If there is a large area of herbicides, what is the responsibility and who bears it?

Generally speaking, only one agency in a province is responsible for this matter, and if there is no problem, everyone is not responsible, and the peasants will make trouble in vain. If there is a problem, the manufacturer should be fully responsible. In addition, you should pay attention to the technical problems of use, if it is involved, you will say that it is recommended to use according to the instruction manual on the back of the product, and do not say the usage recommended by yourself, otherwise it is improper use, and it is completely your responsibility.

Such problems are best resolved through legal means.

1. Contact the dealer and the factory to ask for reasonable compensation. It is best to pay.

2. Ask the dealer next door for advice, because of the competition, he will give you ideas.

3. It may involve illegal production and illegal operation, which is a criminal offense. Such a large area of pesticide damage is generally a product quality problem. If the dealer and the factory do not solve the problem, they can report to the Public Security Bureau. Pay attention to sample retention and forensics.

Good luck!

According to the "Pesticide Management Regulations", each pesticide production enterprise produces each pesticide commodity preparation, must have "three certificates" (pesticide registration certificate, production license and product standard certificate), if the "three certificates" are not complete, the pesticide is counterfeit and shoddy pesticides.

First of all, you can apply to the agricultural supervision department to determine whether the reduction in production is caused by drug damage.

Secondly, it is necessary to see that the pesticides sold by themselves do have certain flaws. According to the "Pesticide Management Regulations", a qualified domestic product, in addition to obtaining a pesticide registration certificate, pesticide production license or production approval documents and product implementation standard documents, the quality and label of the product must also be qualified. The label or instruction manual shall indicate the pesticide name, enterprise name, product batch number and pesticide registration certificate number or pesticide temporary registration certificate number, pesticide production license or pesticide production approval document number, product implementation standard number, as well as the active ingredient, content, quality, toxicity, use, application technology, application method, production date, expiration date and precautions of the pesticide.

The state implements a strict review system for pesticide labels, and the content of the label approved by the state shall not be modified by any producer or operator without authorization.

Inhibits the growth of crops in the current seasonExperiments were conducted on wheat, corn, soybeans and cotton at normal dosages. The results show that basically all herbicides have one thing in common compared to manual weeding, and that is reduced yield.

Inhibiting crops for 7-15 days in the current season reduces yields by more than 10%. Under weak seedlings, inverted seedlings or increased dose conditions, the yield is reduced by 20-30%. The experiment of the plant protection station in Heilongjiang Province showed that the herbicide reduced the yield of corn, soybean and rice; Tests by the Henan Provincial Institute for Drug Control have shown that the herbicide has reduced the yield of wheat, soybean and corn; The test results of the Shandong Provincial Plant Protection Station showed that the herbicide *** reduced the corn yield by 16%.

Residues affect the development of subsequent crops:The basic principle of herbicides is to inhibit acetyllactate synthase (ALS) in plants, which affects the synthesis of branched-chain amino acids. Herbicides are the most lethal to weeds in protecting crops.

But weeds are related to cultivations. For example, wheat growing in a canola field is a weed during the same suitable growing season. After harvesting wheat, soybeans or corn are planted, and the regenerated wheat is also a weed.

Because of the time gap, there are many difficulties for herbicides.

Because herbicides are targeted, weeds are relative to planted crops. When the so-called "weed" becomes a planted crop, the herbicide that remains in the soil still does not let it go. If the herbicide used on a crop is meant to kill the crop, then the crop will be haunted by demons and will not be able to grow properly or even cause severe crop failures.

Food, soil and groundwater contamination:The herbicides we use are mainly organophosphorus, which can remain in the soil for more than 36 months. According to surveys, 20-70% of commonly used herbicides will remain in the soil for a long time, causing contamination of soil, groundwater and even food.

Contaminated crops can also affect health when they enter the human body through the food chain.

Causing the land to become "cancerous":The "cancerous" of the land is the image of what people call the "cancer field", which is neither likely to change the crop, with low yields or no harvest at all. In Heilongjiang, Inner Mongolia, Jilin and other northeastern regions, due to long-term overuse of herbicides, large areas of "cancer fields" have emerged.

