How do you use pesticides to ensure they work optimally?

There are many types of pests, some of which are mainly active in the morning and some are mainly active in the evening. So based on this, our spraying time should be carried out after 9-10 o'clock and 16 o'clock. Because after 9 o'clock, the dew on the crops has gradually dried up, and this is also the time when the sunrise pest activity is at its highest.

Therefore, if you use the medicine at this time, you can let the pests directly contact the liquid medicine and improve the efficiency of insecticide. After 16 o'clock, the ultraviolet rays in the sun decrease, and the temperature gradually drops. And it is also the active period of nocturnal pests, and at this time, medication can effectively control nocturnal pests.

There are many types of pests, and there are also different types of mouthparts. The first is the chewing mouthparts pest, which mainly feeds on the roots, stems and buds on crops. Pests with piercing and sucking mouthparts feed mainly on liquids from crops.

Therefore, if we want to improve the effectiveness of insecticide control, we also need to choose drugs according to the mouthparts of the pest. For example, contact killers, systemic agents, etc., in the prevention and control of stinging and sucking pests, an appropriate amount of penetrant can be added to pesticides, which can effectively improve its control effect.

Pests also have different damage to crops. For example, underground pests mainly damage the roots of crops and the stems of the ground. Therefore, when we control underground pests, we can spread pesticides on the ground, and then carry out deep ploughing and tillage, and fully mix the pesticides with the soil.

At the same time, it can also be irrigated near the roots, or made into poisonous bait and applied between crop rows for control. For gnawing pests, it is necessary to spray and control stomach poisons and contact killers.

When using pesticides, be careful not to use a single pesticide for a long time. Failure to do so will lead to increased pesticide resistance and the offspring produced by adult mating will be even more resistant. Therefore, when we use medicine, we should rotate the drug to avoid pests becoming resistant.

Then it can also be mixed according to the characteristics of pesticides, adding an appropriate amount of synergist, which can improve the drug properties, enhance its insecticidal effect, and also prevent pests from showing resistance. Finally, when we choose pesticides, it is best to use biopesticides with high efficiency, low toxicity and low residue.

When using insecticides, you should spray them in the corners of the room and in damp places to have a good effect.

When using insecticides, you should choose the right agent, for pests to prescribe the right medicine, not any insecticide has a certain effect on any pest, when using insecticides, you should reduce the amount of pesticides, increase the number of drugs, according to the climatic characteristics and the day and night activity of pests, choose a favorable time to apply pesticides.

Pay attention to the location of the spraying, be targeted, do not spray indiscriminately, and also pay attention to the time of spraying, it is best to spray at the egg stage.

After the insecticide enters the respiratory tract, it may cause serious upper respiratory tract infection, dizziness, nausea and gastrointestinal reactions. When using insecticides, first of all, people can not stay in the house for a long time, you can add insecticides, spray them in the room and close the doors and windows, and then people quickly evacuate, and wait until a period of time for rapid ventilation.

Generally speaking, household pesticides are not very harmful to the human body, but insecticides are also a mixture of chemical raw materials. Try to avoid food and the human body.

I don't think it's much of a harm to people, and the house should be sealed up, then insecticide, and still in after an hour of ventilation.

I don't think it's very harmful, just use pesticides and then ventilate the house and it won't have much effect on people.

Everyone knows that when there are some pests and diseases in the crops, the farmer will choose to use some pesticides to save his crops. And for some fields, there are actually a lot of insect infestations, so it is necessary to use pesticides when necessary. But if people don't use pesticides scientifically, it is likely to harm their crops.

So what we are going to talk about today is how to use pesticides scientifically and rationally in life.

Symptomatic medication is first of all when using insecticides, because there are actually many types of pesticides. And each pesticide has a specific control object and its scope of use, so when using it, we must understand the object of use in order to accurately choose insecticides. If the right pesticides are not used, even if they are sown, they will not achieve the desired effect.

Therefore, when using insecticides, you must use symptomatic drugs to solve your own problems.

The second thing is to use pesticides appropriately, because when you decide to use pesticides, you already have a very clear diagnosis of pests and diseases. Therefore, at this time, it is necessary to find a suitable time to use insecticides, so that we can accurately grasp the dynamics of pests and diseases and accurate insecticide. So if it is an insecticide to control fruit insects, then there will be some pest eggs on some leaves on the fruit tree at this time.

Therefore, this problem also needs to be taken into account when killing insects, so that it can be carried out.

The final scientific use of pesticides is to carry out scientific use of pesticides, because there are actually many types of pesticides. So no matter what medicine you choose, you must choose those effective methods and convenient methods to use. Moreover, when using insecticides, the concentration should not be too low or too high, and it must be sprayed evenly when spraying, so as to accurately eliminate pests.

