What herbicide has no effect on choy sum?

Herbicides are already an indispensable tool in modern farmland, but because different fruit trees are more sensitive to herbicides, the same herbicide cannot be used on different fruit trees.

1. Herbicides that cannot be used in orchards.

1. Peach Tree Orchard - Chlorsulfuron.

For example, when chlorsulfuron is applied in peach orchards, the residual effect period of the drug is long, and the agent is dissolved into the ground and absorbed by the root system, causing necrosis of the root system of peach trees, making it grow poorly, and seriously causing the destruction of the garden.

2. Atrazine-peach.

Atrazine is sensitive to peaches and is prone to pesticide damage, especially the herbicide cannot be used on peach seedlings and young peach trees.

3. Simazine-seedlings.

Simazine is applied on fruit tree nurseries and seedlings and is also susceptible to pesticide damage. In the orchard where Sima zine is applied, it is not advisable to interplant sensitive crops such as beans and melons.

4. Glyphosate-banana seedlings.

Banana seedlings are sensitive to glyphosate, so be careful when spraying, and prevent drifting and contact with nearby branches and leaves of pears, citrus, grapes, etc., as well as the trunk of young trees, to avoid its pesticide damage.

5. Glyphosate - peach, pear, plum orchard.

The use of glyphosate for weeding in peach, pear and plum orchards not only has a great impact on the yield and quality of peach, pear, plum and other fruit trees, but also easily induces the occurrence of peach, pear and plum gum disease and accelerates senescence and death. After the peach, pear and plum orchards that have just planted young trees use glyphosate to control weeds, their growth is stunted, and even they die, and they cannot survive.

6. Diuron - grapes, pineapples.

Diuron grapes planted in sandy soil and gravelly soil should not be applied, otherwise the pesticide damage will be more serious;

In the application of pineapple orchard, due to the long residual effect period, after repeated use of diuron, there are residues in the rhizomes and leaves of pineapple, so other types of herbicides should be selected or used alternately with other herbicides to minimize the occurrence of pesticide damage.

Bath agent will have a certain impact on cabbage, but we must pay attention to any one when choosing, but we must use the dosage and be careful not to overdo it.

Weeding with herbicides. The method is: 750 ml of 10% glyphosate water solution, or 150 200 ml of 20% paraquat water solution, or 50 ml of 41% glyphosate water solution, or 150 grams of 50% glyphosate sodium salt wettable powder per mu, add 50 liters of water, and spray on sunny days.

Many herbicides have an effect on vegetable plants.

The water can be diluted with some tusin or glyphosate, and sprayed 100 times.

Pass with weeding. It is also called Shi Tian Bu. Pre-emergence closure or early post-emergence spraying. on barnyard grass. Portulaca oleracea. Gray cabbage is efficient. Safe for a wide variety of vegetables. Please try it.

This is the case you are talking about.

What herbicides have no effect on crops?

In general, a certain herbicide only has no effect on a certain type or a certain type of crop, so it depends on what kind of crop you have to know what herbicide to use, but herbicides can have an impact on the land that has been planted in the future.

Hello, herbicides, only on the grass on the ground, has an effect, on the cabbage, is not affected, sprayed, you have to wait for more than half a month to pick this cabbage to eat.

What herbicide has no effect on herbicides, in fact, the grass you hit should be too vegetable gold has no effect, if there is an effect, you put it in water to soak it.

General herbicides have an effect on vegetables, but spray for a longer time and then pick, which is better.

What herbicides have no effect on the cuisine, I think there are many herbicides that have no effect on the cabbage, after all, our Chinese science is also very strong.

Generally speaking. Herbicides have an effect.

You must use it in advance.

Avoid affecting yields.

Herbicides have an effect on both vegetable plants.

It can be avoided when used, or weeded in a physical way.

Now there is a special sale of pure grass, and he hits the water on the choy sum, which has no effect on the choy sum.

Any herbicide you have to get will have an impact on the choy sum.

Herbicides generally have no effect on the work.

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!

Herbicides are chosen so as not to harm crops and crops. Several common non-harmful herbicides are:1

Glyphosate herbicide: It is a commonly used choice of modular rubber herbicide, which is basically non-toxic to most crops, has a good control effect on most weeds, and is also safer for humans and animals. Commonly used commodities include grass loss, glyphosate, etc.

2.Lysochlor herbicide: It is a cyclohexaneamide herbicide, which can selectively kill most broadleaf weeds and some grassy weeds, and is safe for crops.

The trade names include Spirachlor, Dimethoate, etc. 3.Dimethyltetrachlorobenzene pound ester herbicide:

Such as MCPA, 2,4-D, etc., have a wide range of herbicidal spectrum and are safe for most crops. Common commodities include bad grass, straw stacks, etc. 4.

Niacin herbicides: such as sodium niacinate, nicotinate, etc., are safe for most crops and fruits, and can control a variety of broad-leaved weeds. Products such as nicotinate, etc.

