Which dry/solid formulation is mixed in water to reduce the risk of inhalation exposure?

The correct answer is water-dispersible granules (WDG) or dry flowables (DF) because these formulations are specifically designed to be mixed with water before application. When mixed, they form a liquid solution or suspension that significantly reduces the likelihood of inhalation exposure for the applicator and bystanders. This is because the concentrated dust found in other dry formulations can become airborne during handling and application, increasing the risk of inhalation.

In contrast, granular formulations, powder formulations, and pellets are generally applied in their solid form. Granular formulations may still generate some dust, leading to inhalation risk if disturbed. Powder formulations have a higher likelihood of creating airborne particles compared to WDG and can easily result in exposure through inhalation. Pellets, while not as dust-prone as powders, still do not provide the same level of safety against inhalation as WDG do when mixed with water. Thus, the use of WDG or dry flowables enhances safety during pest control activities by minimizing dust and potential inhalation risks.
