Why can t some pesticides be sprayed with a fogger?

The fine particles produced by the spraying of the mist machine have strong penetration, and can directly pass through the canopy of the plant to kill insects and bacteria, leaving no dead ends. The effect is longer, and the tiny drug particles can float in the air for 2-8 hours, making the effect longer. According to these characteristics of the fogging machine, it is most suitable for spraying fungicides, not suitable for spraying foliar fertilizer, and the foliar fertilizer concentration is large and easy to burn leaves.

1. It cannot be used for cotton spraying arthromine and chlormequatin. Reason: Cotton control products are sprayed on the top of the plant, and a small amount is used many times, the purpose is to shorten the internode distance, make the column compact, shape the tower structure, and facilitate cotton ventilation and photosynthesis.

Due to the height of the cotton plant, most of the spraying of the mobile fog machine is in the middle and lower parts, which is counterproductive, so it cannot be used.

2. It is forbidden to spray highly toxic and highly toxic pesticides such as phosphine and carbofuran to avoid poisoning of operators.

3. It is forbidden to use herbicides such as paraquat or glyphosate in weeding between crop rows. The mobile fog machine atomizes finely, and it is easy to drift to crops to produce pesticide damage, etc.

Working principle of motorized fog dispenser: use high-pressure airflow to drive the liquid medicine to spray out the mist 1It cannot be used to spray arthromine and chlormequat in cotton Reason:

Cotton control products are sprayed on the top of the plant, and a small number of times The purpose is to shorten the internode distance, make the column compact, shape the tower structure, and facilitate cotton ventilation and photosynthesis.

2.It is forbidden to spray highly toxic and highly toxic pesticides such as phosphine and carbofuran to avoid poisoning of operators;

3.It is forbidden to use herbicides such as paraquat or glyphosate to use motorized mist dispensers to remove weeds between crop rows, which can easily drift to crops and cause pesticide damage.

One is the powder spraying method. It is a method of blowing low-concentration or diluted pesticide powder with dry fine soil onto the surface of crops and control objects by using the wind generated by machinery. Pros:

The operation is convenient and the tool is relatively simple; High work efficiency; No need for water, no water source restrictions; It is generally not easy to produce pesticide damage to crops. Disadvantages: the powder is easy to be blown away by the wind and washed by rain, therefore, the amount of powder attached to the crop surface is reduced, the residual effect period of the agent is shortened, and the control effect is reduced; The unit consumption is large, and it is not as cost-effective as spray in terms of economy; Polluting the environment and the applicators themselves.

The second is the spray method. Pesticide preparations such as emulsifiable concentrate, milk powder, suspension, soluble powder, water agent and wettable powder, after mixing and modulating a certain amount of water, can form a uniform emulsion, solution and suspension, etc., and use a sprayer to form tiny droplets of the liquid medicine and then spray it on crops or diseases, insects and weeds. The size of the droplets depends on the spray water pressure, the size and shape of the nozzle aperture, and the size of the vortex chamber.

In general, the greater the water pressure, the smaller the nozzle aperture, and the smaller the vortex chamber, the smaller the diameter of the atomized droplets. Before the 50s of the 20th century, large-volume spraying was mainly used, and the amount of spraying solution per 667L 12 was greater than 50L. However, in the past 10 years, spray technology has developed greatly, mainly after the ultra-low volume spray technology has been popularized and applied in agricultural production, the amount of spray liquid has developed to a low volume trend, and the amount of spray solution per 667L m2 is only O 1 2L.

At present, foreign countries with more developed industries mostly use small-volume spraying methods, because they have many advantages: good spreadability and uniformity, less amount of medicinal solution, less labor, less mechanical power consumption, high work efficiency, good control effect, and high economic benefits. The disadvantage is that there is a need for a good water source and high requirements for water quality.

Hello? For your information:

1. Check whether there is water in the sprayer. (whether the amount of water is sufficient).

2. Check whether the sprayer has pressure. (Connections everywhere).

3. There is no pressure to check whether the piston falls off. Fourth, check whether the switch is blocked.

5. Check whether the nozzle is blocked.

6. Check whether the sprinkler head is blocked.

7. Whether the longitudinal beads are installed when disassembling and assembling the piston cylinder liner assembly.

8. Whether the transverse beads are installed when disassembling and assembling the piston cylinder liner assembly.

9. If the above overhaul is fruitless, it is recommended to send it for repair.

Thank you for your question.

Nozzle adjustment, if it still can't be atomized, it is a problem of pressure, the pressure valve is broken, you can take it to repair, repair is generally about 12 pieces of pressure valve, and the famous brand is expensive.

