In the past, the grain yield was not high, in addition to the low degree of seed improvement, in fact, many times it was because there were many insects in nature, and they liked to eat crops. At that time, people had to think of a lot of ways to prevent insect pests, and now after the invention of pesticides, many farmers can maximize their profits as long as they spray pesticides before or when they find insects.
Although pesticides can effectively inhibit insects and prevent insects from eating crops. But I have to say that pesticides kill insects at the same time, it may also remain on crops, if we are not careful to eat it, it will be harmful to our human body.
Next, let's talk about what methods can be used to remove pesticides. The first one is pesticide degrading enzyme, which is actually detoxified by hydrolyzing the phosphorus ester bonds in the organophosphorus pesticide molecule, because the pesticide degrading enzyme can react with the pesticides on the fruits and vegetables with pesticide residues, and destroy the structure of his highly toxic components through chemical reactions, turning the original toxic things into small molecules that are not toxic and can be dissolved in water.
The second more primitive method is to peel off the skin of some vegetables or peel them, generally pesticides are present in the outside of vegetables, and there are relatively few left in the vegetables, so as long as the skin of the residual pesticides is removed. Of course, there are some people who choose to soak in water, and many pesticides are acidic and water-soluble. So we just need to soak them in water, dilute them, and change the water a few more times, then the pesticide residue will be less and less.
The third is to use biological cleaning, which is actually to extract edible biological proteases from some organisms, and then use the activity of proteases to destroy pesticides. This method can achieve high efficiency and deep removal of pesticide residues in fruits and vegetables.
In fact, no matter how to remove pesticides, it is only a symptom, and if we want to solve this problem fundamentally, then we must solve the problem of pesticide use. No matter what pesticides are used, we must follow the requirements of the national guidelines for the legal use of pesticides, so that the majority of consumers can eat at ease, eat at ease, and hope that the relevant departments can increase supervision. After all, the people take food as the sky, and we must solve the most fundamental food safety problem for the people.

Pesticide degrading enzymes, which can solve many problems, can also be used to remove or peel off the skin of the plant, which can also be effectively avoided, you can choose this way of biological cleaning.
-
For example, there will be a lot of pesticide residues on plants, and then sometimes there will be some water pollution, and then there will be some pesticides, sometimes there will be herbicides, and then sometimes there will be biological enzymes.

Summary. Pesticide residue degradation technology is the first bioremediation technology of Nanjing Agricultural University, which can not only eliminate pesticide residues on the surface of agricultural products such as fruits and vegetables, but also degrade pesticide residues in soil, water and crops on a large scale.
What are the "nemesis" of pesticide residues?
Hello, pesticide residue buster has just come out of a pesticide residue degradation technology.
Can you buy it in**?
This technology can not only dissipate pesticide residues on the surface of agricultural products such as fruits, vegetables, etc., but also degrade pesticide residues in soil, water and crops on a large scale.
Is it available on JD.com?
What is a name brand called?
Dear, you can buy it on JD.com.
Pro, fruit and vegetable purifier, food washing machine, household sterilization, portable wireless pesticide residue removal automatic vegetable washing machine.
Roger that. Is there a potion that can reduce pesticides?
Dear, there is no one at the moment.
Dear, it's not safe to soak in the potion.
-
In general, everyone is removed by washing with water or some other cleaning solution, and different pesticides are actually removed in different ways.
-
First, wash the vegetables with clean water and then soak them in alkaline water to remove pesticide residues.
-
At this time, you can rinse it off with running water, and you can also use some fruit and vegetable cleaners, and you also need to wipe it clean with a dry towel or kitchen paper.

How to reduce pesticide residues? What do you know?
We all know that pesticides are used when planting crops, so there will be pesticide residues in the fruits produced, so how to reduce pesticide residues? What do you know?
The first point is to select the most effective pesticide products according to the characteristics of diseases, insects and weeds. timely use of pesticides; Strictly control the dosage, spray pesticides according to the dosage specified in the pesticide label, and spray pesticides evenly and carefully on crops to avoid repeated spraying and missed spraying; Strictly control the application concentration, dosage and use method of pesticides. In real life, rice washing water has a good pesticide effect.
Simple, convenient, easy to implement, and effective.
The second point is that milk powder and WP powder residues are low. It is necessary to choose low-toxicity, fast-decomposition drug varieties, and strictly control the dosage, use concentration, use method, number of use and prohibition time. The last use time before harvest is strictly observed.
According to the principle of safety interval and early treatment of various pesticides, early application of pesticides in the crop growth stage, pest juvenile stage and bacterial initial infection period can greatly reduce the amount of pesticide residues.
The third point is to choose low-toxicity pesticides, there are many types of pesticides on the market, in order to maintain land resources and the environment, the relevant departments of the state have banned the production of high-toxicity pesticides, so most of the high-toxicity pesticides on the market have been replaced by low-toxicity pesticides. Moreover, with the upgrading of pesticides and the improvement of production technology, the effect of these low-toxicity pesticides is not better than that of previous high-toxicity pesticides. Therefore, the selection of low-toxicity pesticides is the most basic work to reduce pesticide residues.
The fourth point is to strictly grasp the standards for the use of pesticides, and the dosage of different pesticides is different. The dosage of various pesticides to the control object is determined after testing by the technical department. The amount of the selected pesticide cannot be increased arbitrarily, nor can the number of uses be increased arbitrarily.
If the dose is increased at will, it will not only cause the waste of pesticides, but also produce the harm of drugs.
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. >>>More

When it comes to fruits and vegetables, we have to say "pesticide residues". According to the survey, in rural areas, 1.8 million tons of pesticides and 60 million tons of fertilizers are put into the environment every year. Which vegetables are high in pesticide residues? Which vegetables are easy to medicate? >>>More

The harm of pesticide residues to the human body every day is rooted in nutrients from food to meet the needs of the body, according to the Chinese Nutrition Society recommends that the human body needs about 1 kg of vegetables and fruits, vegetables and fruits are the main vitamin C, and the types of pesticides we residue every day are mainly organophosphorus and organochlorine. Eating a small amount of residual pesticides will degrade the human body itself and will not suddenly cause acute poisoning, but long-term consumption of agricultural products with residual pesticides will inevitably bring great harm to human health. The hazards are as follows: >>>More
