What kind of herbicide should I use to grow cotton?

When purchasing and using herbicides, the first step is to choose the herbicide suitable for the grass family according to the type of grass in the cotton field. For broadleaf grasses, it is the dicotyledon weed that chooses the herbicide. In addition, cotton should also be considered whether it will cause pesticide damage, such as 2,4-d butyrin is safe for cereal crops, has a great killing effect on cotton and other broad-leaved crops, and can cause pesticide damage at very low doses.

The main reasons for herbicide damage in cotton fields are: long-term use of herbicides or excessive dosage, improper use, no strict inhibition, spraying cotton balls, resulting in stem and leaf deformity, reduced leaf area, inhibition of photosynthesis, and less peach. If it is too serious, it should be replanted decisively.

The pesticide damage in cotton fields mainly occurs in the two growth periods of cotton. Seeds are damaged by pesticides as not germinating, even if they are not unearthed, the stem or hypocotyl is enlarged, and the cotyledons are in the soil and cannot emerge. The pesticide damage of cotton plants is manifested as the shrinkage of leaves and apex, the shortening of the midrib, and the inward concave tip of the leaf.

Some of them appear as dead spots on the leaves, and in severe cases, the whole leaves dry up and fall off. The growth of some plants is inhibited. The more severe plants all died.

Misuse of "misuse of herbicides" is a common occurrence in production, when herbicides are used as pesticides, or when the wrong type of herbicide is used. Herbicide quality problems, such as active ingredients or poor processing quality, can sometimes cause pesticide damage. <>

Spray with 48% fluoralin EC before cotton sowing, evenly spray with 100 ml of 150 ml of water and 50 kg of water per mu, and mix immediately after application. Before the emergence of cotton seedlings, you can choose 43% cable EC, spray 50 kg of water with 200 300 ml of water, and then spray evenly, after the cotton seedlings grow to 4 leaves, you can use 15% to kill 50 ml of emulsifiable concentrate or 50 ml of caocan emulsifiable concentrate.

Use the dosage strictly as directed. When administering the drug, be sure to take the dose specified in the instructions, and do not increase the dosage at will. It cannot be re-sprayed or leaked.

If there is residual liquid after spraying, it cannot be sprayed in many places on the grass at the edge of the ground to prevent local damage; If the width of one piece cannot be reached by mechanical spraying, the remaining should be manually sprayed to prevent re-spraying or missing spraying. The amount of medicine per mu refers to the actual area. If only sprayed under the film, not sprayed between the films, the area between the films should be subtracted to calculate the amount per mu to prevent excessive spraying.

If sufficient medication has been used before sowing, herbicide should not be sprayed at the time of sowing to prevent pesticide damage. <>

Herbicides for cotton fields should be used, which have been specially developed for cotton and will not cause harm to cotton after use.

Herbicides that do not harm crops should be used, as such herbicides do not harm the yield of cotton and do not affect the growth of cotton.

Acetochlor or butachlor is fine, depending on which one you like to use.

The cotton field uses the cotton grass double cut herbicide of Anhui Zhongtian Zhiyuan Chemical Co., Ltd., which does not hurt the cotton seedlings, and can be sprayed on the whole stupid base field, and it is okay to spray it on the cotton belt such as the flower, and it can prevent and control grasses and broad-leaved weeds at one time. Broad-leaved grass: special effect on nightshade (black bean) and wild rape, which can control Tongquan grass (goose intestine grass), spiny cabbage (thorny dogtooth, green green), gray gray cabbage (quinoa), endive (bitter and bitter green), purslane, Xanthium, fat girl, field spin flower, reverse branch amaranth, amaranth, hemp hemp, bowl flower, morning glory, sausage, water peanut, plantain, concave amaranth, dense spike horse pine nut, knotweed, pig hair cabbage, finch tongue grass, iron amaranth, duck toe grass has a good inhibitory effect.

Poaceae: horsetail, barnyard grass, dogtail grass, cow tendon grass, goldenrod, teff, Kanmai Niang, wild oats, stick head grass, etc., also have a good inhibition effect on perennial grasses of grasses. Perennial grasses with many weeds can be used with two bottles per mu with pyridoxalyxin, which can completely kill perennial grasses such as white grass.

