Is it better to plant land by hand or with herbicides?

It is better to manually weed than to use herbicides, after all, herbicides have certain damage to the soil, and if you plant the land in the future, it may affect the growth of crops.

Farming is the implementation of harmless production and green food, and it is of course good for talents to weed. However, the intensive management of agricultural production, advocating agricultural production machinery field operations, only satisfied with manual weeding is certainly not able to swing the conditions of full production, a weed will regenerate after weeding, so in order to produce the needs and more able to increase production and income, it is necessary to study non-toxic and harmless herbicides, so that it is the need for the development of science and technology.

Of course, manual weeding is better than herbicide. Because herbicide weeding will cause harm to the land, after all, the chemical products tested by herbicides will pollute the soil of the land, and manual weeding may cost some manpower and labor, and there is no harm to anything else, which is more environmentally friendly.

From the point of view of environmental protection, of course, it is good to plant land by manual weeding, and it is easy to harm the land with herbicides, but the problem is that if the land area is too large, relying on manual weeding, now the labor cost is very high, and it is generally unaffordable, so you can only use herbicides, which is no way to do it.

Although the herbicide weeding is more efficient, it will cause some harm and pollution to the soil crops, so manual weeding is better, but the efficiency is relatively low and it is hard.

Farming is definitely the best for manual weeding. Manual weeding is the most environmentally friendly.

In this way, there is no other harm to crops, and there is no impact on human health.

If herbicides are used to control weeds, there are a lot of chemical components in them. It has a lot to do with the impact on crops and human health.

Planting should be done manually, weeding, although tired, hard, but manual weeding will not cause harm to seedlings and will not have pesticide residues herbicides. It is too powerful and is easy to damage the seedlings.

Farming is definitely the best for manual weeding. Manual weeding does not harm the soil, and manual weeding allows plants to grow more lushly.

Planting must be manual weeding is more suitable, the use of herbicides will also kill the vegetables, although manual weeding is harder, but this method is the best.

Although herbicides are highly effective, the harm they bring to the environment is immeasurable, and a large number of pesticides remain in the soil, which ultimately endangers us human beings. However, this can be completely avoided by manpower, and the environment can be better protected for the next generation of crops.

Even if it is a large area of land, artificial weeding is good, that is, it does not hurt the land and is environmentally friendly, but the surface is too large to remove, so I think the herbicide weeding is good, it is developed by scientific methods will not have a greater impact on the land and the environment, and save labor, time and energy.

Of course, manual weeding is better, but the cost of manual weeding is too high, the efficiency is low, and the effect of manual weeding of some weeds is not good. Herbicides have low cost, high efficiency and low input, but they can easily lead to soil compaction, which has a certain impact and harm to crops.

Hello: manual weeding should be better, because the use of herbicides, although the efficiency is high, but also faster, but it is harmful to the growth of crops, and manual weeding is slow, but more thorough, for crops are also good!

Therefore, it is better to manually weed in the end! Hope it helps, hope, thank you!

Manual weeding is good! Manual weeding is time-consuming and labor-intensive, but it does not cause pesticide damage! Using herbicides to control weeds saves time and effort, but there are also many harms, for example, if you use the wrong or accidentally spray on the crop, it will cause great harm; There may be drug residues; Wait a minute.

It is our environment that human beings depend on for their survival. Although herbicides are convenient, they bring about the deterioration of the soil environment, and more toxic chemicals slowly flow into our drinking water through groundwater, and these hazards are obvious. Respect for the earth, respect for life, green environmental protection, start with manual weeding.

It is better to plant the land or weed manually, and the removal is more thorough and clean.

Of course, manual weeding is good.

The parents still have the land, the grass growing in the ground is very tenacious, usually the herbicide is only the surface of the grass is gone, the grass roots are still falling, and the grass in the field has been resurrected not long after a few rains, and the artificial weeding is more curative.

Some crops have poor pesticide resistance, and it is easy to burn crops with too many herbicides, and manual weeding is safe, which avoids this shortcoming.

