What is the primary characteristic of Water-dispersible Granules (WDG) in pesticide formulation?

Water-dispersible Granules (WDG) are designed specifically for mixing with water to create a sprayable solution. The primary characteristic of WDG formulations is that they come in the form of small granules which are easy to measure and handle. When mixed with water, they disperse to form a concentrated solution that can be applied effectively for pest control. This makes them particularly advantageous for applicators since they provide a precise dosing capability and are safer to handle than liquids, while still delivering the active ingredients needed for effective performance.

The other options present characteristics that do not align with the nature of WDG. For instance, while some formulations may be liquids or powders, WDG are granules that require mixing, thus emphasizing the importance of understanding how to prepare them for application accurately.
