Biocides are defined as what?

Biocides are defined as what?

• A. A broad-spectrum poison that kills a wide range of organisms
• B. A selective herbicide for weeds
• C. A nutrient supplement for soil
• D. A bait to target pests

Answer: (A)

Biocides are substances that destroy, deter, or control harmful living organisms. The best-fit description is a broad-spectrum poison that kills a wide range of organisms. This captures the idea that biocides aren’t limited to one type of target; they’re broad in scope, affecting many kinds of organisms. The other options describe different things—herbicides target plants, nutrients don’t kill, and baits are delivery methods rather than the defining action of the substance itself.
