In the process of agricultural planting, it is not uncommon to use the wrong herbicide, that is to say, the herbicide of a certain crop is used on another crop, I don't know how many farmers have experienced, today, the little helper received a message from a friend, he was in the control of weeds in the wheat field some time ago, accidentally used the herbicide in the corn field, and sprayed nicosulfuron as a wheat herbicide, resulting in the wheat has not fully recovered.
The above similar situation, I believe that many farmers have encountered, whether it is wheat, corn or other crops will appear, since it has been beaten, everyone is most concerned about how to remedy the problem, the following little helper to tell you.
First of all, if it is found in a timely manner, it is not long after it has just been sprayed or in the process of spraying, and the wrong situation is found, quickly find a clean spraying bucket and spray water in time, on the one hand, dilute the concentration of the liquid medicine with water to reduce the degree of pesticide damage, on the other hand, wash away the liquid medicine that has not been absorbed on the leaves, reduce the dose of absorption, and achieve the purpose of reducing the pesticide damage.
Secondly, if sprayed with water or found late, the field crops have been damaged, according to the severity of the pesticide damage to remedy, when the pesticide damage is relatively light, such as only the leaf tip is dry, the root system and stem are normal, you can spray some brassinolide, gibberellin or foliar fertilizer to alleviate (can also be compounded), in general, the crop can recover almost the same.
However, if the pesticide damage is more serious, the leaves and stems are dry, and the dead roots appear, in this case, there is no way to remedy, either wait for the end of the crop and plant the next crop, or directly destroy the seed, you can plant some vegetables with a short growth period, and it is gratifying to save some losses.
In addition, you may have heard of the antidote, propaganda can have a good effect on herbicide damage, for the antidote, we should be cautious, the first look at its ingredients, it may be brassinolide, gibberellin or other growth regulators, but the label of the antidote agent, second, if the herbicide damage can be advertised, then it should be noted, it may be a lie, because the serious situation of the drug damage (the root has died), there is no agent to alleviate.
Finally, I hope that in the process of spraying herbicides, we must see clearly before spraying, some older farmers may not be literate, you can consult your family or pesticide store people, unsure of the situation, do not spray at will.
That's all for the content of the wrong use of herbicides, I hope it can bring you some help, and of course I hope you don't use it.

This ingredient is acetochlor, but don't be afraid, as long as the pesticide use is reasonable and compliant, then there will be basically no residue in this ingredient, which is the conclusion of the test.
-
Even if there are ingredients in the herbicide that affect the stubble of wheat, after several months of relief, the alkaline components in the liquid medicine and the acidic components in the soil are combined and decomposed again, and the residue of the liquid medicine can no longer affect the wheat.
-
Corn ** turbulence, many farmers choose to plant other crops, so for soybeans, green storage corn, peanuts and other crop crops how to use medicine, do a tidying, absolutely dry goods, you can collect the overall principle of pesticide weeding, under the premise of crop safety, effectively prevent weed hazards, according to the crop selection of appropriate herbicide varieties and application methods, according to the soil type, sandy loam, light alkaline soil, meadow soil, loam, black loam, etc., and soil organic matter content to determine the correct dosage of herbicides, Depending on climatic conditions, soil moisture or temperature, determine the correct dosage of herbicides.

