How can we effectively reduce pesticide residues in rice?

Choose regular, qualified and legally compliant pesticides that meet national standards, so that pesticide residues in rice can be effectively reduced. Pesticides that meet national standards are generally configured according to a certain safety factor, so when we choose to spray these pesticides, we can naturally reduce certain residues, after all, the production of pesticides now pays attention to high efficiency and low residues. For some shoddy quality or even some small manufacturers, there may be no strict implementation of the relevant national standards of the procedures, which will naturally lead to high residues, which will increase the pesticide residues in rice.

Do not increase this concentration by spraying pesticides, and configure pesticides according to the pesticide description standards, and then spray.

Calculate the safety cycle and don't spray pesticides when the harvest is about to be harvested. Pesticide spraying it also has a safety cycle, for example, spraying some pesticides, its safety cycle is about 10 days, then we should not spray pesticides when we are about to harvest, even if we want to spray pesticides, then we have to wait until 10 days later to harvest, so that the pesticide residues in the rice will be more or less volatilized, almost to ensure the food safety of rice. <>

Don't sprinkle pesticides as soon as there is a problem, and try not to use pesticides if you can. The less pesticides are used, the less pesticide residues will be on rice, for example, some pests can be treated by cultivating natural enemies, so do not spray pesticides. Like some red spiders, then we can cultivate some seven-star ladybugs to kill, then we don't need to sprinkle pesticides.

Choose biopesticides to control some pests and diseases. Biological pesticides are generally high-efficiency, low-toxicity and non-residue-free, so the use of these pesticides for prevention and control can naturally reduce pesticide residues in rice. We have a lot of growers who grow rice for their own consumption, and they use biopesticides, including vegetables, even if there are insects, they also use biopesticides, after all, there will be no residue and it will be healthier.

When choosing pesticides, we must choose some pesticides that are compliant and qualified, and choose pesticides with low toxicity and high efficiency. In fact, when many people choose pesticides, he doesn't care whether you are low toxicity or high toxicity, there is no clear distinction, so it is easy to lead to pesticide residues in rice, we must choose some low-toxicity and efficient pesticides when choosing pesticides, so that it can play a good role in avoiding pesticide residues. <>

The selection of pesticides must be complete with three certificates, and it is necessary to see whether its label has this certificate. Qualified pesticides are often highly efficient and low toxicity, and unqualified pesticides and pesticides of poor quality often have high toxicity and high residues. Although some fake pesticides can also play a killing effect, but it will lead to excessive residues, which will affect the amount of pesticide residues in rice, and then the detection will not endanger food safety, so when choosing pesticides, you must buy them through regular channels, do not buy them from some small traders and hawkers, and it is easy to buy shoddy or even counterfeit pesticides.

Do not increase this dose when spraying pesticides, as this will cause high residues. There will always be some people who make their own clever efforts to increase the concentration of pesticides for disease prevention, or kill some insects, in fact, such a method can not increase the effect of killing insects, but will easily cause pesticide damage or cause high residues, but will affect the health of people who eat it. The increase in concentration will not necessarily strengthen the insecticide but will lead to the waste of pesticides, after all, pesticides are not cheap now, do not increase the concentration casually.

If conditions permit, it is best to choose some biological pesticides, because biological pesticides are basically pollution-free and residue-free, but the cost is slightly more expensive. Nowadays, many people eat vegetables and fruits, as well as some rice, and they pay attention to food safety, so if they can use this biological pesticide, then try to use biological pesticides. After all, biopesticides do not have high residues, and the safety cycle is shorter.

To reduce pesticide residues in rice, we must choose high-efficiency, low-toxicity and low-residue chemical pesticides; At the same time, do not use excessive pesticides, just in moderation; Choose new and efficient plant protection machinery and equipment; When there are pests and diseases, we must use drugs as soon as possible, so as not to spray a large number of pesticides at the end, which is not conducive to the volatilization of pesticides and affects the growth of rice.

Because we do agriculture, different crops will inevitably be sick and insects, we generally need to spray in order to solve the problem, if the pests and diseases are not serious, a little medicine can be used, if it is not easy to treat, it is generally necessary to spray more toxic or pesticide types to prevent and control, although many pesticides have a certain decomposition effect, but the dosage exceeds the standard or remains in the plant body or remains in the fruit.

