The baby greens can be eaten after a few days of pesticides

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.

Extended Materials. 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 noodles should be thoroughly washed and then soaked in water for 10 minutes, but not too long, so as not to return to the inside of fruits and vegetables after the surface pesticides enter the water.

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; And vegetables that have been sprayed with high-level, high-residue pesticides cannot be eaten for a long time.

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.

Because pesticides have a safe isolation period for decomposition.

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 reduction. 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.

In order to ensure the quality and safety of agricultural products, it is necessary to pay attention to the safety interval of pesticides in the use of pesticides, that is, the number of days between the last application and the harvest of crops, that is, the date when pesticides are prohibited before harvest.

Only by applying pesticides during the safety interval can we ensure that the amount of pesticide residues does not exceed the standard and ensure the quality and safety of agricultural products. Different pesticides have different safety intervals, and they should be used in accordance with the provisions of the pesticide label.

Because pesticides have a safety interval, some are one week and some are two weeks, so you need not to use them for at least two weeks before picking.

Otherwise, you will be eating pesticides directly. Plants need time to decompose.

Because pesticides are toxic, they will dissipate a little after a few days, or you can soak them in salt water.

It should be about 5-7 days, and it is best to soak it in water before eating.

Distinguish the type of pesticide and ensure an appropriate safety interval, such as most insecticides spray after 7 to 15 days before picking and eating. Since pesticides have been invented and widely used all over the world for more than a century, it is enough to prove that they have a good control effect on various pests in the process of crop production, while ensuring stable yield and quality of crops.

In China, due to the limitations of farmers' knowledge level and other reasons, pesticides are used indiscriminately and abused, which is also the main reason for high pesticide residues.

Hello! It should be about 5-7 days, and it is best to soak it in water before eating.

When in doubt, please ask.

Vegetables that have been sprayed with pesticides can be eaten after 5-7 days.

Pesticides attached to vegetables generally remain in about 5-7 days and will slowly evaporate, and can be eaten after the effect is completely volatilized. But it is necessary to draw conclusions according to the specific use of pesticides, if it is a high-efficiency and low-toxicity pesticide, it can be eaten in about 7-10 days of medication, but if it is moderately toxic, it needs to be eaten about 15 days of medication, and if it is sprayed with a higher concentration of pesticides, it needs to wait longer, or even can not be eaten.

Residual pesticides attached to vegetable leaves are best soaked in detergent for 10-15 minutes or in water for 30-60 minutes for safety. However, soaking with detergent will remove pesticides faster. Fruits and vegetables should be rinsed before soaking, that is, the fruit and vegetable surface 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.

Vegetable washing method

1. Soak in salt water

Generally, rinse with water at least 3 or 6 times, and then put in light salt water.

Soak for 1 hour, then rinse with water 1 time. For the cabbage vegetables, you can cut them first and soak them in water for two hours.

2. Soak in alkaline water

Generally, edible alkali is added to 500 ml of water.

5 grams 10 grams are formulated into lye. Put the fruits and vegetables after the initial rinsing in alkaline water, mix enough alkaline water according to the amount of vegetables, soak for 5 15 minutes, rinse the fruits and vegetables with water, and repeat the washing about 3 times The effect is better.

3. Blanch with boiling water

Generally, the washed fruits and vegetables are placed in boiling water for 2 to 5 minutes, then removed immediately, and then washed with water once or twice, and then placed in a pot to cook into dishes.

Vegetables that have been sprayed with pesticides can generally be eaten in about seven to fifteen days.

After the vegetables are sprayed with pesticides, they can be cooked, and the time required for the disappearance of pesticides is about 7 to 15 days, if the concentration of pesticides is small, it can be eaten in about seven days, and if the concentration of drugs is large, it takes about 15 days to eat. The medicine is not cleaned or there are a lot of pesticide residues in the vegetables, which can cause poisoning after consumption.

The surface of the vegetable that has just been sprayed with pesticides is not absorbed, and the vegetables basically do not contain pesticides after sufficient cleaning, and can be eaten. It is recommended to soak vegetables that have been sprayed with pesticides before eating them in salt water and wash them with warm water before eating.

Pesticides can be used to kill insects, fungi and other organisms that harm crop growth. The earliest pesticides used were DDT, 666, etc., which can eliminate pests in large quantities. However, they have good stability, can survive in the environment for a long time, and continue to accumulate in animals, plants and humans, so they are eliminated.

Later, organophosphorus pesticides, such as dichlorvos, were used instead of the original pesticides.

Because they are too toxic, they are very harmful to humans and animals. In recent years, a number of high-efficiency and low-toxicity pesticides have appeared, with specificity, that is, hormone pesticides. Pesticides have advantages and disadvantages, good for plants, but accidental ingestion will cause potential safety hazards, I hope that the majority of pesticide users will be cautious.
