesticides attached to the vegetable leaves with detergent for 10-15 minutes, or soak them in water for 30-60 minutes. However, soaking with detergent will remove pesticides faster.

3. Fruits and vegetables should be rinsed before soaking, that is, the fruits and vegetables should be thoroughly cleaned and then soaked in water for 10 minutes, but do not soak for too long to avoid the surface pesticides entering the water and returning to the inside of the fruits and vegetables.

2. Can vegetables be eaten after 4 days of pesticides?

1. It is best not to eat the vegetables that have been sprayed with pesticides after 4 days, because the pesticide residues on the vegetables have not completely volatilized at this time, which will affect their own health, and in serious cases, it will also have a negative impact.

2. Generally, it is necessary to wait for 5-7 days after spraying before all can be volatilized, and at this time, for safety, it is necessary to soak the vegetables with detergent for a period of time, or soak them in water for about 1 hour before eating.

3. If you are spraying a high-efficiency and low-toxicity pesticide, you can generally eat it after about 7-10 days of medication, but if it is moderately toxic, you need to eat it for about 15 days, and if you spray vegetables with higher concentrations, you need to wait longer, or even can't eat.

Vegetables will have insects to eat vegetables in the planting process, so almost every vegetable needs to be sprayed to drive away vegetable insects to ensure the healthy growth of vegetables, but because vegetables have a certain toxicity after spraying, insects will die after eating, people can also not eat, the vegetables that have been sprayed need to wait for a period of time to be not toxic before they can be eaten, so how many days can vegetables be eaten after spraying?

The key depends on what kind of pesticide is being used. If it is highly effective and low-toxic, it can be eaten 7-10 days after taking the drug; If it is moderately toxic, it can be eaten after 15 days after taking the drug; Vegetables that have been sprayed with high and high residue pesticides can not be eaten for a long time, such as: methamidophos, parathion (1605), methionphos (3911), carbofuran (carbofuran), monocrotophos, methylisosulfonphos, methocarb, hexacarb.

Six. Sixth, trichlorfon and so on.

Usually the pesticide residue attached to the leaves will evaporate in five days to a week, but it is best to soak it in detergent for 10-15 minutes or in water for 30-60 minutes to be on the safe side. Soak with detergent and the pesticide is removed faster.

With the continuous progress of cultivation technology, the growth period of vegetables has become shorter and shorter, and with the intensification of environmental pollution, the pests and diseases of vegetables are becoming more and more serious.

Leafy vegetables were heavily polluted by pesticides, among which leeks and rape were polluted in the largest proportion. Nightshade vegetables such as green peppers, tomatoes, etc., young pod vegetables such as beans, bulb vegetables such as onions, garlic, onions, etc., the pollution of pesticides is relatively small, but some are relatively large.

Try to buy fruits and vegetables in the regular market with health supervision, and the product packaging has one of the four marks of "quality and safety", "pollution-free products", "green food" and "organic food", which is relatively safe and reliable.

Fruits and vegetables should be rinsed and then soaked, that is, the fruit and vegetable surface should be thoroughly cleaned and then soaked in water for 10 minutes, but not too long, so as not to return to the inside of the fruit and vegetable after the surface pesticide enters the water.

Vegetables and fruits are prone to disease damage in the whole process of planting, and under normal conditions, they are carried out according to spraying pesticides. Now there are many vegetables and fruits that need to be sprayed, vegetables and fruits can be eaten after a few days of chemical fertilizer, can you eat it after spraying for four days, it seems!

Vegetables and fruits have been fertilized for four days is best not to eat, if you have just been fertilized, the fertilizer of vegetables and fruit leaves will remain to five days or a week, but even if you eat a week later, you need to soak in water for fifteen minutes, and use detergent, if you soak with cold water, then you need to soak for an hour.

In fact, whether you can eat chemical fertilizer, mainly depends on what fertilizer is played, if it is high-efficiency and slightly toxic, it can be eaten in seven to ten days after taking the medicine, but if it is a medium-level poison, you need to eat it after fifteen days of taking the medicine, if you spray vegetables and fruits with higher concentration values, you need to wait longer, and some can not even eat.

The vegetables and fruits we buy today are basically all chemical fertilizers, and only chemical fertilizers can be used to avoid small insects in vegetables and fruits, and the surface will also be very good-looking.

No matter where the farmers are spraying pesticides on vegetables and fruits, but the problem of how much is too much, if the fertilizer is used properly, we wash it several times in the case of eating, and there is no harm to the human body.

The above is the network combing about vegetables and fruits can be eaten after 3 days of chemical fertilizer, I firmly believe that according to the detailed introduction of the above network editor, everyone has already understood how many days the spraying can be eaten, no matter what kind of food, if it is a chemical fertilizer, it must be eaten after a period of time, otherwise it will affect the human body.

How to clean vegetables and fruits safely?

Generally, the residual fertilizer attached to the green leaves will evaporate in five days to a week, but it is best to soak it in detergent for 10-15 minutes or cold water for 30-60 minutes to be on the safe side. However, do not soak for too long to prevent the surface fertilizer from returning to the inside of the vegetables and fruits when the water enters the water.

