What are the precautions for using pesticides in the rainy season?

Spraying pesticides in the rainy season by all meansPay attention to the timing of spraying pesticides and the choice of drugs。There are many organisms in nature, and although society advocates the conservation of species diversity, for people engaged in agricultural production, bugs that eat food can do more harm than good. In order to ensure the healthy growth of grain and a good harvest during the harvest season, the farmer uncle will always spray pesticides regularly.

Even in the rainy season, when pesticides are easily washed away and the utilization is not high, they will seize all the time to spray.

Spraying pesticides after rain is more utilizable. It often rains during the rainy season, and if you want to spray pesticides at this time, you should pay attention to the weather forecast. The weather forecast is now quite developed, and it can be ** whether there will be rain in the next few hours.

So, if you want to spray pesticides, you can pay attention to the weather conditions in the next few hours after the rain. If there is no rain, this is the best time to spray pesticides, as this is when the pesticides can remain on the plants for a long time and will not be washed away by the rain.

Choose systemic pesticides, the effect is better. There are many types of pesticides, and in the rainy season, it is best to choose pesticides with good systemic properties. In this way, pesticides are sprayed.

Within four or five hours, the pesticide will be absorbed into the body by the plant. When the pests eat the plants, they will be poisoned and die. Once pesticides are inhaled into plants, even if it rains, it will not affect the efficacy of the pesticides. Therefore, only by choosing the right pesticides, the insecticidal effect will be better.

Choose fast-acting pesticides。Compared with systemic pesticides, fast-acting pesticides have a faster insecticidal effect. Although fast-acting pesticides are not inhaled by plants and can maintain their insecticidal effect for a long time, they can quickly eliminate pests within one to two hours after spraying.

If there are many pests and are eating the plants, the effect of using fast-acting pesticides is very good.

Increase the concentration of pesticides。The rainy season is watery and the air is humid. When pesticides are sprayed, they are likely to be washed away by rain or diluted by moisture in the air, reducing the effectiveness of pesticides.

Therefore, when preparing pesticides, the concentration of pesticides can be slightly increased, so that they can also play a better role.

The first point should be careful not to use too much, otherwise there will be no effect, the second point should be mastered, the most basic amount should be skillful, and the third point should be mastered where the pesticide should be sprayed.

Pay attention to the systemic property of pesticides, but also pay attention to the harm of pesticides, pay attention to the effect of pesticides, and also pay attention to the right medicine, but also pay attention to the use of pesticides.

It is necessary to choose targeted pesticides, choose pesticides that are not afraid of water, otherwise it will affect the medicinal properties, and also choose safe pesticides, be sure to stay away from fire sources, and be sure to store pesticides well.

Be sure to avoid rainy days, and when using pesticides, you must choose a time when the temperature is more suitable, you can choose at 9:00 10:00 in the morning, and then you must pay attention to the variety of pesticides, and you must pay attention to the concentration and dosage of pesticides.

Rainfall during the rainy season can severely reduce the effectiveness of pesticides.

If the pests and diseases are serious and drugs are urgently needed, attention should be paid to the selection of pesticides, and the selection of internal, fast-acting, rain-resistant pesticides, and microbial pesticides should be used to avoid losing their efficacy due to rainfall. Because inhaled pesticides can be absorbed by crops through their roots, stems, leaves, etc., and work in a short time. Check the weather forecast every day during the rainy season.

Stay on top of rainfall and spray pesticides. When spraying, always be mindful of weather changes and be flexible. In general, the effect of applying pesticides after rain is good. Therefore, the appropriate time period can be selected according to the weather conditions and actual situation to improve the control effect.

After spraying pesticides, the effectiveness of pesticides will be reduced in rainy days. After spraying the plant for 2 to 4 hours to take effect, the pesticide components have not been completely absorbed by the plant, and some remain on the surface of the plant. If it is washed by rain, the pesticide will be washed away.

If it rains 1 day after spraying, the effect has already taken effect, and the rain will not have any effect.

During the rainy season, pay attention to changing the application method of pesticides appropriately. For example, when using systemic pesticides, pests are mixed into fine soil before they occur, and then applied to the soil near the crops, allowing the plants to absorb the pesticide and thus cause the pests to absorb the pests and die, this method is one of the more commonly used methods in the rainy season. At the same time, according to the activity law of pests, the application time should be reasonably selected.

For example, for some nocturnal pests, it should be used at night, while sunrise pests should be used in the morning.

In general, rain immediately after the injection has a great impact on the efficacy, and most of them need to be sprayed. If it rains 1-4 hours after spraying, it depends on the amount of rainfall and the pesticide composition used, generally after spraying, use pesticides with strong internal permeability, quick effect, and rainwater erosion resistance for 2-3 hours, which has almost no effect on the efficacy. There is rain within 4 hours, and the rainfall is small, which basically does not affect the prevention and control effect.

For some microbial active pesticides, such as Beauveria bassiana, Jinggangmycin.

In rainy days, it can give full play to the role of sterilization and stool insecticide, but it should not be used when the rainfall is too large.

Use pesticides in the rainy season, pay attention to waterproofing in time, control temperature, use waterproof tarpaulins, and lights, through these techniques, let the drug absorb quickly.

When applying pesticides in the rainy season, we must pay attention to the fertilization time, and also pay attention to regular spraying, and also pay attention to spraying evenly when spraying. You should also choose some pesticides with relatively safe ingredients, and you can't spray too much at one time. Attention should also be paid to the amount of pesticides used.

