Is there any harm in often being with pesticides and fertilizers?

Generally speaking, the mixed use of fertilizers and pesticides is at most a mixture between foliar fertilizers and pesticides. Pay attention to the following contraindications when using:

Alkaline pesticides (Bordeaux liquid, pine resin mixture, stone sulfur mixture) cannot be mixed with ammonium nitrogen fertilizer, superphosphate, etc., otherwise it will cause ammonia volatilization loss and reduce fertilizer efficiency;

Arsenic-containing pesticides should not be mixed with potassium salt and sodium salt fertilizers, otherwise soluble arsenic will be produced, resulting in crop pesticide damage;

Alkaline fertilizers such as ammonia, plant ash, and lime cannot be mixed with pesticides such as sulfacarb, tobuzin, jinggangmycin, leafhopper powder, carbendazim, and pyrethroid insecticides, because organophosphorus pesticides generally decompose under alkaline conditions;

Fertilizers should not be mixed with microbial pesticides. Fertilizers are mostly volatile and corrosive. When they are mixed with microbial pesticides such as bacillus and green worm fungus, it is easy to kill microorganisms and reduce the control effect.

In addition, when foliar fertilizer and pesticide are mixed, it is necessary to pay attention to the mixing order, usually: foliar fertilizer, wettable powder, suspension agent, water agent, and emulsifiable concentrate are added in turn, and then the next one is added after full stirring and mixing.

If it is mild, it may cause cancer if it is not good luck for a long time.

Yes. If you are not careful, you will leak or accidentally eat it. Buy a big insurance.

The harm is a little bit, but it doesn't matter. Don't be nervous.

1.Pros and cons of fertilizers.

Benefits: high content of nutrients, fast and significant fertilizer efficiency, a wide range of raw materials, can be mass-produced, beneficial and used.

Disadvantages: The nutrients are relatively simple, the cost is high, and the soil, water and air are polluted.

2.Pros and cons of pesticides.

Pros: Different types, different functions. The benefits of pesticide use can reduce the amount of labor and increase or maintain yields in both positive and negative ways.

Disadvantages: At the same time of using pesticides, firstly, the soil structure is damaged, resulting in soil pollution that is not conducive to crop growth; Second, polluting water resources. third, to make pests and diseases resistant and reduce the effect of pesticides; Fourth, because pesticides are not degraded or are difficult to degrade, they will accumulate in organisms at a relatively high level of the biological chain, and human health is threatened.

3.Rational use of chemical fertilizers and pesticides.

China has a large population and little arable land, and chemical fertilizers and pesticides are still the elements of agricultural development.

Provide a few aspects separately to say:

Chemical fertilizers can lead to soil compaction, salinization of the soil. That is, it leads to poor soil. Since there is a debate competition, they will definitely say that chemical fertilizers will increase production or something, don't be afraid, without chemical fertilizers will not necessarily reduce production, and there are several chemical fertilizers that are extracted from ores, which are non-renewable resources, and there is a lot to say about this.

Speaking of pesticides, this is more:

1.Pesticide residues can affect human health.

2.Pesticides can disrupt the ecological balance, because pesticides do not distinguish between pests and beneficial insects.

3.Pesticides and fertilizers will pollute the environment, such as polluting water bodies, polluting the air, etc., this kind of debate will not be lost, and those who say that fertilizers and pesticides can also say that they can win in this environment can go to the World Debate Championship.

Chemical fertilizer is a kind of fertilizer, and pesticides are completely different agricultural products.

Fertilizers and pesticides have a common characteristic, that is, if used incorrectly, they can cause harm. However, the hazards are also different, chemical fertilizers are mainly composed of various salt substances and nutrients. Therefore, when we grow crops, we use a lot of chemical fertilizers containing a lot of salt substances for a long time.

When the chemical fertilizer enters the soil, it will lead to an increase in the concentration of the soil solution, resulting in uneven osmotic pressure in the soil. The harm of pesticides will directly act on the environment, causing serious pollution to the environment. And there is also the possibility of indirect harm to the human body through the ecological cycle.

According to the speed of effect of chemical fertilizer, there are categories of fast-acting fertilizer, slow-acting fertilizer and long-acting fertilizer. In the case of pesticides, they are first divided into insecticides, fungicides, and herbicides according to germs, pests, and weeds. There are also pesticides to control rodent infestation, and if they are used to regulate the growth of crops, they are also classified as plant growth regulators.

