Is it a habit for farmers to use pesticides? Are pesticides harmful?

In rural areas, farmers have indeed formed a habit of using pesticides, and the harm of pesticides is very great, which will bring pesticide ingredients to food, which will bring harm to human health. However, with the continuous improvement of the scientific and technological level of agriculture, many modern agricultural products are more extensive, and the planting technology has also been promoted. Nowadays, there are many agricultural products, and specialized fertilizer varieties as well as pesticides can be used.

In the process of modern agricultural tools, pesticides can save a lot of manpower and material resources, and can also liberate the non-agricultural industry. <>

In general, the harm of pesticides to the human body is mainly manifested in acute poisoning, chronic diseases and various hazards of ** diseases. Acute poisoning is caused by respiratory exposure to large amounts of drug toxins, resulting in nerve paralysis. If it causes a large area, it may also cause death, which is obviously the harm that pesticides bring to the body.

Long-term exposure to pesticide residues in the diet is constantly accumulating in the human body, which also poses a threat to health. It affects the nervous system of humans and can also disrupt the function of the liver, causing disorders in the reproductive system. <>

For women who often eat vegetables and fruits during pregnancy, if there are pesticide residues on them, it will lead to fetal malformations. Some can even cause cancer, and not only that, but the nature of pesticides can also affect soil hazards. As the pollution level continues to increase, the crevice density of the soil will gradually decrease, which will cause the soil mechanism to compaction.

What grows in this way has no nutrients, does not produce what the farmer wants, and has a serious impact on soil organisms. <>

Although pesticides can kill pests, the remaining microorganisms will also affect different degrees of harm. In particular, the impact of pregnant women, children and the elderly is the most obvious, and now farmers are also aware of and personally feel the harm caused by the use of chemical fertilizers and pesticides to their lives, which has caused inevitable losses and is very difficult to repair. It also calls on farmers from all walks of life to use pesticide products carefully, find the right way to sow seeds, and make progress together with the pace of scientific and technological development of the times.

It is a habit, and the harm of pesticides is not too great, because pesticides can effectively promote the growth of crops, as long as the crops are cleaned, they will not cause harm.

It has become a habit to better restrain some natural problems in the soil in this way. However, the use of pesticides may lead to the occurrence of diseases. It may cause cancer.

This is indeed the case, because farmers believe that pesticides need to be applied as soon as pests appear; The harm of pesticides is still very large.

It is indeed like this, and the harm of pesticides is also relatively large, so be sure to wash vegetables and fruits before eating.

The advantage is that it can improve the growth rate of crops, and it can also kill some diseases and insects on the surface, but the disadvantage is that after using it for a long time, it will cause great damage to the roots.

Affect the quality and yield of agricultural products, will damage the soil structure, may not achieve the effect of pest control, so we must use chemical fertilizers and pesticides reasonably.

There are many drawbacks, first of all, it will damage the ecosystem, it may also destroy the surrounding organisms, and then it is also likely to cause the acidity and alkalinity of the soil to be destroyed.

The use of pesticides in agricultural production activities can prevent pests and diseases and reduce the damage of pests and diseases to plants, but pesticide residues may be harmful to humans. And it will contaminate the soil.

The effects of pesticide spraying on crops mainly include residual hazards, chronic hazards, and acute hazards. Crops are our daily food**, how should we reduce the impact of pesticides on them? Let me answer you in detail.

First, the specific meaning of pesticides causing various harms to crops.

First of all, the specific meaning of residual hazard is that when we spray pesticides on crops, some pesticides will be directly left on crops and then harm crops. Then the specific meaning of chronic hazards is that the impact of pesticides on crops is not immediately reflected, this hazard is not easy to observe, and it is easy to be confused with the physiological diseases of the crops themselves. Finally, the specific meaning of acute hazard is that the harm of pesticides to crops can be immediately reflected, and the main symptoms are spots, perforations and burning.

Second, how to reduce the adverse effects of pesticides on crops.

The main ways to reduce the impact of pesticides on crops are as follows. First of all, we must use pesticides rationally in accordance with the requirements of the state, and we cannot use pesticides at will based on our own subjective feelings. Then we have to alternate the use of drugs to control pests and diseases, and develop resistance to pesticides.

When pests and diseases become resistant, many people will directly increase the amount of pesticides, but this is not only useless, but also has a very bad impact on crops and the environment. Finally, we should also pay attention to the right medicine, according to the pests and diseases to choose pesticides, many people in life will be because of the good effect of a pesticide has been using that kind of pesticide, without considering the transfer of pesticides, this is actually a very bad behavior.

