Which pesticide formulation features larger particles and a slow-release mechanism, usually resulting in lower active ingredient percentages?

The correct answer is granules. Granules are a type of pesticide formulation that contain larger particles compared to other formulations. This coarser texture allows for a slow-release mechanism, meaning they break down and release their active ingredients more gradually over time. This can result in lower active ingredient concentrations compared to more concentrated forms like liquids or powders, which may be designed for quicker or more immediate impact.

Granules are often used for applications involving soil or lawn treatment, where the slower release can be beneficial for prolonged effectiveness. The use of this formulation helps minimize the risk of runoff and enhances the efficacy in delivering the pesticide to the target area over an extended period, supporting both pest control and environmental safety.
