What should I do if herbicides cause frequent damage?

First of all, we have to find the cause, only by finding the cause can we better solve the problem, the cause is not found to deal with blindly, then it is like a headless fly flying around. Now we have purchased some pesticides, or purchased some herbicides, the properties and safety of the herbicide itself are very poor, or it is not up to standard, so we are prone to pesticide damage. When we choose pesticides, we must find regular and qualified manufacturers or shops to buy pesticides.

Some pesticide formulations are unreasonable or there are illegally added ingredients, so it is also easy to cause pesticide damage. There are some unscrupulous traders or some manufacturers who are doing experiments, negligence when doing matching, or failure to meet the relevant standards, illegal addition or a certain substance content is too high, and the formula is problematic, so the damage to crops is often great, so when we buy pesticides back, we must make a comparison to see if it causes certain damage to crops, and if it appears, it should be replaced in time. <>

If you don't use the right method, then it's easy to get critical. If you use it in the wrong way, it will be a big deal, such as mixing or misuse, then it will lead to problems. Different pesticides will have different effects on some crops, for example, we all know very well that glyphosate cannot be sprayed on wheat, if we use glyphosate to spray wheat, it will be over, and pesticide damage will definitely occur.

The concentration should also be noted that if the concentration is too high, then it will also cause some damage to the crops. It's very simple, on the instructions for the use of pesticides is 1:100, and the result is 1:

The concentration of 50 is twice as high, so that the crops cannot withstand this concentration, and there will naturally be yellowing or other problems, so it is necessary to reflect on which link is the problem and solve it in time.

There should be a very good planting, and the pest should be removed regularly, so that it can be solved.

The use of these herbicides should be prohibited, and when buying herbicides, you must go to a regular place to buy them and use them in the correct way.

The dosage should be reduced, ventilation should be strengthened, and watering should be done so that the damage to the plant can be minimized.

Weeds compete with crops not only for water, fertilizer, and nutrients in the subsoil, but also for the space, heat, light, and other resources needed for soil growth. As we all know, brassinol is a plant growth regulator that can rapidly improve the quality of agricultural products and greatly increase crop yields.

Glyphosate has a strong internal absorption conductivity. By inhibiting the phosphate structure in plants, protein synthesis is severely disturbed, leading to drug damage in cultures. Methampheliurea is relatively stable and has a long-term residual effect, which directly affects the planting of subsequent sensitive crops.

After the application of brassinate, the internal hormonal action of the culture can be harmonized, the metabolism can be promoted, the function of amino acid synthesis can be restored, and the normal growth can be restored.

<> herbicide drops24 are safe for wheat, barley, corn and sorghum, but very sensitive to dicots and cotton. After spraying 24 drops on cotton plants and leaves, they pass through the stratum corneum and cell membranes and are finally delivered to the site, which has different effects on the synthesis of nucleic acids and proteins at different sites. The application of brassinol can not only reduce the absorption of herbicides in plants, but also increase the chlorine content in plants, so as to achieve a better effect of mitigating herbicide damage.

The effect of taking the medicine in the afternoon is better than in the morning, because the humidity in the field is still high when the spray is sprayed in the morning, and the medicine on the leaves easily condenses into water droplets. In addition, as the temperature continues to rise in the morning, all weeds are relatively dry in the afternoon after exposure in the morning and noon. Spraying herbicides at this time allows the weeds to absorb the liquid drug more quickly, so the herbicide can act as a stronger herbicide.

It is more advisable to dry the dew on the leaves at 9-10 a.m. or before the leaves set at 4-6 p.m., so that weeds can have more contact with and absorb the solution. When herbicides are used for weeds in chemical fields, the length of herbicide spraying time directly affects the effect of sprayed weeds. When weeds germinate, we can spray herbicides in the field, and the drug activity and herbicides will be greatly reduced due to long-term degradation of the drug.

After such a situation, you can rinse with water, and then you can also spray the diseased location several times in a row, and then you also need to strengthen photosynthesis, and you should pay attention to supplementing fertilizer, and then you also need to kill insects in time.

You can add more soil or add more water, which can play a certain role in dilution, or add some other chemicals, which can also be relieved and remedied.

You can understand the way to remedy, and at the same time, you can reduce the harm by alleviating the dosage of the agent, and you can spray more water to remove part of the agent.

How to prevent and control the pesticide damage caused by herbicides? When stems and plant leaves are damaged by herbicides, a sprayer can be quickly used to continuously spray the affected plants with a watery herbicide. It inhibits photosynthesis, which is mainly absorbed by the roots of plants, transmitted to the ground, and active in the presence of light.

The symptoms of product damage are similar to those of triazine, first with yellowing of the leaf tips and leaf tips, followed by two to three FIMs to eliminate or reduce the relative safety of plant amine herbicides for crops.

Due to excessive dosage or environmental conditions without herbicides, after the herbicide appears, sufficient irrigation should be carried out to reduce the concentration of herbicides in the crop, play a role in alleviation, and timely apply fertilizer, spray plant growth regulators, play a role in promoting the recovery of growth, and appropriate cultivation and pine stability, corresponding measures should be taken in different situations. Treatment method: After sowing, the herbicide alkali damage occurs, and the nature of the herbicide itself.

For example, security.

The above measures are specific measures to prevent herbicide damage, pesticides are not easy to maintain after ground spraying, and will basically not produce drug damage at the next harvest, and pre-sowing herbicides are not suitable for crops with underground rhizomes as income, but herbicides with stems and leaves as productive and easily degradable substances, such as imidazole ethyl niacin and chlorsulfuronmethyl and other long-term residual herbicides cause damage to sensitive crops at low residue concentrations; Overuse, misuse and mixing of herbicides and poor selection of additives can cause harm to drugs; The application deadline is incorrect.

Once the herbicide is applied, the drug is compromised. In the case of herbicide damage, we need to take a different approach. We have taken a look at the common treatment methods for relieving herb damage when it occurs.

When white spots appear on the leaves, it provides an important guarantee for the development of seed planting. But sometimes herbicides can cause significant damage to crops. What causes damage from herbicides?

How herbicides harm the leaves and turn white on top of the real leaves. Average and loose soil. According to the growing season, the number of tillage and soil loosening should be appropriately increased.
