How to use pesticides safely and rationally in facility agriculture?

How to use pesticides safely and rationally in facilities because of the high room temperature, high environmental humidity, weak sunlight exposure, and poor natural ventilation, diseases are easy to occur. The organic chemical control has remarkable results, fast results and easy to use, and has irreplaceable effects in ensuring the production and manufacturing of vegetables and fruits in greenhouses. In order to make full use of the advantages of organic chemical prevention and control in production and processing, get rid of the environmental pollution and residual problems caused by it, and ensure the safety and rational use of pesticides, we should start from the following levels:

All kinds of pesticides are used symptomatically, and they have certain prevention and control goals. When preventing and controlling, appropriate pesticide types should be selected according to certain control objectives. For example, trichlorfon is used for the prevention and control of biting mouthparts, promethine is best used for the prevention and control of loofah black spot, it is best to use powdery rust or banlin for the prevention and control of downy mildew, methamethamine and disinfection alum are used for the prevention and control of downy mildew, and the bud insects other than melon aphid and cotton aphid are animated with special effects to avoid aphid fog.

Moderate use of drugs should be based on the regularity of the prevention and control objectives, the characteristics of the pesticides applied and the results of the analysis and reporting, and grasp the weak points of the prevention and control objectives and use drugs immediately. If the prevention and control of borrowing insect pests should be used during the incubation and maturity of eggs; The control of general insect pests should be used before the third instar; The application of pesticide fungicides to prevent and control crop diseases and pests should be used before the pathogenic bacteria have not invaded the crops. The center of the disease can be partially closed first, and the pests and diseases produced by the tracing piece can be selected and treated first.

To improve the quality of medication, the first is to use a moderate amount of medication, not the more the better. On the basis of ensuring the actual effect of prevention and control, the minimum reasonable concentration value and at least reasonable frequency should be applied; The second is to select effective medication methods. Because the greenhouse has the characteristics of being sealable, the application of fumigation method has a good effect.

No matter which methods are used, it is necessary to ensure that the medicine is seen and the medicine is evenly proportioned.

In order to better improve the actual effect of pesticide control and avoid environmental pollution of vegetables and fruits and the formation of pests and pests due to the application of pesticides, the alternate application of pesticides with different mechanisms of action is an important way to improve the efficacy. There are four commonly used ways of cross-application of pesticides in manufacturing: one is the cross-application of microbial pesticides, mineral-derived pesticides, and organic chemical pesticides.

For example, in the production and manufacturing of Chinese cabbage, Bt solvent, rotenin, chlorpyramide, centarethrin, and trichlorfon can be cross-applied; The second is the cross-application of protective film and systemic agent. For example, in the prevention and control of cucumber downy mildew, before the disease, the protective film agricultural streptomycin, iprodione, mancozeb, etc. are the leading, and after the gradual onset of the disease, the systemic type of pric, methamethyl, and pleiotropin are the dominant ones, and they are cross-applied; The third is the cross-application of spray and fumigant.

Try to choose a wide range of pesticide spraying area, and pay attention to the hazards of pesticides, before using pesticides, we must learn to dilute, and pay attention to the potential safety hazards of pesticides.

When using pesticides, you must read the instructions, and at the same time, you should dilute them, so that they are safer and the area used will be larger.

Be sure to use it under professional guidance, don't use too much when using, pay attention to the concentration of pesticides, and pay attention to the scope of spraying.

When using pesticides, we try to dilute the pesticides as much as possible, because only in this way can we be better, and at the same time, we can be better and better solved.

When spraying pesticides, first of all, we must be fully armed, and we must put the pesticide tube on the ground, so that it will not be sprayed everywhere, and we will not inhale poisonous gas, and at the same time, the spraying will be very even.

When applying pesticides, be sure to dilute them in advance, and when using pesticides, users should wear goggles, gloves, and masks, which will be safer.

It is important to dress neatly, and then preferably wear a protective mask, so that it may be safer to spray pesticides. Because after pesticides enter our body, it is likely to bring harm to our body.

First of all, before using pesticides, we must understand the instructions, we must wear protective clothing when spraying pesticides, we must wear goggles when mixing insecticides, and we should also pay attention to the storage of pesticides, liquid pesticides must pay attention to heat insulation, do not put them in places where children can get them, do not spray pesticides in windy, high temperature, and rainy weather, which will affect the effect of pesticides.

