Herbicides are defined as which type of chemicals?

• A. Compounds that kill animals
• B. Compounds that promote growth
• C. Phytotoxic chemicals that are toxic to plants
• D. Chemical fertilizers

Answer: (C)

Herbicides are chemicals that are phytotoxic, meaning they are toxic to plants. They’re used to control or kill weeds by interfering with plant growth, metabolism, or photosynthesis. This definition distinguishes them from substances that kill animals (pesticides targeting animals), from compounds that promote growth (growth promoters), and from chemical fertilizers (which supply nutrients rather than injure plants).
