What herbicides can get rid of bitter herbs in corn fields

The use of paraquat herbicide in maize fields can kill bitter herbs. When the maize plant is more than 1 metre tall, spray the weeds (bitter herbs) with 100 ml (contact herbicide) of 20% paraquat mixed with 15-20 kg of water, stir well. Weeds die in 2-3 days.

Note: Weeds that do not come into contact with the liquid at the weed growth point will be resurrected within 7-10 days after death.

Ultra-efficient corn herbicide. Sweet corn herbicide after seedlings "grass." Wide. Sha weeds are removed".

35g bag "1+1+1".$15 bag. 250 bags. 2 bags with 1 acre).

One. Features:

After seedlings. All over the field. "Poaceous weeds. Broadleaf weeds. Cyperaceae weeds" are removed. While effectively controlling the unearthed weeds. It is also effective in sealing off ununearthed weeds. Unmatched by any other herbicide.

1.Fragrant aconite against malignant weeds. Tian Xuanhua and so on have special effects. Make sure the roots rot within two weeks.

2.Excellent control effect on all gramineous weeds. Especially Tsushima Don. Cow tendon grass. Dogtooth root. Dogtail grass. Barnyard grass. Ice grass. False sorghum grass. Self-generated wheat seedlings. Look at Mai Niang and so on.

3.To broad-leaved weeds such as spiny bracts. Trifolium lanceola. Cassia . Pigweed. Xanthella. Thousand grasses. Win red thistle. Euphorbia. Big melon dragon. Chrysanthemum. Amaranth. Amaranth retroflex and other excellent control effect

Two. Application:

to corn. (Sweet corn medicine is different) highly effective and safe. Can be sprayed all over the field.

It doesn't hurt corn. (But focus on directional spraying whenever possible.) ).

Do not deliberately spray on the corn. Especially inside the corn cob. In the 3-4 leaf stage of corn.

Weeds work best when they are 10-15cm. Weeds, especially grasses, should be appropriately increased when the amount of medicine is more than 20cm.

Three. Results:

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

In general: broadleaf weeds are effective on the same day. 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.

Four. 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.

Every 660 square meters with 2 bags of water 25 30 kg, the spray should be meticulous and thoughtful, so that there is no heavy spraying and no leakage.

5. Precautions:

1) Keep the soil moist when using medicine. Sprayers that have been sprayed with other pesticides must be washed clean, if the soil is dry. If the temperature exceeds 28 or more, it is easy to produce pesticide damage, and in the high temperature season, it can be used when the temperature is low in the day;

2) Keep it in a sealed, dry and cool place, away from children, food and feed;

3) Please pay attention to ventilation when using the greenhouse, and the small greenhouse should be used after removing the film for seven days; Otherwise, it is easy to cause drug damage;

Changing stubble is the best choice, and it will be gone after two years of changing stubble. Herbicides are not good.

The herbicide options for bitter herbs are as follows:

1.Herbicide selection of bitter herbs: The use of herbicides for bitter herbs requires the selection of glyphosate herbicides, such as Roundup, Jindunfu, etc., which can effectively kill various weeds such as bitter herbs, and can cut weeds and remove roots.

2.Bitter herb introduction: It is a wild vegetable, and its young leaves and shoots can be eaten as vegetables.

It has a unique flavor that can supplement the nutrients needed by the human body and enhance the body's immunity. Bitter herb is widely distributed in China and is one of the common wild vegetables in rural areas.

3.Introduction to herbicides: Herbicides refer to agents that can cause weeds to die completely or selectively, also known as herbicides, which are used to eliminate or inhibit plant growth.

I hope the above information is helpful to you, and if you have any other questions, welcome to let me know.

Cyclozinone herbicide. Cyclozinone herbicide is a broad-spectrum herbicide that is systemic and can quickly wither after being absorbed by the leaves of bitter herbs.

