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

The correct choice is pellet, as this type of dry pesticide formulation consists of uniformly shaped and sized particles. Pellets are specifically designed to ensure even distribution and consistent delivery of the active ingredient. This uniformity helps in achieving a balanced application, making them effective for targeted pesticide applications.

In contrast, other formulations do not possess this level of uniformity. Baits typically contain active ingredients combined with a food carrier but do not guarantee uniform particle shape or size. Granules, while they may be larger than pellets, can vary in size and shape and are often used for slower release of pesticides into the environment. Dusts consist of very fine particles and do not maintain the same weight and shape consistency as pellets. Thus, when it comes to precise application and uniformity in dry pesticide formulations, pellets are the clear choice.
