What type of pesticide formulation consists of liquid dispersed as droplets in another liquid and may require agitation?

An emulsion is a type of pesticide formulation where one liquid is finely dispersed in another liquid, often creating a milky appearance. This formulation typically requires agitation to maintain the stability of the emulsion and ensure that the active ingredients remain evenly distributed throughout the mixture.

In an emulsion, the two liquids that are mixed may not naturally blend, so consistent mixing is necessary to prevent separation, which can occur over time. This characteristic is essential for effective application because it ensures that the correct dosage of pesticide is delivered uniformly when the mixture is used. The requirement for agitation is a key aspect of emulsions; if not properly mixed, the effectiveness of the application could be compromised.

Other types of formulations such as granules consist of solid particles and do not require agitation; suspensions can also separate but are distinct in that they involve solid particles suspended in a liquid, rather than one liquid dispersed in another. Solutions are clear mixtures where a solute is completely dissolved in a solvent and do not require the same level of mixing as emulsions do, since they remain stable without agitation.
