Can herbicides break the roots at minus 1 degree?

In this case, of course, it should be in a state where it can be beaten, and herbicides work through absorption, so as long as it is a living grass, it can work.

In this case, the temperature is too low, so the effect of this herbicide is not very good, and once the temperature is low, it is not conducive to the growth of plants.

The minimum use temperature for herbicides is 5°C. Herbicide refers to the agent that can completely kill all weeds or selectively let weeds die, it is also known as herbicide, is used to eliminate or inhibit the growth of plants. When the temperature is more than ten degrees, it is better to apply herbicides (the effect can be better if the temperature is higher), and the temperature is low and prone to pesticide damage.

Only under the action of light and light, the leaves of the plant absorb the herbicide and conduct it to the roots, prompting the roots of its weeds to rot. Now the outside temperature is relatively low, the light and effect are poor, and the herbicide is difficult to be effective. So. It's best to wait until the beginning of spring next year before applying the medicine!

Summary. Hello dear, herbicides can rot tree roots if they are not mixed with water, and quickly kill tree roots. After using herbicides to promote the rot of tree roots, it may cause serious damage to the growth of crops, and it can only be planted after 2-3 years, acting on a variety of trees, and the use effect is better.

Lyphosate-triclopyropyro, which is made of glyphosate and trichloropyroacetic acid, is also a biocidal herbicide, mainly used to kill trees, poplars, willows, locust trees, vitex, wild wolfberry, humulus, creepers and other trees, with the advantages of fast weeding speed and thorough dead weeds, and is the best herbicide to kill all kinds of trees at present.

Hello, I have seen your question Ha Beibi is now manually replying to the content guess for you, but it takes a little time, please wait patiently, thank you Ha Fang Zhaoqin I am here to wish you a good Year of the Tiger

Hello dear, herbicides can rot tree roots if they are not mixed with water, and quickly kill tree roots. After the herbicide promotes the rot of tree roots, it may cause serious damage to the growth of crops, and it can be planted after 2-3 years. Chloropyritic chloropyropyro, which is compounded by glyphosate and trichloropyroacetic acid, is also a biocidal herbicide, mainly used to kill tree traces, small poplars, willows, locust trees, vitex, wild wolfberry, humulus, creeper and other trees, with the advantages of fast weeding speed, dead grass thoroughly, etc., is the best herbicide to kill all kinds of trees at present.

Pour the herbicide under the roots and the tree will not die. Most herbicides are used in prescribed dosages and methods to kill only certain species of weeds without harming crops, and are called selective herbicides.

There are two types of conventional application methods for herbicides:

Soil treatment, in which a herbicide is applied to the soil layer before and after crop sowing and planting and before weed germination, is called a pre-emergence herbicide.

Stem and leaf treatment, which is applied during the growth period of crops and weeds after germination, is called a post-bud herbicide. Appropriate herbicides and application methods must be selected according to the different crops, farmland types and weed communities, otherwise they will not only be ineffective, but will cause pesticide damage to crops. Cultivation management (fertilization, irrigation, crop rotation, etc.) and environmental conditions (temperature, humidity, soil type, etc.) have an impact on the efficacy of herbicides, and should be considered according to local conditions.

Usually in different fields or in different seasons of the weed community has great changes, often a single herbicide can not be effective, so two or more herbicides should be used successively or mixed to form a weed control system. Most herbicides are less toxic to humans and animals, so safety and environmental pollution are less of a concern. Fold this paragraph of pesticide hazards.

No, glufosinate ammonium is a broad-spectrum contact herbicide, the systemic effect is not strong, unlike glyphosate to kill roots, glufosinate ammonium kills leaves first, and can be conducted in the xylem of plants through plant transpiration, and its quick effect is between paraquat and glyphosate.

Glufosinate-ammonium physicochemical properties:

1. Properties: white crystals, with a slight smell.

2. Melting point: 210°C

3. Boiling point: at 760 mmHg

4. Flash point: 5. Vapor pressure: at 25°C

6. Solubility: The solubility in water is 1370g l(22), the solubility is low in general organic solvents, and it is stable to light.

