Pest Control in Agro-ecosystems: An Ecological Approach

Abstract

This text combines two basically different views on pest control namely the scientific researcher's view on pest control and the pesticide regulator's views on pesticide control aiming at a common and pragmatic ecological approach. A set of practicable ’tools’ are discussed that can be used to monitor and reduce environmental impact on agro-ecosystems where the ultimate goal is to move towards a more environmentally sustainable agriculture. General principles governing farming systems and pest control strategies are illustrated with pesticide use and pesticide risk reduction measures in coffee and rice cultivations. Adaptive pest control based on Integrated Pest Management with a rational use of pesticides as a last resort is suggested to be the most viable way forward.
