Uses3

  • Control of rats and mice. Bait shyness does not occur after feeding. Renders cereal bait resistant to insect infestation and fungal infection. **PEER REVIEWED**
  • For pindone (USEPA/OPP Pesticide Code: 067703) there are 0 labels match. /SRP: Not registered for current use in the U.S., but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses./ **PEER REVIEWED**
  • Pharmaceutical intermediate; insecticide; rodenticide. **PEER REVIEWED**
  • Was originally suggested as a substitute for the greater part of the pyrethrins in pyrethrum sprays ... it is used as an anticoagulant rodenticide in baits containing 250 mg/kg **PEER REVIEWED**
