Structural Pest Control Applicator Practice Exam

An _______________ is a chemical added to the pesticide mixture that makes an active ingredient more effective.

1. Inhibitor

2. Adjuvant

3. Solvent

4. Activator

The correct answer is: Adjuvant

An adjuvant is a substance added to a pesticide mixture to enhance the effectiveness of the active ingredient. These compounds can modify the properties of the pesticide, allowing for better adherence to surfaces, improved absorption, or increased compatibility with other chemicals. By facilitating the action of the active ingredient, adjuvants play a crucial role in ensuring that the pesticide performs as intended, helping to improve its efficacy in controlling pests. In the context of pest control, understanding the role of adjuvants is vital, as they can improve the distribution of the pesticide over the target area, reduce volatility, or enhance the penetration of the pesticide into plant tissues. This means that when selecting or applying pesticides, considering the presence of adjuvants can significantly impact the overall effectiveness of the pest control strategy.
