A pesticide that controls nematodes is called a

• A. Nematicide
• B. Pesticide
• C. Parasite
• D. Monitoring

Answer: (A)

Think in terms of a name that fits the specific pest being targeted. Nematodes are microscopic worms that attack plant roots, so the substance designed to kill them is called a nematicide. The term combines nematode with -cide, meaning “to kill nematodes.” A general pesticide covers pests more broadly, not just nematodes. A parasite is an organism that lives on or in a host and benefits at its expense, not a chemical used to control pests. Monitoring is the act of checking pest presence, not a control product.