Last year, a grape grower in Fujian Province said that because of pesticide residues, he threw away all 50 acres of grapes, and suffered heavy losses, and 10 acres because of the use of a biological fungus selenium-rich foliar fertilizer, grapes were less sick, although pesticides with residues were also used, but the test results were no pesticide residues, which avoided part of the loss.

Through this grower, biological control can not only reduce the occurrence of plant diseases, but also have a certain role in degrading pesticide residues, so after use, not only the quality and taste are better, but also the sales are more assured.

For reducing pesticide residues and using fewer pesticides, it is recommended to use biological control methods, so that plants are less sick, we can use less pesticides, and the fruits can be more assured!

How to reduce pesticide residues, mainly the following points:

1.Reduce the amount of pesticide used. How to reduce the number of pesticide applications, in a nutshell, is to create environmental conditions suitable for rice growth and unfavorable to pest and disease infection through agricultural measures, so as to improve disease (insect) resistance, reduce or inhibit the occurrence and harm of pests and diseases, and reduce the number of pesticide applications.

2.To talk about it three times, we must choose high-efficiency, low-toxicity, low-residue chemical pesticides. The agents for the prevention of rice blast include avi fluoramide, chlorantraniliprole, emamectin, avermectin, etc., the prevention and control of paddy field rice planthoppers can be selected with pymetrozine, dinotefuran, dinotefuran, etc., the prevention and control of rice rice koji disease can be prevented and controlled with azoxystrobin, difenoconazole propiconazole, hexaconazole and other agents, the pesticides available for the prevention and control of rice rice koji disease are tricyclazole, rice blast, chunleimycin, etc., and the prevention and control of rice sheath blight can choose thifluoramide, jinggangmycin, difenoconazole propiconazole and other agents.

Pesticides with complete "three certificates", safety, high efficiency, low toxicity, low residue and low lethality to natural enemies should be correctly diagnosed. <>

3.Prompt administration of medications**. By choosing the appropriate application time, not only can the number and frequency of medication be reduced, but also the prevention and control effect is greatly improved.

Spraying is usually carried out at the egg hatching stage or the young nymph stage, and the rice disease can be sprayed before or at the beginning of the disease. For example, rice koji disease can be sprayed to prevent 5-7 days before the breach, rice planthopper can be sprayed and controlled at the peak stage of young nymphs, ditropic can be sprayed at the egg hatching stage or young larval stage, and sheath blight can be sprayed and controlled at the larval stage. <>

4.Choose new and efficient plant protection machinery and equipment; Focus on the selection of new types of plant protection equipment such as powder sprayers, thermal fog machines, electrostatic sprayers, cyclones, electric sprayers, etc., to reduce the amount of pesticides and improve the utilization rate of pesticides.

5.Strictly control the amount and quantity of pesticides. The drug should be used in strict accordance with the pesticide label or instructions, the dosage and concentration of the drug should be strictly controlled, and the recommended dose of the pesticide should not be increased or decreased at will. The dosage should be strictly controlled, and the reasonable dosage interval should not exceed the maximum dosage indicated on the label.

In order to reduce residues, we can only choose some relatively safe and healthy pesticides, and in addition, pesticides can also be degraded by manually removing pesticides.

I think the best thing to do is to spray pesticides before it rains, so that the residual pesticides can be washed away after a rain.

If you want to reduce pesticide residues in rice, you should wash it with clean water, because it can wash away pesticides.

Create environmental conditions suitable for the growth of rice, but not conducive to the infection and onset of pests and diseases, and improve the disease resistance of rice, so as to reduce or inhibit the occurrence of pests and diseases, and reduce the number of pesticide applications.

After the rice is sprayed with pesticides, you can water more, and the rice pesticides should also be sprayed regularly, not too much at one time, so that the rice pesticide residues can be reduced.

It should be watered more so that the residue of the drug can be reduced. Then just rinse off these pesticides.

I think we must pay attention to the amount of pesticides used, and then we should also pay attention to the ratio of pesticides, and avoid using too many pesticides, so as to reduce pesticide residues.

When spraying the remaining pesticides, the use of pesticides should be scientific, and generally when spraying pesticides, it is also necessary to grasp the critical period, and it is best to choose some biological physical methods to prevent and control pests.

Reduce the number of pesticide spraying, and when the old defense disease is lacking in pests, we must choose pesticides with strong strength, and also choose the right time to spray. Some high-tech machinery can also be used to spray and control the frequency and dosage of pesticides.

To use it reasonably, to spray pesticides at critical moments, to master the correct spraying methods, to carry out comprehensive management, and to use organisms for insecticide.

