What should I pay attention to when spraying pesticides in hot weather in July?

In July, the Meteorological Observatory announced a national blue rainstorm warning for 32 days, which made farmers feel a little drumming. Since June, there have been four or five times of heavy precipitation in southern China, and many areas have reached the peak of historical data so far. For example, there were five times of heavy precipitation in Hubei in June, and the rainfall records in many areas got rid of the highest value in a single day after being recorded. While the rainfall is increasing, all parts of the country are experiencing high temperatures that are difficult to meet for many years, and even some extreme areas have high temperatures of about 40 degrees.

If you look around the world, maybe you can find some relief from the high temperature. On June 20, a high temperature of 38 degrees occurred in Jansk, Vilho, Siberia, which died in the Arctic Circle. This temperature is nearly 20 degrees higher than the previous average temperature, which is the highest temperature in the Arctic Circle with historical data. Some fans joked that if it continues for another two years, Siberia will become the largest agricultural production and industrial base in the world.

Farmers who grow crops in the fields must pay attention to clearing ditches and canals immediately after heavy rain, especially to heatstroke prevention and humidification at high temperatures. In the case of high temperature, in addition to the need to protect seedlings and promote growth in agriculture and animal husbandry, there are also some matters needing attention in the application of chemical fertilizers in high temperature natural environment. Because of the high temperature, there are generally some drug injuries, and some drugs are generally used well. Perhaps the actual effect will be scattered in the high temperature natural environment, or even have no effect after use.

Let's master it together. The first thing to explain in detail is that when spraying pesticides, you must avoid the high temperature period of the day. If it rains that day or two hours after spraying pesticides, stop spraying pesticides or spray pesticides again. These are all misunderstandings that let us avoid the harm of high-temperature drugs. Finally, it is suggested that farmers should avoid the afternoon time range when applying chemical fertilizers under high temperature standards, especially from 10 to 4: 00 am.
