What do I need to pay attention to when spraying pesticides?

As we all know, the purpose of spraying pesticides is to make the planting items have a good effect, whether it is in the process of spraying pesticides, or long-term spraying of pesticides applicators when spraying pesticides, there are a lot of things that need to be paid attention to and paid attention to, if not dealt with, it is easy to cause harm, the following is introduced 5 precautions, I hope you keep in mind to avoid causing harm.

1. Wear long-sleeved tops, long pants, shoes and socks and wear masks when fertilizing; Don't smoke, drink, or eat; Do not touch your mouth, face, eyes, etc., and do not spray each other. If you want to drink water, smoke, eat, etc. after working every day, you must wash your hands thoroughly with soap or hand sanitizer, including important parts such as your face and eyes. Those who have the conditions can take a bath and change their clothes directly.

Second, spraying pesticide work clothes should be changed in time, the spraying time of the pesticide applicator is generally not more than 6 hours a day, and after 3 to 5 days of continuous application, a day of rest.

3. Patients with ** disease and other diseases that have not been cured, as well as women who are breastfeeding, pregnant, and menstruating, cannot spray pesticides. If the operator has symptoms such as headache, dizziness, nausea, vomiting, etc., he should immediately leave the site of pesticide application, take off the contaminated clothes, wash the exposed face, hands and other parts, and then go to the hospital immediately**.

Fourth, do not apply pesticides in windy and high temperature weather to avoid poisoning or pesticide damage to the personnel who apply pesticides. Especially when spraying pesticides in summer, it is necessary to reduce the concentration of drugs, because most pesticides will increase with the increase in temperature, and the efficacy of pesticides will be enhanced to a certain extent.

5. Do not use well water when spraying pesticides to avoid precipitation and affect the efficacy; Do not use sewage to dispense medicine, in case the nozzle is blocked, and the medicine will not come out; Do not fertilize with one medicine for a long time, do not use it continuously, to avoid drug resistance; Do not apply pesticides before picking to avoid residues of pesticides.

First of all, it is necessary to choose the right pesticide according to the crop, and then when spraying pesticides, we must pay attention to the concentration, and we should also pay attention to the spraying time.

When spraying pesticides, we must pay attention to the proportion and dosage of pesticides, we must prescribe the right medicine, do not mix casually, avoid chemical reactions, in the process of spraying pesticides, we must wear protective clothing, do a good job of personal protective measures, and avoid contact with **. Rainy and windy weather should be avoided, and it is best to choose sunny days to spray pesticides, so that the effect of pesticides will not be affected.

Care must be taken not to be too high in concentration, otherwise it may lead to the burning of the crops.

You need to be careful not to inhale into the body, but also pay attention to protect your face, when spraying pesticides, you should also pay attention to wearing masks, but also pay attention to do a good job of protection, and pay attention to wearing protective clothing, these are all safety that should be paid attention to.

Be sure to pay attention to personal safety, and when spraying pesticides, you must wear protective clothing, after spraying pesticides, you must close the door, you also need to leave this place in time, and you must choose the appropriate configuration method, but also pay attention to the wind direction.

It is necessary to do a good job of protection in advance, choose safe and pollution-free pesticides, do not pollute the land, choose the right concentration, and stay away from crowds.

We must choose the right pesticide for spraying, so that we can solve the actual problem, we must pay attention to the proportion, we must pay attention to the temperature, pay attention to the climate, and we must match according to the actual situation.

It is necessary to pay attention to safety issues, to pay attention to the concentration of spraying, to pay attention to the time of spraying, to be sure to choose a sunny day for spraying, to pay attention to the surrounding situation, and to choose the right pesticide for spraying.

First of all, it is necessary to choose the right pesticide according to different crops, when spraying pesticides, we must pay attention to the appropriate concentration, and we must pay attention to the time of spraying pesticides, to avoid high temperatures or rainy days, and to dilute with water in advance.