Be mindful of how pesticides are used.

It should be to pay attention to the good weather in advance. When spraying pesticides, you must pay attention to the weather that does not rain for 24 or 48 hours, so. We need to read the weather forecast before we continue spraying pesticides.

Pesticides should be applied in the interval between rainfalls, some pesticides with very good absorption, pesticides to prevent erosion, pesticides with good activity, appropriate changes in the concentration of drugs, and some additives.

In the rainy season, we must pay attention to the timing of pesticides, do not spray pesticides on rainy days, otherwise it will affect the effect of pesticides, you should choose to apply pesticides on sunny days, pay attention to the proportion and dosage of pesticides, and pay attention to the amount of watering.

When choosing pesticides in rainy days, you should choose some waterproof pesticides, and you should also concentrate on spraying, and you should also add some nutrient solution to it, but not too much when spraying, you can spread a layer of cover on the surface of crops.

Pay attention to the weather, choose the right time to apply pesticides, choose systemic properties, effectiveness, rain resistance and microbial pesticides in the rainy season, and add adhesives and auxiliary synergists to the liquid medicine.

You can choose some pesticides that are not easy to volatile, and you should also pay attention to the amount of pesticides, and you should also pay attention to the problem of ingredients when using pesticides.

Try not to use pesticides in rainy days, and when using pesticides, you must pay attention to the amount of pesticides, you should also do a good job of personal protection, and also do a good job of drainage, the temperature must be appropriate, and you must avoid rainy days.

It should be that when there is no rain, Qi He waits to spray pesticides, and the pesticide must stay for 24 hours. Only in this way will the Qi clan shoot a high-ranking role.

You can choose some pesticides that work well and spray these pesticides on the roots of the plant, so that you can prevent insect infestations.

Pesticides can be applied on sunny days, so that the effect of the pesticide will not be affected, and the effect of the pesticide will not be affected.

Pesticides can be applied when it is not raining, and it is best not to use pesticides when it rolls a few rainy days. When spraying pesticides, you should also protect yourself, wear a mask, and wash your hands and ** in time after spraying pesticides.

Spray pesticides in the soil, so that you can prevent insect pests and allow plants to grow better, and plants spray pesticides to kill insects.

Crops in the summer high temperature pests and diseases, but summer is also the rainy season, when it rains, those pests and diseases are more rampant, but for farmers and friends when it rains, they can not use pesticides, see in the eyes, anxious in the heart.

In the rainy season, we should pay attention to these two points for pesticide application, know the weather changes in advance, and understand the laws of crops and pests and diseases.

Heavy rain in the rainy season will seriously reduce the effectiveness of pesticides on Cordyceps. And Cordyceps will be overflowing, and at this time, only the correct use of pesticides can protect the growth of crops. Therefore, farmers should not abuse or use pesticides indiscriminately. In general, there are three principles to be mastered:

Three principles Choose the right medicine.

Use the right amount. Use the right time.

The method is as follows: the general time for crops to absorb pesticides is 12 hours, you can pay more attention to the weather, weather forecast, etc., prepare in advance, and take precautions. Of course, weather forecasts may not be accurate.

At this time, you can pay more attention to what insects in your field will come to the crops at what time, and spray pesticides in advance. Pesticides can be sprayed the night before morning activities.

As mentioned earlier, many pesticides take up to 12 hours before they can be fully absorbed. In many cases, because pesticides are slow to act, they will cause damage to crops. At this time, we can use some fast-acting pesticides, such as albutin, deltamethrin, lesben anti-carb, etc., which are fast and effective, and can kill a large area of insects in a short period of time.

Choose rain-resistant pesticides to choose pesticides that are resistant to rain-washout, such as Green Depot, Bordeaux liquid, Jinggangmycin, etc., they can produce a film in about 3 hours, which can prevent the loss of efficacy, if you increase the adhesion and permeability of pesticides, even if it rains, it can also play a better role, you can add some soaphorn liquid, penetrant and so on. Laundry detergent can also be added to increase the adhesion of pesticides. Thus protecting the crops on the efficacy of pesticides.

You can also add human water-soluble adhesives to wettable powder or suspension, such as various animal bone glue, gum, waste honey, etc., some adhesives, after the water volatilizes after the use of medicine, the powder particles can be firmly adhered to the surface of the pesticide object, so as to protect the rainwater from destroying the effect.

Choose targeted pesticides, grasp the time to spray pesticides, do not spray pesticides just after rain, grasp the concentration of pesticides, and look at the weather forecast in advance.

It is necessary to choose the appropriate time period, and pay attention to the way of spraying pesticides, observe the weather forecast, choose appropriate pesticides, and take into account the dilution of rain and moisture.

Use strong systemic pesticides. Such as carbendazim, methyl tobuzin, fenaninin, sukenin, imidacloprid, husper, dimethyltetrachloride and other insecticides, fungicides, herbicides. Generally, after 5 hours of application, more than 80% of the active ingredients of the pesticide have been absorbed into the tissues of the crop.

Be sure to choose the right time, and try not to spray pesticides when the rain is relatively heavy, be sure to pay attention to the concentration of pesticides, and at the same time be sure to avoid such weather, and be sure to do a good job of ventilation, and be sure to do a good job of water and fertilizer management.
