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

1. Granule

2. Wetting agent

3. Powder

4. Pellet

The correct answer is: Pellet

The choice of pellet as the correct answer is based on a key characteristic of pellet formulations in the context of pesticide applications. Pellets are formulated to have uniform particles that are consistent in both weight and shape, which is crucial for ensuring even distribution and application. This uniformity helps in achieving accurate dosages and effective pest control, as the consistent size and weight allow for predictable behavior when the pellets are distributed. In contrast, granules can vary in size and weight, though they also have a distinct form designed for efficient application. Powders, while also dry formulations, do not possess the same physical characteristics as pellets in terms of uniformity and weight distribution. Wetting agents do not fall under the category of solid pesticides as they are surfactants used to enhance the spreading and adhesion of pesticide solutions but do not represent a solid formulation type. Thus, the uniformity in weight and shape specifically defines why pellets are categorized distinctly from these other formulations.
