What do you know about the correct use of commonly used pesticides? The use of pesticides should not only be based on the types of crop diseases, insects, weeds, rodents and other pests, but also the correct use methods. It is required to accurately calculate the dosage of drugs, and strictly grasp the dosage of the dispensing concentration and timely application area.

Fumigation: Fumigation is a method of eliminating pests and diseases with fumigants or easily volatile gas fumigation, which is mostly used in closed environments such as warehouses and greenhouses, and some agents can also be used for household grain storage. It is characterized by the effective control of concentrated and hidden pests and pathogens.

Dusting: Dusting and dusting machinery to sprinkle powdered pesticides on crops or pests. Pesticides used for spraying are generally low-concentration powders or mixtures.

When there is no dusting instrument, it can also be sprinkled with soil methods. Dusting is the simplest application method, especially in arid areas and water-scarce mountainous areas, and is an effective means of controlling outbreak pests and diseases. However, the dosage is relatively large, the loss of the powder by wind and rain is relatively large, and the residual time is relatively short.

Poison bait: Mixed with stomach poison to make poison bait, which can be used to control underground pests and rodents. The bait can be rice, corn, wheat, wheat bran, rice bran, soybean meal, peanut cake, rapeseed cake, grass, etc.

The poison bait is generally mixed with the seeds, mixed evenly, or sprinkled directly in the sowing furrow before sowing.

Spraying and mist: spraying liquid drugs on crops and pests and pests with spraying equipment and pests on the leaves of the pesticide application method in a timely manner. The preparations for spraying include wettable powder, emulsifiable concentrate, aqueous agent, concentrated emulsion and emulsion.

The spray should be even, thoughtful, and appropriate (it is better to have the leaves fully moistened but not dripping). The finer the droplets, the smaller the spray volume. The advantage of spraying is that the amount of medicine consumed is small, the liquid medicine is easy to stick to crops and insects, and it has the ability to be easily blown away by the wind and resist rain.

Seed dressing, soaking and soaking seedlings: Mix the powder pesticide directly with the seeds in time, or spray the liquid medicine on the spread seeds, so that the seed surface is evenly covered with the drug and then stirred. After seed dressing, it is generally necessary to pile up for a certain period of time, so that the seeds can fully absorb the drug and play the role of the drug on the fumigation and poisoning of diseases and insects.

Choose the appropriate application method, pests have different lifestyles and activity parts, and different pesticide application methods should be adopted to achieve the purpose of preventing and controlling pests and protecting natural enemies.

When using pesticides, you must pay attention to the number of times, do not spray too much, and when using pesticides, you must pay attention to safety issues, do not bring unnecessary trouble to yourself, and you must pay attention to your words and deeds when using pesticides, do not hurt yourself, but I think the most important point is that you must wear the corresponding protective gear when using pesticides.

When using pesticides, we should use them in accordance with the instructions and the labels on the pesticide bottles, do not expand the dosage and spraying scope at will, wear rubber gloves and masks when spraying pesticides, use the spraying amount reasonably, and control the number of times to take medicine.

When using pesticides, pesticides and water should be mixed in a certain proportion. When in use, it must be used in a sunny place, never in a closed place, and after using pesticides, you must wash your hands frequently, and clean the exposed **.

I don't know much, but I know that the use of pesticides is mainly based on the season and temperature, and I should also choose some suitable methods for crops. It is necessary to adhere to the principle of reducing pollution and reducing the amount of pesticides used, so that pesticides can be used correctly.

In general, young larvae are less resistant to pesticides and become more resistant as they age. Therefore, when many farmers find pests and diseases, they start spraying too late, causing harm and making it difficult to exert the effect; In the process of spraying pesticides, it is not proportional and there is no special measuring tool, and when the concentration exceeds the regulations, it is not only easy to cause pesticide hazards, but also improve the resistance of pests and diseases. Some farmers even think that the higher the concentration of pesticides, the greater the control effect on pests and diseases, which is incorrect, but sufficient water consumption is very important.

