What are the precautions for spraying pesticides in hot weather in summer?

There are two reasons:

First, the temperature is extremely high at noon and it evaporates quickly. It can be said that just after playing, the back is basically dry, which is a serious waste and the effect cannot be achieved.

Second, physical health problems, taking medicine at noon is easy to get heatstroke, causing danger.

2. Selection of spraying time

The first point is, don't take medicine at noon, so when is the best time to take medicine? It is suggested to choose 7-9 o'clock, 16- 19 o'clock, or both.

3. Pay attention to the contact between drugs and skin.

Wear less clothes in summer, and potions are easy to get on the skin. Exposure can cause allergies, poisoning and other symptoms. In addition, take a bath in time after taking the medicine.

4, don't arbitrarily increase the concentration of liquid medicine.

Some friends think that evaporation is fast in summer, so they increase the concentration privately, thinking that evaporation will have little effect on the efficacy. In fact, this idea is wrong, and it is easy to cause drug damage and burn leaves.

5, pay attention to the mixture of pesticides

In agricultural production, due to the unbearable hot weather in summer, some friends will mix herbicides, pesticides and fungicides. This is not desirable and must be cautious. For example, it is not recommended to mix herbicides and pesticides, and organophosphorus pesticides cannot be used for one week before and after the use of nicosulfuron, a corn herbicide.

I hope you pay more attention when you actually meet the above five points. In addition, when spraying medicine in summer, you must draw more water. Here's a good idea. For example, under normal circumstances, 1 mu is 1 bottle of medicine 1 barrel of water, but now you can use 1 bottle of medicine and 2 barrels of water 1 mu.
