How long does it rain after spraying?

For us farmers, it is inevitable to deal with weeds in the process of planting vegetables, grain and fruits. Moreover, in the process of planting crops, there will always be a phenomenon that the growth rate of crops can never catch up with the growth rate of weeds.

Therefore, in the process of crop growth, weeds must be removed to make crops grow smoothly. If you use manual weeding, the efficiency is too low. Therefore, weeding with drugs often can greatly improve the weeding efficiency.

After spraying, it will take some time for the efficacy to play; Generally speaking, it takes 3-5 hours for the drug to take effect after injection. This waiting time is usually related to weather conditions.

First, the weather is fine and the temperature is high. When we kill herbs, we always watch the weather change; If it is the weather forecast and rainy weather, I don't think anyone will take medicine. It is only on sunny days that it is possible to take medicine.

If it is sunny, the temperature is high; After spraying herbs, it only takes 3 hours at the shortest, and we are no longer afraid of weather changes and rain.

Second, when it is cloudy and the temperature is not high, although the effect of drugs will be slower, it will be very comfortable to do the corresponding weeding work.

In such weather conditions, it may take 5-7 hours for spraying herbs to take effect.

Therefore, spraying herbs in this weather should try to avoid the situation in the morning and evening. Because there will be dew sooner or later, the existence of dew will also seriously affect the efficacy.

Moreover, spraying herbs in hot weather is not only effective, but also pays attention to your personal safety. Working in hot weather is very likely to lead to heatstroke and drug poisoning.
