Function of Pyrethrins：
- Pyrethrins has broad-spectrum, which can control many kinds of pests and reduce the kinds and frequency of medication.
- Pyrethroid is highly efficient and low toxicity, high toxicity to pests, but relatively low toxicity to mammals.
- Pyrethroids have significant poisoning effects and are suitable for rapid control of pest outbreaks.
- Most pyrethrins can be decomposed by photolysis and microbial degradation in the natural environment, so the residue risk is low.
Application of Pyrethrins：
- Used in agriculture to control leaf pests, underground pests, prevent seedling pests, etc.
- Used in mosquito coils, electric mosquito liquid, aerosol, etc.
- Used in hospitals, hotels with lagging spray, long-lasting mosquito and fly extermination.
- Used in livestock breeding for veterinary insecticides to prevent and control livestock body surface parasites.
- Used in industry and storage for insect prevention and preservation, such as wood preservation, grain storage, etc.
