Can herbicides be sprinkled directly in the soil

No. There are many kinds of herbicides, there are different ways to use different weeds, and there are different ways to use them according to different seasons.

Herbicide refers to a type of substance that can completely or selectively kill weeds, also known as herbicides, to eliminate or inhibit plant growth. Among them, sodium chlorate, borax, arsenate and trichloroacetic acid have a dead effect on any kind of plants, and their effects are affected by three factors: herbicides, plants and environmental conditions. According to the function, it is divided into incidal and selective herbicides, and most of the selective herbicides, especially nitrophenol, chlorophenol, and carbamate derivatives, are effective.

The development of herbicides in the world has gradually stabilized, mainly developing varieties with high efficiency, low toxicity, broad spectrum and low dosage, and disposable treatment agents with little environmental pollution have gradually become the mainstream.

The commonly used varieties are organic compounds, which can be widely used to control weeds, shrubs, trees and other harmful plants in farmland, orchards, flower nurseries, grasslands and non-arable land, railway lines, rivers, reservoirs, warehouses and other places.

There are many kinds of herbicides, there are different ways to use different weeds, and there are different ways to use them according to different seasons.

The removal of pesticide residues in the soil can be carried out according to the chemical composition of the soil pesticide residues, the saturation degree of the soil and the characteristics of the soil, the type of crop and its cultivation technology, and other factors. The following measures are often adopted in production practice:

1) Embedded activated carbon to reduce the activity of sulfuron or fuuron in the soil.

2) Inoculation with certain microorganisms to promote the decomposition of herbicides such as chloramid, dicamba and herbicides in the soil.

3) Pesticide degrading bacteria are applied to degrade the residual pesticides in the soil.

4) Apply a large amount of organic fertilizer, plant residues, garbage compost and green manure to reduce the toxicity of residual pesticides.

5) Use chemical additives to change the adsorption, absorption, migration, leaching, volatilization, diffusion and degradation of pesticides to reduce the residue and accumulation of pesticides in the soil.

6) Selecting drug-resistant crops or replanting cash crops can prevent toxic residual pesticides from entering the food chain.

7) Tillage turns plant residues into the soil to loosen and aerate the soil, enhance water infiltration, and promote pesticide degradation.

8) Controlling soil moisture through irrigation can create optimal water vapor conditions for microorganisms to degrade pesticides. Herbicides are washed off the surface of the crop's root system, thus ensuring its normal growth.

At present, most of the herbicides used by farmers and farm contractors are chemical synthetic agents, which themselves contain certain toxins, and when farmers spray weeds on the ground, their chemical toxins need a certain amount of time to spread and volatilize in the air and soil. Therefore, in addition to sunlight exposure and volatilization, the most rapid degradation of toxins in the soil should be high-temperature fire roasting, which is not difficult to implement in a small area, while a large area can only be flooded soil for a long time; By the way, there are many biological herbicides on the market, but the cost of using such herbicides is more than one-third higher than that of chemical herbicides, and many farmers have to use chemical herbicides to control weeds in order to save money!

1.Herbicide damage is manifested as inhibition of crop growth and malnutrition.

2.It disrupts the ecological balance of farmland and leads to increased pest resistance.

Herbicide residues in the soil have a big impact:

1.The amount and concentration of herbicides are large, so there will be residues after use.

2.The herbicide is used in the wrong way, mixed or not used according to the actual situation, which may cause residues in the soil

Eliminate herbicides that remain in the soil Method:

1.Before planting crops, the soil should be turned up.

The question is that the vegetables that have been planted grow at present, do not grow roots, and then the yellow hair dies.

On my side, I poured herbicide into the vegetable field without knowing that the well had been sprayed.

How many ways are there to remove herbicide residues?

1. "Bihu": "Bihu" comes from plant seeds, which is not synthesized but processed by physical methods, and contains 8 kinds of plant endogenous hormones, 11 kinds of plant catalytic balance components, 20 kinds of amino acids and anti-stress inducers, etc., which is a natural functional plant nutrient and strengthening agent. How to use:

Seed dressing, soaking, root irrigation, and spraying can be used, as early as possible. For example, to control soil-borne disease nematodes, root irrigation has the best effect, and there is an accumulation effect after repeated use.

