What is a Water Dispersible Granule?

  1. A powder that dissolves in alcohol

  2. A dry/solid formulation mixed in water

  3. A liquid that can be sprayed directly

  4. A gel-like formulation

The correct answer is: A dry/solid formulation mixed in water

A Water Dispersible Granule (WDG) is specifically a dry or solid formulation that is designed to be mixed with water for application. When water is added, these granules dissolve and form a suspension that can be sprayed onto target areas. This method of formulation combines the advantages of dry formulations with ease of handling and application, providing effective delivery of the pesticide active ingredients. WDGs are favored in agricultural practices because they minimize dust during handling, reduce the risk of inhalation exposure for applicators, and offer a convenient means to achieve a uniform spray mixture when mixed properly with water. This formulation type is especially useful for pesticides that require dilution before use, allowing for precise control over the concentration and application of the pesticide. Other options describe different formulation types that do not align with the definition of a Water Dispersible Granule. For example, a liquid form wouldn’t require mixing to achieve the application phase, and gel-like formulations serve different purposes and are not designed for water dilution in the way WDGs are.
