What are the most common ways to use pesticides?

The most common and important method of application refers to the use of mechanical force of medical equipment to atomize the liquid medicine to form fine droplets and spray them on the target. Many pesticide formulations are sprayed with water. Before preparing the liquid, it is necessary to calculate the amount of pure pesticide used per unit area according to the content of the active ingredient in the pesticide preparation, so as to determine how much liquid medicine to take and how much water to mix.

There are no strict regulations on the amount of water used for routine spraying, and it is generally determined based on the growth of plants in the field. A variety of dilution sprays are commonly used in production, such as 50% iprodione wettable powder 800 times liquid to control asarum leaf blight. When diluting with the multiple method, it should be noted that when the dilution factor is less than 100 times, the amount of water added should be deducted from the dosage.

Powder spraying is a method of spraying pesticide powder out of the equipment with a manual or motorized powder sprayer and drifting to the target surface in a short distance. Powder spraying is easy to operate, does not use water, has high work efficiency, is safe for crops, does not increase environmental humidity, is suitable for use in environmentally closed protection areas, can save drugs and increase the amount of deposits; On the other hand, the likelihood of disease occurrence is reduced compared to spraying methods because no additional humidity is added to the environment. The disadvantage of powder is that the drift is strong, the adhesion is poor when used in the field, the wind and rain will make the powder particles fall off the target, and the conditions should be strictly controlled when used, so that more powder falls on the control object.

Seed dressing is done by mixing the seeds with the medicine so that the seeds are covered with a layer of powder, which kills the germs carried by the seeds or protects the seeds from pests and diseases in the soil. There are two kinds: dry and wet.

The dry method is a dry blend with the powder, the seeds and the measured drug are mixed in a container, so that the powder is evenly attached to the seeds, and the drug enters the soil with the seeds after sowing. The wet method is the spraying of chemical solutions made of emulsifiable concentrate, wettable powder, suspension agent, etc. Place on the seed pile and flip the seeds over when spraying so that the amount of seeds is evenly used.

After wet mixing, the seeds are usually packaged to kill pathogenic bacteria that invade the seed coat. After sowing is a sensitive period for seed germination, it is easy to produce pesticide damage, so it is necessary to use drugs with caution.

The poisonous bait method is to use wheat bran, soybean cake and grain seeds that pests like to eat as bait, add an appropriate amount of water, stir evenly, and then add pesticides with stomach toxicity. The poisonous bait is mainly used to control underground pests such as needleworm, grub, grub, ground tiger, etc., and good control effects can be achieved when applied properly. Bait can be buried in the soil with the seeds at the time of sowing, or it can be sprinkled around the base of the stem.

Covering with a small amount of soil can prolong the effect. In particular, after making poison bait, be sure to bury it in the soil when applying it to avoid harm to poultry and birds. The bait can also be chopped with fresh grass, wild vegetables, etc.

Trichlorfon and phosphine are the most commonly used agents to make poison bait.

Spraying, soaking, etc. There are many most common methods of pesticides, but the most used is direct spraying, and atomized pesticides cover a wider area and are more effective; There is also a method of soaking seeds is also very effective, before the seeds or seedlings are too heavy, soak them with just the right proportion of the liquid medicine, which can prevent the disease of seeds with bacteria.

Spraying can be carried out, and seed treatment can also be carried out, and fumigation can be done, these are relatively common practices, and they are all very good, and the yield will be very high.

In fact, it is to pour pesticides into the watering can, and then carry out a certain mechanism with the water, spray the watering can in the field, or directly sprinkle it on the roots of the plant, so that he can volatilize it himself.

There are a lot of them. When spraying pesticides, we can use professional machines to spray. It can also be sprayed manually, but it must be in moderation and not excessive. However, the most common methods of use of pesticides are spraying, irrigation, root application or sprinkling.

The most common methods of using pesticides are spraying, spraying, sprinkling, splashing, root irrigation, seed dressing and so on. Spraying pesticides is one of the most commonly used methods of application.

In general, there are 4 ways to use pesticides, namely spraying, scattering, root irrigation, and powder spraying, which are relatively common in daily life. It is also the most commonly used method in the process of spraying pesticides on crops. In the process of using these methods, the efficiency of use and the safety factor of use are relatively high, without too many technical requirements, even if they are not used often, as long as they are used several times, they will be proficient a lot.

Now let's talk about the specific steps of using these methods in detail, such as the first spray method. This method of use is to mix the pesticide with water in a specific proportion according to the instructions, put it in a sprayer, and then spray the crops. The second type is casting.

This method is very straightforward, which is to bury the pesticide directly in the soil, or sprinkle it in the paddy field where we need to use the pesticide. The third method is the root irrigation method, in fact, this method is similar to the first method, which needs to be mixed with water in the corresponding proportion, and then directly irrigated to the roots of crops. The last method is the powder spraying method, but in fact, this method is not very common, and it is not the most commonly used among the four methods, because this method uses air flow to spray the powder on the leaves of crops.

