What is the definition of a selective pesticide?

• A. A pesticide that affects all organisms
• B. A pesticide that affects a select few or target pests
• C. A pesticide that leaves no residue
• D. A pesticide that is organic only

Answer: (B)

Selective pesticides are designed to harm only specific pests while sparing most non-target organisms. This comes from targeting a pest’s particular biology or behavior, such as a toxin that affects a enzyme or pathway unique to the pest or its group. The goal is effective control of the target pests with minimal impact on beneficial insects, wildlife, and people, which fits well with integrated pest management and reduces environmental consequences. It’s not about residue levels or being organic; those are separate attributes. A pesticide that affects all organisms would be non-selective and broader in impact, which is the opposite of selectivity.
