What herbicide can be used to remove spiny cabbage?

Spiny herbs can be removed with glyphosate, which is generally effective and is often used by farmers.

The use of herbicides causes great harm to the ecology and the environment, it is not recommended to use herbicides, and the roots can be dug out with a shovel, which is more thorough.

It is another name for the perennial herbaceous plant of the Asteraceae family, the thistle, also known as green grass. Different herbicides should be used for spiny cabbage grown in different fields.

Use glyphosate and sodium dimethyltetrachloride to control weeds.

Summary. Spinach is a stubborn weed whose roots dig deep into the soil and are difficult to get rid of completely. However, the following chemical herbicides can be effective in controlling spiny greens:

1.Glyphosate: Glyphosate is a broad-spectrum herbicide that can reach the roots of plants by being absorbed by the leaves, killing the plants.

However, glyphosate may cause harm to surrounding plants. 2.Deltamethrin:

Deltamethrin is an agent that can be absorbed by the leaves to kill plants, including spiny spines. However, it can also cause harm to surrounding plants. 3.

Phenyl ether pill: Phenyl ether pill is also a broad-spectrum herbicide that kills the roots of spiny cabbage in the soil. However, it can cause damage to beneficial microorganisms in the soil.

Please note that chemical herbicides can cause negative environmental and health effects, so read and follow the directions on the label and take appropriate precautions before use.

There are crops in the field.

Summary. Commonly used prevention and control agents can be used to include dimethyltetrachloride sodium * zooxadone, dicamba, ethylcarboxoffen, dichloropyridic acid, chlorofluoropyroxyacetic acid, capryloyl bromobenzonitrile, and pyrcopine. The use of 2-methyl*azole oxazone, dicamba, and ethylcarboxyflufen is recommended.

Commonly used prevention and control agents can be used to include sodium dimethyltetrachloride * zooxadone, mai pure hail achlor, ethylcarboxyflufen, dichloropyridic acid, chlorofluoropyridine slag sailoxyacetic acid, octyropreacyl bromobenzonitrile, and pyropyrophyllace. The use of 2-methyl*azole oxazone, dicamba, and ethylcarboxyflufen is recommended.

Wheat field application B to tell carboxyfluorfen, it is best to use it before winter, the dosage can not be too large, the temperature is required to be above 10, otherwise it is easy to produce pesticide damage, causing wheat leaves to be bright and yellow, but it can generally be recovered after this thought. The drug has a fast action speed, high activity, and does not affect the next crop.

When is the best time to take medication?

Now this season is also possible.

What kind of medicine should be used for wheat *** in the future?

Ethylcarboxyfluorfen was applied to wheat fields.

This one. Isn't it harmful to hit the wheat?

That's right. Wheat field spiny cabbage, generally more than 5 leaves of wheat, choose to contain dimethyltetrachloroethylhexyl ester, zooxone, diazole chlorone and other agents for compound control, wheat durum beating is not safer?

Is it bad for corn stubble?

It doesn't hurt. Corn field thorn vegetable control, generally corn 5 leaves rise to cover stuffy, you can choose to contain nicosulfuron, dichloropyridine acid stuffy, if the choice of dichloropyridine acid stubble is not recommended to plant peanuts, sweet potatoes, soybeans noisy! It is not recommended to use one containing dimethyltetrachloride, which can easily lead to corn pesticide damage and lodging!

Thorn cabbage, also known as Qiqi sprouts, scientific name small thistle. Named because the leaf edge is covered with spikes, it is a very good Chinese herbal medicine (the hemostatic effect is particularly good), but it is a pity that it was born in the wrong place and ran into the farmland, and it became a stubborn weed that caused headaches.

As we all know, spiny cabbage is a well-known thorn head among weeds, and it is difficult to get rid of it with herbicides, so is there a herbicide that can effectively control spiny cabbage?

The answer is, there must be, if it is a spiny vegetable on the wasteland, it can be dried in a simple and crude way, such as glyphosate + dimethyltetrachloride combination, which kills weeds and removes roots, which is economical and affordable.

But it will take some trouble to treat the thorny vegetables that grow in the crops, just like a general who charges into battle with his family, not only to kill the enemy bravely, but also to protect his wife and children from being harmed, which is difficult, so the battle must be targeted and the grass must be targeted to remove.

The reason why spiny cabbage is difficult to prevent and control is that in addition to its tenacious vitality, it is also related to the development of its root system, such as glyphosate control, although it has the function of dead roots, but it is generally not completely dead, and after a period of time, it will be re-developed.

Therefore, when using glyphosate to control spinosa, it is recommended to add a packet of sodium compound nitrate or brassinolide to promote the activity of weed cells and make the effect effectively conducted.

Some crops can be dimethyltetrachloride, but to avoid cotton, okra and other crops sensitive to dimethyltetrachloride, due to the variety of crops, not listed here, you can consult local agricultural dealers.

