North Carolina Pesticide Application Practice Test

What is the definition of microencapsulated material in pesticide application?

1. A type of pesticide that includes a liquid or dry formulation coated in plastic

2. A biodegradable pesticide that can be completely absorbed by plants

3. A method to dilute pesticides with water for easier application

4. A type of pesticide that requires an aerosol can for application

The correct answer is: A type of pesticide that includes a liquid or dry formulation coated in plastic

The definition of microencapsulated material in pesticide application refers to a type of pesticide formulation that involves encapsulating the active ingredients within a protective coating, typically made of plastic. This coating serves several purposes: it protects the active ingredient from environmental degradation, controls the release of the pesticide over time (allowing for a sustained effect), and minimizes the risk of off-target movement. The encapsulation can enhance safety, improve efficacy, and extend the shelf life of the pesticide. In contrast, the other options describe different concepts not associated with microencapsulation. Biodegradable pesticides pertain to a different category focused on environmental impact rather than the form of application. The method of diluting pesticides specifically addresses the preparation for application rather than the formulation itself. Meanwhile, requiring an aerosol can for application refers to a type of delivery system, which is separate from the encapsulation technique. Understanding these distinctions is critical for effective pesticide management and application strategies in agricultural practice.
