What characterizes a suspension formulation?

A suspension formulation is characterized by the presence of solid particles that are dispersed throughout a liquid medium but are not completely dissolved in it. This causes the formulation to appear cloudy rather than transparent. Because the solid particles can settle out over time, regular agitation is necessary to ensure that the active ingredients remain evenly distributed throughout the liquid. This is crucial for the effectiveness of the herbicide when applied, as uneven distribution can lead to inconsistent results in weed control.

The requirement for agitation distinguishes suspensions from other types of formulations, such as emulsions or soluble liquids. Overall, understanding the properties of suspension formulations is vital for applicators to ensure proper handling and application, maximizing the herbicide's effectiveness.
