Interventions to control pests, diseases and weeds must be based on adequate monitoring methods and tools to determine whether and when to apply direct control measures.

Robust and scientifically sound warning, forecasting and early detection/diagnosis systems (decision support systems) as well as sound threshold values are essential components for decision making.

The official forecasts of pest and/or disease risks, or officially established threshold levels defined for the region must be taken into account before treatments.