2. Chitin (4% Poshengin): chitin applied to the soil is the medium of actinomycetes, actinomycetes will multiply rapidly when they get nutrients, and grass can induce plants to synthesize chitinase, chitosanase, glucanase, plant protection, lignin, peroxidase, polyphenol oxidase, isoflavones, chitinase, etc., which can promote the growth and development of crops. How to use:

It can be used as early as possible, such as seed dressing, soaking, root irrigation, spraying, etc.

3. "Yihu": "Yihu" (Bacillus subtilis) is a functional plant nutrient from the plant, also known as a microecological agent. Production practice has proved that the dominant bacterial community accounting for about 40% of the total microbial volume of the plant can be provided for plants after 30 days of seed dressing, root dipping, and 15 days after spraying stems and leaves.

Similarly, "Yihu" can be used for seed dressing, soaking, and spraying.

How do you get rid of herbicides left in the soil? I don't think the herbicide needs to be removed, it automatically evaporates after more than three months.

Eliminate herbicides remaining in the soil Method: Before planting jujubes, the soil should be turned before the tomb. 2.

Irrigate the field and drain the residual shaku-rock weed. , which can dilute pesticide residues. 3.

Quicklime is spread and raked to break down the residual herbicide in the soil. Note: The herbicide should be used in an appropriate amount, and it should be prepared according to the instructions, and the dosage should not be increased casually.

You can also consult some agricultural experts to achieve scientific farming.

Summary. Hello! Glad to be able to answer your questions.

There are many ways to eliminate the herbicide remaining in the soil, such as: (1) washing method: wash the soil with a large amount of water to dissolve the residual herbicide, and then discharge the soil.

2) Suction method: Suction device is used to suck out the residual herbicide, and then discharge the soil. (3) Adsorption method:

Adsorbents, such as pulverized coal, activated carbon, etc., are used to adsorb the residual herbicide and then discharge it from the soil. (4) Phytoremediation: specific plants, such as soybeans, amaranth, etc., are used to absorb the residual herbicides and then discharge them from the soil.

In addition, other measures can be taken, such as controlling pests and diseases in key halls, improving soil quality, etc., to effectively suppress the effects of residues.

Please refer to a few anti-residual reducers.

The common residue detoxifiers of the Plum group are: sodium hydroxide (NaOH), sodium sulfate (Na2SO4), sodium chloride (NaCl), ammonium sulfate (NH4HSO4), calcium sulfate (CASO4), copper sulfate (CuSO4), ammonium chloride (NH4Cl), iron chloride (FeCl3), calcium chloride (CaCl2), etc. These reducers can effectively remove residue modification, reduce pollution, and improve product quality.

In addition, nuclear fibers can also use adsorbents such as activated carbon and activated silicon to solve the residual problem.

Hello dear, glad to answer for you! The methods to eliminate the herbicides remaining in the soil are: 1. Microbial degradation method:

Specific microorganisms, such as bacteria, fungi, etc., are used to break down herbicides into harmless substances. This method requires the addition of specific microorganisms to the soil to facilitate the decomposition process. 2. Water retention and ventilation:

Herbicides prefer to survive in moist environments, so keeping the soil aerated and water-retaining can reduce herbicide residues. This can be achieved through means such as mulching, shading, and moisture management. 3. Phytoremediation method:

Plant some herb-resistant plants, such as soybeans, sugar beets, etc., to absorb herbicides from the soil and then metabolize them into harmless substances. 4. Activated carbon adsorption mold rolling: use activated carbon to adsorb the herbicide in the soil, and then remove it.

This method requires the addition of the right amount of activated carbon to the soil.

Hello pro is happy to <> your questions

Removing residual herbicides from the soil can usually be achieved by washing with water or air. 1.Wash:

If the soil contains residual herbicides, the residual herbicides can be washed away by washing, and if the soil contains a large number of harmful substances, alkaline water (alkaline water or high-strength alkaline solution) can be used to discuss the situation. 2.Air scrubbing:

Compressed air is used to disperse residual herbicides from the soil. The number of washes depends on the amount and nature of the hazardous substance. If the content of harmful substances is large or the contamination point is large, Paison can choose to wash it multiple times to ensure that all residual herbicides are washed.
