How to weed leeks after sowing, can you use diquat to quickly remove weeds after leek sowing

It is recommended to use acetochlor, and it is recommended that you try a small range of several new amide and pyrimidine salt herbicides here. (As a reminder, herbicides are prohibited in the production of Aa grade green food vegetables, but pre-budding herbicides can be used in the production of grade A green food vegetables.)

First, the use of pre-bud herbicides. That is, before the weeds are unearthed, by spraying on the ground, the grass buds are killed when they are unearthed, and this type of herbicide is called pre-budding herbicides. For example, the current production of widely used Shi Tian Bu (weeding) and Jindur (refined metolachlor) are the same.

These two herbicides are widely used for pre-bud weeding of beans, onions and garlic, celery, coriander, peanuts and ginger, and can also be used for soil treatment before planting of melons, eggplants and leafy vegetables, with good effect and high safety. Except for Liaceae weeds, most of the monocotyledonous and dicoted weeds can be controlled, and the best effect is to kill gramineous weeds. Now take 96% of Jindur as an example to introduce its use:

Weeding before the sprout of vegetables is to spray herbicides on the ground after the vegetables are sown, and it is best to use them after good soil moisture or watering. Spray 50-80 ml per mu, valid for up to 40-70 days. When the weeds grow and can no longer be used, they can be sprayed after the weeds are removed.

After use, the sprayer can be cleaned with water before it can be used, and it will generally not cause pesticide damage to crops. (Note: In 2005, the original manufacturer no longer produced "Doer" herbicide, and the current "Doer" herbicide on the market is a counterfeit product, please pay attention to vegetable farmers.)

Second, the use of biocidal herbicides. This type of herbicides are biocidal herbicides, among which gram and cree (the active ingredient is paraquat) are imported paraquat, which can be used for weeding between the rows of high-stemmed vegetables in the open field, such as onions and garlic, beans, melons, nightshades, etc., which are effective for most weeds during the growth of crops, generally with 250 ml of four sprayer water per mu, and can kill weeds 1-2 hours after spraying in high temperature weather (above 30 degrees Celsius). It will not be effective in case of rain 1 hour after spraying. These two herbicides only kill the green part, but not the roots, and are generally valid for 30-40 days.

Special attention should be paid to the following two problems when using: one is the herbicide of incidus, as long as it is green plants are killed, so the directional spraying method must be used, that is, the nozzle is close to the ground to face the weeds, and it is strictly forbidden to spray on the vegetables. Second, once the crop suffers from pesticide damage, you can use 1 sprayer of water and 1 tablespoon of alkaline flour (baking soda) to spray, and then spray Yunda 120 plus Aiduo to alleviate it.

The sprayer that has used herbicide should be rinsed repeatedly with alkali, and tested before use to prove that it is correct before using the sprayer.

Question: Zhang Chunrong, Fanchuan Town, Jiangdu City: What kind of medicine can be used to control weeds after leek sowing?

Can acetochlor be used in soil sealing? Answer: According to relevant information, leeks are more sensitive to acetochlor and should not be used for soil closure treatment.

After sowing leeks, before emergence, promethonyl, pendimethalin, and puttylene can be used for soil sealing treatment. Among them, prometrinet is mainly used to control broad-leaved weeds, and pendimethalin and sec-butylene can be used to control grasses and some broad-leaved weeds. It can be selected according to the grass phase in the field.

During the growth period of leeks, stem and leaf treatment agents such as quinoxalin and high-efficiency flupyrimethoxalin can be used to control gramineous weeds, which is safe for leeks. To control broadleaf weeds in leek fields, there is no safe pesticide to choose from for the time being. According to some information, capryloyl bromobenzonitrile can control broad-leaved weeds in leek fields, but improper use may cause contact spots, and a small area test should be carried out before large-scale use to ensure safety.

Summary. Hello, what herbicide kills leeks and removes roots? Pro-systemic conductive herbicides can be used, sprayed on a certain leaf of the plant, and after being absorbed, it can be conducted to other leaves, flowers, fruits and roots, so that the plant dies.

Such as glyphosate, prometrinet, cover grass, stable kill ether, etc.

Hello, what herbicide kills leeks and removes roots? Pro-pro can choose systemic herbicide to spray on a certain leaf of the plant, and after being absorbed, it can be conducted to other leaves, flowers, fruits and roots, so that the plant dies. Such as grass edge tung glyphosate, promethonet, cover grass energy, steady killing positive imitation ether, etc.

