Weeds are considered pests in agriculture primarily because they compete with crops for vital resources such as nutrients, water, and light. By thriving alongside crops, weeds can absorb nutrients from the soil that would otherwise be available for the crops, leading to reduced crop yield and quality. This competition can stunt growth and hinder the productivity of agricultural systems. Additionally, some weeds may harbor pests and diseases that could further threaten crop health.