It is to use it in accordance with the scientific instructions, not to overuse, and not to add some other pesticides, dilute according to the required proportion, and then spray.

With the continuous development of social economy, we will encounter a variety of problems in real life, especially for the scientific use of pesticides, how to use pesticides safely, but also make many friends very puzzled by this, in fact, we want to talk about the glory as a high-risk product safety, it is definitely a very noteworthy thing, so we must be equipped with special appliances when we use pesticides safely.

First of all, we must understand such a problem, that is, scientific, the rational use of pesticides is very correct, and can protect our human body well, can make us more safe in the process of spraying pesticides, we must pay attention to protect ourselves when spraying pesticides, we must wear masks, and to choose the correct dosage of the matching dispensing, only in this way can we better protect ourselves, but now some places have been able to use drones to spray pesticides, Then we can also spray directly with drones, so that we can ensure our safety to a large extent.

In addition, we must also know that in order to be able to better use pesticides scientifically and rationally, when we use pesticides, we must abide by the corresponding principles and conditions of use, and must not buy some highly toxic, highly toxic, high residue pesticides to spray, in the process of spraying, we must pay attention to the situation of good reflection, we must pay attention to protect our personal health. When spraying pesticides, you should wear the corresponding protective and matching masks, and protect your health through scientific means, no matter what, these things must be known.

To sum up, we can obviously know that scientific spraying of pesticides is a very correct way, and can help us solve many problems, so we must pay attention to these related problems in the process of spraying pesticides, only in this way can we better help ourselves.

The first thing is to buy the pesticide back, be sure to follow the instructions on the pesticide, and then go to mix with water. There is also the need to meet the relevant ratios. And pesticides can't come into direct contact with your **.

When applying pesticides, it is best for the parties to wear masks and gloves, and in the process of use, they should be far away from the person's face, and choose to spray evenly and apply them evenly.

To choose green pollution-free pesticides, but also to grasp the concentration of pesticides, pay attention to the scope of spraying, to stay away from water sources, but also to do a good job of protective measures.

When using pesticides, we must take corresponding protective measures, and we must use pesticides in accordance with the regulations, so that it will be safer.

First of all, it is necessary to choose the right pesticide, and should also pay attention to the efficacy, but also should pay attention to the shelf life of pesticides, and should also do a good job of personal protection, and when the temperature is particularly high, or when it is windy on a rainy day, try not to use pesticides, and do a good job of ventilation and watering.

In daily production, due to the improper use of pesticides, or even the abuse of pesticides, accidents such as crop injuries and human and animal injuries often occur. Therefore, it is necessary to grasp some knowledge of safe and reasonable pesticide use in time. The key to achieving good control results is to select pesticide varieties for different crops, different diseases and insects, and different forages.

Otherwise, not only the effect is poor, but also the pesticide is wasted, the time for prevention and control is delayed, and the loss of agricultural production is caused.

Farmers must make correct choices and use of pesticides in order to ensure that pesticides can effectively control pests and diseases, so that agricultural production can be carried out in an orderly manner. Farmers must pay attention to choosing the right variety and use time when using pesticides to achieve better expected results. Specifically, there are two situations in the use of pesticides, that is, when there are many crop pests and diseases in the local area, and they need to use them, the local pesticides are used to deal with pests and diseases.

Therefore, when farmers use pesticides, they must understand the pesticide manufacturers at the place of use, so as not to mistakenly choose pesticides that will have an adverse impact on themselves or themselves. Do not mix pesticides with other pesticides when using pesticides. If pesticides are mixed with other pesticides, there is a high risk that they will have bad consequences for people.

Although some pesticides do not cause adverse effects on one's own body when used, they can have an impact on agricultural products.

Therefore, farmers must pay attention to the following matters when using pesticides: first of all, the selection of pesticides should be determined according to the growth habits of crops, growth and development laws, the general environment of the region and other conditions, and the impact of pesticides on the environment. For example, temperature and humidity have an important impact on the occurrence and development of diseases, insects and weeds.

There are many methods of pesticide application, such as spraying, sprinkling, bandaging, dipping, soaking, seed dressing, etc., each with its own scope of application and mode of action. Sixth, it depends on the dosage, some pesticides need to be used continuously for several days to produce resistance, some pesticides need to be used for several days to produce resistance, and some pesticides may need to be used continuously for several months to produce resistance.

First, put pesticides out of reach of children, second, choose pesticides according to the type of pests and diseases, third, use them according to instructions, fourth, the concentration should be appropriate, and fifth, choose the right weather.

