Best time to spray pesticides in summer

In order to maximize the effectiveness of the drug, it is important to have the best spray time. Practice has proved that, whether it is food, vegetables or cash crops so before 10 o'clock in the morning, around 17 o'clock is the best time. This is because:

Around 9 am, general dew has dried, the temperature is not too high, it is sunrise pests feeding, activity, mating the most productive time, so this time the drug, the drug will not be diluted or flushed dew and lowering drugs It will not cause decomposition of the drug due to high temperature, which will affect the efficacy. On the contrary, the use of drugs at this time will increase the chances of pests feeding and taking medicine, effectively improving the lethality of pesticides. At about 5 o'clock in the afternoon , the sun is already westward. It is the time when the sunset is in the evening, the light intensity is relatively weak, and the night-time pests are active (feeding, mating, etc.), so the spray is just right at it. Before the damage, there is also a higher insecticide rate.
