The insecticide market has long been dominated, more than 80%, by organophosphates, carbamates, and synthetic pyrethroids. The consequence is the development of resistant strains to these three insecticide classes. For effective crop protection, development of a new insecticide class with a new mode of action has been urgently required Future insecticides, as seen from the retreat of chlorinated hydrocarbons from the primary seat, are required to have not only high insecticidal potentials, but also low toxicity to vertebrates and no damage to the environment. Furthermore, these agents are expected to have sufficient stability under weathering conditions to reduce application times for the decreasing farmer population. The recently developed chloronicotinyl insecticides meet these requirements for the modem pesticides. This article describes how this new insecticide class was found.
