What are the symptoms of herbicide poisoning? What is the method of herbicide poisoning?

Nausea, vomiting, unconscious, convulsions, high fever, these are typical symptoms of poisoning. The method of rescue is to induce vomiting at the first time, and then inject blood to cleanse the stomach.

The main manifestations are headache, nausea, weakness, dizziness, chest tightness; The best way is to send them to the hospital quickly for gastric lavage, and if the case is mild, drink more water to speed up the metabolism of the agent.

Nausea and vomiting, chest tightness, headache, weakness, and difficulty breathing; Be sure to go to the hospital in time to get emetics and gastric lavage to clean**.

The symptoms of poisoning are similar in all ways.

1) Gastrointestinal reactions include nausea, vomiting, abdominal pain, diarrhea and even blood in the stool, and after a few days, there may be toxic manifestations such as liver enlargement, ** and yellow eyes.

2) Respiratory symptoms are the most prominent, manifested by cough, phlegm and shortness of breath, and bruised lips. Death from acute respiratory distress syndrome (ARDS) is common within 1 to 3 days after large amounts of paraquat are taken orally. In some patients, even after resuscitation, pulmonary fibrosis continues to develop, often on days 5 to 9, peaking in 2 to 3 weeks, and eventually to death due to progressive inability to breathe.

Diquat poisoning generally does not cause pulmonary fibrosis.

Herbicides should be carefully selected for early culture. The use of metsulfuron-methyl and chlorsulfuron-methyl is not allowed in wheat fields. When using benzylsulfuron-methyl herbicide, the time and dose of dosage should be strictly controlled.

In cross-shaped fields, herbicides with high efficiency and low toxicity should be used, and the maximum residue level should be as low as possible and no herbicides should be used for the next maize. Double-check the product used and the dosage.

Double-check the name, content, culture, controls, sensitive culture, and so on before use. According to the types of weeds in the field, select herbicide varieties that are safe for corn, carefully read the herbicide instructions, master the use technology, do not increase the dosage or expand the scope at will, strictly prohibit the use, and prepare chemicals for comprehensive control of diseases, insects and weeds without fully understanding the performance of each pesticide. All types of herbicides must not be mixed with pesticides or fungicides.

In order to repair and adjust the nozzle, it is better to choose a fan-shaped nozzle instead of a conical nozzle for manual nozzles. Before the operation, adjust the agronomic technical standard state, the herbicide should not swing left and right, such as the selection of 2,4-dibutyl ester and nicosulfuron, should be carried out at the level of 2 3-corn leaves. Too early or too late can easily damage the medicine.

The spraying time is usually 8 hours, after 17 p.m. The wind speed is less than 4 m s and the humidity is more than 65%. If the temperature is higher than 27 "8451", spraying should be stopped after sowing weeds When using contact herbs, a protective coating should be applied to the nozzle and done under wind or light breeze to prevent the corn plants from spraying and damaging the corn.

Choose the right time to spray. It should not be used in maize just emerging, maize growing areas, and sandy soils to avoid drug damage. Chemical weeds in corn fields should choose herbicides with a wide spectrum of weeds and moderate duration, which will not affect the subsequent crops, mainly based on the pre-planting of the soil, supplemented by the post-treatment of seeds and leaves, and it is best to use it before sowing, after rain or after application with a rainfall of 15 20mm, if the appropriate soil treatment time is missed, herbicides should be purchased in time for stem and leaf treatment, the application amount and concentration should be strictly controlled, the dose of each liquid container should be carefully calculated before surgery, and the dose should be accurately measured.

The dosage of most herbicides increases with the content of organic soil and clay particles. The dosage should be determined according to the soil texture and organic matter content. The amount of water per mu should not be less than 30 liters, otherwise it will be applied unevenly for the first time.

Note that high concentrations of pesticides can easily lead to drug damage.

Dilute the concentration of herbicide as much as possible, use it in the place where it should be used, avoid rain and hot weather, stay away from small streams and rivers, understand its medicinal properties, and put it out of the reach of children.

We must pay attention to the selection of the right herbicide, and pay attention to the concentration of the herbicide, pay attention to the number of herbicide spraying, we must pay attention to the growth of the plant, and spray it in accordance with the scientific method.

Herbicides have not been used in our country for a long time. In my impression, it was only in the eighties of the last century that it began to be popularized and used. Herbicides are divided into two categories: biocidal herbicides and selective herbicides.

