What are the matters to be paid attention to in the scientific and reasonable application of pesticides?

1. Pesticides can pollute the environment before using pesticides, so before using pesticides, you should first consider using physical control methods, such as manual weeding or setting traps for pests. Read weed and pest control tips to help solve some common problems.

Before buying pesticides, you need to read the label instructions and safety tips carefully, including the scope of application of the pesticide, the site where the pesticide is applicable, and check the packaging for damage or leakage. Buy only the amount of pesticide you need, and if you buy too much, the storage and disposal of the pesticide will also be a problem afterwards.

Second, the first point when using pesticides is to carefully read all label instructions and warning information, as well as countermeasures to deal with dangerous conditions. People and pets should leave the area while the pesticide is in effect, especially children, pregnant women and the elderly. Only after the pesticide has completely dried should other people and animals be allowed to come into contact with the pesticide-treated area.

Use pesticides only for the purposes stated on the label. For example, do not use pesticides indoors for outdoor use, and do not mix different pesticides together unless the label says that you can do so.

When preparing and using pesticides, do not drink, eat or smoke to avoid pesticides entering your mouth, so you should not rub your eyes or touch your mouth.

3. Rinse gloves and other protective equipment after using pesticides, and then wash your hands and face with soap after taking them off, as well as other parts of your body that may have been in contact with pesticides. Wash clothing worn for the use of pesticides thoroughly, and be sure to separate it from regular laundry.

Do not reuse empty pesticide containers and do not put pesticides in beverage bottles, as children or others may ingest them. There are also pesticides that come in powder form and look like milk powder on the surface. Therefore, when storing pesticides, they should not only be placed in a dry, cool and ventilated place, but also in a place out of reach of children and pets, and it is best to lock them.

Please follow the instructions on the product label to dispose of pesticides safely, do not pour them directly into the drain and do not burn them. Or you can ask others if they want to use this pesticide and give them the rest of the pesticide.

Choose the right pesticide for spraying, we must pay attention to the concentration, pay attention to the proportion of pesticides, these are very critical, we must choose good quality pesticides, spraying pesticides need to pay attention to the weather, pay attention to humidity.

To choose the right concentration, it is best to be guided by a professional, do not abuse pesticides, do not spray pesticides at will, and wear protective clothing to avoid poisoning.

Avoid using it in a dry environment under strong light, use it strictly according to the instructions, do not increase the concentration and dosage at will, and do not use it in rainy days.

1. Strictly read the instructions of pesticides, check the precautions, and follow the precautions. 2. Use pesticides in a qualified manner, and do not use prohibited pesticides. 3. Highly toxic and highly toxic pesticides cannot be used to spray vegetables and fruits.

First of all, it is necessary to choose the right concentration, we must pay attention to the appropriate amount, and then according to different crops, we must choose more cost-effective pesticides, and then we must choose the right varieties according to different conditions, such as rodenticides or insecticides, and then we can also choose herbicides.

How to use pesticides rationally? What should I pay attention to?

Pesticides are all too familiar to farmers, as they are often used in farming. So how to use pesticides rationally? What should I pay attention to?

The first point is to choose the right dosage form. Choose the appropriate dosage form according to different types of pest control and use methods. To control borers and underground pests, as well as to control perennial weeds, choose slow-release, long-lasting and intrinsically attractive pesticide pests.

Different dosage forms of pesticides have different physicochemical properties. Some are sustained-release but have a long effect, some are fast but have a short period of effect, some have a large particle size, and some have a small particle size.

The second point is to choose the appropriate way to use it. Fumigation and fumigation can be used to prevent and control crop pests and diseases growing in closed environments such as greenhouses, and the use period is generally determined according to the development period of pests such as diseases, insects and weeds, crop growth progress and pesticide varieties. There are many ways to use pesticides to prevent underground pests or pests that harm the base of crops on the ground.

