Which option is NOT a major classification of pesticides?

• A. Classification by usage
• B. Classification by chemical type
• C. Classification by hazard
• D. Classification by color

Answer: (D)

Pesticide classification is organized to guide safe handling, labeling, and application. The major ways we categorize pesticides are by how they are used (usage), by what they’re made of (chemical type), and by the hazard they pose (toxicity and environmental risk). These classifications help determine when and where a product can be used, what protective equipment is needed, and how it should be stored or disposed of. Color as a criterion would not provide reliable or actionable information, since colors vary widely between products, formulations, and brands and do not reflect composition, mechanism of action, or toxicity. That’s why color is not used as a major classification of pesticides.
