What is a key disadvantage of microencapsulated pesticides?

Microencapsulated pesticides are designed to release active ingredients slowly over time, which can help control pests more effectively while also reducing the risk of immediate environmental contamination. However, a key disadvantage is that they are almost insoluble in the tank mix, necessitating constant agitation during storage and application to ensure that the pesticide remains evenly distributed. Without continuous agitation, the microencapsulated particles may settle at the bottom or clump together, leading to uneven application and reduced effectiveness.

This characteristic of requiring constant agitation is crucial for maintaining the desired concentration of active ingredients in the mixture, ensuring that the pesticide delivers its intended performance throughout the application process. While they can be highly effective and reduce certain risks to the environment, this requirement for constant agitation can complicate their use, making it essential for applicators to be vigilant during mixing and application.
