What are the precautions for spraying pesticides at high temperature in summer? Small farmer Wang thinks that spraying pesticides in summer should pay attention to the following points: first, pay attention to timeliness and choose pesticides with quick efficacy; Second, pay attention to safety. High temperature weather is a test for people and pesticides, so we must pay attention to safety. The third is to ensure that the efficacy has enough time to play, and always pay attention to the weather changes; Fourth, on the premise of ensuring the efficacy, reduce the concentration as much as possible to ensure the safety of crops.

The use of pesticides in agriculture is large and frequent, especially in summer, plants grow rapidly, and the probability of diseases and insect pests is increasing. Frequent spraying of pesticides in summer must pay attention to safety.

When spraying pesticides in summer, I always choose pesticides that can exert their efficacy quickly. I try to avoid using those that take a long time and have a slow effect.

How many kinds of pesticides are there? I also believe that even if you have been a farmer all your life, you can't count it. A variety of pesticides deal with a variety of pests and diseases, and sometimes there may be several or more pesticides to choose from to deal with a pest or disease.

In the case of ensuring the quality of pesticides, I usually choose pesticides with quick efficacy in summer.

This can improve the efficacy of pesticides, and at the same time, the weather is changeable in summer, and the efficacy cannot be exerted in time. It may be that after a thunderstorm, the efficacy is completely gone, and it is necessary to spray it again, wasting manpower and material resources.

When spraying pesticides in summer, we must pay attention to safety, especially the safety of personnel.

Summer is hot at first, so don't spray pesticides at noon. The sun is very hot at noon, which is a great test for personnel work.

It is easy to get heatstroke or pesticide poisoning. In hot weather, outdoor work should be avoided as much as possible, but farmers can't avoid it, so we must take good protection for such a long time.

When spraying pesticides, you must wear hats, masks and gloves to minimize skin contact. At the same time, the weather is hot, and there may be uncertainty about pesticides. Excessive inhalation of pesticide spray may lead to poisoning. When spraying, try to stay away from the fog and inhale as little as possible to avoid poisoning.

Summer is not only high temperature, but also changeable weather. Before spraying pesticides, we must pay attention to the weather changes to avoid sudden rainfall and make pesticides ineffective.

When choosing quick-acting pesticides, we must choose the time of spraying pesticides, mainly paying attention to weather changes.

The weather forecast must be watched, although it is not allowed most of the time. Before spraying pesticides, I mainly look at the clouds in the sky. If I'm sure it won't rain in 3-4 hours, I'll spray pesticides.

The changeable weather in summer is the biggest enemy of spraying pesticides. Sometimes, just a few minutes after taking the medicine, a rainstorm will make us futile.

Therefore, before spraying pesticides, it is necessary to determine the time of efficacy and the time of rain. Don't rain just after spraying, and it will dry up in vain.

When spraying pesticides in summer, try to dilute the concentration of pesticides under the premise of ensuring the efficacy. The weather is hot, and there are uncertainties in pesticides and crops. Dilution concentration can reduce risks and ensure personnel safety.

High temperature is not only a test for people, but also a test for pesticides and crops. Even the commonly used pesticides may have uncertain factors under the action of high temperature, so try to dilute the pesticide concentration under the premise of ensuring the efficacy.

At the same time, the absorption and growth of crops are accelerated at high temperature. At this time, the concentration of pesticides should be reduced to avoid the occurrence of Chinese medicine harm in aquaculture.

Similarly, under the action of high temperature, pesticides may play a role quickly, and people's skin will be absorbed quickly after contact. Reducing the concentration of pesticides can also ensure the safety of operators to a certain extent.

High temperature in summer, farming will enter a rapid growth period, and summer is also a concentrated stage of pests and diseases, which determines that we should spray pesticides frequently. Spraying pesticides in summer actually needs two main effects to ensure the safety of construction workers, among which ensuring the safety of workers is the most important.
