What major pest group do herbicides target?

• A. Plant Pathogens
• B. Weeds
• C. Insects
• D. Fungi

Answer: (B)

Herbicides are pesticides used to control weeds, the major plant pests that compete with crops for water, nutrients, and light. They work by disrupting plant-specific processes so the unwanted plants die or stop growing, giving the crop a better chance to thrive. This is why the correct answer is weeds. The other groups—plant pathogens, insects, and fungi—are targeted by different types of pesticides (such as fungicides or insecticides), not by herbicides. In short, herbicides specifically focus on eliminating weeds.
