Synthetically prepared analogue, Pyrethroids had tremendous effects on plant foliage and fruits. Human consumption of pyrethroid treated plants was significantly responsible for number of diseases. Occupational exposure to pyrethroids by the human, poses inhalation exposure, dermal and oral exposure or the combination of these various routes.
