Planting vegetables and pesticides is a big deal, what time is the best time to choose to fight pest

Pesticides should be sprayed at least 14 days apart, otherwise it will cause poisoning and other phenomena, and do not spray pesticides in a large area, otherwise the drug is difficult to clean up on the vegetables.

Spraying pesticides must choose a sunny day, in this day it is best to choose two time periods, the first is about 10,00 in the morning, if it is too early, I am afraid that there is dew on the leaves of crops, and the dew will dilute the pesticides, so it is best to wait until the sun comes out, and then apply agriculture after the dew on the leaves of the crops, and if it is noon, the pesticides not only do not play the role of insecticide, but are not good for crops, the sun is the strongest at noon, the temperature is too high, Spraying pesticides at this time can easily cause the leaves of crops to be poisoned and wilted.

The best time of the day to apply pesticides, many medicine sellers or agricultural technicians must tell you, is before 10 o'clock in the morning and after 4 o'clock in the evening.

That's fine, but the problem is that the dew doesn't go down until seven or eight o'clock in the morning, and it comes up again at six or seven o'clock in the evening. In just a few hours, how can a farmer who has been planting land for ten days or eight days? How long does it take to get a single dose?

How do I determine the best time to apply pesticides? It depends on what spraying tools are used, what kind of medicine is used, and what period the crops are in. The best time to apply the medicine is always a few hours, but it is not enough!

Let's talk about spraying tools first:

1 Plant protection aircraft.

Plant protection aircraft operate efficiently, quickly and with long working hours. In the process of operation, people are safer and more convenient. The airplane flies over the seedlings, people do not stick to the medicine, and the medicine is evenly dispersed on each seedling.

The plant protection machine needs to avoid sun exposure, because the fog droplets it sprays are small, and a large amount of volatilization will be caused by the sun. In this way, we use spraying pumps and sprayers to spray differently, the lowest distance from the seedlings is meters, and people use spraying pumps and sprayers to spray, and the height of the seedlings is less than the meter.

The plant protection machine sprays the pesticide with downward pressure airflow, and the dew on the seedlings will be blown off by the wind and then dropped. Therefore, except for 11 a.m. to p.m., the plant protection machine can be played the rest of the time.

2 Spray pumps and sprayers.

The best time to spray the pump and sprayer is indeed from 7 to 10 a.m. and from 7 p.m. to 7 p.m. During this period, the reason why the medicine is good is not that the rest of the time is not good, but when there is dew, the person will rub off the medicine, resulting in the medicine is not good, and there is no problem in the rest of the place.

Farmers use a lot of medicine and too little water. A little dew drops on the seedlings not only does not reduce the efficacy, but the effect is better than when there is none.

This is what farmers often struggle with, whether it is better to get up early in the morning with dew to play glyphosate, or not to use glyphosate without dew. Actually, both methods work, I've fought both. However, there is dew to hit, and the weeds die faster.

Some farmers say that it is not easy to use after beating, but it is actually a problem of water, and try to use water from the mouth of the pond that has been dried for two days.

Let's talk about the period of the crops:

When the rice is pollinated, the spraying must be completed before 8 a.m. and started after 4 p.m. The rest of the time is sprayed, and the loss of rice is very large, which seriously affects the yield.

Finally, the use of potions:

Spraying insect medicine can be sprayed at other times throughout the day, except for high temperature evaporation and personnel poisoning. Try to buy stomach killer medicine for spraying insects, and you need to pay attention to the entry and exit time of insects for the contact killing type.

Fungicides and herbicides, we avoid high temperatures, avoid rain, and spray all day. Spray them, there are no contraindications. As long as you pay attention to the ratio of liquid medicine, you can't exclude each other.

As long as it is not the flowering and pollination period of crops, throw away the high temperature and sun, and apply pesticides at any time of the day. Farmers are not as complicated as everyone thinks.

A good choice for pesticides, the afternoon of the day is the best, in the afternoon, the weather is more refreshing, and can make our pesticides better absorbed, but also because of the high temperature to destroy the molecular structure of pesticides.

In the summer, it is at 9 a.m. and 4 p.m., and in the winter at 2 to 3 p.m., so that the effect of pesticides is at its best.