5.Sulfonylurea herbicides: such as glyphosate, fluoroxafen, etc., have good herbicidal effect and high selectivity, and are extremely safe for many crops, and are a class of herbicides widely used in recent years.

In addition, there are some biological herbicides, mechanical weeding and ecological weeding methods, such as black grass feed, insect repellent control, mechanical weeding machine, potato vine weeding machine, etc., these methods are pollution-free, safe for the environment and human body, and belong to the direction of green weeding. In general, choosing the right non-harmful herbicide, the right way to use it and the right weeding period can maximize the weed killing without harming the crops.

Herbicides are harmful to the ground if they are used too much, but it has decomposition, and there is no harm after a long time. If the herbicide is used too much, the grass is gone, the crops are gone, there is nothing, this depends on time to solve, if the herbicide is used too much, nothing will grow.

It takes a long time to detoxify, usually a month and two months, in this case, the crops of this season are gone, and the yield is extinct. This will have to wait until next season to plant it to be non-toxic, so we can't eat food that uses too much herbicide.

There is a situation that we have to pay attention to, including farmers, just say pesticides, not only herbicides, farmers must pass the decomposition period of pesticides, now the pesticide decomposition period on the market is generally after seven days, preferably two weeks, sprayed pesticides must be two weeks after the market. As long as the amount and period of herbicide are mastered, the herbicide components sprayed on the soil will gradually decompose, and the free presence in the soil will synthesize new inorganic salts and become nutrients for crops to absorb.

However, if the herbicide is used excessively, the herbicide will not have time to decompose, and the crop will absorb and accumulate the herbicide, and its biological tissue will be damaged to a certain extent, unable to synthesize some nutrients that it should have, resulting in the loss of some nutrients in the crop fruit. The excessive use of herbicides will also have a certain inhibitory effect on crops, affect the normal development and maturity of crops, and lead to hidden yield reduction or no harvest.

Will the food grown cause harm to the human body? Generally speaking, herbicides are used scientifically, and the food that grows is not harmful to the human body. Looking at the country's agriculture, it can be said that no pesticides do not farm, basically all crops are using pesticides, the use of herbicides is very common, as long as the dosage and use of herbicides are mastered, the crops themselves can metabolize pesticide residues, so farmers do not have to worry too much about this problem, the food grown will be safe.

Finally, the state is becoming more and more strict in the management of pesticides, has stopped the production of a number of highly toxic and highly polluting pesticides, and actively produces environmentally friendly, pesticide products with little impact on the environment, and the impact of pesticides on the environment will be smaller and smaller in the future.

Vegetable herbicide pesticide damage, is not harmful to the human body, because herbicides also have a strong toxin, although it can remove weeds, but it is also easy to be absorbed by vegetables, if you often eat a large number of vegetables with herbicides, then it is harmful to human health, especially for the stomach or liver, kidneys have relatively large damage, will cause chronic poisoning!

The specific harm is that if it is not used properly, it will cause acute poisoning, and then it will also bring great harm to the body, which will damage the nerves, and will also cause the death of the central nervous system, our immunity will be reduced, and we will often catch colds, dizziness, night sweats, insomnia, and memory will also decline.

If used incorrectly, it can damage our nerves, affect the central nervous system, which can lead to memory loss, insomnia, anemia, and in severe cases, possible poisoning.

The impact of herbicides on the human body is different, some are low toxicity, some are moderately toxic, the impact on people is basically not large, eating should not affect, or very small, because the principle of herbicides and insecticides is different, basically by affecting the formation of protein or nucleic acid of crops, so as to achieve the purpose of weeding, so the impact on people is basically nutritional insufficiency.

It will affect human health, but also affect the health of the respiratory tract, may cause human poisoning, may also cause loss of appetite, and will also harm the human digestive system, which are harmful to the human body.

Summary. A: There are two kinds of ah. Pyroxyflumethoxalin is a post-emergence selective herbicide, which has systemic conductivity, which is quickly absorbed and transported by weed leaves to the whole plant after stem and leaf treatment, resulting in weed death due to inhibition of meristems of stems and roots.

Its medicinal effect is fast, and the agent sprayed into the soil is easy to be absorbed by the roots, and it can also play a role in killing weeds. It has excellent control effect on annual and perennial grasses from post-seedling to tillering and early heading, especially for perennial stubborn grasses such as reed, white grass and dogtooth root. Highly safe for broadleaf crops.

It is also ineffective against broadleaf weeds such as broadleaf grass and sedge. The efficacy of pyroflumethoxalin is long, and one application basically controls the whole growth period and grass damage. The drug is reduced in the soil and has no effect on the planted crops.

The effect is stable at low temperatures. The difference between quinoxalin and pyrodioxalin.

There are still greens in the vegetable field, what herbicide is used to control the weeds without hurting the vegetables? l

1. Artificial hoeing is a more reliable method of Fang Hui, 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.
