If you want to weed cabbage field, what herbicide works well?

In my house, most of the cabbage is planted and transplanted first, and the seedlings can be carried out in the vegetable house or in the open air. But the transplants are almost always outdoors. The transplantation method should be covered with white transparent mulch, and a small arcade should be set on it, and a small arcade is generally not set up if it is planted in summer, only white or black mulch film needs to be laid.

In the choice of mulch, most of them are mainly black. Because grass is so inhibitive, it can significantly reduce the number of "herbicides."

The amount and frequency of use play a protective role in the soil environment.

I grow cabbage over there, and most of the weeds in the field are mainly broad-leaved, so I mainly consider what plantain isin.

Purslane, mortar, with ordinary herbicides will do. It is the herbicide of "Gillamine EC". It's not even very commonly used.

In my opinion, some friends say that it is very correct to use different herbicides depending on the specific weed, but the actual method used is incorrect. Because my family grows cabbage over there, I first tidy up the land, then spread mulch, and finally move and water. Weeding is carried out on a regular basis.

At present, the most common herbicide in cabbage field on the market, through the absorption of weeds and stems and leaves, inhibits the synthesis of cellular fatty acids and weed necrosis, and is a very selective new field stem and leaf treatment agent, which has a good effect on removing grass weeds in cabbage field.

The effectiveness of weeding depends not only on the quality of the product itself, but also on the soil moisture of the cabbage field. The soil moisture in the field is above 70%, and the weeding effect is good. The soil is too dry, and the weeding effect is relatively reduced.

When using the drug, it is necessary to ensure the safety of cabbage, and the dosage and method of use and time of the selected medicine should be cautious, and strictly abide by the instructions of the drug, especially the dosage. In addition, after the sprayer containing herbicides has used up the herbicides unconditionally, it should be cleaned with soapy water 2 or 3 times to prevent pesticide damage. After spraying herbicides, if you find that the drug burden is too heavy, find a clean cartridge to spray water, dilute the concentration of the liquid with water to reduce the degree of pesticide damage, and at the same time rinse the liquid medicine that has not been absorbed by the leaves, reduce the dose of absorption, and achieve the purpose of reducing the pesticide damage.

If found after spraying with clean water or late, the field cabbage is already in a vulnerable situation, and if the leaf ends are dry and the roots and stems are normal, then the tundra can be sprayed.

Lactone, gibberellin.

and foliar fertilizers to alleviate them. Weeding mulch film Herbicidal mulch should be used to control kale, which contains grass roots or weeding. In order to avoid economic losses, we must not blindly use weeding mulch.

When laying the weeding film, it is necessary to place the herbicide side facing the ground, pull it tight, and press it firmly with the soil. The flour dough should be flat, and the eggs should be finely broken. Otherwise, the drug will accumulate in the recesses and easily harm the vegetable seedlings.

Do not spray herbicides around regular workers who need to coat vegetables before they are officially eaten. If weeds come out, pull them out by hand. Use direct seeding fields and cabbage, broccoli seedlings before sowing or transplanting medicine.

The soil quality is loose, the organic matter content is low, the soil quality is viscous, and the organic matter content is high. Immediately after spraying, mix the soil with a rake, the rake is 4-6 cm deep, and the reward is extinguished in time.

In general, the herbicides we commonly use in cabbage fields are fluleline, acetochlor, dichlor, pendimethalin, isoxagrass and other single agents and mixtures, of course, the premise of choosing to use these herbicides should be based on the corresponding weeds in the field, for example: flulelin, dichlor is mainly for grasses weeds, and acetochlor, pendimethalin, isoxachlor and so on are effective for a variety of grasses in addition to a variety of grasses, but also have a good control effect on a variety of broad-leaved weeds. In addition to these conventional herbicides mentioned above, we can also choose a special herbicide for cabbage fields, which is a pesticide for the study of weeds in cabbage fields, only killing weeds, and has a certain protective effect on crops.

Glyphosate, this herbicide is very effective, and it can kill a lot of grass, which is good for the safety of plants.

Most of the weeds in the cabbage field are broad-leaved, such as plantain, purslane, and gray grass, which can be used with general herbicides, which is the herbicide of "dilomine emulsifiable concentrate". This medicine can control annual grasses such as barnyard grass, horsetail, wild oats, dogtail grass, golden dogtail grass, brachial grass, pigweed, quinoa, mustard greens, dodder seeds and other annual grasses and certain broad-leaved weeds, with a drug of 3000-3750 hectares.

