The European Union has adopted integrated pest management (IPM) as a policy as part of the Sustainable Use of Pesticides Directive, in which chemical pesticides are used as a last resort. Bringing IPM into the policy for crop protection has focussed attention on using more selective pesticides and especially biopesticides, but to implement IPM well-trained practitioners are required to provide farmers with the support they need to achieve informed pest management. This chapter examines selective pesticides, the importance of dose selection, timing of chemical pesticide treatments and changes in pesticide application technology. The chapter offers an overview of biopesticides, baculoviruses and their application, and the application of bacterial biopesticides. The chapter also looks at the application of entomopathogenic nematodes, release of predators and parasitoids as a form of pest management and the use of pheromones.