Third, how should we reduce the harm of pesticides to ourselves in our daily life.

Crops are the food we eat every day**, and how should we ensure our own food security when it has been seriously infested with pesticides.

This. First of all, we must wash vegetables and fruits when we eat them, and then we can try to choose to buy ecological vegetables that are not sprayed with pesticides.

I hope that through my ability, I can help you better understand how to reduce the impact of pesticides on crops.

Acute drug injury. After spraying for hours or days, the crop will show noticeable symptoms. For example, crop leaves are white, yellow, and have different problems such as spots, perforations, curls, cokes, sagging, wilting, and falling off.

In general, this drug damage is a phenomenon caused by improper use of drugs in humans. Chronic drug damage: After spraying chronic drug damage, the current drug damage is not obvious.

After a period of crop growth, it is found that the crop growth and development is poor, slow, short or weak. For example, if we spray drugs to inhibit the growth of crops, if the dose is too large, it will cause drug damage, and the growth of the plants will be stagnant and jointed, and they will only grow thicker, and the leaves will not be elongated and thicker.

This kind of drug damage mostly occurs in the problem of reasonable changes in drug efficacy caused by excessive pesticide dosage or unreasonable proportion, and in the United States, drug harm is related to crops. For example, some crops are sensitive to certain copper sulfate drugs, and some crops are sensitive to calcium arsenate and cannot be absorbed; 2.Drug damage is related to the spraying environment.

This is related to problems such as temperature and humidity, such as low temperature, high dew, spraying pesticides, crops can not be effectively absorbed, and drug residues on crop plants for too long will cause drug damage. 3.Man-made drug injury.

For example, go to an informal place, buy fake pesticides, or mix pesticides to control pests and diseases, or complete a pesticide to control crop pests and diseases. It craves to use the drug again every once in a while.

Spraying pesticides can sometimes produce acute damage, chronic damage and pesticide residue damage, which can lead to wilting, stunted growth, and weakened photosynthesis, resulting in reduced crop yields.

If pesticides are sprayed too much, the residual pesticides will accumulate in the food chain, and the species at the top of the food chain will be most harmful (generally to people). Long-term spraying of pesticides can disrupt the ecological balance.

Spraying pesticides can reduce the occurrence of pests and diseases in crops, but to a certain extent, spraying pesticides will also cause other diseases in crops, so that the quality of crops will decline, and the yield will decrease; In order to reduce this effect, it is necessary to choose the right pesticide for spraying, and when spraying, it should be in a certain proportion, and the crops should be watered on time after spraying.

Spraying pesticides will produce pesticide residues on crops, in order to reduce this impact, you can not use drugs indiscriminately, you should use drugs reasonably and correctly, and you should choose suitable drugs according to the diseases and pests of crops.

It will have a great impact on crops, it will affect the development of crops, it will affect the yield of crops, and it will also affect the growth. In normal times, attention should be paid to the amount of pesticides sprayed and the proportion of pesticides.

The correct use of pesticides can effectively prevent and control crop diseases, insects, weeds and rodents, ensure a bumper crop yield, obtain the greatest economic benefits, protect the ecological environment, and ensure the quality and safety of agricultural products. The abuse of pesticides may lead to increased resistance to diseases, insects, weeds and rodents, increase the difficulty of prevention and control, and may also cause potential safety hazards in agricultural products, such as excessive pesticide residues in agricultural products, resulting in the deterioration of the ecological environment and affecting the normal life of human beings.

Proper use of pesticides:

1.Correct use of pesticides can minimize the harm of pesticides to oneself.

2.Proper use of pesticides can reduce the spread of pesticides and avoid the lethality of surrounding crops.

3.Correct use of pesticides can reduce the rate of degradation of pesticides themselves.

4.The correct use of pesticides can effectively control pests and diseases and improve crop yields.

Misuse of pesticides:1It leads to the emergence of drug resistance, shortens the service life of the product, leads to the continuous increase of the dosage, and causes a vicious circle that leads to excessive residues in agricultural products.

2.It has direct or indirect poisoning to insects (beneficial insects), fish, bees, and birds, destroying the ecological balance and affecting human health.

3.Misuse leads to drug damage, loss of crop production, environmental watering, air pollution, etc.

Pollute the environment and kill any living thing.
