After 9:00 p.m., the dew on the leaves of crops has dried up, and it is also the time when sunrise pests are in full swing. At this time, the spraying machine will not affect the control effect due to the dilution of the liquid by dew, but also make the pest directly contact with the pesticide and increase the chance of pest poisoning. After 4:00 p.m., the light is weakened, which is the time when the nocturnal pests are about to move out. When the insecticide is applied to the crops in advance, when the pests come out in the evening and at night to move or eat, they will contact with the poison or die of food poisoning. At the same time, it can avoid the evaporation loss of the liquid and the failure of photolysis.
