The EPA action on chlorpyrifos (Dursban/Lorsban) is primarily an agreement with Dow AgroSciences and other manufacturers to rapidly phaseout Chlorpyrifos products. The following explains which use areas will be affected by this action:

  • Production will be stopped and all home, lawn and garden uses of chlorpyrifos eliminated.
  • Production will be stopped and virtually all termiticide uses will be eliminated. Pre-construction treatment (pre-treats) use rates will be set at one half of one percent (0.05%) - According to the EPA, these two use areas were about half of the total use (total use is about 20 million pounds annually)
  • Agricultural uses will be largely retained, BUT tolerances (allowed residues on food crops) will be significantly reduced on those foods that are noted as being a regular part of the diet of children. - Ag uses are the other 50% of total use. This on about 40 different crops.

The EPA notes that this action will affect (loss and label changes) over 825 products.
