What is true about an encapsulated pesticide?

An encapsulated pesticide is designed to slowly release its active ingredient over time. This gradual release allows for a sustained effect against pests, reducing the need for frequent applications and potentially minimizing environmental impact. By encapsulating the active ingredient in a protective coating, the pesticide can be formulated to release its contents in a controlled manner, which can lead to more effective pest management.

The other choices do not accurately reflect the characteristics of encapsulated pesticides. Sudden release of active ingredients is contrary to the purpose of encapsulation, which aims for a slow and steady release. Encapsulated pesticides are not in gas form; they typically remain solid or liquid within the capsule. Finally, while emulsifiers may be used in some formulations, the defining feature of encapsulated pesticides is not their mixing with emulsifiers but rather the encapsulation process itself that allows for gradual release.