48 Dilomide EC, 48 Lasso EC (alachlor), 50% acetochlor EC, 48% fluoralin EC, 48% Zoleline EC.

All of the above is good.

We can also choose a special herbicide for cabbage fields, which is a pesticide for the study of weeds in cabbage fields, only killing weeds, and has a certain protective effect on crops.

After transplanting, cabbage can be sprayed with dichlor, acetochlor and other drugs the next day after transplanting.

Note: 1It is not advisable to spray pendimethalin, isoxathone and other agents, otherwise it is easy to cause pesticide damage;

2.Try to avoid spraying the medicine on the seedling core;

3.After application, the soil moisture in the field should not be too large to prevent pesticide damage.

Cabbage Introduction: Brassica oleracea L) is an annual or biennial herbaceous plant of the Brassica genus in the cruciferous family, a biennial herb, powdered.

Short, shedd, stout annual stems fleshy, unbranched, green or grayish-green. The basal leaves are thick, wrapped in spherical layers, oblate spherical, milky white or pale green; The biennial stem is branched and has stems and leaves. basal leaves rounded at the apex, narrowed to very short petioles with broad wings at the base, undulating margins without distinct serrations; The upper stem leaves are ovate or oblong-ovate, and the base holds the stem; The uppermost leaf is oblong, about centimeters long and 1 centimeter wide, hugging the stem.

racemes apical and axillary; The flowers are pale yellow, centimeter in diameter; peduncle 7-15 mm long; sepals erect, linearly oblong; The petals are broadly elliptic-obovate or nearly rounded, slightly absent at the apex, and the base is abruptly narrowed into claws, 5-7 mm long. The long-horned fruit is cylindrical, slightly flattened on both sides, the midrib is prominent, the beak is conical; The fruit peduncle is thick and spreads erect. The seeds are spherical and brown.

The flowering period is April, and the fruiting period is May.

According to its composition, the herbicides in rape fields that kill monocotyledon weeds can be divided into four categories: Essence grass gram, Quinethoxalin, Qi Divi, Jin Gai, Jin Bang Ke, etc.; Kill steadily, kill steadily, etc.;

Efficient grass covering, grass covering, etc.; Mighty horses, hussars, etc. Gotek, Haoshiduo, Grass Killer, Oil Grass Mai, etc.

Soil was sprayed with 48% fluoralin EC, 25% herbicide wettable powder, 25% amioxaphos EC, 60% butachlor EC, 50% Dahuili powder, 72% Dool EC or 50% herbicidal EC before planting or before transplanting. Hand in hand.

Cabbage needs to be sprayed before transplanting, and there are many soil sealing agents used before cabbage transplanting, such as fluoralin, acetochlor, dichlor, pendimethalin, isoxagrass and other single agents and mixtures, and the corresponding herbicides can be selected according to the grass phase in the field. Among them, flulenin and dichlor are mainly aimed at gramineous weeds, and acetochlor, pendimethalin, and isoxachlor are not only effective against a variety of grasses, but also have good control effects on a variety of broad-leaved weeds. It is easier to control gramineous weeds in the field during the growing period of rapeseed, and there are many safe and efficient drugs that are applicable. Broad-leaved weeds in the field are difficult to control, and there are few suitable safe and efficient drugs, so the soil sealing treatment should use drugs with good control effect on broad-leaved weeds as much as possible.

After transplanting cabbage, it is not advisable to spray pendimethalin, isoxathor and other agents, otherwise it is easy to produce pesticide damage, you can spray dichlor, ethylpyridine and other drugs the next day after transplanting, and try to avoid spraying the medicine on the seedling heart. After application, the soil moisture in the field should not be too large to prevent pesticide damage.

Glyphosate herbicide, which is widely used in agriculture, has strong systemic conductivity, can be conducted to the underground part through the stems and leaves, and has strong destructive power to the underground tissues of perennial deep-rooted weeds, and can reach a depth that cannot be reached by general agricultural machinery.

How glyphosate works.

