Uses2

  • For Dieldrin (USEPA/OPP Pesticide Code: 045001) 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./
  • Broad spectrum insecticide used until 1974; EPA restricted its use to termite control by direct soil injection and non-food seed and plant treatment.
  • Dieldrin was used in tropical countries as a residual spray on the inside walls and ceilings of homes for the control of vectors of diseases, mainly malaria.
  • /Dieldrin/ is used to control locusts and tropical disease vectors, such as Glossina species. ... Industrial uses include timber preservation, termite-proofing of plastic and rubber coverings of electrical and telecommunication cables, of plywood and building boards and as a termite barrier in building construction. /Former use/
  • Control of public health insect pests, termites, locusts, and tropical disease vectors. /Former use/
  • Insecticide /Former use/
  • Use restricted to nonagricultural applications
  • Dieldrin is an insecticide; the primary use in the past was for control of pests in corn and in the citrus industry.