Due to the ignorance or carelessness of the herbicide habits in the application of farmers, some herbicide pesticide damage occurred in the actual application, resulting in damage to crops and even death.

So, how do you prevent herbicides from causing pesticide damage to crops?

First of all, the soil structure is damaged, and herbicides with high residues in the water soil are not used. For example: herbicidal king, chlorsulfuron, amibesulfuron, mesulfuron-methyl and other ......These herbicides have been (or are progressively) banned.

They remain in the soil for a long time (some years, even more than ten years), and after a few years, they are ...... to crops such as watermelon and sugar beetThe cultivation of pesticides is harmful. If farmers have used a large number of the above pesticides before, it is recommended to plant gramineous crops instead of single-season dicot cash crops. In order to avoid drug damage and unnecessary economic losses.

Secondly, do not use herbicides indiscriminately. In view of the characteristics of selective herbicides, it is important not to confuse the selected objects in use. If the herbicide is used incorrectly, it will be harmful to the pesticide at least and the harvest will be wiped out at worst.

Therefore, the herbicides purchased should be classified and marked prominently, and carefully checked and checked before use.

Third, do not abuse herbicides. In the use of selective herbicides, the drug should be used according to the requirements of the instructions: it should not be used before the safe period of crop growth that is required to be reached, nor should the dose be increased arbitrarily in order to kill the herbs quickly.

These are prone to pesticide damage and delay the growth and development of crops. The application of some compound biocidal herbicides is also prone to pesticide damage if used improperly. (For details, you can refer to the "How Many Days Can You Grow Crops After Using Methyl Glyphosate").

Fourth, develop good medication habits. Before each use of herbicide, the spraying equipment should be cleaned and sprayed with water; After applying the drug, wash it again with water and test spray. In order to avoid the residue of herbicide to cause pesticide damage to crops.

When using herbicides, try to choose sunny and windless weather. When spraying herbicides, use herbicide protective cover to avoid herbicide drift and other crops from causing pesticide damage.

Introduction: When planting crops, it is necessary to spray some pigs at the ripening stage, so that it can be a good protection against some diseases. The concentration itself can also make its nutrients meet the conditions for growth, because if there are weeds around, then it will absorb the nutrients with him, which can cause important malnutrition.

Herbicides like those herbicides can be used to get rid of weeds through some effective drugs, but with the variety of herbicides it is different for the type of crop and the growth period of the crop. However, the key symptoms of common insecticides can also be understood by consulting the relevant people. By reading the relevant information, I hope to help you solve the problem.

Growth regulators like growth regulators are mainly common herbicides, which can play a good role in regulating night flowers at noon. For example, the phenomenon of those behind the leaves or the intensity will lead to the dwarf of the plant, and in severe cases, it will be heard for a long time, and the key symptoms at this time are long-lasting, which can have a great impact on the last growth period. Therefore, it is necessary to spray growth regulators in time, which can effectively restore crops to normal in the later stage.

Amide herbicidesAmide herbicides are the main representatives of those growth regulators, and it can be understood that the typical key of herbicides such as alachlor and metolachlor is that the seedlings are short or deformed. Crops like those leaves are affected by tight curls of the heart leaves, and they cannot be normal, so at this time it is necessary to spray drugs in time.

The main symptom of herbicides such as dinitroaniline herbicides is that the root growth of crops is inhibited, and it is shorter, but the roots are very thick. For example, the root tip will become thicker, and the root or hypocotyl will appear large. In severe cases, it can lead to those crops not being able to emerge, and at this time, it is necessary to spray herbicides in time.

White spots appear on the leaves, and the veins are sometimes red or purple, and sometimes the tips of the leaves turn green and white, sometimes yellowish or pale green. Sometimes the color changes from yellow to orange and spreads upwards through the veins.

Known symptoms include yellowing of old leaves, death at the end of the growing point, sometimes redness, sometimes purple, and white spots on the oats, and atrophy of the petioles, curling down and purple at the edges of the leaves, etc.

It will lead to unclean weeds, and the plant will have an impact, which will lead to problems with plant growth, resulting in uneven growth of plants, which will seriously affect the growth of plants and affect the yield of plants.

Commonly used herbicides have symptoms, the first kind of aryloxyphenocypropionic acid: commonly used pesticides are Wenzhide, Hecaoke, Gaicaoneng, Weiba, Huma, etc. The main symptoms are plant deformity, yellowish-brown growing spots, and purple or yellow heart leaves.