Now this season is also the period of high incidence of various diseases and pests and plant infectious diseases, so farmers who generally run crops in rural areas pay more attention to these problems, but we still have to pay attention to it in the process of use, so as not to get it to ourselves. <>

Although everyone may be aware of these problems, there are many such examples of accidents due to some pesticides every year. Therefore, we should be very careful in the process of use, do not take it lightly, especially if there are children or the elderly at home who are not familiar with these drugs, we should put these drugs in a place where they can't see or reach, and try to avoid direct contact with this drug, so as not to happen.

First of all, we should prescribe the right medicine, and at the same time, we should also choose some pesticides with better effects, with some bactericidal agents, and also need to choose some herbicides, or you can choose some mixed, we must pay attention to the problem of cost performance.

It should be diluted with water, and the correct time period should be chosen, and at the same time, it is necessary to pay attention to the hazards of pesticides, and also pay attention to the spraying skills of pesticides, to understand the medicinal properties of pesticides, and so on.

Choose a good spray head, and learn to irrigate the roots, but also pay attention to the way of pesticide spraying, but also pay attention to the efficacy, but also pay attention to dilution.

Conventional methods of use, including spray method, powder spraying method, seed dressing method, poison bait method, and seed soaking method, are all common pesticide use methods.

There are spraying method, watering method, powder spraying method, soaking method, poison bait method, fumigation method, these methods are conventional methods.

It is used to prevent pests and diseases, can be used to dress seeds, can reduce microorganisms in the soil, can be used to kill germs, and can be used to ** plant diseases.

First of all, we should choose the right pesticides, but also should pay attention to the proportion and dosage of pesticides, we must grasp the amount when using, and do not spray pesticides excessively, otherwise it will affect the growth and development of plants.

The correct way to use pesticides is to use pesticides in proportion, mix them with other chemical fertilizers, mix pesticides with water, use pesticides appropriately, and dilute pesticides.

Understand the instructions for the use of pesticides, pay attention to the role of pesticides, understand the characteristics of pesticides, pay attention to the classification of pesticides, pay attention to the rules of using pesticides, and pay attention to the scope of pesticide prevention and control.

The correct way to use pesticides is to take a certain amount of pesticides, add water to dissolve them, or dilute them, spray them on the roots of plants, and pay attention to wearing masks and gloves.

It is necessary to pay attention to the growth of plants, to choose targeted pesticides, not to abuse pesticides, to pay attention to the composition of pesticides, and to choose less toxic ones.

Choose the best application period, do a good job in the work of pests and diseases, grasp the occurrence law and characteristics of various pests and diseases, follow the policy of prevention first, comprehensive control, adhere to the principle of prevention and pest control, and grasp the key prevention and control period according to the investigation of on-site pest and disease hazards, so as to achieve early treatment and small treatment. Choose the best time to apply pesticides, cloudy or sunny, 9 to 10 a.m. after the dew is dry, 4 p.m. to 7 p.m. before and after sunset, spraying pesticides when pests are active, can improve the control effect.

Be aware of the weather changes and do not spray in case of high winds, rain, rain or dew. If it has just rained heavily after spraying pesticides, spray again after the sun shines. Spraying pesticides is prohibited during flowering and before harvest, and crops and fruit trees are vulnerable to damage when pesticides are applied during flowering.

If applied before harvesting, pesticides can create residues on crops that can cause food poisoning. Generally speaking, the residue period of high-efficiency and low-toxicity pesticides is about 60 days, and the residue period of high-efficiency and low-toxicity pesticides is about 15 days. Therefore, whether it is grain, vegetables or fruit trees, it is forbidden to use drugs before harvest to avoid food or food poisoning.

Many vegetable farmers are accustomed to spraying every three or four days, thinking that they can rest. In fact, this approach is very wrong. Not only does it increase costs, but it also leads to a rapid increase in pest resistance that becomes uncontrollable once it occurs.

The rational approach is to use drugs early in the occurrence of pests and use drugs that are highly effective, low toxicity, and have a long duration. For diseases, it is recommended to regularly spray protective fungicides, such as mancozeb, chlorothalonil, methyl tobuzin, etc. In the early stages of the disease, symptomatic fungicides are taken depending on the type of disease.

For example, for downy mildew and Phytophthora, enoylmorpholine and methamethaline are used, and some copper reagents are used for bacterial horn spots, etc.

Vegetable farmers often ask me if it is appropriate to pump a few buckets of water per mu when spraying. The most reasonable amount to spray is to spray the leaves wet without dripping. Scientific experiments have shown that if the leaves are sprayed with dripping water, the amount of liquid medicine left on the leaves is only about half of what is not drip when the liquid is not dripping, therefore, when spraying dripping water, it not only causes a lot of waste, but also greatly reduces the actual control effect.

Some vegetable farmers are accustomed to spraying a small amount of liquid, and the drug concentration is very high, which is also unscientific, because it is not only easy to cause drug damage, but also leaks seriously, fails to reach the target, and the control effect is not ideal.

When using agricultural drugs, we must make a reasonable dilution, and at the same time there must be a proportion of contrast, and we must shake evenly, so that it is better to use, but when spraying pesticides, we must pay attention to our own safety, and try to put the pesticide mouth a little lower when spraying pesticides.

You can use spraying, or watering, or root sprinkling, or powder spraying, and soaking method, these methods are very good for the use of pesticides.

The use of pesticides includes, using sprays, artificial methods, poisonous bait method, powder spraying method, poisonous soil method, and so on.

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.
