What type of pesticide formulation is a dry, granular product that disperses in water to form a suspension?

The correct answer identifies Water-Dispersible Granules as the type of pesticide formulation that is dry and granular, capable of dispersing in water to form a suspension. This formulation type is specifically designed to make handling and application easier while ensuring that the active ingredient is effectively delivered when mixed with water.

When Water-Dispersible Granules are added to water, they dissolve and disperse, creating a homogeneous mixture that can be applied uniformly. This characteristic allows for better adherence to surfaces and improved coverage, making them especially effective for various agricultural and pest control applications.

In contrast, the other choices refer to different types of formulations that do not fit this description. For instance, Water-Soluble Concentrates are liquids that dissolve completely in water, whereas Wettable Powders, while similar, require agitation to remain suspended and may not fully dissolve. Finally, Water-Soluble Packets contain pesticides in a soluble form but are typically pre-measured and used without the need for further mixing or dispersing in water. Thus, the nature of their dispersion and application sets Water-Dispersible Granules apart, making them the correct choice for this question.
