摘要

This chapter presents the story of a long and as yet unsuccessful struggle toudfind suitable fungal and/or insect biocontrol agents for ragweed, a plant that became audwidespread allergenic weed in Eastern Europe. This effort illustrates why biocontrol initiatives,udalthough desirable, sometimes cannot be implemented into practical control strategies,udin spite of the fact that they might represent a realistic solution to problems affecting humanudhealth, the environment and agricultural productivity.