First of all, the symptomatic medication should be used, and then it should be used at the appropriate time, and the drug can be rotated to reduce drug resistance.

The best way to use pesticides scientifically and rationally is to pay attention to the time and amount of use, and pay attention to the seasonal use, so that they can be used very well.

First of all, it is necessary to choose the right insecticide according to different insects, and then it is also necessary to choose the right insecticide according to different crops, and it is necessary to do a good job of dilution before use, and it is necessary to master the efficient use method, and also need to do a good job of personal protection, and it must be particularly uniform when spraying.

Insecticides are a special commodity with a wide variety, so pay attention to the following when purchasing:

1.Do not purchase insecticides that are not labeled as active insecticidal ingredients. Do not purchase insecticide products that are processed and produced with pesticides that have been banned from use.

2.When aerosol insecticides and other products leave the factory, they must strictly implement the three-certificate system of marking the quasi-production certificate number, the insecticide registration certificate number and the product quality standard number, otherwise it is an illegal commodity and must not be purchased.

3.Among the chemical insecticides, pyrethroid insecticides are generally considered to be safer, and permethrin, methrin, allethrin and deltamethrin are generally safer. Organochlorines, organophosphates, and carbamate are less safe.

Pay attention to the following when using:

1.The use of pesticides should be used sparingly as much as possible, and when not in use, try not to use them. When using spray pesticides, it's a good idea to wear a mask. Minimize contact with pesticides, such as not staying in the house where the pesticide is applied, leaving immediately after application, and opening doors and windows to fully ventilate and exhaust before entering.

2.Do not spray pesticides directly at people and pets. Avoid exposure of infants, children, pregnant women and people with specific allergies to pesticides to avoid adverse effects.

Do not spray pesticides on food, utensils, furniture and bedding when using pesticides. Keep pesticides safe and out of reach of small children.

3.Bathe and change clothes after applying insecticides and insecticidal creams.

4.Spray insecticides should not come into contact with open flames to avoid occurrence**.

5.Long-term use of one insecticide can make mosquitoes, flies, and cockroaches resistant, and if you are not satisfied with the effect, you should switch to another insecticide or choose another brand of insecticide products.

There are two types of commonly used pesticides: biological pesticides and chemical pesticides, and the specific use methods are shown in the following table

When using pesticides, the natural enemies of pests should be consciously protected and the use of non-selective pesticides should be avoided as much as possible. At the same time, the continuous use of a single insecticide should be avoided to enhance pest resistance and weaken the control effect. It is recommended to alternate the use of biological pesticides for pest control.

1. When using spray insecticides, check whether the cartridge has the words "no Buddha Ang", the date of manufacture, the shelf life, and the approval number of the health department.

2 Use spray insecticides in moderation, if sprayed too much, it will pollute the living environment and cause headaches and other symptoms.

3 When using spray insecticides, it is best to wear a mask, do not spray on food, utensils, furniture, and bedding.

4 Do not approach an open flame to avoid **.

5 After spraying, the doors and windows should be closed as soon as possible, people should not stay indoors, and then open the doors and windows after about half an hour to make the room. Turn it on again after about half an hour.

One press"Flutter", and the potion came out.

The correct way to use household pesticides should be:

For flying insects such as mosquitoes and flies, direct spraying should be directed at the target pests; Or close the doors and windows, spray in all directions of the space at will, so that the room is filled with mist, mosquitoes and flies and other flying insects can die within a few minutes, keep 10 30 minutes after opening the doors and windows for ventilation, and wait for the indoor insecticide smell to dissipate before entering the room.

For cockroaches and other reptiles, the aerosol should be evenly sprayed on their infested, staying, and perching places, and in order to maintain the long-lasting effect, it should not be erased after spraying.

When using household pesticides, the following must be noted:

All food, water, and cupboards must be sealed before spraying spray; It is best to use it after people have eaten to avoid contamination. Keep the agent out of the reach of children.

Protective protection should be done, preferably wearing long-sleeved clothing and a mask with household insecticides to prevent ** or respiratory poisoning.

Do not overdose. Many people increase the dose to enhance the insecticidal effect, but this can also lead to poisoning.

4.If you find that your family members have symptoms such as dizziness, nausea, blurred vision, and stinging, you should leave the environment where insecticides have been used in time, and if it is serious, you should send it to the hospital in time. Since insecticidal aerosols are pressure-packed, they should be protected from violent impacts and cannot be stored in high-temperature environments.

5.Do not spray it against a fire source to avoid danger.