I think it's in the morning, because there is more dew in the morning, and it is better to use pesticides.

Many vegetables are covered with pesticides. Rural people will also use pesticides when growing vegetables, and they will only use pesticides less often, and they will not get the danger to their bodies.

Under normal circumstances, pesticides are used, and there are almost no pesticides that are not; No, I am a rural person, I know that you must use pesticides to grow vegetables, and if you don't use pesticides, you won't survive at all, and most of them are eaten by insects.

The dishes eaten by my family usually use less pesticides or no pesticides. The vegetables sold in the market are carefully selected, and if you don't use pesticides, you will have insect eyes. Many people do not choose such vegetables.

Abstract Generally, it is better to play at five or six o'clock in the morning, play in the morning, the medicine will evaporate as soon as the sun comes out, and the insects generally do not eat vegetable leaves when the temperature is high in the morning. In order to protect crops, farmers use as few pesticides as possible. Therefore, they should only use pesticides at the right time, in the right place and in the right amount.

What is the best time to spray pesticides on vegetables?

Hello dear. This question is being answered for you, you need to wait patiently for about 5 minutes, and the answer will be revealed for you immediately, please don't worry!

Generally, it is better to play at five or six o'clock in the morning, and in the morning, the medicine will evaporate as soon as the sun comes out, and the insects generally do not eat vegetable leaves when the temperature is high in the morning. In order to protect crops, farmers use as few pesticides as possible. Therefore, they should only use pesticides at the right time, in the right place and in the right amount.

The use of pesticides is an important means of agricultural production at present, and it has also made great contributions to our country's agricultural production and ensuring a bumper grain harvest. In view of the current agricultural production is still in the scattered stage, the use of pesticides is more chaotic, the use of pesticide technology and use methods need to be improved, the most critical of which is the quality of spraying pesticides, the time of spraying is the most important, the same pesticide is used in different time periods, the effect is very different. When is the best time to spray pesticides, many farmers do not know very well, the author will share this problem with the majority of farmers to help you improve the use of pesticides.

The best time to spray

The best time of day to spray in the summer high temperature season is after the dew has dried in the morning and before 10 o'clock and after 4 o'clock in the afternoon. Because the transpiration of the leaves of the crop is weakened at this time, the respiratory stomata of the leaves are stretched and opened, which is conducive to the absorption of the liquid medicine and the improvement of the use effect of the agent. The cool season of spring and autumn should be sprayed after 9 a.m. and before 2 p.m.

At this time, spraying is conducive to the exertion and penetration of the efficacy, and improves the penetration effect of the agent. At this time, the outdoor temperature is kept at about 15 degrees, which is conducive to the absorption of the liquid.

In the cold season of winter and spring, we must choose to spray when the temperature rises and the climate is warm. At this time, the timing of spraying is not too much, mainly in the spring of the fruit tree garden, the choice of pesticides is mainly some agents with good systemic properties.

The best time to spray different varieties

1. The spraying time of corn herbicide is also different, and the application time of closed herbicide is most suitable for spraying around 5-6 o'clock in the evening on a sunny or cloudy day, because spraying can reduce the volatilization of the liquid at this time, and after a night of penetration and absorption, it can improve the killing effect of weeds and grass buds. If you choose to spray after rain or in dewy weather, the effect will be even better. The spraying time of post-emergence herbicide should also be selected before 10 o'clock in the morning, spraying after 4 o'clock in the afternoon, and the outdoor temperature should be kept at 16 -23 at this time, the temperature at this time is conducive to the killing of weeds, and the speed of weeding is improved.

Personally, I think it is best to use pesticides when the crops are growing, and the time when I feel that the pests are about to grow is the best, and to prevent them in advance, so that the pests will not harm the crops.

It is best to choose after 9 a.m. and 4 p.m. in the day to spray pesticides, and never spray at noon, which will halve the effect and have no effect.

It is best to choose the morning or evening of the day to spray pesticides, so that the pesticides can better exert their effects.

When the weather is fine, around 9 o'clock in the morning and after 4 o'clock in the afternoon, the temperature is suitable, and the pests are out to move, and the sterilization effect is the best.