Before we spray pesticides, we must clean up some bad leaves, withered branches, and some broken branches in the fruit trees, clean them into a pile and burn them with fire, so that they can kill a lot of fungi, and can be used as organic fertilizer, and then spray pesticides, often the effect will be better。Don't underestimate this step, if you do this step well, then some insects and some fungi hiding in some dead leaves, or in some broken branches, are often easy to kill. <>

When spraying pesticides, it is necessary to grasp the active time points of these pests and diseases, and spray pesticides according to their active time points. If the pests and diseases are not active, it is difficult for us to spray pesticides to directly react to the insects, only when they are active, we spray again, then we can kill most of the insects. <>

If it rains when spraying pesticides, then you need to respray them. In fact, one of the most worrying things about spraying pesticides is rain, once it rains, the pesticides we spray are often easy to lose their efficacy. Pesticides are soluble in water, and when the rain washes them, it is very likely that some pesticides on the surface of the leaves will be diluted, which will affect the absorption of drugs by crops and reduce some damage to some insects.

Spraying pesticides is generally done at intervals of 3 to 5 days, up to a week, and a booster spraying is required. This step cannot be ignored, because a large number of germs and insects cannot be killed at one time, so it also needs to be strengthened once. Because the pesticides we spray at one time are not particularly comprehensive, if we can do it comprehensively without leaving dead ends, it will be better, but for the sake of insurance, it is still necessary to carry out secondary killing.

The dilution of pesticides is reasonable and compliant. Now pesticides will have a certain manual, according to their proportion, can not be more or less, more will be wasted, less money will not be effective.

You can also mix a little fertilizer or insecticide in pesticides, spray crops, spray crop roots, spray the land, and spray the leaves of crops.

First of all, it is necessary to choose the right pesticide according to the crop, and then choose the right location, and at the same time, you should also pay attention to the right time, do not choose to spray pesticides when the temperature or rain is relatively heavy, you must pay attention to the dose.

Because of the high temperature weather, due to the relatively high temperature, the water falling on the leaf surface of the plant is easy to evaporate, at this time, the spraying is easy to make the concentration very high, easy to produce pesticide damage, and also because the high temperature liquid evaporation too fast will cause waste. At the same time, due to the high temperature time, spraying pesticides in high temperature weather will speed up the decomposition of pesticides, and crops in high temperature weather, metabolism is relatively vigorous, and the agent is easier to enter the crop body, resulting in pesticide damage. It is also easier to cause heat stroke to sprayers.

The most important thing for pesticide mixing is to test its pH value, whether it is acidic or salty, if it is both acidic or salty, it can be mixed and sprayed together, otherwise, it can not be sprayed together. Generally speaking, in the environment of high temperature and scorching sun, it is easy to cause poisoning of pesticide applicators and crop pesticide damage, so it should be avoided to spray pesticides around noon in hot weather, even if high temperature has the effect of improving the efficacy of some pesticide varieties.

In general, it is not recommended to spray pesticides in farmland in hot weather. The risk of safety accidents caused by worker poisoning and fertilizer and pesticide damage to crops has also increased exponentially. However, in the actual production process, at present, the crops to be sprayed with pesticides in rural areas include rice, cotton, corn, soybeans, sesame, etc., but at present, the hot weather in June is not to work in the field, even if you stay at home and relax at every turn, you are sweating profusely.

Mineral oil spraying is more sensitive, and copper preparations are also sensitive; Spraying mineral oil must be done away from hot days. It is recommended to use organic copper in copper preparations, which will be relatively safe, but it is also necessary to reduce the dosage and mix more with water.

Medication temperature: Whether it is bacteria or some other plants, their most active temperature is generally about 25°, at this time the medication is the most appropriate, because they are more active at this time, and the effect of the medicine is better when spraying. Improve the utilization rate of pesticides and pay attention to increasing the adhesion of pesticides.

When using pesticides in open crops, it is more appropriate to choose rain-resistant erosion, emulsifiable concentrate, etc., these pesticides remain on the surface of the plant for a long time, and powder, water agent, etc. are relatively poor.

After the liquid sprayed from the nozzle is deposited on the target, it needs to form a uniform film to cover the surface of the target to the greatest extent, and then kill the pests and diseases on the target. The deposition of the chemical solution will be affected by a variety of factors, among which the air humidity is greatly affected.

When spraying, do not spray directly on the crop itself, be sure to spray it around at a certain distance. And also choose the corresponding pesticides. In this way, it can effectively defend against pests and diseases.

And after spraying, it should also be watered in time to help our crops better absorb nutrients.

When spraying, you can spray back and forth, be sure to spray evenly, be sure to pay attention to the back of the leaves also need to be sprayed, pay attention to your own spraying situation, and choose the right watering can for spraying.