In fact, there is also a herbicide, called dichloropyridic acid, which is also a product with special effects on spiny cabbage, the biggest defect of this herbicide is that the herbicide spectrum is narrow and the soil residue time is long, so it must be noted that it is very effective in killing Asteraceae and legumes.

Summary. Hello, dear, the herbicides generally used in spiny cabbage are, glyphosate, steady killing, and take the clean. It is better to use these herbicides, and the effect is relatively stable.

May I ask the teacher what herbicide is used for spiny vegetables, hello, dear, the herbicides generally used for stupid spiny vegetables are, glyphosate, steady killing, take the clean. It is better to use these herbicides, and the effect is relatively stable.

of cornfields. The corn is finished.

The ground was full of spiny vegetables.

For soybean and other fields, chloroestersulfamam or Doujie mixed with herbicide and pine are generally used to spray after the second compound leaf stage of soybean to the fourth compound leaf stage, and ethylcarboxyflufen can be used for peanut field plus herbicide pine or lactofoxalypin for control, and rape field should be dichloropyridinic acid for control.

Is it harmful to corn.

Nope. This is the best herbicide for corn fields.

Corn is used when there are a few leaves.

It is recommended when the spiny is 2 to 4 leaves.

Can corn still be used when it comes out?

OK.

A herbicide that kills prickly vegetables and can beat wheat.

Precautions for the use of herbicides in wheat

1. Herbicides can not be used before 4 leaves of wheat and after jointing.

Because the wheat seedlings before 4 leaves are relatively tender, and the immunity and anti-poison ability are very weak, it is easy to produce pesticide damage. After the jointing period, the wheat enters the booting stage, which is a sensitive period for wheat, and the use of herbicides at this time is very easy to produce pesticide damage (especially dimethyltetrachloride), such as filial piety fruit at this time spraying herbicides, which will cause wheat not heading, deformity, etc., which has a great impact on wheat yield.

2. Do not use herbicides when the temperature is lower than 6.

The use of herbicides in cold weather will affect the efficacy of pesticides. Therefore, it is best to choose herbicides above the average temperature of 6 (the weeding effect is good from 10 am to 3 pm) because Yanhui weeds absorb light and grow vigorously, and the stomata are open and easy to absorb the solution, on the contrary, the temperature is low, and the absorption of the liquid medicine is not ideal.

3. Do not use herbicides when the soil is dry.

The soil should be watered in time when the soil is dry, and the pesticide should be applied in time to ensure the effectiveness of the herbicide. When the moisture content is 40% to 60%, it is most conducive to the exertion of herbicide efficacy.

4. Do not use herbicides in bad weather.

Before the arrival of cold air and before and after heavy rain, herbicides are used in these conditions, which will not only affect the effect of weeding, but also easily cause pesticide damage. Therefore, it is necessary to pay more attention to the weather forecast and weather changes when using herbicides.

5. Herbicides should be sprayed evenly, and no respraying or missing spraying should occur.

The use of herbicides must be evenly sprayed, and the uneven treatment of weeds in places where there is no leakage or less spraying will greatly reduce the spraying effect. It is best not to respray herbicides, which can easily cause wheat yellowing and cause pesticide damage.

6. Do not mix herbicides at will.

The use of herbicides should be in accordance with the instructions or follow the agricultural material store, and do not mix with other herbicides, pesticides, foliar fertilizers, etc., so as to avoid pesticide damage or other adverse reactions.

7. Herbicides should be used separately from insecticides.

Organophosphorus and carbamate pesticides should be used only after an interval of 5 to 7 days, otherwise it is easy to cause yellowing of wheat and leaf burning. This is because organophosphorus pesticides will reduce the ability of wheat to reduce herbicides, and the subsequent use of herbicides can easily lead to pesticide damage.

8. Do not increase or decrease the amount of herbicides at will.

Spraying herbicides should be used according to the instructions, and agricultural materials stores can also be consulted. Do not increase or decrease the dosage at will, the dosage is small can not achieve the purpose of weeding, and the dosage is easy to cause pesticide damage.

9. The secondary dilution method should be carried out before use.

That is, before the application of the drug, the agent is diluted into the mother liquor with a small amount of water, and the prepared mother liquor is added to the medicine barrel during the application, and then the remaining water required is replenished, mixed and sprayed.

It is a common aquatic herb that grows very fast and can easily clog waterways and affect the ecological balance of waters, so effective control measures are needed. At present, the herbicides commonly used on the market are mainly as follows:1

Trifluorochlorocypass: It is a non-selective glyphosate herbicide, which has a good control effect on the combination of spiny cabbage. 2.

Paraquat: is a non-selective glyphosate herbicide that rapidly penetrates into plant cells and disrupts its growth metabolism to achieve herbicide effects. 3.

Shiguoqing: It is a very environmentally friendly herbicide, which is often used for the control and weeding of fruit trees and vineyards, and the control effect on spiny cabbage is also good. It should be noted that the use of weeding agents must be used in accordance with the manufacturer's instructions and use methods, and strictly follow the relevant safety regulations to avoid adverse effects on humans, other plants and the environment.