The effect of chemical fertilizers and pesticides on crops is completely absent, and chemical fertilizers are used as a kind of fertilizer. Pesticides, on the other hand, are mainly used to prevent crop diseases, and they also have the effect of regulating plant growth.

What are the functions of pesticides and fertilizers? What will be the impact?

FertilizersIt is the necessities of crops, and chemical fertilizer is the first choice of many crops, reasonable application of chemical fertilizer has the effect of increasing crop yield, but if excessive application of chemical fertilizer, it will be counterproductive, not only harmful to crops but also dangerous soil. Therefore, our country advocates soil testing and fertilization, and how much is lacking, because excessive fertilization is really harmful and unhelpful, thenWhat are the dangers of using too much fertilizer?

The harm of pesticides to us

The largest pesticide used in China is organic synthetic pesticides, pesticides in the benefit to human beings at the same time also caused harm, endangered human and animal health, killed other beneficial organisms, polluted soil, waters, destroyed the ecological "food chain", disrupted the ecological balance, this called "explicit harm" or "exposure hazard" impact can attract people's attention. The other type of pesticides is called "hidden hazards" or "potential hazards", which cannot be shown in a short period of time, and it takes a long time for people to begin to notice and experience.

In general, pesticide residues in plants are plants grown in soil, and with the growth and maturity process of plants, pesticides directly enter the roots and leaves of plants, and pesticides can be left in agricultural products.

There is also a kind of pesticide residue that adheres to the surface of vegetables and fruits, some of which can be biodegraded into harmless substances in a short period of time, while some pesticides are difficult to degrade and are pesticides with strong residues. The bioenrichment of pesticides is the most serious form of pesticide indirect harm to organisms, pesticides in plants can be passed through the food chain and continue to accumulate, long-term contact or consumption of food containing pesticide residues, can make pesticides accumulate in the body, the biggest potential harm to health is chronic poisoning and "three causes" effect.

The harm of chemical fertilizers to us

Fertilizers play an extremely important role in increasing crop yields. Moreover, over-reliance on the application of chemical fertilizers not only causes waste, but also brings a lot of chemical pollution to people's lives. The substances that pollute the soil by chemical fertilizers are heavy metals and radioactive substances, mainly in the raw materials used in the manufacture of chemical fertilizers.

The heavy metals that produce pollution mainly include cadmium, nickel, cobalt, zinc, copper, etc., once the soil is polluted by heavy metals, it is difficult to completely eliminate, not only can not be biodegraded after entering the soil, but can be continuously enriched in plants and organisms through the food chain, and can even be converted into more toxic methyl compounds.

With the action of chemical fertilizers, pesticides, and other chemical synthetic substances in agricultural production, agricultural production capacity can be greatly improved, increase the output of agricultural products, and bring more income to farmers, but excessive use of chemical fertilizers and pesticides will not only cause food safety problems, but also pollute the land to varying degrees. The irrational use of pesticides and fertilizers has led to the intensification of pollution of agricultural farmland, and the use of chemical fertilizers and pesticides in China's agriculture accounts for more than 30 of the global total, and the utilization rate is too low, resulting in soil acidification, salinization and compaction of the land resulting in a decline in soil fertility, heavy metals, nitrates, and other harmful substances polluting the soil, and even water and air, and finally destroying the ecological environment at the same time, it will also lead to a decline in the quality of agricultural products.

The reason is: first look at the main crop wheat fertilization, mainly basal fertilizer and top dressing, foliar spraying. The time is in the sowing period, the drug is divided, and the foliar spray is mainly in the late stage of wheat growth.

Weeding is done at the 3rd to 5th leaf stage of wheat and before jointing. So, the seasons can't be mixed together. And some pesticides mixed with chemical fertilizers will cause pesticide damage to wheat.

It is not recommended to use them together. Looking at corn again, fertilization should be deeper at the sowing stage, while sealing with herbicides should be applied to the soil surface. After emergence, herbicides should be applied at the 3rd to 6th leaf stage of corn seedlings.

Otherwise, it will cause drug damage. At this time, because the seedlings are small, they are generally not topdressed. Therefore, corn is also not usable.

From this, we can also see that general crops should not be used together.

Pesticides and fertilizers are unrelated and unaffected. Pesticides are generally applied to the surface of grass, while fertilizers are mostly applied underneath the soil layer. Generally, in addition to spraying on weeds, pesticides generally have the effect of sealing the soil surface.