Because bacteria and eggs are mostly concentrated on the back of the leaves, it is a mistake to simply increase the concentration of pesticides and ignore the amount of water used. When farmers choose pesticides, they often tend to choose pesticides with fast acting effects, and pursue timeliness too much, hoping that pests can be killed immediately after spraying. This thinking often leads to their crops with pesticide residues that are too high to meet standards; Therefore, farmers should pay attention to the slow efficacy of pesticides, which can only really play their role in the later stage of pesticides; Pesticides are commonly used in spraying, root irrigation, sprinkling, seed dressing and other methods.

Taking the spraying method as an example, the water is mixed into the liquid medicine according to the requirements of the instructions, and the pesticide is diluted and sprayed with a sprayer.

It should be noted that the dosage should be controlled, not too high or too low, protective measures should be taken, and the application time should be determined according to the type of agent. For example, some pesticides should be used at higher temperatures, while others should not be used at high temperatures. The mixed use of pesticides does not affect the stability of the active ingredient.

It can be mixed with chemical pesticides when controlling pests, but not with chemical fungicides, otherwise it will kill effective fungi; When mixed with alkaline pesticides, organophosphates and pyrethroids and dithiocarbamate fungicides produce complex chemical changes that destroy their active ingredients.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

According to the situation of crops, diseases, insects and weeds to grasp the dosage and concentration and applicable area, to use correctly, you can spray some pesticides on crops, so that you can eliminate the virus more balanced, and dilute it completely when using pesticides, so that the pesticide can better melt and the concentration is balanced.

Mix the pesticide with water according to the instructions for use, and then put it in an appropriate container and spray it, be sure to pay attention to safety during the spraying process, wear a mask and gloves, and do not spray it on your body.

First of all, we must prescribe the right medicine and find the right pesticide. And to learn new techniques. Be sure to go to a regular place to buy a regular pesticide. Pay attention to safe medication and do not allow yourself to come into contact with pesticides.

Dusting: Dusting and dusting machinery and equipment are used to sprinkle powdered fertilizers on crops or harmful organisms. Fertilizers used for spraying are generally powders or blends at lower concentrations.

When there is no powder spraying equipment, you can also use home remedies to apply. Dusting is the simplest way to use, especially in mountainous areas where arid climates work with little water, and is a reasonable way to prevent outbreak pests. However, the dosage is relatively large, and the powder is more damaged by sun and rain, and the residual time is relatively short.

Powder spraying and dusting must be evenly proportioned and thorough, so that the surface layer of crop pests is covered with a very thin layer of powder, and it is not necessary to spray to the level of whitening crop leaves. If the leaves are white, it will not only consume the drug, but also cause fertilizer damage. When spraying drugs, try to spray the best effect of mechanical equipment in the morning when there are dewdrops and no wind, and spray powder around strong winds and headwinds.

Spraying and mist: Spraying liquid drugs on crops, pests and diseased leaves with a spraying machine spraying method for immediate spraying. The traditional Chinese medicine preparations used for spraying include wettable powder, acetamiprid, liquid, concentrated solvent and emulsion.

The spray should be even, thorough, and appropriate (it is better to have enough moisture on the leaves but not to drip). When spraying, the finer the particles, the lower the spray volume. The advantage of spraying is that the amount of medicine consumed is reduced, and the potion is very easy to stick to crops and tapeworm eggs, which is <>

It has the ability to not be easily blown by the wind and resist rain. Therefore, the effect is long-lasting and the effect is very good. It should be noted that the spray amount must be matched with the spray machine, the spray requirement is that the smaller the fine particles, the smaller the spray amount, and the pesticide dosage form for ultra-low capacity is a special type of degreasing agent, which can be applied immediately without releasing water.

Compared with the basic spray, it has many characteristics, such as good immediate medicinal power, long residual period, and high efficacy. However, there are also shortcomings, it suffers from wind speed, wind frequency and air hazards, and highly toxic pesticides are not suitable for application. Poor coverage behind crop leaves.