The second diphenyl ether: commonly used pesticides are glucosin ether, weed incineration, tiger and so on. The symptoms are brown necrotic spots on the leaves, and in severe cases, the leaves are deformed, scorched, and there are no new leaves, the third type.

Amides: Commonly used agents include Lasso, Doer, Dipan, Buchlor, etc. The symptoms are yellow when the leaves are mild, and the leaves are spotted, curled and wrinkled when they are severe, and finally die.

The fourth kind of carbamate: commonly used pesticides are herbicidal, herbicidal, oat, etc. The symptoms are curly leaves, many tillers, thick stem bases and new roots, and short plants.

What are the symptoms of herbicides? White spots will appear on the leaves, and the tops of the cotyledons and true leaves will turn white. It comes into contact with herbicides such as alaclo (fast harvesting) or photosynthesis.

The top of the leaf turns green, turning white, sometimes yellow or light green, and spreading down through the edge of the leaf. They are triazine herbicides that enter plants through root absorption, such as atrazine, diuron, etc. Injuries caused by inhibitors such as atrazine.

Plant growth regulator EM spray.

When crops are damaged by hormonal herbicides such as 2,4-D butyl ester, 2-4-methylchloride, chlorpyrifos and chlorpromazine, or by the internal addition of conductive herbicides and herbicide residues from previous crops, seedlings mainly show yellow leaves and white burnt spots. Since dimetone is an inhalation-free contact herbicide, after minor damage to the drug, the crop may slowly grow new leaves in about a week and gradually return to growth, which affects the symptoms of herbicide insecticide damage: first, starting from the roots, there are few root systems, the roots become black and necrotic, starting from the leaves of the heart, the leaves and young leaves of the heart turn green, yellow, twist and die along the veins, and the leaves have brownish-yellow spots on the leaves.

Plants can be unusually overeaten or sprayed repeatedly to cause damage to the drug. The lower part of the leaf rots, and then the old leaves turn yellow. 2.

It is a grass herbicide (e.g., Natchijing, Gram Grass, Silversand, Cover Grass may have short buds, stunted growth, and dark green leaves. Drugs derived from cell growth inhibitors such as flularin, shitianbu, and rhubarb and other herbicides.

If the leaves and stems show symptoms of hormonal damage, the petioles are curled and the leaf margins are curved, and field management is strengthened to promote the early and rapid growth of seedlings. When the damage caused by exposure to herbicides is mild, it usually recovers on its own; It can enhance field management, tillage, soil release, fertilization and water, while spraying 1% 2% urea on the leaves. Slow growth.

Luminaries may recover within a week, and heavy luminaires will die. Atrazine poisoning symptoms III.

The best way to remove herbicides is as follows:

1. Choose the right herbicide next to the year: use it in strict accordance with the instructions, do not overspray and respray, leak spray, and prevent drifting with the wind and drifting with the water.

2. The pesticide damage caused by hormone herbicides, such as the pesticide caused by herbicides such as natiyun, can be alleviated by spraying gibberellin, Bihu, or sprinkling grass ash and activated carbon.

3. The herbicide damage of the contact type is only the aboveground part or local damage in the initial stage, and the growth can be restored by applying fast-acting fertilizers to supplement nutrients such as nitrogen fertilizers. Herbicides are mostly acidic, so they can also be reduced by sprinkling lime and plant ash.

4. For pesticide damage caused by soil treatment, the soil can be washed by soil plowing and watering to reduce the residue of herbicides in the soil.

5. For plots with light herbicide damage, wild birds can recover their growth through intensive cultivation.

What are the specific drugs for removing herbicide damage?

1. Herbicides will inhibit the growth of crops and lead to nutrient loss. To remove herbicide damage, you can apply fast-acting chemical fertilizers, top application of ammonium nitrate, ammonium sulfate, etc., and can also spray foliar fertilizer, with 1 urea or potassium dihydrogen sulfate solution, which can promote crop growth, improve pesticide resistance, and reduce pesticide loss.

2. There is no special drug to remove herbicides, which can alleviate the damage and increase nutrition.

3. Herbicide ash has been growing crops. Herbicides can also use fast-acting fertilizers, etc.

4. The main ways to remove herbicide damage are accelerated nitrogen fertilizer and foliar fertilizer spraying in a growth agent.
