The best time to spray pesticides in summer

Posted on

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