What are examples of adjuvants used in pesticides?

Insect growth regulators
Color enhancers
Plant invigorators
Surfactants, stickers, and buffers

The correct answer is: Surfactants, stickers, and buffers

Pesticides are chemicals used to control pests and diseases in plants, animals, or humans. Adjuvants are substances that are added to pesticides to improve their effectiveness. In this question, three of the choices, insect growth regulators, color enhancers, and plant invigorators, are not adjuvants but are instead types of pesticides. Only option D, which includes surfactants, stickers, and buffers, correctly identifies examples of adjuvants used in pesticides. Surfactants are added to pesticides to reduce surface tension and improve spreading and penetration. Stickers are added to increase adhesion of the pesticide to the plant surface, and buffers are added to improve the compatibility and stability of the pesticide with other chemicals. Therefore, D is the most appropriate answer as it provides examples of adjuvants commonly used in pesticides.
