This product is a systemic herbicide. The weeds died completely. But die slowly.

In general: broad-leaved weeds are effective in three days. Died in a week.

Poaceous weeds are effective in a week. Ten days to die. Cyperaceae weeds, such as malignant weeds such as aconite.

Results in 10 days. Twenty days later, it is guaranteed to die of "rotten roots". No more resurrection.

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 herbicides used in cotton fields are mainly Heling herbicides. Such as high-efficiency flupyromethalin.

This product is a selective herbicide. It has excellent control effect on perennial stubborn grasses such as reed, white grass and dogtooth root. There was no adverse reaction to broad-leaved crops. The effect is stable at low temperatures.

Applicable crops. A variety of broadleaf crops. Such as: cotton, soybeans, peanuts, potatoes, rape, sunflowers, watermelons, hemp, vegetables, etc.

Prevent objects. Annual and perennial grasses weeds. Such as:

Ma Tang, barnyard grass, Qianjinzi, Kanmai Niang, dogtail grass, cow tendon grass, early maturing grass, wild oats, reeds, white grass, dogtooth root, etc. In particular, it has excellent control effect on perennial stubborn gramineous weeds such as reed, white grass and dogtooth root.

Mechanism of action. After application, this product can be quickly absorbed by the leaves of gramineous weeds and transmitted to the whole plant, inhibiting the growth of plant meristems, thereby killing weeds. It has a long effective period, and has a good control effect on annual and perennial grasses from seedling emergence to tillering and early heading.

It is highly safe for a wide range of broadleaf crops under normal use. It can still show excellent weeding effect under low temperature and drought conditions.

How to use: 1) To control annual grass weeds, apply pesticides at the 3 to 5 leaf stage of weeds, use 20 to 30 ml of this product per mu, mix 20 to 25 kg of water, and evenly spray weed stems and leaves. When the weather is dry or the weeds are large, the dosage should be increased to 30 to 40 ml, and the amount of water should be increased to 25 to 30 kg.

2) When used to control perennial grasses such as reeds, white grass, and dogtooth roots, the dosage per mu is 60 to 80 ml of high-efficiency flupyridoxalin emulsifiable concentrate, mixed with 25 to 30 kg of water. One more application one month after the first medication can achieve the desired prevention and control effect.

Precautions. 1) The addition of silicone additives to this product can significantly improve the efficacy.

2) Poaceous crops have adverse reactions to this product, and the liquid should be avoided from drifting to corn, wheat, water and other gramineous crops when applying pesticides to prevent pesticide damage.

Which herbicide should be used before mulching a cotton field? According to experts, when weeding cotton field soil, herbicides such as flulelin, lasso, acetochlor, butachlor, diuron, and dilochlor can be selected; When weeding stems and leaves, herbicides such as stable killing, precise killing, cover grass energy, grass gram, gram trace, glyphosate and other herbicides can be selected.

Before cotton sowing, 48 fluoralin EC can be used 100 ml - 150 ml per mu mixed with 50 kg of water and sprayed evenly, and the soil can be mixed immediately after application. Before the emergence of cotton after sowing, 43 Lasso emulsifiable concentrate can be used to spray evenly after mixing 200 ml - 300 ml with water per mu and 50 kg; When the cotton seedlings grow to 4 leaves, they can be solved with 50 ml of 15 emulsifiable concentrate or 50 ml of mulchable concentrate mixed with 50 kg of water for stem and leaf solution.

When using herbicides in cotton fields, the following issues should be noted: First, the herbicide varieties used should be appropriate. Second, it is necessary to pay attention to the accurate dosage.

Third, when using herbicides, we should pay attention to factors such as temperature, soil quality and water volume during use, and carefully follow the instructions to operate. Fourth, the equipment for applying herbicides should be dedicated.

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.

Hello dear! Glad you questioned: Hello:

At present, there are some herbicides on the market that can be used for weeding in cotton fields without harming cotton, such as:1Oxidation, glufosinate:

These two chemically synthesized herbicides can inhibit the growth of weeds, and basically do not produce *** for cotton plants, which can better control the weeds in cotton fields. 2.Volatile oils:

Volatile oil herbicides are mainly used to dissolve or dehydrate weeds to achieve the effect of weeding, which is more effective for small weeds and less effective for large weeds. 3.Biological herbicides:

At present, there are some herbicides on the market that are produced from natural materials such as microorganisms and plants, which are basically harmless to cotton, but their herbicidal effect is not as strong as that of chemically synthesized herbicides. It should be noted that any chemically synthesized herbicide will have a certain degree of impact on the environment, so it should be operated in strict accordance with the instructions to avoid adverse effects on the environment.

Dear, I have inquired the results for you: The herbicides that do not hurt cotton in cotton fields are: 1. Carbamates:

It has a strong weeding effect and is suitable for weeding in cotton fields, but it will have certain toxicity to the human body. 2. Propiate alcohols: can effectively inhibit the growth of herbaceous plants, plant inhibitors, safe, reliable and non-toxic, but the dose of base fertilizer should be applied at the same time as the registered dose of herbicides.

3. Nitrosaureas: decompose organic matter in the soil to generate heat, thereby increasing soil temperature, killing plants on the total surface, which can effectively inhibit the growth of plants and can be used for weeding in cotton fields, but the dose of nitrosoureas is larger and has certain toxicity to the human body. 4. Methyl nitrile Hu stove:

It can inhibit the growth of plants, has strong toxicity, and has good safety, but the amount of pesticide application should also be controlled in order to keep cotton from being damaged. 5. Methylcaprylic acid: It can inhibit the growth of planting pants and pants, do not damage cotton, and is used for weeding in cotton fields.

In addition, in order to improve the weeding effect of cotton fields, organic weeding technology can also be adopted, and plant growth regulators, soil bacteria-mediated regulation, pesticide resistance gene detection and crop protection technology can be used to comprehensively control weeds.

Summary. The selection of herbicides after cotton emergence should be based on the specific situation, including the growth stage of cotton, the type of herbicide, the type and density of target weeds, temperature, humidity and other factors. Here are some common post-emergence herbicides for cotton and when they are applicable:

1.Bromazefin: suitable for early seedlings, it has a good weeding effect on some herbaceous weeds.

2.Oxaco: It is suitable for the middle and late stages of the seedling stage, and has a certain weeding effect on some weeds with strong drug resistance.

3.Fenfenoxate: suitable for the middle and late stages of the seedling stage, it can effectively control a variety of weeds, but it is more polluting to the environment and needs to be used with caution.

4.Glyphosate: suitable for the late seedling stage, growth period and flowering stage, it has a good weeding effect on a variety of herbs and broad-leaved weeds.

When using herbicides, attention should be paid to the use in accordance with the requirements of the instructions to avoid pesticide damage and environmental pollution caused by excessive or improper use. At the same time, you should pay attention to personal protection, such as wearing protective clothing, masks, gloves, etc., to ensure your own safety.