Summary. Hello dear: After beating the bad herbicide, if the grass roots have been completely removed, and there is a certain time to wait for the grass roots to die, you can use a mulching herbicide for secondary weeding.

However, it is necessary to pay attention to the following points: confirm that the grass roots have completely died: the effect of the grass rot is to destroy the grass roots, but it takes time to wait for the grass roots to die, otherwise new grass roots will still grow.

Before using a mulch herbicide, it is necessary to confirm that the grass roots have died completely to avoid the regrowth of new grass roots. Choose the right mulch herbicide: Different mulch herbicides have different effects for different grass species and environments, and the right mulch herbicide needs to be selected according to the specific situation.

It is recommended to choose a mulch herbicide that has a specific effect on the target grass species to improve the herbicide effect. Pay attention to the method of use and dosage: The use of mulch herbicides needs to be used in accordance with the correct method and dosage to avoid problems such as waste or environmental pollution caused by excessive use.

At the same time, it is necessary to pay attention to safe use to avoid causing harm to the body. In short, after beating the herbicide, you can use a mulching herbicide for secondary weeding, but you need to pay attention to confirming that the grass roots have died, choosing the appropriate mulching herbicide, and the correct use method and dosage.

Today, I hit the grass on the grassless ground, when can I apply the mulching herbicide?

Hello dear: After beating the bad herbicide, if the grass roots have been completely removed, and there is a certain time to wait for the grass roots to die, you can use a mulching herbicide for secondary weeding. However, there are a few things to keep in mind:

Confirm that the grass roots have died completely: the effect of the rotten grass agent is to destroy the grass roots, but it takes time to wait for the grass roots to die. Before using a mulch herbicide, it is necessary to confirm that the grass roots have died completely to avoid the regrowth of new grass roots.

Choose the right mulch herbicide: Different mulch herbicides have different effects for different grass species and environments, and the right mulch herbicide needs to be selected according to the specific situation.

Do two herbicides need to be spaced.

Hello Kiss Before using a mulch herbicide, you need to confirm that the grass roots have died completely to avoid new grass roots from regrowing.

Glyphosate isopropylamine salt, which is a systemic type, non-selective herbicide. Through leaf absorption and conduction to the roots of weeds, the synthesis of some enzymes in the body is inhibited, so as to achieve the purpose of killing weeds and removing roots at the same time.

An expert in Shandong has studied one, which is used on consecutive sunny days, and what is killed is hit, and it will die when it is touched until the root rots.

Summary. Dear users, the rate of root rot depends on a variety of factors, including the type of plant, growth state, soil conditions, climate, etc. Generally speaking, it takes a certain amount of time for the root system to rot completely, usually from a few weeks to a few months.

When using the herbicide, it is necessary to make appropriate adjustments according to the growth state of the plant and the environmental conditions to achieve the best results. At the same time, it is also necessary to pay attention to safety when using rotten herbs to avoid harm to the human body and the environment. If you have more questions, you can always ask me.

Dear users, the rotten root speed of the rotten grass depends on a variety of factors, including the type of plant, growth state, soil conditions, climate, etc. Generally speaking, it takes a certain amount of time for the root system to rot completely, usually from a few weeks to a few months. When using the herbicide, it is necessary to make appropriate adjustments according to the growth state of the plant and the environmental conditions to achieve the best results.

Can you add, I don't quite understand it.

Dear users, the rate of root rot depends on a variety of factors, such as the type of grass, the growth state of the grass, the dosage and the ambient temperature. In general, it takes 2-4 weeks for the grass to completely rot the root system of the grass. When using the grass rot agent, it is recommended to use it according to the dosage on the instructions and use it during the vigorous growth period of the grass, so as to increase the rot rate of the grass roots.

At the same time, temperature is also an important factor affecting the speed of grass root rotting, the higher the temperature, the faster the grass root rotting rate. However, it should be noted that the rotten grass difference molding agent also has a certain impact on the Huanzhi Qingming Realm, and it is necessary to pay attention to protecting the surrounding plants and soil when using it.
