When is the best time to spray pesticides in summer? Why should you not spray pesticides at noon in summer? Below, Gengzhongbang Planting Network gives a brief introduction for netizens' reference.When spraying pesticides in summer, whether for grain crops, vegetable crops, cash crops, or fruit trees, etc., the best time is around 8 to 10 a.m. and around 5 p.m.
Because around 9 a.m. in summer, the dew has generally dried and the temperature is not yet too high, and this is exactly the peak time for day-active pests to feed, move about, and mate. Therefore, applying the pesticide at this time will not reduce its effectiveness because the pesticide is washed off or diluted by dew, nor will it affect the pesticide's effectiveness because high temperatures cause the pesticide to break down. On the contrary, applying the pesticide at this time actually increases the chances for pests to feed and come into contact with the pesticide, effectively improving the pesticide's killing power. Around 5 p.m., the sun has already moved to the west, exactly the time of "the sun setting in the western hills and evening falling," when the light gradually weakens and night-active pests begin to become active (feeding, mating, and other activities). Therefore, spraying at this time likewise has a relatively high killing effect.
At the same time, it is not suitable to spray pesticides at noon in summer. Because the temperature is high at this time and the sunlight is strong, some pests fear strong light and hide in shaded places, or even stop moving. In addition, at high temperatures the pesticide breaks down quickly, so its effectiveness is instead reduced. At the same time, when pesticides are applied at noon, the spray liquid generally evaporates quickly, which can easily lead to poisoning of people and livestock.
