Ennemis des cultures

This chapter outlines the strategic framework for modern crop protection, shifting from a "kill-all" approach to a systems-based management of the agro-ecosystem. It details the hierarchy of interventions, prevention (prophylaxis), monitoring, and therapy, and explains key principles such as Economic Injury Levels (EIL), resistance management, and the integration of genetic, cultural, biological, and chemical methods to ensure sustainable and economically viable production.