So it's best to fertilize first and then spray pesticides. Pesticides break the original soil ecological balance, while killing pests, some beneficial bacteria in the soil are destroyed, the soil is forcibly cultivated every year, and the soil fertility is restored without the fallow period, and chemical fertilizers are used to improve, but the use of chemical fertilizers is only a fast medicine and can not be fundamentally alleviated, so there will be some farmers who take turns to cultivate every year when planting, not always planting corn or something, so that the soil has a recovery period, so we must adapt measures to local conditions every time we use chemical fertilizers or pesticides. The use of chemical fertilizers will harden the soil, and pesticides will aggravate the pesticide residues of agricultural products, affecting the health of customers. It can make farmhouse fertilizer, do not use pesticides, promote ecological recycling agriculture, natural farming, grow good crops, and have healthy agricultural products with zero pesticide residues!

When put together, it is easy to decompose and fail pesticides, corrode pesticide packaging, and bring unnecessary trouble to the use of pesticides. Acidic fertilizers such as superphosphate will volatilize free acid during storage, making the humid air in the warehouse acidic, and most pesticide packaging is easy to be corroded and damaged in an acidic environment. It can also cause a combustion** accident.

Because these two are different agricultural products, they may have a chemical reaction when put together, which will affect the crops very much, so they cannot be put together.

If the two are placed in a warehouse, due to the change of cold and warm temperature, it will cause chemical reactions, and the fertilizer will be ineffective; In severe cases, it can cause ** or poisoning.

Doing so can lead to chemical reactions that can cause serious damage to the plant and affect the effects of fertilizers and pesticides.

Because if two things are put together, it is particularly easy to **, and it is also easy to have a chemical reaction, resulting in poisoning.

Many of our farmers have this question, we often need to spray foliar fertilizer or fertilization, can we mix pesticides or plant growth regulators with chemical fertilizers? This not only reduces our labor intensity, but also reduces the planting cost to a certain extent, isn't it a double win? So what should we pay attention to when mixing chemical fertilizers and pesticides?

What's in it for you?

First, it can improve the medicinal power, for example, the urea solution we add to the 2-4d acetate can reasonably improve the digestion and absorption efficiency of the medicinal power, and then improve the actual effect of herbicide.

Second, the fertility can be improved, such as the mixture of prometrinet and basal fertilizer, which can reasonably improve the utilization efficiency of basal fertilizer.

Third, improve the effect, for example, in the case of topdressing and returning to green fertilizer in rice fields, adding pesticides to hoe can slow down our labor efficiency and improve work efficiency.

Even though there are so many benefits of mixing chemical fertilizers and pesticides, can we mix pesticides freely? Naturally, it is not good, and we should pay attention to some problems when mixing chemical fertilizers and pesticides.

The first problem is the problem of acid-base neutralization, that is, the first standard for us to mix chemical fertilizers and pesticides is not to harm the actual effect of chemical fertilizers or pesticides. For example, ammonium nitrogen and water-soluble phosphorus and potassium fertilizers cannot be mixed with alkaline pesticides such as agricultural streptomycin.

The second question is Wu Chong, if there is no harm to food crops after mixing, we must find out whether the chemical fertilizers and pesticides we mix will cause harm to food crops after mixing? This must be clarified.

The mixing of pesticides and fertilizers with different preparations is also emphasized, so let's talk about it. If our pesticides and fertilizers are all solid, we can mix them together and immediately apply them to the soil layer; If it is a wettable powder, we need to apply the surface layer of the fertilizer with tap water first, and then stir it evenly; If it is a liquid or emulsifiable concentrate, we can pour it directly on the fertilizer and mix it. If it's too wet, we can also add some fine sandy soil to mix.

When we mix pesticides and chemical fertilizers, we need to figure out a question, that is, do we want to use chemical fertilizers as modifiers or do we want chemical fertilizers and pesticides to be used together? Since chemical fertilizers can also be used as modifiers, the urea solution we mentioned earlier can be added to pesticides to improve the potency of pesticides. In the case of the use of chemical fertilizers as modifiers, we need to be careful to manipulate the amount used, which may harm food crops.

To put it simply, it is necessary to distinguish priorities and grasp the amount of chemical fertilizers and pesticides mixed. There are also basic common sense, such as whether the herbicide for leaf topdressing can not be applied in soil. Okay, that's all there is to share!

Do you think what I'm talking about works?
