Which dry/solid formulation is mixed in water and reduces the risk of inhalation exposure during mixing and loading?

The correct choice is water-dispersible granule (WDG) or dry flowable (DF) because this formulation type is specifically designed to be mixed with water, forming a suspension that minimizes dust generation during the mixing and loading process. This characteristic significantly reduces the risk of inhalation exposure to pesticide particles, which can be a concern with other formulation types that generate more dust.

Water-dispersible granules dissolve in water, allowing for a more manageable application without the airborne particles that can occur with dry powders. This formulation is particularly advantageous as it combines the benefits of solid formulations while addressing the safety concerns related to inhalation exposure.

While other formulations like granular formulations might not produce as much dust, they may not be mixed with water for application or may not reduce inhalation exposure as effectively. Microencapsulated formulations can also mitigate exposure but do so through a different mechanism and may not be as straightforward to combine with water. Wettable powders, although effective when mixed with water, often produce more airborne dust during handling compared to WDGs or dry flowables. Thus, WDGs and dry flowables are specifically engineered to minimize the inhalation risk during the application process.
