Which dry/solid formulation is specifically mixed in water to reduce inhalation exposure during mixing and loading?

The correct choice is the water dispersible granule (WDG) formulation. This type of formulation is designed to be mixed with water, creating a suspension that can be easily and safely applied. One of the primary benefits of using WDG products is that they minimize inhalation exposure during the mixing and loading process. When WDGs are added to water, they dissolve and disperse, reducing the risk of dust formation that can occur with other dry formulations.

In contrast, granular pesticides and powders are typically more prone to generating dust when handled. This dust can be easily inhaled, posing a risk to the user. Pellets, while larger than powders, can also create some dust when disturbed. Thus, WDG is specifically advantageous for safety during preparation and application due to its ability to be mixed with water, thus limiting the potential for inhaling harmful particulates.
