The best time to spray pesticides in summer
Spraying pesticides in summer, whether for food crops, cash crops or fruit trees, is the best time between 8 am and 10 pm and around 5 pm. At around 9 am, the general dew is dry and the temperature is not too high. It is the most vigorous time for sunrise pests to feed, move, and mate. Therefore, at this time, the medicine will not be washed or diluted by dew to reduce the efficacy. It will not affect the efficacy of the drug due to high temperature. On the contrary, the use of drugs at this time will increase the chances of pests feeding and inducing drugs, effectively improving the lethality of pesticides. At about 5 pm, the sun is already westward. At this time, the light is getting weaker, and the night-time pests start to move (feeding, mating, etc.), so the spray also has a higher killing effect.
In addition, special attention should be paid to spraying pesticides at noon. Because of the high temperature and strong sunlight, some pests are afraid of glare and hide in the backlight, and even stop activities. In addition, the drug decomposes rapidly at high temperature, so the effect is reduced, and at the same time, the drug solution at the noon volatilization is faster, which is likely to cause poisoning of humans and animals.