Because of the spring jujube, if you want to get rid of bitter herbs, use cyclazinone herbicide, dilute it at a ratio of 1:1000 and spray filial piety, spray once, enough to kill this weed. However, when using it, it must not harm other agricultural scraps.

Summary. Dear, it's a pleasure to serve you. Bitter herb is a common weed that can affect corn growth and yield.

At present, the commonly used chemical herbicides are glyphosate, glufosinate, glufosinate, etc., and it is necessary to pay attention to the concentration of the agent, the time and method of application in the process of use. Glyphosate is a broad-spectrum herbicide that can be used to control bitter herbs in corn fields. In general, the best time for glyphosate spraying is when the seedlings are 10-15 cm tall and the concentration of the agent is 40%.

The following points should be paid attention to when using:1Fine Mist Spraying:

Fine mist spraying can improve the utilization rate of glyphosate and prevent the loss of chemicals. 2.Avoid droplets falling on corn plants:

Glyphosate does not have much negative impact on the growth of corn, but it is still necessary to avoid letting the liquid fall directly on the plant when spraying, so as not to have unnecessary effects on corn. 3.Before using glyphosate, take a drug susceptibility test:

Some weeds have developed resistance to glyphosate, so drug susceptibility tests should be performed before use to ensure that weeds are effectively eradicated.

Some weeds have developed resistance to glyphosate, so drug susceptibility tests should be performed before use to ensure that weeds are effectively eradicated.

Hope the above information can help you, is there anything else you need to consult?

You can't use glyphosate after corn seedlings.

You're right, glyphosate cannot be used at the corn seedling stage. Glyphosate is a non-selective herbicide that can cause damage to crops such as corn in addition to having a killing effect on weeds such as bitter weeds. Therefore, at the maize seedling stage, we do not recommend the use of glyphosate to control weeds such as bitter weeds.

At the seedling stage of corn, we can use other herbicides to control it. However, it should be noted that before using any chemical herbicide, please be sure to read the product instructions in detail, and follow the dosage and method recommended by the instructions to ensure safe use. In addition, physical or biological control measures can also be used, such as hand-pulled weeding, mulching control, microbial preparations and other methods of control.

In the corn field, the curvature can be used to remove the herb.

Atrazine herbicideIt can control a variety of annual grasses and broad-leaved weeds. It is suitable for corn, sorghum, sugarcane, fruit trees, nurseries, woodlands and other dryland crops to control horsetail, barnyard grass, dogtail grass, sedge, 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; In the northeast region where the soil organic matter content is greater than 3% to 6%, 200 to 250 grams of 50% wettable powder or 200 to 250 grams of 40% suspension agent per mu, 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. In the continuous cropping area of maize and winter wheat, in order to reduce or eliminate the pesticide damage of atrazine to wheat, atrazine can be used to reduce the amount of atrazine and mix it with herbicides of grass jingjin, lasso, dol, 2,4 to d butyl ester, bannong 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 eradicate the unearthed grass and overwintering miscellaneous lines, and then use 250 to 300 grams of 40% suspension agent per mu, and evenly spray the soil surface with 40 kg of water.

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, mainly on dicots, focusing on closure, and 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 residual 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 needs to wait about 40 months to plant, and tobacco, alfalfa, sugar beet, rape, flax and other crops also need to go through 24 months before planting.

Whoever kills dicots can kill bitter herbs.

1. Kumai is an annual herbaceous wild vegetable of the Asteraceae family, which has a variety of health care effects. Ryegrass is a grassy grass and is one of the grasses with the highest yield of digestible matter.

Commonly used amide herbicides and triazine herbicides in corn have strong killing ability against these two plants.

2. There will be two problems in planting forage in the corn field, one is that the grass will compete with the corn for fertilizer, and the other is that the grass will affect the ventilation in the corn field after the grass grows taller, both of which will affect the yield of corn, and at the same time, because of the shading of corn, the growth of forage is not very good, so it is not recommended to plant forage in the corn field.