The herbicide may not be useful for all the grass after being sprayed several times, manual weeding can be seen more carefully, and the weeds in the field can be pulled out at one time, so that there is no need to worry about grass for a long time.

For crops, manual weeding is the best medicine. Manual weeding does not hurt the crops, and it is also meticulous in place. Therefore, when manual weeding can be done, try not to use herbicides to control weeds, so as not to affect the normal growth of the next crop due to improper application.

Farming must be good for manual weeding, which does not need to be sprinkled with chemicals in the process of weeding. Land is easier to grow and restore. There is also no alkalizing of the land. It's just that the efficiency of manual weeding is relatively slow.

Manual weeding is better.

On the one hand, manual weeding can remove the grass on the one hand, and on the other hand, it is equivalent to turning the ground over, so that the crops will grow better. However, pesticide weeding may not be able to completely remove the grass, and some places that have not been sprayed are still not possible.

However, the lack of manual weeding is that it takes manpower, energy, and time. Herbicides are relatively convenient.

However, manual weeding is still more effective and in the long run.

For the land, it must be better to weed by hand. Manual weeding, the removed grass rots in the ground, and the nutrients can be refreshed back into the ground. Herbicides have pesticide residues and are harmful to the ground.

For farming, manual weeding is better than herbicides, because manual weeding can turn over the soil without harming crops, which is conducive to crop growth.

Of course, planting is manual, and weeding is better, because manual weeding is greener. It will not destroy the seedlings and the herbicide hoe is particularly clean, it contains a lot of damage to the body. So it's best not to use herbicides.

Artificial roughness is definitely better than herbicides, herbicides are chemicals, harmful to grass and ground, especially to the soil is very harmful, Handan causes pollution to the air, and causes harm to weeding workers.

Herbicides are chemical products, and they are very harmful to the land. It's just that the herbicide is fast, and manual weeding is very slow, and it is easy to recur.

In the case of herbicides, it also has a certain chemical composition, and artificial weeding is natural and harmless. If you use herbicides to control weeds, pets will not be able to walk on it, which will affect them, and it is also easy to cause **allergies. After manual weeding, you can still smell the faint smell of grass on it.

Of course, planting is manual weeding, which is better than herbicide weeding, because herbicide weeding will cause harm to the land, after all, the chemical products tested by herbicides will pollute the land and soil, and manual weeding may cost some manpower and labor, and there is no harm to anything else, which is more environmentally friendly.

Herbicides have been applied to the ground.

The crops that can also be planted depend on the specific herbicide.

Broadleaf weed herbicides can also be used to grow grasses.

Crop; Grasses weed herbicides can also be used to grow grasses.

Such as beating the weeds to go to the gold.

Herbicide, which can be used to grow corn.

Atrazine herbicide can control a variety of annual grasses and broadleaf weeds. It is suitable for corn, sorghum, sugarcane, fruit trees, nurseries, woodlands and other dryland crops to control horsetail.

Barnyard grass, dog's tail base envy grass.

Sedges, kanmai niang, knotweed, quinoa, leguminous weeds.

How to use:1The use of corn field summer corn is used before emergence after sowing, and the soil organic matter quality is 1% to 2% in North China, Shandong and other places, 150 to 200 grams of 50% wettable powder per mu, or 175 to 200 ml of 40% suspension agent; Northeast China where the soil organic matter content is greater than 3% to 6%.

200 to 250 grams of 50% wettable powder per mu, or 200 to 250 grams of 40% suspension agent, the lower limit for sandy soil and the upper limit for clay soil. 1 to 3 days after sowing, spray the soil surface evenly on 30 kg of water. After the emergence of corn, the appropriate period is the 4-leaf stage of corn and the 2-3-leaf stage of weeds; For sandy soils with low organic matter content, use 200 to 250 grams of 50% wettable powder or 40% suspension agent per mu.

Spray on 30 to 50 kg of water. Spring corn per mu with 40% suspension agent 200 to 250 ml, add 30 to 50 kg of water, spray the soil surface before seedlings after sowing, mix soil after spring drought medicine, or appropriate amount of irrigation. Or in the 4-leaf stage of corn as stem and leaf treatment.

