There are still greens in the vegetable field, what herbicide is used to control the weeds without h

Artificial weeding: It can effectively solve the problem of overgrown weeds. Cage cover mulch or straw:

Spraying pre-germination herbicides: Before planting vegetables, pre-germination herbicides can be sprayed, such as field supplements and flulelin.

Spraying pre-germination herbicides, which can make weeds completely or selectively die, also known as herbicides, are used to eliminate or inhibit the growth of plants.

1. Before planting vegetables, pre-germination herbicides can be sprayed, such as field supplement, fluoralin, etc., generally 33% field supplement per mu dosage is 100-150ml, evenly sprayed on the soil surface, 48% fluorolein is mixed into the soil to kill weeds.

2. And in the soil, it can be strongly adsorbed by clay colloids and soil organic matter, so it is not easy to be lost by rain, and the soil can be sprayed with 150-200ml of water and 45kg per mu.

3. Then mix the soil 2-3cm deep, 7 days later can be planted vegetables, in order to ensure the effect of herbicide application, the furrow surface can be leveled before application, so that the soil is finely broken.

It is possible to weed by hand.

1. Artificial hoeing is a more reliable method, whether it is peppers, eggplants, tomatoes and other vegetables, or cucumbers, beans and other vine vegetables, and then coriander and lettuce such leafy vegetables, artificial hoeing methods can effectively solve the problem of overgrown weeds.

2. Because farmers generally grow vegetables in small vegetable gardens, the place is not large, and it can be solved by manual work, but the large-scale planters can't keep up, so they have to use herbicides to weed.

3. The only bad thing is that it takes a long time to hoe the grass manually, because every time it rains, you have to hoe the grass once, otherwise the vegetable garden will be overgrown with weeds.

After planting lotus root for 7 10 days, or 1 2 days before the emergence of the lotus root, the temperature is above 25 (the water temperature is stable at 20), the field is kept in a 3 5cm water layer, mixed with soil or combined with chemical fertilizer sprinkled (15 kg of weedyl mixed with water spray or the original drug is thrown), and the water layer is maintained for 5 7 days after application, and then normal management.

In addition, herbicides such as moose, moxa, barnyard and other herbicides in paddy fields can also be used in aquatic vegetable fields.

Summary. Hello, glad for your question. There are more weeds in the vegetable field, and it is advisable to use weeding, Guoer, and weedin for soil treatment after sowing.

What herbicide is better to use if there are a lot of weeds in the vegetable field?

Hello, glad for your question. There are more weeds in the vegetable field, and it is advisable to use weeding, Guoer, and weedin for soil treatment after sowing.

Lettuce patch. The herbicides commonly used in the pre-seedling treatment of lettuce are high herbicide, aniline, chloraniline, flumichlor, and chlorachlor.

Because green vegetables are leafy crops, herbicides should be used early, and chemical herbicides should not be used in the middle and late stages of green vegetables to avoid residues on green vegetables.

1. Before sowing and seedling: spray soil treatment agent with poor internal conductivity in the green vegetable field to avoid direct contact between seeds and pesticides, such as: field supplement, fluorin, etc. plus weeding safety additives.

2. After sowing and seedling, at the 2-3 leaf stage of weeds, the stems and leaves can be treated with emulsifiable concentrate, herbicidal ether emulsifiable concentrate, etc., plus safety additives.

The weather is hot, weeds are very difficult to remove, weeds are our farmland, it is the most annoying in the vegetable garden, it happens every year, sometimes the weeds are more and more prosperous, especially after the rainfall, even more. Weeds in the vegetable garden, we generally do not take the use of herbicides, their own vegetable garden, grow vegetables, they are used to eat, do not use pesticides to remove weeds, what are the safest and commonly used methods?

After the summer and winter, the hoe did not stop. In the summer, morning and evening, they go to the fields, and the most common is hoeing, which not only removes weeds, but also works well in loose soil. For growing vegetables, the growing conditions are excellent and one of the most useful methods.