Although no "cancer zone" has been found in the Central Plains, there is a need to prevent the cumulative effects of long-term herbicide use. Once"Cancer field"The formation of agricultural production will suffer significant losses.

Inhibits the growth of crops in the current seasonUnder the normal dosage, experiments have been done on wheat, corn, soybeans, cotton, and other crops, and the results have found that basically all herbicides have ***, which is reduced compared with manual weeding.

Residues affect the development of crop stubble. The basis of the herbicide is to inhibit acetyllactate synthase (ALS) in plants to affect the synthesis of branched-chain amino acids.

Contamination of food, soil and groundwater. Because the chemical herbicides currently used are mainly organophosphorus, and the residual period of organophosphorus in the soil can generally be more than 36 months.

Third, herbicides can cause leukemia. Leukemia, also known as blood cancer, is a disease caused by certain problems in the body's hematopoietic system. In life, herbicides have been used as a kind of pesticides in life, and vegetables that have been used herbicides are brought to people's tables to bring herbicides into people's bodies.

According to some medical research reports, herbicides have become the main cause of childhood leukemia, and it can also be seen that the toxicity of herbicides is very harmful to children. It directly caused great harm to the human body's hematopoietic system.

Farmers use herbicides, if inappropriate, it may cause some damage to the lungs, and if you accidentally get it, it may burn.

There is nothing wrong with the period of respiratory contact, but it can cause bronchitis for a long time, which has an impact on the throat and respiratory tract.

The toxicity of herbicides is not great, so it is not harmful to the human body to a certain extent, because the medicinal properties of herbicides are mainly for herbaceous plants.

If a person accidentally gets into the mouth, it will be bad for the person's stomach and intestines, and it will cause vomiting or poisoning.

Herbicides contain many volatile harmful substances that farmers inhale when they use herbicides.

Precautionary measures. Proper selection and use of herbicides is key. Adjust the dosage and correctly grasp the use period.

Adjust the sprayer, spray evenly, and clean the sprayer thoroughly after spraying. After the application of long-term residual herbicides, the crop should be reasonably arranged. Rescue measures.

Herbicide pesticide damage should be treated differently, some pesticide damage does not affect the yield, and will disappear naturally with the growth of crops, for example, after the use of wild swallow wilt, wheat leaves turn yellow, and then the natural recovery; Some pesticide damage has caused a decline in output, and rescue measures should be taken in time.

Abnormal environmental conditions in production, such as freezing, high temperature, drought, hot air, etc., are similar to herbicide symptoms. The symptoms of leaf damage caused by top dressing are similar to those of contact herbicides. Nutrient deficiencies, pollution and over-fertilization, especially polluted deficiencies, sulphur dioxide, ozone, C12 and herbicides cause mesophyll greening.

Soil-borne diseases are similar to herbicide damage from some pre-emergence soil treatments. Deformed leaves caused by viral diseases and pathogenic bacterial infections are similar to leaf deformities caused by phenoxycarboxylic acids and soil treatment amides and carbamate sulfide herbicides. After the occurrence of drug damage, it should be observed from multiple angles and angles to avoid misdiagnosis.

The problem with herbicide sprayers that are not cleaned and cause pesticide damage is that herbicide drift is very common for non-target crops. 24-D butyl ester is the most widely used weeding variety in wheat field, because of its strong volatility, large drift and strong residue, it is easy to drift and harm nearby sensitive crops such as cotton, beans, vegetables and fruit trees when controlling weeds in wheat field. If the sprayer is not cleaned thoroughly, herbicide damage can also occur when other insecticides are loaded to control the above-mentioned crop pests and diseases.

Some herbicides have no effect on crops, while residual herbicides tend to harm crops. For example, the use of simazine in corn fields is more effective in weed control, if the seeds emerge slowly, the root tip sprout sheath and other parts will turn brown or rot when planting rapeseed in the next crop, which will have a great impact on the yield. Wheat grass spraying is non-pesticide harmful, and young roots will be hypertrophied and rotten after planting summer peanut stubble, and gradually die after yellowing, and the yield will be seriously reduced.