Generally, the nozzle of the sprayer is adjustable, and after you adjust it forward and reversely, try it separately to see if it can solve the problem. If it doesn't work, it should be good to change the nozzle!

It should be the issue of the nozzle of your sprayer.

Summary. Hello, no, the use of fogging machine is not harmful to crops, and there is no damage to the effect of pesticides. 1. The fog dispenser can make the atomized particles more subtle, diffuse evenly, and has the advantages of long spray distance, good penetration, and wide use.

Apply pesticides in Daejeon.

Hello, no.

Hello, pesticide into spray is made by dissolving the pesticide in an appropriate solvent and then making the squire to spray the solution evenly on the crop with a sprayer. First of all, select a suitable solvent to dissolve the pesticide. Different pesticides may require the use of different solvents, so the choice needs to be based on the properties of the pesticide.

Commonly used solvents include water, ethanol, acetic acid, etc. Second, pesticides are added to the selected solvent. According to the dosage requirements of pesticides, the pesticides are gradually added to the solvent and stirred evenly until the pesticides are completely dissolved.

Then, pour the pesticide solution into the sprayer. Carefully pour the dissolved pesticide solution into the container of the nebulizer to ensure that it does not spill or waste. Finally, use a sprayer to spray the pesticide solution evenly on the crop.

Adjust the concentration and scope of spraying according to actual needs to ensure that the crop is evenly covered. It should be noted that when using pesticide sprays, you should follow the instructions for the use of pesticides and safe operation specifications to protect your health. In addition, pesticide spraying should be carried out under suitable weather conditions, and avoid being used when the wind is too strong or rain, so as to avoid the pesticide being blown away or washed away.

In addition to turning pesticides into sprays for spraying, pesticides can also be applied in other ways, such as spraying, irrigation, spreading, etc. Different application methods are suitable for different crops and pesticide types, and can be selected according to the actual situation. However, no matter what method is adopted, it is necessary to pay attention to the correct use of pesticides and environmental protection to ensure the healthy growth of crops and the safety of humans and animals.

Summary. Dear, I'm glad to answer for you: what happens if you use a sprayer with a stirring function to spray pesticides: spraying pesticides with a stirring function will make the spray concentration more balanced, the dissolution of the agent more evenly and the effective area can be sprayed and distributed on crops.

Dear, I'm glad to answer for you: what happens if you use a sprayer with stirring function to spray pesticides: sprayers with stirring function will make the spray concentration more balanced, the dissolution of the agent more evenly and more effectively spraying and distributing on crops.

It can be sprayed evenly. Precautions for spraying The nozzle should not be close to the seedlings, pay attention to their own safety, operate correctly, stand in the upper hand, and stir the pesticide evenly. However, spraying pesticides should pay special attention to personal protection, spraying highly toxic pesticides must wear protective clothing, because highly toxic pesticide mist floating on the operator may always occur the risk of pollution poisoning, especially the nose, eyes, mouth and other particularly sensitive parts, must be protected.

The problem of dripping of the liquid medicine that occurs during spraying must also pay attention to stirring evenly when mixing the medicine, and adjust the nozzle to make the sprayed liquid atomized as much as possible. To wear anti-bridge protective equipment, the sprayer nozzle should keep a certain distance from the crop when spraying, and it is best to stand on the upper hand when it is windy.

The following points should be paid attention to in the pesticide preparation process:

1) Accurately verify the pesticide application area, and calculate the dosage and application solution according to the pesticide dosage recommended by the pesticide label or the recommendation of the plant protection technician.

2) Operate in a sheltered place and accurately measure pesticides with special weighing instruments.

3) All weighing instruments should be cleaned after use, and the flushed waste liquid should be properly disposed of away from residences, water sources and crops. Vessels used for measuring pesticides shall not be used for other purposes.

4) After measuring the pesticides, close the original pesticide packaging and store it safely. Pesticides should always be kept in their original packaging before use.

5) The preparation of pharmaceutical liquid should be carried out in a place far away from water sources, residences, and livestock pens.

6) It should be used and matched, and should not be stored for a long time; When stored for a short time, it should be sealed and arranged to be kept by a special person.

7) The amount of pesticide application solution should be determined according to different application methods and control objects, fruit tree species and growth period.

8) Pesticides should be prepared with clean water without impurities, and water should not be taken directly from pesticides.

9) Pesticides should be prepared according to the pesticide dosage form and the method recommended by the pesticide label.

10) Dilution should be carried out by the "secondary method": Pesticides diluted with water: first dilute the pesticide formulation with a small amount of water into the "mother liquor", and then further dilute the "mother liquor" to the required concentration.