There are many options for this, and the range is also relatively wide, for example, you can choose this one butachlor. Buchlor is generally good for weeding, you can choose to weed before germination, for rice or direct sowing, for those weeds, Huoye weeds and river family has a good effect. This pesticide it also has a great benefit, the performance of weeding is quite stable, there is no problem for sun exposure, because its boiling point has reached more than 190 degrees, and the decomposition of this pesticide should reach more than 200 degrees, and the general sunlight will not have much effect, of course, it is best to avoid rainy days when spraying this pesticide, once it rains, it will be a big trouble.

When choosing this pesticide for weeding, it is necessary to dilute it to a certain extent, generally speaking, different companies produce certain instructions, 300 ml for this 50 kg of water for spray weeding, this dose should be within the standard range, no need to deliberately increase this agent, after all, the effect is the same, it will just be a waste of money. Of course, when spraying pesticides, you must pay attention to protect yourself to avoid this poisoning. <>

Of course, you can also choose other herbicides, such as this diuron and dilometre. These herbicides it has a very good stability, generally speaking, for those weeds killing rate is very thorough spraying on the first day, basically the third day will appear wilted or even yellowed, if there are more weeds, you can also choose to use this glyphosate, this pesticide is also a great weeding effect, but these pesticides are basically sprayed with water. <>

If you don't know which one to use, you can go to this pesticide store for consultation, basically the owner will recommend it to you, after all, they are professional, they will ask you which kind of crop you plant, and then they will recommend which pesticide you use.

When weeding the soil in cotton fields, herbicides such as fluleline, lasso, acetochlor, and butachlor can be selectedWhen weeding stems and leaves, herbicides such as glyphosate can be selected to kill steadily and steadily, and the specific amount of use should be increased or decreased in a timely manner with reference to the number of weeds in the field.

You can use a herbicide, a herbicide, a herbicide, or a glyphosate herbicide.

Herbicides with high safety should be used, such as flulelin, lasso, and acetochlor, which are relatively easy to use and have a high level of safety.

This is a good choice, you can also choose other types, be sure to follow the instructions for proportioning.

Hello: It can be used, generally based on acetochlor herbicides, mainly for horsetail, dogtail grass, tendon grass, barnyard grass, goldenrod, Kanmai Niang, wild oats, early maturing grass, hard grass, teff grass and other annual grasses have special effects, can be used for, cotton, beans, potatoes, rape, tobacco, sunflowers, castor, green onions, etc. So it is recommended to consider using it!

But not on the branches and flowers of cotton!Specifically, I hope it can help you!

Summary. For weeding after cotton seedlings, there are several widely used options. The most commonly used of these include: phosphorus oxide, prochlor, glyphosate.

For weeding after cotton seedlings, there are several widely used options. The most commonly used of these include: phosphorus oxide, prochlor, glyphosate.

These herbicides can effectively control different weed types. However, as each herbicide may be used differently and under different conditions, it is recommended to consult a professional or read the product leaflet before using the herbicide to ensure proper use and minimize potential health risks and environmental impacts.

Is the use of herbicides harmful to cotton seedlings after cotton seedlings?

When using herbicides, it must be noted that improper use will cause harm to cotton seedlings. Especially in the early growth stage of cotton, it is particularly sensitive to herbicides and is susceptible to damage.

Therefore, before using herbicides, it is necessary to understand the use of herbicides and applicable conditions, and operate in strict accordance with the product instructions. In addition, wear appropriate personal protective equipment such as gloves and face shields when using herbicides to reduce potential health risks.

Which herbicide is not harmful to seedlings?

Although the use of herbicides can better control the number and variety of weeds in cotton fields, when using herbicides, appropriate preventive measures must be taken to reduce the damage to cotton seedlings. Here are some suggestions in this regard:1

Choose the right herbicide, for example, you can choose a herbicide with glyphosate as the main ingredient, because glyphosate has a good control effect on many weeds, and the safety of cotton seedlings is relatively high. 2.It is best to pre-moisten herbicides before using them, as moist soil can help improve herbicide absorption and reduce damage to plants.

3.The dosage of herbicide should be used in strict accordance with the guidance on the instructions, and should not exceed the recommended dosage, so as not to cause unnecessary damage to cotton seedlings. 4.

After application, the application equipment needs to be cleaned and rinsed in time to avoid residual herbicide affecting the next use.

In conclusion, the right use of herbicides and the proper precautions can minimize the potential damage to cotton seedlings. However, it is important to note that even if a herbicide with a high level of safety is used, it will still have an effect on the plant in the early growth stage, so it needs to be used with caution.