It is to inhibit the acetinyl-shikikin phosphate synthase in plants, thereby inhibiting the conversion of shikimiin to phenylalanine, tyrosine and tryptophan, so that the synthesis of protein is disturbed and the plant dies. After glyphosate is put into the soil, it is inactive by combining with iron and aluminum ions, and has no adverse effect on seeds and microorganisms in the soil.

Precautions for the use of glyphosate.

1.Glyphosate is a biocidal herbicide, and it is important not to pollute crops when applying pesticides to avoid pesticide damage.

2.For perennial malignant weeds, such as white grass, fragrant aconite, etc., one more drug should be applied one month after the first application to achieve the ideal control effect.

3.Adding an appropriate amount of diesel fuel or laundry detergent to the liquid medicine can improve the efficacy.

4.On sunny days, the effect of medication is good when the temperature is high, and it should be sprayed in case of rain within 4 to 6 hours after spraying.

5.Glyphosate is acidic, so plastic containers should be used for storage and use.

6.Spraying equipment should be cleaned repeatedly.

7.When the packaging is damaged, it may return to moisture and agglomerate under high humidity, and crystals will precipitate during low temperature storage.

8.It is a systemic conductive herbicide, and attention should be paid to prevent the pesticide mist from drifting to non-target plants and causing pesticide damage.

9.It is easy to complex with calcium, magnesium, aluminum and other ions to lose its activity, and clean soft water should be used when diluting pesticides, and it will reduce the efficacy when mixed with muddy water or dirty water.

10.Do not mow, graze and plough the ground for 3 days after application.

Glyphosate in the broad sense is a general term for various glyphosate salts, and glyphosate in the narrow sense refers to glyphosate acid.

Glyphosate itself is insoluble in water, so it is made into various salts that are easily soluble in water for application, such as ammonium salt, isopropylamine salt, potassium salt, sodium salt, dimethylamine salt and other glyphosate salts.

Comparison of activity (absorption and conduction of glyphosate):

Glyphosate potassium salt, glyphosate dimethylamine salt, glyphosate isopropylamine salt, glyphosate ammonium salt, glyphosate sodium salt.

30% glyphosate acid = 33% glyphosate ammonium salt = 41% glyphosate isopropylamine salt = 37% glyphosate potassium salt = 38% glyphosate dimethylamine.

Answer: Use 10% glyphosate water agent to control annual weeds, the appropriate dosage is 50 times the solution, the appropriate dosage is 40 times the solution for the prevention and control of perennial weeds, and the control of small shrubs can be sprayed with 30 times the solution, which is conducive to achieving a good control effect.

During the period, according to the type and growth of weeds, 10% glyphosate aqueous agent is generally used to prevent and control horsetail, dogtail grass, early maturing grass, cow tendon grass, etc., the appropriate dosage is about 50 times the liquid, the appropriate dosage is about 40 times the liquid for the prevention and control of mugwort, plantain, fragrant aconite, etc., and the appropriate dosage is about 30 times the liquid for the prevention and control of white grass, scissor strands, spiny cabbage, etc.

Summary. Hello The special herbicides for cabbage seedlings include Refined Grass Gram, Refined Quinolyphine, Qi Divi, Jingai, and Jinbangke.

Hello The special herbicides for cabbage seedlings include Refined Grass Gram, Refined Quinolyphine, Qi Divi, Jingai, and Jinbangke.

These herbicides are safe and effective pro.

Herbicides refer to a class of substances that can completely or selectively kill weeds to eliminate or inhibit plant growth, also known as herbicides.

Can you grow cabbage after taking the herbicide diclobidolinate?

Yes, yes, dear.

Now that the corn fields have been beaten with chlorpyramisulfuron, can we plant cabbage next spring?

It is possible to plant a pro.

Different grasses need to be sprayed with different herbicides to target the roots. 1-year-old grasses such as horsetail and cow tendon grass and broad-leaved weeds with small seeds, such as quinoa and knotweed, generally use 48% fluoralin EC or 500 0 acetochlor EC; However, 8% high-efficiency cover grass can effectively control 1-year-old and perennial grassy weeds, but cannot control broad-leaved weeds and sedge weeds. The spraying time of pesticides should be determined according to the growth of the root of the plantation.