Pesticides diluted with solid carriers: A small amount of dilution carriers (fine soil, fine sand, solid fertilizers, etc.) should be used to evenly dilute the pesticide preparation into "master powder", and then further diluted to the required amount.

11) The preparation of pesticides for immediate use should be operated in accordance with the provisions on the pesticide label or under the guidance of technical personnel.

The use of chemical pesticides to control sunflower diseases, insects and weeds is a necessary measure in agricultural production. On the basis of mastering the performance of pesticides, the following principles must be paid attention to in order to use pesticides scientifically, reasonably and safely.

1) Symptomatic and timely medication. According to the types of sunflower diseases, insects and weeds and the occurrence of diseases, insects and weeds, different types of insecticides, fungicides and herbicides were selected. Different pesticide varieties have different control effects on different control objects.

Before applying pesticides, we must carefully investigate the diseases and cordyceps, and apply pesticides in the best prevention and control period to achieve symptomatic medication. Generally, it is chosen in the early stage of the occurrence of Cordyceps to achieve timely prevention and control.

2) Ensure pesticide application technology and quality. Pesticide application to choose quality assurance spray equipment, accurate weighing of pesticides, this is an important part of the prevention and control of pests and weeds, must be according to the pesticide instructions to take pesticides, can not increase the amount of pesticides, especially herbicides, to avoid waste and pollution to the environment, agricultural products. Do not use a single pesticide for a long time, and mix pesticides scientifically and reasonably to delay the emergence of resistance to Cordyceps.

3) Pay attention to safe medication. Ensure safe intervals and scientific application of pesticides to avoid human and animal poisoning. Pay attention to the cleaning of pesticide application equipment, and use water to dispense.

At present, some herbicides used in production are ultra-efficient, and once a certain type of pesticide remains in the application device, or the water used to prepare the pharmaceutical solution is contaminated by a certain type of pesticide, it is easy to cause pesticide damage to sensitive crops.

4) Ensure the quality of pesticides. It is noted that the regular pesticide sales department purchases pesticides with three certificates.

(1) Before application, the application equipment should be carefully inspected to prevent the liquid medicine from running, rising, dripping and leaking.

2) The amount of water added should be according to the standard, the walking speed should be consistent, and the fog droplets of the nozzle should be uniform, and no respraying or leakage should be sprayed.

3) Spray crop fields with dense canopy, using high-pressure or air-fed spraying equipment so that the droplets can pass through the canopy.

4) Under the climatic conditions of high temperature and strong wind, avoid spraying too fine to prevent drift pollution, and pay attention to sensitive crops planted in adjacent plots.

5) Plots that have been applied with pesticides, especially plots with highly toxic insecticides, should be marked in obvious places to prevent people and animals from entering the pesticide application environment and causing poisoning accidents.

When spraying on vegetables, there will be no pesticide damage. The main reasons are as follows:

1. The atomization particles of the fog machine are fine and evenly diffused, which is the most ideal supporting machinery for the development of green pollution-free vegetables.

2. In the control of vegetable insect pests, the use of mist spraying has the advantages of high efficacy and good control effect. However, due to the use of mist machine spraying water consumption is small, the concentration of liquid medicine is high, and the formation of high concentration and very small particles of medicine mist around the machine, if the operation is improper, it is often easier to cause pesticide poisoning of the operator, or overdose in local areas, so that the crops suffer from pesticide damage. Therefore, it must be used correctly to improve the spraying effect, and the correct use method is described as follows

1) Add water first, then add medicine. ensure that crops are not damaged by pesticides;

3), spraying weather: the climate is too dry spraying effect will be affected, should try to choose no wind, after rain, dew, fog, humidity weather spraying. Summer:

In the hot Guanzhong area of Shaanxi, it is generally better to choose 5 o'clock in the morning - 7 o'clock in the morning, and it is better to spray after 8 o'clock in the evening; Autumn: 6 o'clock in the morning - 10 o'clock in the morning, after 4 o'clock in the afternoon, if there is no wind in the cloudy day, you can spray the medicine all day, try to avoid spraying under high temperature and strong light, you will not see the atomization under the high temperature and strong light, you will feel that the atomization is not good and the spray is more and waste the liquid.

4) Finally, it should be noted that you must do a good job of personal protection when spraying, masks must be worn, and it is best to walk backwards to reduce pesticide pollution;

3. The range of the fog machine is high, the flat spray covers a large area, and the spray fog can reach more than 8 meters. Moreover, the liquid medicine has small particles and strong penetration, which greatly reduces the amount of medicine, and will not cause damage to vegetables if it is operated properly.

Hope mine helps you!