Be sure to spray evenly, but also pay attention to the scope when spraying, but also to dilute it appropriately, try to choose pollution-free pesticides, and try to choose pesticides that are not very harmful.

Pay attention to the spraying cartridge before spraying as much as possible, especially after spraying herbicides, and then spray insecticides or fungicides must be cleaned, if possible, you can buy an extra cartridge to spray herbicides or insecticides, spraying time as far as possible after 3:30 p.m. on a sunny day or cloudy day, to promote the effect of the drug and prevent poisoning. Do not spray in rainy days, if it rains after spraying in the open air, you need to spray after sunny days.

Before spraying, pesticides must be prepared in accordance with instructions or guidance dosages. In the large-scale development of diseases or plagues, mixed spraying agents can be selected, such as inhaler insecticides and contact insecticides, which can improve the control effect. You need equipment to spray pesticides.

If a worker wants to do something, he should first sharpen his tools. We need to carefully inspect all parts of the pesticide spraying device for gases or cracks to avoid the risk of pesticide seepage**.

When spraying pesticides, farmers must pay attention to pesticide instructions, understand the control objects, see the reasons for pesticide dilution, and know how much drug to spray per acre! More plants are easily destroyed by drugs, while fewer plants have no effect. This is key and also depends on the time.

It's best to spray the medicine in the morning and evening. If it rains within four hours of spraying, you have to spray again. First of all, when spraying pesticides, farmers must pay attention to themselves and protect themselves first, which is the most important thing.

Although there are no highly toxic pesticides, some pesticides are corrosive to the body. Especially in summer, when the weather is hot and a large amount of ** is exposed, special attention should be paid to the body when injecting.

For example, ground tigers should be used before planting and when cultivating the target land. Fungicides are divided into bacteria and fungi, pesticides should be applied according to the vegetable crucible, according to the proportion of vegetables, first of all, the number of insects in the vegetables should be observed, the dosage should be adjusted appropriately, and the pesticide brand should be noted. If the wrong pesticide is sprayed or too many pesticides are sprayed, it can cause a lot of damage to the crop.

It should be applied in the absence of wind and dew.

You should pay attention to the time of use, that is, when using pesticides, you should also pay attention to the composition of pesticides, you should pay attention to the ratio of pesticides, try not to choose a variety of pesticides mixed together, and you should also pay attention to personal protection when using pesticides.

1. Pay attention to the time of use, 2. Pay attention to the spraying method, 3. Pay attention to adding water, 4. Pay attention to wearing gloves and masks to protect your safety.

It is necessary to grasp the concentration of pesticides, pay attention to the time of spraying, but also grasp the frequency of spraying, and also check crops regularly to do not abuse pesticides.

Pesticides can be said to be an indispensable item in the process of agricultural work. In the process of crop growth, many situations will occur, such as insect pests such as various diseases of crops will have a great impact on the yield of crops, but the spraying of different pesticides can not only prevent insect pests and diseases of some crops, but pesticides are also harmful, although today's pesticides are diluted with water after the balance of the solution, the risk of poisoning has been greatly reduced, but because the sprayed pesticides are atomized liquid is easy to drift to people's eyes, The mouth and nose are also relatively harmful. And most of the modern way to spray pesticides is to use a knapsack hand pressure sprayer, which is easy to leak night after a long time, and has a certain corrosiveness to people's hands or other parts.

First of all, the problem of night leakage is relatively common in rural areas, because the safety awareness of farmers is not very high, and can not have a good maintenance of the sprayer, it is easy to cause the phenomenon of night leakage, it is not difficult to solve this problem, only need to pay attention to the gasket problem at the interface of each part before use, it can effectively avoid the occurrence of similar situations.

The harm of atomized liquid medicine to the human body is the most direct, because in the process of spraying pesticides, people have the most contact with atomized liquid medicine, and people's eyes, mouth and nose are particularly sensitive parts, and it is easy to have some problems after being contaminated with these liquids. The best way to solve this problem is to wear a mask and goggles when spraying pesticides, which can avoid damage to key parts of the human body to a certain extent.

If the modernization of society is developing more and more rapidly, it is believed that in the near future, spraying pesticides will be replaced by mechanization, which can not only greatly improve the efficiency of spraying pesticides, but also reduce the harm to people.
