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 9:00 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 lowered because the medicine is rinsed or diluted by dew. It does 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 taking medicine, effectively improving the lethality of pesticides. At about 5 o'clock in the afternoon, the sun is already westward. At this time, the light is getting weaker, and the night-time pests are active (feeding, mating, etc.), so spraying at this time also has a higher killing effect.
Galvanized Steel Coil immerse thin steel plate in the molten zinc groove, so that its surface adheres to a thin sheet of zinc. At present, galvanized steel coil is mainly made of continuous galvanizing process, that is, the rolled steel plate is continuously dipped into galvanized steel plate in the molten zinc plating bath, and the galvanized steel sheet is alloyed. The steel plate is also made by hot dipping, but immediately after the trough, it is heated to about 500 ℃to make the alloy film of zinc and iron. The galvanized steel coil has a good tightness and weldability of the coating.

In addition, special attention should be paid to spraying pesticides at noon. Therefore, the temperature is high, the sun is strong, and some pests are afraid of glare and hide in the backlight, or even stop the activity. In addition, the drug decomposes rapidly at high temperatures, so the efficacy is reduced. At the same time, the general drug solution is evaporated at noon, which is easy to cause poisoning of humans and animals.
