Which formulation type is known for creating thick mixes and requiring an emulsifier?

Flowable formulations, often referred to as F or AF types, are specifically designed to create thick mixes and usually require an emulsifier to maintain stability and homogeneity. These formulations consist of finely divided solids suspended in a liquid carrier, which allows for effective application of herbicides that may not dissolve easily in water.

The use of an emulsifier in flowable formulations is crucial because it helps to disperse the active ingredient uniformly in the carrier, preventing separation and settling that could occur if the mix were left unattended. This characteristic makes flowables particularly advantageous for dealing with certain types of herbicides that need to remain suspended during mixing and application to ensure consistent coverage and effectiveness.

In contrast, other formulation types like aerosols, RTU (Ready-To-Use) low concentrate solutions, and ultra-low volume products are designed with different characteristics and applications in mind, which do not typically involve the creation of thick mixes or the requirement of an emulsifier.
