What type of formulation covers either a liquid or dry pesticide particles with plastic?

Microencapsulates are a type of pesticide formulation that encloses either a liquid or dry pesticide within a plastic coating. This encapsulation process allows for controlled release of the active ingredient, enhancing its efficacy and longevity of action. The plastic coating helps protect the pesticide from environmental factors such as moisture, light, and temperature, which can degrade its effectiveness.

Additionally, microencapsulation can improve the safety profile of the pesticide by minimizing the risk of exposure to non-target organisms and reducing potential human health risks during application. This formulation type also allows for targeted delivery, as the release of the pesticide occurs under specific conditions, such as varying pH levels or environmental factors.

In contrast, stickers are used to enhance the adhesion of a pesticide to a surface but do not encapsulate the active ingredient. Granules are solid particles that contain pesticide but do not involve a plastic coating, and emulsions are mixtures of liquids that do not encompass the defined plastic layers typical of microencapsulates.
