What is the name of the pesticide formulation that uses clay or ground-up shells as a carrier?

The formulation that uses clay or ground-up shells as a carrier is classified as granulars. This type of pesticide formulation consists of solid particles that can be uniform in size and can flow freely. Granulars are commonly used because they provide a slow-release mechanism, allowing for sustained effectiveness over time without the need for frequent reapplication. The clay or shell materials serve as carriers that help in dispersing the active ingredients evenly and ensure proper adherence to the target area, whether it be on soil or plant surfaces.

Granular formulations are particularly effective for certain applications, such as controlling pests in the soil or providing nutrients in addition to pest control. The coarse texture and weight of granulars contribute to their ability to stay in place and reduce drift, making them advantageous in various pest management strategies. In comparison, liquids involve a different base and application method, emulsions are typically mixtures of oil and water, and aerosols are pressurized liquids dispensed in a fine mist, each serving distinct purposes in pest control.
