Which statement about measuring most dusts, powders, and dry formulations is TRUE?

• A. They are typically measured by weight.
• B. They are never measured; estimated amounts are acceptable.
• C. They should be measured with metal measuring utensils.
• D. They are typically measured by volume.

Answer: (D)

Measuring dry pesticide formulations by volume is the practical norm in many mixing and application scenarios. Labels and field instructions for powders and dry formulations are commonly written in volume units (cups, scoops, pints) because these tools are quick, readily available, and easy to use in the field without a scale. Volume measurements let applicators prepare mixtures efficiently and consistently, which is why this method is considered the standard for most dusts and dry powders. While weighing can be more precise and is used when tight accuracy matters or for small quantities, it isn’t the typical approach for everyday practice with these materials. The emphasis on volume reflects real-world workflow and labeling conventions, making volume measurement the best choice in this context.