1. What herbicide is used for the grass in the root field of Banlan

Hand Banquet % fluorinyl EC: It can effectively control 1-year-old gramineous weeds, such as horsetail, beef tendon, dogtail grass, etc., as well as broad-leaved weeds with small seeds, such as quinoa, knotweed, amaranth, purslane, etc., with an effective period of 2-3 months in the field.

0 acetochlor EC: It has special effects on a variety of 1-year-old grasses and can also treat some broad-leaved weeds with small seeds.

Efficient grass covering: effective control of 1-year-old and perennial grasses weeds, and it is very safe for the roots of Radix indigo.

Second, when is the effect good?

Fluoralin EC: suitable for weeding before sowing of medicinal materials, spray the topsoil of the medicinal field with 80-100 ml of 48% fluoralin EC per mu on 40-50 kg of water.

Bi manuscript silver 0 acetochlor EC: suitable for weeding before sowing or after transplanting field, with 70-75 ml of agent per mu to evenly spray 40-60 kg of water on the topsoil of Jingwen medicine field.

Efficient grass covering: suitable for weeding after the emergence of medicinal materials, 30-40 kg of water per mu with 70-80 ml of 6% gram grass star emulsifiable concentrate, sprayed when the average height of weeds is less than 5 cm.

I wonder if this will apply?

Herbicides for medicinal materials (Coptis chinensis, parsnip, Ophiopogon vulgaris, Angelica dahurica, Ligusticum Chuanxiong, Duhuo, Angelica sinensis, Bupleurum chinensis, Huoxiang, Salvia) and other post-seedling special.

80 grams bag, simple 15 yuan bag. Color package 20 yuan bag 100 bags box, 1 bag with 1 acre).

Features: This product is a selective systemic conductive herbicide, which is mainly absorbed into the roots of plants through stems and leaves, inhibiting photosynthesis and causing plants to lose green to dry up and die.

In general, the best control effect is at the 3-5 leaf stage of weeds. 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. This product can control a variety of annual gramineous weeds, broad-leaved weeds and sedge weeds. After application, it can be effective in the topsoil for about 2 months.

1 Application:

Coptis chinensis, Angelica dahurica, Parsnip, Ophiopogon vulgaris, Lily, Ligusticum Chuanxiong, Bupleurum chinensis, cumin, Qianghuo, Duhuo, Angelica sinensis, Tangmu, Beisha Shen, Wheat fritillary, Polygonatum polygonatum polygonatum vulgaris, Polygonatum japonica, Polygonatum chuanchuanensis, Zhimu, Crow petal, Asparagus, Houttuynia cordata, Poria cocos. , scutellaria, motherwort, nepeta, Huoxiang, salvia, lavender, mint and other crops. (Crops that are not marked should be tested in a small area before they can be promoted on a large scale).

2 How to use:

This agent must be diluted twice, that is, the powder is poured into a small bowl, a small amount of water is added, and it is completely dissolved. After making the blister-free pharmaceutical mother liquor, pour the mother liquor into the sprayer and add enough water. Do not pour the powder directly into the nebulizer for the secondary dilution method.

It's critical. If the secondary dilution method is not used correctly. There are also blisters in the potions.

It is easy to produce pesticide damage.

3 Dosage:

1) Pre-seedling use: 2-3 days after sowing medicinal materials, 80-100g30-50 kg with water. Uniform spraying;

2) Dosage after seedlings: all kinds of medicinal materials are in the three leaves and one heart. 60-80g per mu, 30-50 kg with water. evenly spray the seedbed;

3) After transplanting seedlings: after transplanting seedlings of medicinal materials. 80-100g per mu, 30-50 kg of water, evenly sprayed;

4) When controlling older grasses and weeds, add 2 bags (15nl bags) per mu15% Jingkui Heling Gai Caoning, Weiba and other effects are excellent;

4 Precautions:

1) The soil must be moist when using medicine, and the medicine should be used when the temperature is low in the afternoon in the high temperature season, especially; Sprayers that have used other pesticides must be cleaned. If the soil is dry and the temperature is more than 28, it is easy to produce pesticide damage, 2) please pay attention to ventilation when using the warm greenhouse, and the small greenhouse should be used after removing the film for seven days. Otherwise, it is easy to cause drug damage;

3) The organic matter content of sandy soil is low, and the effect of topsoil is poor.

4) This agent should be sealed, dry and stored in a cool place, away from children, food and feed;
