What happens to water-dispersible granules when mixed with water?

When water-dispersible granules are mixed with water, they typically form a suspension. This means that the granules do not completely dissolve in the water, but rather disperse throughout the liquid, creating a mixture where the particles remain suspended. This is an important characteristic of water-dispersible granules, as it allows for effective application in pest management.

In a suspension, the solid particles are finely distributed throughout the liquid, which helps ensure that the active ingredients are evenly spread when applied. This contrasts with completely dissolving, where the particles would become invisible in the solution, and with settling at the bottom, where the substances would no longer be uniformly available for effective application. Additionally, clumping together would indicate a poor dispersion, which is not the nature of water-dispersible granules designed for even mixing and effective delivery of active ingredients. Understanding the behavior of these granules in water is essential for proper pesticide application and achieving desired outcomes in pest control.