Summary. Hello, I am glad to answer for you that corn field herbicides have an impact on wheat, because wheat and corn are not the same plant, different plant types, different fruit types, so corn field herbicides will cause the leaves of wheat to dry up and yellow, and in severe cases, it will wilt and die, and it needs to be treated immediately.
Hello, I am glad to answer for you that corn field herbicides have an impact on wheat, because wheat and corn are not the same plant, different plant types, different fruit types, so corn field herbicides will cause the leaves of wheat to dry up and yellow, and in severe cases, it will wilt and die, and it needs to be treated immediately.
Most of the components of corn post-emergence herbicides are nicosulfuron, which has no residual pesticide damage to wheat, garlic, alfalfa, potato, soybean and other crops, but is harmful to crops such as cabbage, sugar beet, spinach, cucumber, sunflower and oil sunflower. After nicosulfuron is used in corn fields, wheat needs to be planted at least 8 months apart, soybeans, cotton, peas 10 months apart, rice and peanuts 12 months apart, and vegetables 18 months apart. 1. Does corn post-emergence herbicides have an effect on stubble 1. Most of the components of corn post-emergence herbicides are nicosulfuron.
If the crop is wheat, garlic, alfalfa, potato, soybean and other crops, there will be no residual pesticide damage, but when the crop is cabbage, sugar beet, spinach, cucumber, sunflower and oil sunflower and other crops, it will produce certain pesticide damage. Therefore, before planting, the pesticide damage test of related crops should be done first, and then planting should be carried out after confirming that there will be no pesticide damage to the subsequent crops. 2. The half-life of nicosulfuron in the soil is days, and after use, it takes at least 8 months to plant wheat, 10 months to plant soybeans, cotton, peas, rice, peanuts to plant 12 months, and vegetables and other crops to be planted at 18 months.
2. How to spray the herbicide correctly after corn seedlings 1. It is advisable to spray the herbicide after corn seedlings at the 3-5 leaf stage and weeds at the 3-5 leaf stage and weeds from 2 leaves and 1 heart to 4 leaves and 1 heart. At this time, the weeds in the field have basically come out, and there is a certain area of pesticides, and at the same time, the maize seedlings have high drug resistance and are not prone to pesticide damage. 2. Spraying post-emergence herbicides should be done at a temperature of 15-25, a relative humidity of more than 65% and a wind speed of less than 4ms.
Under normal circumstances, choose to spray after 6 o'clock in the evening, when the temperature is lower, the humidity is high, and the residence time of the liquid medicine on the leaf surface of the weeds is longer, which can allow the weeds to fully absorb the liquid medicine, and will not have much impact on the concentration of the liquid medicine due to high temperature, thus causing pesticide damage to corn. 3. At present, most of the corn post-emergence herbicides are composed of nicosulfuron, and sweet corn or popping corn is sensitive to the drug and should not be used. 4. When corn is treated with organophosphate agents, it is more sensitive to nicosulfuron, so the two need to be used at an interval (the time interval is about 7 days).
5. When preparing the pharmaceutical liquid, use secondary dilution. That is, first dilute the agent or powder with a small amount of water, and then add the remaining water and stir well.

Stem and leaf treatment agents such as 2-methyltetrachloride, butyl ester, fast killing, husper, and letharon basically have no effect, and if dicamba and other herbicides with a long residual period are used, they generally have an effect. Nicosulfuron is used improperly, and the heart leaves turn yellow and lose green after 3-4 days of application, and other leaves turn yellow in turn when it is severe.
Especially before the 2nd leaf stage or after the 6th leaf stage of maize, the use of nicosulfuron is easy to produce pesticide damage. The corn is the strongest resistance to nicosulfuron at the 3 5 leaf stage, and the drug is the safest at this time, and the general application time is after 5 pm. After the 6-leaf stage of corn, the drug should be sprayed directionally to avoid the liquid coming into contact with the corn heart leaves.
The chlorophyll of corn leaves is damaged, and white spots and dryness appear on the leaves, and the whole plant is severely whitened. Whitening of corn leaves (fading but not drying up in the early stage), whitening will affect photosynthesis, and will also have a more obvious inhibition effect on the growth of corn, and the larger the dosage, the more serious the pesticide damage.

Corn field herbicides have an impact on wheat, will cause the leaf tips of the seedlings to dry up and yellow, in serious cases, it will wilt and lodging, after the use of corn field herbicides on wheat, it is necessary to immediately spray water to dilute the concentration of the solution, and to apply brassin, gibberellin or foliar fertilizer to the wheat to reduce the damage.
Corn field herbicides have an impact on wheat, because wheat and corn are not the same plant, different plant types, and different fruit types, so corn field herbicides will cause the leaves of wheat to dry up and yellow, and in severe cases, it will wilt and die, and need to be treated immediately.
When breeding wheat, if it is sprayed with herbicide in the corn field, it is necessary to immediately pour a large amount of water into the field to dilute the concentration of the solution, and can wash off the liquid medicine that has not been absorbed on the wheat branches and leaves, maintain the normal growth of the plant, and avoid its death.
After spraying wheat with herbicides in corn fields, if the plant has pesticide damage, it should be sprayed with placenta, gibberellin or foliar fertilizer to alleviate the effect and achieve the purpose of reducing pesticide damage, and to apply phosphorus and potassium fertilizer to wheat to promote its vigorous growth.
When breeding wheat, it is necessary to spray herbicides once before the emergence of plants to avoid weeds and plants robbing nutrients, promote the healthy growth of wheat, and after wheat emerges, a second weeding is required, and it should be noted that high concentrations of herbicides can not be used.

