What type of pesticide formulation requires minimal agitation during use?

The emulsifiable concentrate formulation requires minimal agitation during use because it is designed to mix well with water and remain stable without extensive stirring. In an emulsifiable concentrate, the active ingredient is dissolved in a solvent, typically an oil, which allows it to form a stable emulsion when mixed with water. This means that once the emulsion is created, it holds its uniformity and does not separate easily, reducing the need for frequent agitation during application.

In contrast, other formulations like wettable powders and water-soluble packets often require more thorough mixing to ensure that the product is properly suspended or dissolved in the spray solution. Granules, on the other hand, are typically used in a dry form and may not require agitation at all during use but are not designed for dilution like emulsifiable concentrates. Thus, emulsifiable concentrates stand out for their ease of use with minimal agitation, making them practical for many applications.