Corn and winter wheat.

In the continuous cropping area, in order to reduce or eliminate the pesticide damage of atrazine to wheat, atrazine can be reduced and mixed with herbicides such as grass jingjin, lasso, dol, 2,4 to d butyl ester, bandi farmer and green melon.

2.5 to 7 days after the cane is planted, the weeds are partially unearthed, 200 to 250 grams of 50% wettable powder or 40% suspension agent per mu, 30 kg of water is added, and the surface is evenly sprayed.

3.Tea gardens, orchards, vineyards use the peak period of weed germination in the field from April to May, first remove the unearthed grass and overwintering miscellaneous strokes, and then use 250 to 300 grams of 40% suspension agent per mu to evenly spray 40 kg of water on the soil surface.

Atrazine is a herbicide for pre-bud soil treatment, and can also be treated with stems and leaves after budding. Drought has a great impact on the efficacy of the medicine, and it mainly acts on dicots.

Focusing on closure, the effect on grass is not ideal. It also has a certain inhibitory effect on some perennial weeds.

The residue period of atrazine in the soil is generally about 6 months, because its residue period is relatively long, so it needs to wait for a period of time after application to plant the next crop, for cucumbers, it generally takes about 40 months to plant, and tobacco, alfalfa, sugar beet, rape, flax and other crops also need to go through 24 months before planting.

Summary. Seedling wilting can be caused by pests or diseases or herbicides. After herbicide application, seedling wilting may be a pesticide invention. It can be caused by uneven herbicide spraying or too much concentration.

Hello dear, it is best to plant after half a month. It's fine, different varieties of herbicide residue have different residues. After the weeds have withered, crops can be planted.

Depending on what herbicide is used, the residue period of different herbicides may be different. Because glyphosate can be decomposed by soil when it comes into contact with soil, crops can be planted in 8 to 15 days. Sowing can be done five to seven days after the application of pre-emergence herbicides.

Demolition of megans. Hello dear, can you type and say, I can't hear you well here.

I planted the weeding pesticide "Efficient Flupyromethalin" in the field and sowed the seeds, what is the matter with the seedlings dying now.

Seedling wilting may be caused by pests, diseases or herbicides. After the herbicide is applied, the seedlings wilt may be a pesticide damage. It may be caused by poor herbicide spraying or too large concentration.

This is best remedied with PTZ spraying.

Can it be saved? Is it serious, can I take a look.

It's very serious, I didn't shoot **, but some of them died, and some of the seedlings were yellow.

The leaves are all yellow.

What is dead cannot be remedied, but what is yellow can be remedied.

Now there is a field that has also been sprayed with this herbicide, and it can produce seeds every week before and after.

It is best to pro in 15 days, so that there is no drug harm at all.

In general, it takes 3 to 5 days after spraying herbicides, but if it rains, it can be shortened to 2 days. But there is no single answer, as follows:

The first thing to see is what kind of vegetables are planted and whether they are resistant to herbicides; The second depends on the concentration of the herbicide used. The above two conditions are the main conditions that determine how long after the herbicide is used before you can grow vegetables.

Herbicide refers to a type of substance that can completely or selectively cause weeds to wither and die, also known as herbicides, to destroy or inhibit plants that humans do not want to grow. Among them, sodium chlorate, borax, arsenic, trichloroacetic acid and other agents have a dead effect on any kind of plants, and their effects are affected by three main factors: herbicide concentration, plant and environmental conditions (soil, air, climate).

According to the function, it is divided into incidal and selective herbicides, and selective herbicides, especially nitrophenol, chlorophenol, and carbamate derivatives, are effective for most plants. The contemporary era is developing rapidly, and the styles of herbicides are also emerging in an endless stream, and what kind of herbicides to use depends on the soil conditions and the type of crops to be planted.

Generally, herbicides will be applied once before emergence, and different chemical herbicides should be selected after emergence according to the different seedling conditions of crops and different crops.
