Pyrethrins

Special Designations
  • Biopesticide/Biocontrol
Action/Use:
  • Insecticide
Use: Because of their safety, pyrethrum extracts are used extensively in stock sprays, aerosols, industrial sanitation sprays, and to protect stored food in warehouses. These pyrethrins may be extracted in kerosene, alcohol, acetone, or ethylene dichloride for formulation in dusts and sprays. They are incompatible with lime and ordinary soaps because acids and alkalies speed up the processes of hydrolysis. Control of chewing and sucking insects and spider mites on fruit, vegetables, field crops, ornamentals and glasshouse crops.
