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

The correct answer is pellet. Pellets are a specific type of pesticide formulation that is characterized by having uniform-sized particles that are consistent in weight and shape. This uniformity in physical characteristics allows for more precise application and distribution when the pesticide is applied, making it easier to achieve the desired efficacy in pest control.

The uniform shape and weight of pellets also facilitate their ability to remain on target surfaces, enhancing their effectiveness compared to other formulations. This characteristic can be particularly useful in agricultural applications where even coverage is crucial for achieving pest management goals.

In contrast, granules can vary in size and shape, which may lead to less uniformity in application. Dust formulations tend to be lighter and can drift more easily, which may result in uneven distribution. Wettable powder, while effective, is designed to be mixed with water to create a sprayable solution and does not maintain the same solid characteristics as pellets. Thus, pellets stand out as the formulation with consistent particle characteristics.
