What is the primary purpose of adjuvants in pesticide mixtures?

• A. To increase the toxicity of pesticides
• B. To make pesticides smell better
• C. To increase the color of the spray
• D. To aid or modify the action of a pesticide formulation or the physical characteristics of the mixture

Answer: (D)

Adjuvants are added to pesticide mixtures to improve how the product works and how it behaves in the spray and on targets. They modify physical characteristics like surface tension, wetting, spreading, adhesion, and droplet size, helping the spray cover more leaf surface, stay on the treated area, and reduce drift. They can also improve tank-mix compatibility and sometimes aid penetration of the active ingredient into pests or plant surfaces. In short, the purpose is to aid or modify the action of the pesticide formulation or the physical characteristics of the mixture; they are not meant to increase toxicity, odor, or color.