Summary. Here for you to find out the way to alleviate the pesticide damage of cornAfter the occurrence of pesticide damage of corn, the remedial measures taken are mainly to improve the growth conditions of crops, promote the growth of crops, and enhance their resistance to stress, such as loosening the soil, increasing ground temperature and soil aeration. Depending on the growth of the crop, apply some fast-acting nitrogen, phosphorus, potassium or other micro-fertilizers.
You can also spray some plant growth regulators to promote the growth of the root system. However, it must be based on the needs of the crop and cannot be applied arbitrarily, otherwise it will be counterproductive. If there is standing water on the ground, it should be removed as soon as possible; If pests and diseases occur, they should be controlled as soon as possible.
In short, as long as the measures are conducive to the growth and development of crops, they are conducive to alleviating pesticide damage and reducing corn loss.
Your question has been received, it will take a little time to type, please wait a while, please don't end the consultation, you can also provide more effective information, so that I can answer for you more coarsely and dry.

If a non-selective herbicide containing glyphosate is used in the previous corn, it may have a negative impact on the vegetables that are planted next, as these herbicides may remain in the soil and be left behind. Therefore, it is recommended that you choose vegetables that do not cross-interact with glyphosate. In general, the following vegetables are more tolerant to herbicides:
1.Pleurotus eryngii, shiitake mushrooms and other fungal vegetables 2Green onions, onions, ginger, garlic and other seasoning vegetables 3
Pumpkin, zucchini, cucumber, eggplant and other fruit vegetables 4However, please note that even if these vegetables are relatively tolerant, they should be cleaned and disinfected. At the same time, if the original soil contains chemical fertilizers, organic fertilizers, etc., it is recommended to apply sufficient compost before the next crop planting to help degrade the pesticide residues accumulated in the soil.

Post-emergence herbicides for maize may have an effect on the next crop of wheat.
It depends on the residue period of the specific herbicide.
For example, atrazine has an effect on the next crop of wheat.
Atrazine in the soil residue period:
1. Atrazine will generally remain in the soil for about 6 months, because the residue time is relatively long, so after the application of atrazine, it usually takes an interval of time before the next crop can be planted, so as not to cause adverse effects.
2. After the application of pesticides, it generally takes 24 months to plant beans, peanuts, tobacco, alfalfa, sugar beets, rape, flax and other crops, and after 40 months, cucumbers and other crops can be planted.
3. Atrazine is a selective systemic conduction type of nitrogen benzene pre-seedling and post-seedling herbicides, which will be absorbed by the root system after spraying and conducted to the meristem and leaves of plants, hindering the ability of weeds to photosynthesize and promoting the early death of weeds.
Effect of atrazine on post-crop crops.
1. Whether atrazine has an impact on the later crops needs to be determined according to the type and dosage of crops, for example, in the last crop, if the active ingredient of atrazine per hectare exceeds 1000ml, it will cause relatively large damage to buckwheat, cucumber, sugar beet, cabbage, millet, rice and other crops, because the resistance of these crops to atrazine is relatively weak.
2. Potatoes, sunflowers, eggplants, tomatoes, cabbage, catkins, tobacco, broad beans, peas and other crops with medium resistance to atrazine are generally easy to cause different degrees of impact. It should be noted that because the resistance of rice cavity panicle to atrazine is very weak, so when raising seedlings, it is not possible to choose the soil that has applied Atrazine to raise seedlings, even if it is 1 to 2 years apart, it is not recommended to use it to avoid pesticide damage.
3. However, when the dosage per mu of atrazine is 350ml, it generally has no effect on corn, sorghum and other crops.