Pesticide residues, especially after the use of pesticides in agriculture, some pesticides directly or indirectly remain on grains, fruits, vegetables, etc., attached to crops or scattered in the soil, water and atmospheric environment, pesticide use within a week after decomposition without residue in the organism, after harvest, trace pesticides in water, soil toxic metabolites, degradants and impurities. Different pesticides have different dosages, in the selection of pesticides, do not increase the dosage or increase the number of uses, which will not only cause pesticide waste, is the main pesticide residue of crops, so should be based on the prevention and control object, choose the right pesticide varieties, grasp the best time to use pesticides and pesticide use standards, so as to ensure the control effect and reduce pesticide residues.

It is necessary to select the corresponding pesticides, use pesticides in a timely manner, strictly control the concentration and frequency of use, and adopt a reasonable prescription for medication. It should be noted that pesticides of different products should be used in turn to prevent pests and diseases from developing resistance, and the safety interval of pesticide use should be strictly enforced. Due to the over-reliance on chemical pesticides to prevent and control plant diseases and pests of rice, especially the scientific behaviors of some farmers to increase the abuse of pesticide dosage, usurpation and reform and the random use of pesticides, the ability of rice to resist diseases and insect pests has risen, the control effect has declined, the environmental pollution is serious, and the environmental problems and safety problems such as reducing the utilization rate of pesticides and excessive pesticide residues have been reduced.

How to reduce pesticide residues and choose the right application time can not only reduce the dosage and use times, but also greatly improve the control effect. Rice pests are generally sprayed at the egg hatching stage or the young nymph stage, while rice diseases can be sprayed before or at the beginning of the disease. For example, rice whitefly disease can be sprayed 5-7 days before the rice break, rice planthopper can be sprayed at the flowering stage of young nymphs, dimorphic borer can be sprayed at the flowering stage of eggs or young larvae, and sheath blight can be sprayed at the early stage of disease.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

When spraying pesticides, it is necessary to choose pesticides with relatively small waxing properties, and must be produced by regular manufacturers, and the quality must be guaranteed, and the concentration should not be too high when spraying.

Strictly control the number of pesticides used, vertical flushing and dosage, select some high-efficiency and low-toxicity pesticides, choose some biological drugs, and choose different pesticides for replacement.

Reduce the pesticide spraying of rice, choose the quality of the lead is good, pay attention to the time of spraying pesticides, to use pesticides suitable for planting rice, only the high-tech spraying pesticide method.

Farmers plough the field and plant rice, if you do not spray pesticides, pests will harm rice seedlings, serious fruit particles are not harvested, pesticides are used, rice will be pesticide residues, the only way to reduce pesticide residues is to treat insects when the rice is not mature, and the prevention is mainly in the later stage.

Based on personal experience, I will give you a few effective ways to reduce pesticide residues in rice:

1. Reduce the accumulation of soil pests and diseases, clean the countryside, reasonable irrigation and fertilization, 2. When applying pesticides, select counterpart pesticides, use pesticides in a timely manner, strictly control the concentration and use times, and should adopt reasonable drug methods. It should be noted that pesticides in different products should be used in rotation to prevent pests and diseases from developing resistance, and the safe interval of pesticide use should be strictly implemented.

3. Different pesticides have different dosages, for the selected pesticides, do not increase the dosage or increase the number of uses, which will not only cause the waste of pesticides, but also produce pesticide damage, the main thing is to lead to crop pesticide residues, so according to the control object, select the appropriate pesticide varieties, grasp the best time to use pesticides and pesticide use standards, so as to ensure the control effect and reduce pesticide residues.

4. It is best to use the prevention and control of diseases in the early stage of the disease, because at this time the larvae are concentrated, the resistance is relatively weak, and the application is the most appropriate. There is also a need to pay attention to the safety room, that is, the time between the last use of pesticides and the harvest time, and the use of pesticides should be stopped during this time period to prevent excessive pesticide residues.

5. To choose high-efficiency and low-toxicity residual pesticides, the use of high-additive, high-efficiency residual pesticides should be avoided. It is also necessary to use alternate medications. If a pesticide is often applied, not only the drug properties are poor, but also easy to lead to pests and diseases to develop resistance to the drug, so the pesticide with different mechanisms of action should be used alternately, which can not only avoid the occurrence of resistance to peace, but also can effectively reduce pesticide residues.
