What are the specific knowledge of pesticide application methods?

There are many ways to use pesticides, according to their different uses, as well as different growth stages of crops, different pests and diseases, or in different environments, the corresponding pesticide use methods are used to achieve better pesticide control effects, save pesticide inputs, and reduce environmental pollution.

1. Spray method: In agricultural production, our most common application method is spray method, which is to mix and dilute pesticides with water, and then spray pesticide solutions on crops through sprayers and other instruments, so that pesticides can be attached to the straw or leaf surface of crops to prevent and control pests and diseases.

2. Soaking method: This method is mostly used for the practice of seeds before planting, after dissolving the liquid medicine with water, soaking the seeds in the solution, or watering the liquid medicine on the seeds, playing a method of preventing and controlling underground pests.

3. Smearing method: This method is to apply pesticides to local places such as plant stems, so as to achieve targeted medication, prevent and control pests and diseases, or regulate plant growth.

4. Spraying method: spraying method is mostly a method of implementing powder pesticides, the powder pesticides are sprinkled on crops through the sprayer, or manual sprinkling, and the powder is sprinkled on crops.

5. Fumigation method and smoke method: these two methods are a measure to control plant diseases and insect pests by using the smoke or odor emitted by pesticides. These two methods are commonly used in greenhouses, or in small environments such as orchards.

6. Root irrigation method: This method is to directly inject pesticides into the soil of plant roots to prevent and control plant root diseases and pests, and this method is mostly used for some trees.

In addition to the above 6 kinds of pesticide application methods, there are soil treatment methods, poison bait methods, injection methods, etc., in the agricultural pest control, according to different needs, take corresponding methods.

Pesticides play a very significant role in the prevention and control of pests, diseases, weeds, rats and other pests in pesticide production, but if they are not used properly, they will have an adverse impact on pesticide production. Long-term single use of a certain or a certain type of pesticide will produce resistance to some pests, in order to prevent and control these resistant pests, arbitrarily increase the concentration and dosage, will further accelerate the formation and development of resistance.

Improper selection or use of pesticides will kill the natural enemies of pests, make pests more rampant, and may also make the original pests that are not serious rise to become major pests.

Improper use of pesticides can kill some pollinators, which can affect seed setting and cause a serious reduction in yield.

First of all, it is necessary to choose the right pesticide according to the variety of crops, and at the same time, we must pay attention to the appropriate amount of pesticides when using them, do a good job of personal protection, and also avoid high temperature or heavy rain.

You can use the powder spraying method, which sprays the powder on the surface of the plant, you can use the watering method, which mixes the drug with water and sprays it on the roots of the plant, and you can also use the spray method, which atomizes the agent and sprays it on the surface of the plant with a machine.

It can be sprayed with pesticides, sprayed, or directly poured on the leaves, or smoked or fumigated, which are very effective.

First of all, you need to choose the right pesticide, you need to find the right pesticide, then you need to pay attention to the ratio of pesticides, pay attention to the validity period of pesticides, and then you can mix them in proportion, choose the right weather, the right temperature for spraying, and be sure to pay attention to the weather.

What is the knowledge of pesticide application methods? In the effective concentration range, and can exert the effect of pesticides, the pesticide concentration can be reduced for control. According to the disease, pest activity law and pesticide type, choose different application methods and application time.

Reasonable rotation and mixed use of pesticides can effectively improve the control effect of pesticides, but it should be noted that pesticides that decompose and fail in case of alkaline substances cannot be mixed with alkaline pesticides, fertilizers or alkaline substances, and pesticides that produce fertilizer reactions after mixing can not be used.

In order to control insect pests and rodents in the soil, the development of pests and pesticide use methods should be a reflection of the development of pesticide formulations. In other words, the emergence of a new method of use must be backed by a new pesticide dosage form. It is a mutually reinforcing and complementary rodent pest, and the stomach poison and pesticides are preferentially mixed in the soil, and the reasonable mixing of various pesticides can significantly improve the control effect.

In the actual process of Cordyceps control, we often find that multiple diseases, plagues or weeds occur at the same time. If we only use two or more pesticides in proportion and kill the disease according to different insecticide principles, or add a small amount of throwing or spraying granular insecticides. This can not be used to effectively improve the effect of pesticide control, reduce the resistance to crops and pests and diseases, and the application of pesticides on crops must be scientific.

