The best time to spray pesticides in summer

Spraying pesticides in summer is best for food crops, cash crops, fruit trees, etc., from 8 am to 10 am and 5 pm. Around 9 am, the general dew is dry and the temperature is not too high. It is the most vigorous time for the sunrise pests to feed, eat, and mate. Therefore, medication is not used to reduce the drug because it is washed or diluted with dew. Effectiveness will not affect the efficacy due to the decomposition of chemicals due to high temperatures. On the contrary, the use of drugs at the time will increase the chances of pests feeding and touching drugs, effectively increasing the lethality of pesticides. At about 5 o'clock in the afternoon, the sun was already on the west side. At this time, the light became faint and the nocturnal insects became active (feeding, mating, etc.). Therefore, spraying at this time also had a higher killing effect.
In addition, special attention should be paid to spraying pesticides at noon. Therefore, when the temperature is high and the sunlight is strong, some pests are afraid of the light and hide in the backlight, and even stop their activities. Combined with rapid drug decomposition at high temperatures, the efficacy is reduced. At the same time, the general drug solution at the noon volatilizes quickly and easily leads to poisoning of humans and animals.