The actual effect of sterilization is poor.

The most common methods of pesticide use are spraying, powder spraying, seed treatment, soil disinfection, injections, for garden trees, fumigation; When using pesticides, we must use them in accordance with the pesticide safety rules, put an end to all prohibited pesticides, and use pesticides to be safely isolated and do a good job of safety protection measures to protect the safety of people and organisms, and we must properly dispose of the remaining pesticides.

If you need to spray, you can use a watering can to solve the problem, which is more uniform and safer, and the ratio is proportioned according to the fixed concentration.

You can choose the method of spraying, or you can choose watering, you can choose direct spraying, or you can choose injection. Generally speaking, pesticides should be used in small quantities and many times, and high concentrations of pesticides should not be selected each time.

The more common ones are actually three divisions, the first is spray, the spray is actually put in the kettle and sprayed out by pressing air. The second is actually dusting, and the third is actually the way of irrigating the roots. The use of pesticides can be selected according to different plant diseases.

I don't know, although I often use pesticides, but I don't have a detailed understanding of the conventional use methods, I just protect myself when I use pesticides, and then I will choose a suitable temperature weather to use before using pesticides, but I haven't learned so many pesticide methods.

Spray method, poison bait method, powder spraying method, seed dressing method, sprinkling method, seedling impregnation method, pouring method, root irrigation method, smearing method, fumigation method.

I know that these methods are, spraying, dusting, sprinkling, root irrigation, seed dressing, etc., and these methods are very useful.

They are fumigation method, wiping method, root irrigation method, pouring method, topdressing method, powder spraying method, sprayer method, poison bait method, seedling impregnation method, and seed dressing method.

These methods of use are spraying, spraying, sprinkling, splashing, root irrigation, seed dressing, seedling impregnation, poison bait, smearing, and fumigation.

I know two or three of them, you can spray pesticides on the foliage, you can spray pesticides directly with watering, or you can spray pesticides directly on the stems of plants and the roots of plants.

In the field of agricultural production, pesticides play an increasingly important role in the prevention and control of pests and diseases and the improvement of crop yields. However, due to the differences in pesticides, physical properties, etc., there are various differences in the configuration and use of pesticides. There are ten common ways to use pesticides, and we will explain the following.

First, pesticides can be applied directly to crop shoots or pests. Common application methods mainly include: spraying, powder spraying, fumigation, etc.

The spray method mainly refers to diluting the pesticide water to a certain extent, and spraying it with a spraying device. At present, the use of low-volume spray is promoted, with droplets of about 100 microns; The mist machine spray is an ultra-low volume spray, with droplets in 5 75 microns, and the number of droplets is 15 times that of ordinary spray. The spray method is suitable for wettable powders, water agents, emulsions and other pesticides.

Powder spraying method is the use of powder pesticides, suitable for places where there is a lack of water sources, and is generally sprayed with a duster. The advantage is that it has high efficacy and does not require water.

Fumigation is a method used to volatilize pesticides and control pests and diseases. It has the advantages of high efficacy, fast action and no need for water.

Secondly, the pesticides used in fruits, seeds, seedlings and other propagation materials are treated with spray fumigation and dressing and brushing. It is necessary to use the appropriate treatment concentration, time and method according to the object of control.

Finally, for the application of pesticides to the soil or root areas under the crop, as long as there is spraying, watering, burrowing and injection, etc. In short, the common use of pesticides needs to be determined according to the part of the pesticide action.

The above is the common use of pesticides introduced by me according to the classification of pesticide application parts, which we can use in future agricultural production.

First of all, it is necessary to use it in rotation with other pesticides, and then you should also pay attention to the composition of pesticides, the concentration of pesticides, the combination of water and water, and the time of use, and you should also avoid high temperatures when using.

It can be sprayed directly on crops, or directly dusted, or directly flushed in water, or smoked, or directly watered, or injected, etc., these methods are more effective.