Any kind of pesticide must be used in accordance with the recommended dosage of the pesticide label, and should not be increased or decreased at will.

The third point is to grasp the dosage and spraying quality. Arbitrarily increasing the dose is easy to cause drug damage, resulting in excessive pesticide residues in agricultural products. Attention should also be paid to the quality of the spraying, which must be evenly sprayed to achieve the control effect.

Try to avoid the sensitive period of natural enemies to pesticides, that is, you can not use it early or late, and you can not miss the favorable period for the prevention and control of diseases, insects and weeds. If this panicle bush is used early in the disease, the drug is used. Must be used in accordance with the recommended dosage on the pesticide label.

Fourth, pay attention to drug rotation to delay the development of drug resistance. Long-term continuous use of a single pesticide variety can easily make pests and weeds resistant to drugs. The rotation of pesticide varieties with different mechanisms of action is an effective method to delay pest resistance and ensure the control effect.

Strict spacing rules are observed. The pesticide interval is the number of days from a single application to the harvest of the hosiery. In order to ensure that the residues of agricultural products do not exceed the standard, agricultural products cannot be harvested during this period.

How to use pesticides rationally? What should I be aware of?

Pesticide crops play a beneficial role. So how should pesticides be used rationally?

First, do not increase or decrease the amount of pesticides at will. Pay attention to the order of drug dispensing when mixing drugs. These medicines need to be diluted with water.

Strictly follow the dosage specified in the instructions or the dosage recommended by agricultural technicians. Too little medication has no effect. Too much of the drug can cause drug damage, increase pesticide residues in agricultural products, and thus increase the cost of use.

Attention should be paid to the mixing of pesticides. Regardless of the mixture, it should be configured and used immediately.

Second, it is not allowed to arbitrarily increase the concentration of pesticides or mix multiple pesticides at one time. The concentration of a certain insecticide used to control a certain pest is the result of field trials. Generally, when farmers prepare potions, they often increase the concentration at will and reduce the water multiple, so that the concentration of spraying potions is too high, resulting in poisoning of crops during the safe harvest period.

Farmers often increase the concentration of organophosphorus pesticides to cause poisoning accidents. and should not be stored for more than 3 hours.

Third, inorganic pesticides are soluble in the environment and generally have low toxicity to the human body. Pay attention to the weather. Spraying pesticides in the field in foggy, windy and rainy days will cause a large loss of pesticides. It can be used to produce pollution-free food, green food and organic food; Inorganic pesticides include inorganic pesticides, inorganic fungicides, and inorganic herbicides, such as stone-sulfur mixtures, sulfur powder, Bordeaux liquid, etc.

Inorganic pesticides generally have small molecular weight and poor stability. Most pesticides should not be mixed with other pesticides.

Fourthly, this medicine is secondary and appropriate. A single spray generally does not control pests and diseases, especially pests and diseases. Due to the germination of bacteria is very inconsistent.

The laying and hatching of pests are relatively concentrated and can be eliminated by spraying once or twice. When mixing pesticides, be careful not to alter the appearance. If there are bubbles, heat, etc., stop stirring.

The mixture does not cause chemical effects, which may reduce the effect of pesticides or produce unknown drug harm.

It is necessary to understand the order in which pesticides are used, dilute pesticides with water, and pay attention to the regulations for the use of pesticides. Pay attention to the concentration of pesticides, but also pay attention to the dose, pay attention to the way of spraying pesticides, but also pay attention to the effect of pesticides, the dose of pesticides should not be too large.

We know that pesticides are indispensable drugs for farmers to plant, while using pesticides, we must pay attention to improving the safety awareness and environmental awareness of technicians and farmers, it is very important to use pesticides under the premise of safety, which can reduce the harm caused by chemical substances and better ensure the health of people's lives, so what problems should we pay attention to when using pesticides, first of all, do not use pesticides excessively, We can measure the effectiveness of using pesticides according to the degree of harm caused by pests in the field to crops, and excessive use of pesticides to avoid crop death. Secondly, to ensure the quality of pesticides, there is also a shelf life for pesticides, do not use expired pesticides because they can save money, so as not to lead to poor effects and losses for farmers. Finally, pay attention to the safety of medication, in the process of using drugs, do not spray casually because pesticides are not harmful to the human body, which is not right, and must be reasonable and safe to use.