Including the back of the leaves of the plant, so the control effect is better. The fumigation method is mainly used in small enclosed environments, which can easily cause damage to the drug. Therefore, it is necessary to master the correct dosage and use methods, strictly implement the technical regulations, and not change them at will, especially to control the drugs, ensure the quality of pesticides, and only use drugs in large doses.

Try not to mix pesticides indiscriminately or use the same highly toxic pesticide multiple times, and do not arbitrarily expand and choose the appropriate use of the convenient gold coin method. High-quality pesticides should only be used as species and modifications in combination with appropriate application methods.

Common methods of use of pesticides are:

1 Spray, spray.

2. Seed treatment, seed coating and seed dressing.

3. Fumigation, the use of smoke agent in confined space.

4. Soil disinfection Soil treatment.

5 furrow application for granules.

6 injections, for the number of gardens.

7. Powder spraying, used for a wide range of forest aircraft action or field powdering, now used less.

8 Accompanied by poisonous soil, it is used to destroy pests such as mole crickets on the surface.

9. Lose heart, mainly used for corn granules to control corn borer.

10. Soil burial, used for some endogenous pesticides to control tree borer pests.

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.

Pesticide users should be in accordance with the instructions and common problems indicated on the pesticide label, in the required application scope, target crops, drug concentration values, operation methods of guidance. Do not expand the scope and usage of the application, or change it to other operation methods.

Regardless of the type of pesticide, the concentration value or dosage of the pesticide needs to be moderate. Excessive dosage not only pollutes the environment, but also green plants are easy to cause fertilizer damage, the dose is too small, and there is no practical effect, resulting in the consumption of financial and material resources. On the basis of investigating and monitoring the natural environment, we decide the frequency of pesticide application according to the development status of pests and diseases, and we are never allowed to apply pesticides at will regardless of the condition of pests.

Take a look at the name, pay attention to the name of the relevant ingredient, the content and the preparation is not clear. The second look at the three certificates, that is, the pesticide registration certificate number, the product standard number, the production and manufacturing target selection and the identification of pesticides consistent with the label. Fourth, look at the net content, production date and expiration date.

The label should indicate the net content, expiration date, and date of manufacture (production lot number). Fifth, look at the logo and appearance. The content of pesticide labeling should be detailed.

It is best for people to wear goggles and protective masks, stand upwind, and often change hands to spray on the downwind side; When the main stem of the fruit tree is tall and large, in order to better reduce the frequency of back and forth, you can spray the upper and lower sides, and it is safest to spray and retreat while spraying. All in all, whether it is forward or degenerative spraying, people should stand in an advantageous position, which can greatly reduce the amount of pesticide intake and avoid accidental poisoning.

People who have done farming in the countryside know that the time to spray pesticides should not be selected in the morning, because in the afternoon, there are dew droplets on the food crops or vegetables and fruits, so the time to choose and apply pesticides is best from nine to eleven o'clock in the morning, and noon is best in the evening. The fourth point that we must pay special attention to is to be optimistic about the temperature. Before preparing to spray pesticides in advance, it is best to look at the weather forecast.

Be sure to apply pesticides around the temperature of rainy days, otherwise, after being washed by the rainstorm, the application of pesticides is also a failure, a waste of time, and a good opportunity to miss! Pesticides are also consumed.

Reasonable ingredient content: according to the percentage of content identification, the same drug name, the content is different, the dosage is different. Prevention Goals, Dosage and Method of Operation:

The prevention objectives of drugs need to be marked according to the scope of the pesticide control institute of the Ministry of Agriculture, and the dosage and operation methods should be realistic. For example, drugs used on cotton wool to prevent cotton bollworm cannot be used to prevent cotton bollworm on vegetables, fruits and other crops; The operation method can not be changed freely, and the pre-budding herbicide in the corn field is now applied, usually because the water demand is insufficient, the drug can not produce a film on the surface of the soil layer, and the drug power is reduced; The prevention of pests and diseases of fruit trees is also often reduced by insufficient water requirements.

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.

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.

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.

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.
