Which organization defines four categories of insecticide use including non-crop?

• A. EPA
• B. World Health Organization
• C. Xerces Society
• D. Food and Agriculture Organization

Answer: (D)

The organization that defines four categories of insecticide use, including non-crop, is the FAO. International guidelines from the Food and Agriculture Organization provide a framework for pesticide use that covers both crop and non-crop settings, ensuring consistent risk management, labeling, and regulatory approaches across diverse environments such as agriculture, urban/forestry contexts, and stored products. This global standardization helps countries align their registration and application practices with widely accepted categories, which is why FAO is the best fit. The EPA focuses on U.S. regulatory actions rather than an international four-category framework; the World Health Organization emphasizes hazard classifications rather than use categories; the Xerces Society is a conservation organization without a formal global categorization system for insecticide use.