For farmland mulching film, this method is now many, when planting, when the film is covered, when the seedlings grow up, the small seedlings are torn, the weeds will be covered with the film, it is difficult to add air at high temperature, it is difficult to sunlight, these weeds are difficult to grow, and the use of straw is also similar to film, it can not only cover the land, so that the grass can not come out, but many young grasses are killed, but also to maintain the soil temperature, the growth of fruit trees, reflective shine can enhance the sparkling of fruit trees. Sweet fruit, but ripe has a good effect. For vegetable gardens in the growing area, we use the most manual weeding in addition to hoeing, after rain or after watering, the soil is soft, it is perfect for weeds.

It is also possible to look for the natural enemies of weeds, this method is relatively simple and is the natural enemy of weeds, cultivating this crop is cultivated in the local growth of weeds, passing through the characteristics of the plant and using the characteristics of both, and then reaching the weeds.

In addition to the frequent method of removing weeds, there is also a baking soda with some laundry detergent spray that can suppress some of the long weeds, but for more, we still need to take the grass and go in to remove the weeds, which is the most important thing to make the soil. For example, cultivated sunflowers are removed from cultivated sorghum raised to destroy large nectar, and cultivated to eliminate bamboo whips.

There are a lot of weeds in the vegetable field, and if you don't want to use herbicides, you can plough the soil and weed, select weeds from improved seeds, stubble, weeding with organic fertilizer at high temperature, and improve the coverage of crops as soon as possible.

I think if you don't need herbicides, you have to pull them out by hand, and this person has to be diligent and hoe every day. Just like our ancient peasants.

If you don't want to use herbicides, you can set them on fire. This can increase the grass ash in the field and increase fertilizer for the growth of vegetable seedlings. At the same time, it is very convenient and worry-free, but the bad thing is that it increases carbon dioxide emissions.

If we don't want to use weeds, we can turn it up with a hoe and cut off the roots of the weeds from the soil, and we can achieve our purpose of weeding.

At this time, you can choose to pull the grass manually, but it takes a long time, but in this case, the grass is relatively clean.

If you don't want to use herbicides, you need to spend a lot of effort on your own, often working in the fields, uprooting some weeds, but it takes a lot of time.

You can choose to pull the weeds manually, as manual weeding can make your own vegetables grow better.

Obviously, can artificial hoeing still be used, of course not, it is time-consuming and laborious, and the effect is not necessarily good. That's why we're using what people often refer to as herbicides.

There is nothing wrong with herbicides that can control weeds, but naturally they can also kill plants and have an impact on the vegetables grown, so should they continue to be used?

There are several reasons for this:

First, there is nothing wrong with the herbicide being toxic, but its herbicidal effect is still there. Many people complain that herbicides are very harmful, almost can make plants die, I think it is due to the failure to grasp the amount of herbicides, no matter what medicine is used, there must be a suitable degree, beyond this limit, the natural harm outweighs the benefits.

Second, herbicides can save time and labor costs.

It can be used for other plant care species, and from this point of view, although the herbicide is toxic, the weeds can be removed, and this can be achieved.

Third, herbicides are toxic, and there are residues on vegetables, not necessarily because farmers are lazy. If I grow a little at home, it's enough to make sure I have enough to eat, and there is no need to use herbicides. If you want to eat green pollution-free, no pesticide residue fresh vegetables, you can grow your own, there is no need to buy other people's things in the market, in the final analysis, it is not that we have no time, no energy, no land.

Therefore, herbicides have their benefits, we can use them, and we need to grasp the dosage and control it within the appropriate range. Farmers are lazy or not, the people in the city have food to explain the problem, there is no need to have such strange thoughts, the use of herbicides is lazy.

