What type of dry/solid pesticide formulation consists of uniform particles that are the same weight and shape?

Pellets are a type of dry pesticide formulation characterized by their uniformity in particle size, weight, and shape. This consistency allows for precise application, making them effective for target pest control. The uniform particle structure ensures that when the pellets are distributed, they provide an even spread and predictable performance in the field. This is especially important in agricultural settings where even coverage can lead to more effective pest management.

Granules, while also solid formulations, often vary in size and shape, leading to less uniformity in application. Powders can vary significantly in texture and size, which could affect the way they disperse and settle in the application area. Crystals are typically associated with solid formulations that may not have the same uniformity in size and shape as pellets. Thus, pellets stand out as the most suitable answer for this question due to their specific formulation characteristics that emphasize uniformity.
