Which of the following statements is true about inert ingredients in pesticides?

• A. All are non-hazardous
• B. Can be harmful but are not active pesticides
• C. Are actively used in pest control
• D. Require special handling and disposal

Answer: (B)

The statement that inert ingredients in pesticides can be harmful but are not active pesticides is true because inert ingredients, despite their classification, can sometimes pose risks to human health or the environment. While these ingredients do not directly control pests, they serve various roles in the formulation of the pesticide, such as acting as solvents or stabilizers. However, this does not mean that they are without risk; some inert ingredients may be toxic or contribute to environmental harm. Understanding that "inert" does not necessarily indicate safety is crucial for proper handling and use of pesticide products.

The other statements fall short because not all inert ingredients are non-hazardous, some may indeed require special handling or disposal, though not all do, and they are not primarily used for pest control like active ingredients.
