What is a common formulation characteristic of microencapsulated pesticides?

Microencapsulated pesticides are designed with a specific formulation characteristic that involves encasing the active ingredients in tiny particles, or capsules. This method allows for controlled release of the pesticide, which can extend its effectiveness and reduce the risk of immediate environmental impact. The encapsulation provides a protective layer around the active substances and often helps in safeguarding them from environmental factors, thereby enhancing stability and prolonging the duration of their effectiveness.

In contrast, instant release of active ingredients, dependence on high moisture levels, and fast degradation in sunlight do not characterize microencapsulated formulations. Instant release is typically associated with other types of formulations that are designed for immediate action. Dependence on high moisture levels can lead to issues with application and effectiveness, and fast degradation in sunlight would negate the purpose of encapsulation, which aims to protect the active ingredients from such degradation. Thus, the correct answer focuses on the fundamental feature of microencapsulation itself.