Agriculture is inseparable from pesticides, there is no doubt that the rational use of pesticides has become a profound knowledge, and there is no unified standard, the dosage of various places is related to their own experience, in general, the use of pesticides, the first is to diagnose the first pest, the second is to spray drugs according to the season, try to choose low toxicity, volatile, less residue, or biopharmaceutical! While pursuing the product effect, we should also consider health and environmental protection!

To choose less toxic, pay attention to the way of spraying, but also pay attention to the time of spraying, to water in time, but also to supplement organic fertilizer in time.

The use of pesticides should be scientific, how to use pesticides safely?

When plant pests and diseases occur, insecticides must be sprayed to eliminate the pests. It should be reminded to use non-polluting and low-toxicity pesticides. Each insecticide has instructions for which pests are suitable for the crop, as well as the dosage and how to mix with water.

We use the medicine according to the instructions, and if we use too much, it can cause harm. Fewer pests are difficult to get rid of. The disease is the same.

However, to grasp the time of occurrence of pests and diseases, it is best to achieve good results from the beginning, and when pests and diseases are rampant, it is too late. When it comes to dispensing and spraying, growers are said to know best because they often deal with pests and diseases in field management, and spraying is essential. However, in the more than a decade that I have served agricultural supplies, most of the people I have come into contact with are "vague" and they lower their doses based on their feelings.

Some people in the agricultural materials store the drug seller has ordered how many milliliters to add to each bucket of water. It changes in his hands and always feels: Does it work?

It's not easy to take the second medicine, don't worry.

I thought about it and increased the dose. Pesticides cannot be used scientifically, which is also an important reason why pesticides are currently highly resistant to pests and diseases. Scientific blending and spraying is the key link to ensure the prevention and control effect.

Improper dispensing and mixing of water can affect the concentration of the solution. Too low a concentration can lead to poor efficacy, while too high a concentration can easily cause damage. Improper spraying can cause similar problems.

There are generally two ways to recommend dosage for pesticide packaging. One is the amount of milliliters or grams per acre, which is more common in field crops; The other is the amount of liquid, which is more common in fruit and vegetable cash crops.

Under normal circumstances, the agricultural supply store will tell you how many acres of land there is or how many buckets there are for a bottle of water, and you can use it according to the instructions. Depending on the mixing ratio of water, for example, 2000-3000 times, this means that one kilogram of pesticide can be mixed with 2000-3000 kilograms of water. Or according to ppm (parts per million), for example, parts per million, that is, the dose of a ton of water to the original drug is 1 gram.

Spraying is generally required to be uniform and meticulous, and the spraying is uniform and thorough. For example, if the medicine we need to prepare is diluted 3000 times, we need to add 60 kg of water, then we first find the number 3000 times from the far left, then 60 kg of water in the upper right corner, and then find the cross number. , you can get the desired dose, i.e. 10 ml or 10 grams.

For the current agricultural development, the emergence of various new technologies has increased the speed of agricultural development a lot, especially in terms of yield, as well as the continuous updating of pesticides, but many farmers themselves do not know how to use pesticides, so they will be curious how to use pesticides safely, efficiently and reasonably? In fact, this depends on the manual, as well as what you plant, if you want to figure out the demand, and then you can release pesticides from drones, the efficiency is definitely the highest, and it is also the most efficient, let's analyze it specifically.

First of all, we must admit one thing, no matter how strong the artificial power is, in terms of efficiency and speed of doing things, machinery is far beyond humans, so when we use pesticides at the beginning, what we need is to understand how many pesticides are needed for what we grow, whether this pesticide is suitable, how it is, after these are clear, you can use drones to release pesticides, which is also a very safe effect, of course, before using pesticides, you can read some instructions and say, you can get a lot of answers, A lot of *** and applicability in it have been explained.

If you really don't know anything, it's best to find an expert to show yourself, generally there will be ** support in the countryside now, these talents are there, apply to the village, and you can quickly help yourself identify the like, don't panic and think that this should be used like this, you must figure it out and start again, this is the key.

Of course, there are many varieties of pesticides now, and the applicability is relatively wide, but the effect of each pesticide is different, if you want to be suitable for yourself, don't look at the most expensive and think that this pesticide is good, this is really maybe, sometimes expensive is not necessarily good, cheap is not necessarily bad, the main thing is to see what you do, how to applicability, this is the key to choosing pesticides, we should pay attention.
