In turf spray operations, an adjuvant primarily serves to improve what?

• A. To increase the toxicity of the active ingredient.
• B. To act as the pesticide itself.
• C. To reduce spray drift by itself.
• D. To improve coverage, spread, or dispersion on leaf surfaces.

Answer: (A)

Adjuvants are added to pesticides to enhance how the spray interacts with leaf surfaces. They aren’t pesticides themselves and don’t increase the active ingredient’s inherent toxicity. Their main role is to improve wetting, spreading, and deposition on the leaf so the pesticide covers more area and contacts more of the plant’s surface. While some adjuvants can help with drift control or sticking to leaves, the central purpose in turf spraying is to achieve better coverage, spread, or dispersion on leaf surfaces.