There are many types of herbicides, depending on what herbicide you are appliing, if you apply glyphosate, it will be absorbed through the vegetable leaf stem, the roots will die, the vegetables will die, if it is paraquat, then look at the amount applied, if the amount is large, the vegetables will die, if the amount is not large, then sprinkled to **, ** will produce spots, will not cause the whole vegetable to die. If it is a selective herbicide, it depends on whether the vegetable is broad-leaved or grassy, if the vegetable is broad-leaved, then use a gramineous herbicide, if it is a grassy vegetable, choose to use a broad-leaved herbicide. In short, you should be specific in your question, indicate what herbicide is being applied and what kind of vegetable is the vegetable?

People are good!

1. Eat leafy vegetables.

For example, cabbage, cabbage, green leafy vegetables, such as Chinese cabbage, camellia, cauliflower, cabbage, celery, lettuce, artemisia, spinach, bracken, amaranth, coriander, etc. The use of herbicides is not recommended for this type of vegetables. If necessary, Dahuili and weeding can be used for soil treatment before seedlings after sowing (celery and lettuce should not be used for Dahuili) or Guoer, weeding, and vegetable Zhuang No. 2 can be used for soil treatment before planting.

Celery seedling field can be used for soil treatment before seedling sowing with dilodiamine, gol and dioxazim; Lettuce and vegetables can be treated with Guoer, weedin, and Vegetable Zhuang No. 2 in the soil before planting; Artemisia annua and amaranth can be treated with pre-seedling soil after weeding and sowing; Spinach plots that do not have wells around can be used for chlorpyra; Coriander dididilamine is treated with pre-seedling soil treatment, and sulfonylurea herbicides can not be used in this kind of vegetable field in the previous crop, and acetochlor cannot be used in spinach.

2. Liliaceae, root vegetables, potato vegetables.

For example, leeks, garlic, green onions, onions, lilies, garlic, carrots, kohlrabi, potatoes, ginger, yams, etc. Leeks have a short growth period, frequent harvesting, and eat leaves, try not to use herbicides, and if necessary, you can choose to kill the slightly toxic herbicide Guoer, and spray the old leeks after harvesting.

Garlic, lily, potato, ginger, yam has a long growth period, and is mainly edible bulbs and tubers, (garlic edible garlic moss) can be soil treatment in the early growth stage or stem and leaf treatment in the early post-emergence stage, you can use fruit, garlic grass ether, vegetable Zhuang No. 2, etc. Green garlic, green onions, and onions have a short growth period, and can only be used with contact soil treatment agents; Radish and carrot can be treated with herbicides with poor conductivity, such as weeding.

3. Nightshade vegetables.

For example, eggplant, tomato, pepper and other vegetables should not use stem and leaf treatment agents, and before transplanting, you can choose to use contact soil treatment agents such as Ruoer, oxazil or vegetable Zhuang No. 2 and dilometin with a slight systemic conduction effect.

For example, cucumber, pumpkin, winter melon, loofah, vegetable melon, bitter gourd, bergamot, horn gourd, etc. It is strictly forbidden to use acetochlor in this kind of vegetables, and it is advisable to use herbicide, Guoer, and dioxapyrin for soil treatment after sowing.

5. Legumes and vegetables.

For example, kidney beans, cowpeas, raw edamame, peas, broad beans, lentils, etc. There are many herbicides suitable for vegetable applications, but soil treatment herbicides are still the first choice, such as dilodiamine, vegetable Zhuang No. 1, dioxazim and other post-sowing pre-seedling soil treatments.

6. Aquatic vegetables.

For example, lotus root, cocoon white, mushrooms, etc. Try not to use herbicides for aquatic vegetables, and if necessary, you can choose low-toxicity Lianzhuang No. 1, grass buster, etc.

7. Special vegetables.

For example, asparagus, burdock, lettuce, artichokes, ginger, camellia, maran, chrysanthemum brain, etc. Fruit can be used for soil treatment after sowing and before budding or before transplanting.
