The introduction of other synthetic insecticides — organophosphate OP insecticides in the s, carbamates in s and pyrethroids in s and the introduction of herbicides and fungicides in the s—s contributed greatly to pest control and agricultural output. Ideally a pesticide must be lethal to the targeted pests, but not to non-target species, including man.

While opponents of a ban on chlorpyrifos cite the risk of trade disruption, proponents are more concerned about the public health impact, pointing to mounting evidence that chlorpyrifos may impair brain development of children and damage cognitive function among adults.