After cutting the leek, it is recommended to apply special herbicides such as pyridoxalin (Jingwen Lugao source killing), Fenflupyroxaline (high-efficiency grass cover), Fenazole Herbanine (Weiba), Jingwa Wo Helin (Essence Grass Gram), and Sullenedimidine (Na Catch) and other special herbicides. If you want to get rid of leeks, you can only use herbicides, herbicides can eliminate stubborn grasses, leeks must also be able to buy some herbicides, hit the water, hit the leeks, and you're fine.

Summary. Herbicides can be used.

1. Use in front of leek seedlings:

1. Use 48% dilometrine, 3 to 3 75 liters per hectare, and apply the pesticide after sowing in the leek seedling field, that is, before the emergence of leeks.

2. Use 50% promethonet WP 1 5 grams per hectare to apply pesticides after leek sowing and before leek emergence;

3. Use 50% promethonyl WP 1 5 to 2 25 grams per hectare, and apply the pesticide after the wound heals and grows new leaves after the old leeks are cut.

Can you use diquat to get rid of weeds quickly after leek sowing?

Herbicides can be used. 1. Use before selling simple vertical leek seedlings: 1. Use 48% dilometrene, 3 to 3 75 liters per hectare, and apply pesticides after sowing in leek seedling fields, that is, before leeks emerge.

2. Use 50% promethonet WP 1 5 grams per hectare to apply pesticides after sowing medium and large leeks before seedlings emerge; 3. Use 50% promethonet WP 1 5 to 2 25 grams per hectare, and apply the pesticide after the wound heals and grows new leaves after the old leeks are cut.

Can leeks be sealed with metolachlor after sowing?

Not recommended. Meolachlor is a broad-spectrum post-sowing pre-emergence herbicide. For a variety of crops such as voltain:

Soybeans, corn, cotton, peanuts, potatoes, cabbage, spinach, garlic. It can be used on crops such as sunflower, sesame, rape, radish, sugarcane, etc., and can also be used in orchards and other legumes, cruciferous, solanaceae, Asteraceae and umbelliferae crops, which can prevent and control annual gramineous weeds and some dicoted weeds at a delay. Sesame fields can be sprayed on the surface with 100 150 ml of 50% alachlor emulsifiable concentrate per mu before sowing seedlings, and 30 50 kg of water can be sprayed on the surface, which has a good control effect on grasses and broad-leaved grasses.

Summary. I believe many people know that leek seedlings are a very delicious vegetable, but there will be various problems in the planting process, such as weeding. So, which herbicide should be used for weeding after planting leek seedlings?

First of all, we do not recommend the use of chemicals for weeding leek seedlings, because the chemical components contained in herbicides can affect the growth and quality of leeks. Moreover, many herbicides are harmful to the environment and human health. Therefore, in order to ensure the growth quality and health of leek seedlings, we recommend using manual weeding.

You can use knives, shovels and other tools to dig up the weeds around the leek seedlings, increase the aeration of the soil, maintain soil moisture and air permeability, provide sufficient nutrients and water, and promote the growth of leeks. In conclusion, after planting leek seedlings, it is best to use manual weeding and avoid the use of chemicals. Be sure to pay attention to the growing environment of leek seedlings and follow standard practices for planting and weeding to obtain healthy, delicious leek seedlings.

You've done a great job! Can you elaborate on that?

Leek seedlings are a very good vegetable, and its cultivation and post-management require our special attention. After the leek seedlings grow, in addition to watering and fertilizing, we also need to use herbicides to remove weeds to ensure the healthy growth of the leek seedlings. When choosing a herbicide, you need to pay attention to the following aspects:

First of all, we need to choose a herbicide specifically for leek seedlings, and look for the label on the package when buying. Secondly, the use of the herbicide should be carried out in accordance with the instructions on the instructions, and improper use will sometimes endanger the health of leek seedlings. Finally, we need to pay attention to the effect time of the herbicide, if the leek seedlings will continue to grow for a period of time after the herbicide is used, then the improper use will affect the growth of the leek seedlings.

In this way, with these preparations, we can use the herbicide exclusive to leek seedlings with confidence, so that leek seedlings can grow healthier and more delicious.
