This document provides an overview of basic crop protection. It defines crop protection as preventing damage to crops from living or non-living organisms. Pests are defined as biotic agents that can damage crops. The importance of crop protection is outlined as reducing hazards and negative effects on crops, which can lower yields, quality, and market value while increasing costs.
