Forcing toxic chemicals out of the marketplace can provide a powerful incentive for developing Green Chemistry based alternatives. A market opening makes these solutions commercially viable.
Several new biopesticide technologies have come to market as a result of an older pesticide being banned. Without the bans, the research funding for alternatives and the market space for new products would not have been allocated. For example, the severe restriction of Azinphos-methyl and the ban on methyl parathion made it essential to develop safer alternatives for controlling the Codling Moth (read a case study).
