What should I do if I miss the identification time limit due to crop herbicide pesticide damage?

Herbicide overdose and pesticide damage can be remedied by the following methods:

1. Water spraying: When it is clear that the spraying dose of herbicides is too large, it should be sprayed with water in time to remove foliar residues, reduce the concentration of herbicides in crops, and timely irrigate to promote the transpiration of wheat and reduce pesticide damage. Field irrigation water can also be used to continuously flush with fresh water, or combined with drainage to put lime and other methods to neutralize the acidic herbicides in the field and reduce the pesticide damage.

For the pesticide damage on the plant, the toxic residues on the plant can be washed away by sprinkler irrigation machinery or spraying equipment, and the poison attached to the leaves can be reduced.

2. Strengthen fertilizer and water management: when the pesticide damage is light, some leaves of crops appear brown spots, and the heart leaves are not dead, and some leaf losses can be compensated for by strengthening fertilizer and water management, and they can generally be recovered in a short time.

3. Spraying antidote or corresponding remedial agent: ferrous sulfate can reduce the pesticide damage of gram traces to wheat, and calcium polysulfide can make the residual simazine activity in the soil disappear. Due to the pesticide damage caused by auxin-type herbicides, gibberellin can be sprayed to reduce the pesticide damage; Due to the pesticide damage caused by contact herbicides, foliar fertilizer can be sprayed to promote the rapid recovery of crop growth, so as to relatively reduce the pesticide damage.

If the parties can not negotiate and resolve the issue of compensation for drug damages, they may mediate in accordance with the principle of voluntariness under the auspices of the agricultural administrative departments at or above the county level where the incident occurred. The mediation shall be concluded within 5 working days, and if mediation cannot be reached, the parties shall be informed to submit it to the consumer association, arbitration institution or judicial department for handling.

Generally speaking, the damage caused by the characteristics of the herbicide, if not very severe, can resume growth within a week, we are average"Turn a blind eye"，"Laissez-faire"。

For example, after the corn herbicide mesotrione, aminogatrione is treated with corn stems and leaves, due to the interference of photosynthesis in the meristem and leaves, white spots will appear on corn leaves, which is obviously a herbicide pesticide. However, this pesticide damage does not affect the growth and yield of crops, and can recover naturally within a week, so we do not need to take any measures against this pesticide damage.

On the contrary, if it is not the pesticide damage caused by the characteristics of the herbicide, but the misuse, misuse, or error in the way of use, or the pesticide damage caused by additional factors such as the natural environment, we must take corresponding emergency measures according to the degree of pesticide damage, so as to quickly restore the growth of crops and ensure that crop yields are not affected.

For example, after the above situation occurs after the pesticide damage, can not be recovered within a week, and the crop growth is obviously inhibited, the first thing we need to do is to use gibberellin plus herbicide antidotes, such as anti-pesticide Lingxian Yousu, etc., plus an appropriate amount of amino acid foliar fertilizer to spray the whole field of pesticide crops, repair the damaged crop cells, so that they can quickly resume growth. Depending on the extent of the damage, the drug can be used two to three times in a row.

There should also be medicinal residues in the crops.

Washing method. When the dosage of systemic herbicides such as herbicides is too large and causes pesticide damage, it should be immediately rinsed with water or sprayed to wash off the unabsorbed liquid on the crop and reduce the continued harm of the residual liquid to the crop. Generally, after washing 3 times, the town sees new leaves, and the lost green leaves begin to color, and the town recovers in 7 to 10 days.

Rinse with water. A clean sprayer can be used to infuse clean water and spray on medicated-treated plants several times in succession to remove or reduce herbicide residues on crops. It can also be sprayed with quicklime and sodium carbonate diluted water, which has a good effect on eliminating pesticide damage.

Turn over the ground as soon as possible, water more, it should not be a big problem, and the effect period of general pesticides does not exceed 3 months, so don't worry too much.

You can spray "foliar fertilizer" in time to solve it, such as "detoxification", "detoxification + antidote", "cloud lissein", "gibberellin", "920", fast-growing roots mixed with urea 50 grams of watering can, choose 1 kind each. The concentration of the first spray of "foliar fertilizer" must be light and not thick, because it is too thick and easy to cause fertilizer damage. Once every 5-7 days, 2-3 times in a row.

Normal growth can be restored.

There is no good way, only waiting.

The generic name of sencaojing is metsulfuron, which is a long-term residual herbicide of sulfonylurea with a residual effect of more than 2 years, and is not suitable for farmland weeding. Due to the long residual period of forest grass net, it takes 2-3 years or even longer to plant crops in fields where forest grass net is used. However, if you have a limited amount of herbicide left on the edge of the field due to rainfall, the residual effect period may be shorter.

That's all for my understanding of herbicide damage, including how to deal with these symptoms.

The pesticide damage is due to the high concentration of the agent, which can be destroyed by spraying potassium permanganate, and then spraying growth agents and other substances to relieve a series of problems caused by the pesticide damage.

Personally, I think that when herbicides produce pesticide damage, you can give crops, I feel that eating a high-protein nutrient solution at home, you reduce the toxic effect of pesticides on crops.

The harm caused by the herbicide is very small for us, it only acts on the grass. There may be some contamination on crops, but we will not come into direct contact with crop residues. After processing, the probability that the crops we eat will have herbicides on them is basically zero.

Glad for your question.

The requirements for the use of herbicides are generally stricter than insecticides and fungicides, and different herbicides have specified dosages and concentrations. The special drug for relieving herbicide damage is brassin, which can relieve the damage of herbicides. For example, brassinin can alleviate the damage of glyphosate, glyphosate has strong systemic conductivity, and by inhibiting the phosphate synthase in the plant, the protein synthesis is seriously disturbed, resulting in pesticide damage to crops.

The application of brassinin can accelerate the synthesis of amino acids in the body, make up for the amino acids lost due to pesticide damage, meet the needs of crop growth, thereby reducing pesticide damage until normal growth is restored, tillering is restarted, and young panicle differentiation is resumed. Brassin is a special drug for relieving herbicide damage, which can make up for the amino acids lost by glyphosate after the application of brassin, so as to reduce the pesticide damage until the plant returns to normal growth.

Please give it a thumbs up, dear.

Thank you. Questions.

How to solve the pesticide damage of the previous stubble, after the previous stubble is sprayed, when it comes to the next stubble, after planting the vegetables, the height is different, and it does not like to grow.

Brassin is a special drug for relieving herbicide damage, which can make up for the amino acids lost by glyphosate after the application of brassin, so as to reduce the pesticide damage until the plant returns to normal growth.

First, it is necessary to choose the herbicide varieties correctly, and it is best to experiment with unfamiliar varieties or varieties that have not been used in the local area. Second, it is necessary to persist in providing training and technical personnel to the peasants and to develop a professional contingent. The third is to use safety agents to prevent drug damage.

Fourth, the use of plant growth regulators, water and fertilizer and other measures to promote crop growth and reduce herbicide damage. Fifth, the use of ploughing, irrigation and soaking measures to eliminate the herbicide residues used in the previous stubble.

Herbicide damage refers to a series of abnormal phenomena caused by the inappropriate application of herbicides and the stunting of the normal physiological function or growth and development of crops. Acute drug damage has obvious symptoms in a few hours to 3 4 days after spraying, and it develops rapidly, such as burns, perforations, wilting, falling leaves, falling flowers, falling fruits, etc. Chronic pesticide damage caused obvious reactions after spraying for a long time, showing poor growth, leaf deformity, greening and yellowing, delayed ripening, poor flavor, and dissatisfied grains.