First, do not overuse pesticides, excessive use is only harmful and not beneficial, we know that different pesticides on crops to prevent germs are different, and the drug needs to add a small amount of water in use, dilution treatment can be sprayed, to ensure the practicability of the drug.

Second, to ensure the quality of pesticides, pesticide quality is the key to our use of pesticides, if once the quality of pesticides can not be guaranteed, then the use of crops will have a negative impact on our crops, resulting in crops can not achieve high yields, must be sprayed in accordance with the instructions for use, do not increase the amount of drugs casually, scientific use can achieve the effect of use.

Third, to improve the safety of drugs, except for herbicides that are highly effective drugs, the rest of the effects are good, so we must not be disturbed by other crops when using such drugs, and the personnel who use drugs must wear drug protective clothing to ensure that our personnel are injured.

It is necessary to pay attention to the method of using pesticides, the number of times pesticides are used, the methods of using pesticides, the frequency of use, and the preservation methods of pesticides.

It is necessary to grasp the concentration of pesticides, pay attention to the composition of pesticides, pay attention to the time of spraying, and also pay attention to the location of spraying, and do not spray in a large area.

At present, there is a phenomenon of abuse and abuse of chemical pesticides, especially the phenomenon of blindly increasing the amount of pesticides.

The rational use of chemical pesticides should first be clear about the classification of pesticides, the hazards of pesticides, and the first aid measures after pesticide poisoning. 1. The classification of pesticides is divided into organophosphorus, organochlorine, and pyrethroid according to their chemical structure. Second, the harm of pesticides, one is the harm to the environment, but the harm to the human body.

There are three ways for pesticides to enter the human body, one is accidental exposure to a large number of people; The second is long-term exposure to a certain amount of pesticides, such as workers in pesticide factories, surrounding residents and farmers who use pesticides. At present, chemical pesticides are a means to quickly and effectively control agricultural pests and diseases, but if they are not used properly, they will not only fail to achieve the desired control effect, but also bring many bad consequences. So what should we pay attention to when using pesticides rationally?

1. According to the control object and the occurrence characteristics, select the most effective pests and pesticides in the application period, each pest and disease has the most sensitive period to the pesticide in the occurrence stage, and the use of drugs in this period not only has a good control effect, but also uses less dosage to reduce pesticide pollution.

2. The dosage of pesticides should be accurate, and it is not allowed to increase and reduce the dosage of pesticides at will, and the recommended dosage of pesticides is determined by the efficacy test. Reducing the dosage will reduce the effectiveness of the prevention and control.

3. Choose reasonable pesticide application equipment and application methods.

4. Scientific mixing and alternate use of pesticides Pesticide mixing and mixing is not a simple mixing of any two or more pesticides, and it must be mixed according to its physical and chemical characteristics, action characteristics, and prevention and control purposes, so as to achieve the effect of expanding the control spectrum, increasing efficiency, slowing down drug resistance, and saving labor.

It is best to use airplanes to spray quickly in a short period of time to maximize the effectiveness of pesticides and reduce harm to humans and the environment.

It is important to pay attention to the ratio of pesticides to water, and at the same time, the pesticide mouth should be lowered, because this will not cause serious effects on others, and it can also avoid the problem of small amounts.

It is necessary to pay attention not to let pesticides contact their own **, and then do a good job of protection when using them, and mix them according to the proportion, so that they can better use pesticides.

First of all, we should pay attention to the dosage of pesticides, we must strictly follow the standards to produce, and we should also pay attention to the safety of pesticides, which is very critical.
