Low pesticide rates may hasten the evolution of resistance by increasing mutation frequencies

J Gressel - Pest management science, 2011 - Wiley Online Library
At very low pesticide rates, a certain low proportion of pests may receive a sublethal dose,
are highly stressed by the pesticide and yet survive. Stress is a general enhancer of …