With the continuous development of planting technology, the growth period of vegetables and fruits has become shorter and shorter, and with the aggravation of air pollution, the diseases of vegetables and fruits have also become heavier.

Leafy vegetables and fruits are heavily polluted by pesticides, among which amaranth and rapeseed suffer a relatively large proportion of environmental pollution. Solana vegetables and fruits such as peppers, tomatoes, etc., young pod vegetables and fruits such as long beans, bulb vegetables and fruits such as onions, garlic, shallots, etc., the environmental pollution of chemical fertilizers is relatively small, but some are larger.

In the end, the online editor reminded everyone: as far as possible to buy vegetables and fruits in a reliable sales market with a health supervision office, and the packaging design with one of the four labels of "product quality", "pollution-free goods", "emerald green food" and "organic chemical food" is relatively more reliable.

Vegetables can not be eaten after 4 days of pesticides, at least half a month later, but for the sake of safety, detergent soaked for 10-15 minutes, soaked in water for 30-60 minutes, soaked with detergent, pesticides are removed faster, soaked and scrubbed with water, pesticide residues can be reduced, and the longer the soaking time, the less pesticide residues.

Can you eat it according to the pesticide instructions? Different pesticide residue times are different, and the opinions expressed will be strictly stated. Eat as late as possible according to the instructions, wash it with water before eating, and use a cleaning agent that specializes in cleaning vegetables, which will wash off the drug residue and is good for the body.

Don't take it lightly.

Under normal circumstances, vegetables are sprayed with pesticides, and they can only be eaten after half a month. Otherwise, the residue of the pesticide will cause harm to the human body.

Can you eat vegetables after four days of pesticides? Vegetables can not be eaten after four days of pesticides, and they are also highly toxic, and they are not highly toxic pesticides.

This generally depends on the type of pesticide used.

But generally 5 to 7 days can be, and before eating, it is safe to soak in water for 30-60 minutes.

Different vegetables, different pesticides, and different seasons have different safety intervals.

According to the regulations promulgated by the Ministry of Agriculture, the safety interval of several commonly used pesticides in vegetables is:

2. With 90% solid trichlorfon solution, the interval between the bases shall not be less than 7 days, and the autumn and winter shall not be less than 8 days.

3. Dichlorvos is not less than 7 days, and autumn and winter are not less than 8 days.

4. Phosphine is not less than 5 days.

5. Carbaryl is not less than 7 days.

6. Kill pine for not less than 10 days. For pesticides that have not yet been specified, generally not less than 5-7 days in summer, not less than 8-10 days in spring and autumn, and not less than 10-15 days in winter.

China's Ministry of Agriculture has promulgated some pesticides in different vegetables to use the safety interval, for the pesticide varieties and vegetable varieties that have not yet made specific provisions, the current general implementation method is:

The temperature is high in summer, the toxicity of pesticides disappears quickly, and the safety interval after pesticide application is 5 7 days, at least 7 10 days in spring and autumn, and more than 15 days in winter. The basic principle that should be grasped is that when the pesticide toxicity is large, the dosage is large, the concentration is high, and the temperature is low, the safety interval harvest period should be longer; Conversely, it can be shorter. Vegetables should never be picked immediately after application.

<> taking herbicides as an example, if it rains more than 6 hours after spraying, the efficacy of the herbicide will usually not be affected, and if it rains within 6 hours after application, you can observe the growth of weeds for a period of time, and decide whether to respray according to the specific situation. If the pesticide is to be re-sprayed, the dosage of the drug should be appropriately reduced, or other herbicides should be sprayed to avoid pesticide damage and ensure the effect of the application.

1. Is it effective to rain with pesticides?

1. There are many types of pesticides, and the efficacy is also different, taking herbicides as an example, if it rains after 6 hours after spraying, it will generally not affect the efficacy, if it rains within 6 hours, you can first observe the growth of weeds for 1-2 weeks, and decide whether to re-spray according to its growth.

2. If the rainfall is more, reaching the level of moderate rain and above, the water content of the soil in the field at this time is more, and the water absorbed by the plant will also increase, which will cause the drug absorbed by the weeds to be diluted by the water.

3. When there is more water in the plant, the transportation efficiency of the drug in the body will be affected, and in this case, it is generally necessary to re-spray the drug to achieve the weeding effect.

4. If it is necessary to re-spray, the amount of drug used should be reduced, or other herbicides with different effects should be sprayed, which can not only prevent pesticide damage, but also ensure the effect of pesticide application.

Second, the pesticide vegetables can only be eaten after a few days

1. If it is sprayed with low-toxicity pesticides, it can generally be eaten after about 7-10 days. If a toxic pesticide is sprayed, it usually takes about 15 days or more before it can be consumed. If you spray highly toxic pesticides (such as carbofuran, methocarb, methamidophos, etc.), it is recommended not to consume them.

2. If there are pesticide residues on the vegetables, they can be thoroughly cleaned first, and soaked in detergent solution for 10-15 minutes (or soaked in water for half an hour to 1 hour), then removed, and the residual drugs can be effectively removed after re-washing.

3. It is recommended to soak vegetables with detergent solution, which can remove residual drugs faster. It should be noted that the soaking time should not be too long to prevent the drug from entering the water and being re-inhaled by the vegetables.
