Chemical control refers to which practice?

• A. Use of pesticides or herbicides to manage an unwanted organism
• B. Mechanical removal of pests
• C. Biological predators
• D. Cultural practices only

Answer: (B)

Chemical control means using chemical substances, such as pesticides or herbicides, to manage an unwanted organism. This approach relies on chemical agents to kill, stop growth, or suppress pests, and it is one of the main strategies in pest management. It differs from mechanical removal, which is physical removal of pests; from biological control, which uses natural enemies like predators or pathogens; and from cultural practices, which involve altering the environment or practices (such as sanitation, crop rotation, or timing) to reduce pest problems. Chemical control can provide rapid, broad suppression, but it should be used responsibly—following label directions, considering resistance management, and protecting non-target organisms and the environment.