Field irrigation water should be drained immediately, flushed with new water several times, and neutralizing acidic herbicides such as lime should be applied. There is also a mechanical water spray irrigation that can be used to reduce the poison sticking to the leaves.

Crops should be watered so that the herbicide can be diluted, so that the damage to the crops will be less.

Crop damage caused by herbicides should be discontinued, as stopping the use of herbicides can prevent further damage.

Weeds are the enemy of crop growth, not only do they compete with crops for nutrients, but they also prevent crops from normal photosynthesis, causing crops to grow poorly and even wither and die. How can we get rid of weeds that affect the growth of crops? This is not as easy as getting rid of weeds in pots, and chemical herbicides can be a great help when manual work can be a great help when it takes time and effort to remove weeds from large fields of crops.

The effect of herbicides is to inhibit plant growth in the plant body, so that the plant is poisoned and killed. As a plant itself, it has a certain resistance to the drug, which can make the agent decompose in the plant and become ineffective. Different plants have different resistances, and the same agent may be quickly broken down in one plant and become ineffective, but not in another.

For example, in corn fields, spray a herbicide called "simazine", which kills weeds without damaging the corn at all. The reason is that when the seeds of weeds germinate, the roots absorb the liquid medicine and transport the liquid medicine to the leaves, which can inhibit the photosynthesis of the leaves of the weeds, so that they cannot produce nutrients, and the weeds will slowly die. The roots of corn will also contact and absorb the medicinal solution, but corn can decompose cimazine and make it a non-toxic substance, which does not affect the photosynthesis of corn and does not cause harm to corn.

Therefore, the use of herbicides to remove weeds is to achieve the purpose of weeding according to the difference between crops and weeds in contact with and absorption of herbicides, as well as the different transportation and decomposition of herbicides in crops and weeds. For different crops and weeds, there are different herbicides, and if you choose poorly, not only can you not get rid of weeds, but will damage the crops.

1. Morphological and structural discrimination.

Although weeds and crops are higher plants, they are different in form and structure, such as common weeds have broad-leaved, sharp-leaved and sedges, and crops also have sharp-leaved broad-leaved branches, for example, wheat belongs to sharp-leaved leaves, sowing Artemisia, pigs, mother-in-law, etc. belong to broad-leaved grasses, at this time choose to play broad-leaved herbicides (such as benzsulfuron, dimethyltetrachloride, chlorofluoropyroxyacetic acid, etc.), these agents only have an effect on broad-leaved weeds, and wheat belongs to sharp-leaved leaves (specific molecular structure, This article does not go into detail, it involves too many technical terms, and it is not easy to understand), so the weeds are killed, and the crops grow normally.

2. The principle of position difference.

The principle of the difference is mainly in the closed herbicide, or a small example to illustrate, in the case of corn, many friends will play the closed herbicide in time after the corn is sown, when the liquid is played, it will form a layer of film on the soil, under normal circumstances, weeds come out earlier than corn, at this time the weeds will absorb the liquid of the closed herbicide, resulting in death, and the corn is late, it will sprout and grow normally under the protection of the soil cover, which is the principle of the difference in the position.

3. Safety agent.

Now many crop post-emergence herbicides, are added with safety agents (wheat, corn, peanuts, etc.), such as the removal of wheat and wheat methyldisulfuron, when purchasing, there will be a bottle of adjuvant, the adjuvant is generally a safety agent, in such as corn herbicide, nicosulfuron, mesotrione, atrazine + adjuvant, this adjuvant is actually a safety agent, the role of the safety agent is to protect crops from being harmed by herbicides, and these safety agents do not work for weeds (the specific principle is also more complicated, Later, there is time, the little helper can tell you about the safety agent, welcome to pay attention), the end result is the death of weeds, and the normal growth of crops.

Just because herbicides will only work on plants other than crops.

I think the growth cycle of grass and crops is different, so there will be instructions on the herbicide and when it is suitable to be used.
