WHEN THE PESTICIDES RUN OUT

Abstract

So scientists are pursuing alternatives that may reduce or replace synthetic pesticides. They are particularly interested in biological solutions, including microbes, genetic engineering and biomolecules. Even major chemical companies see enough promise to invest in the work. That doesn't spell the end of synthetic pesticides, but it could help to slow the spread of resistance. Some approaches might also help farmers to reduce costs, protect workers and please a public that is increasingly wary of synthetic chemicals.
