What type of pesticide formulation involves active ingredients dissolving in petroleum solvents?

Emulsifiable concentrates are pesticide formulations where the active ingredients are dissolved in petroleum solvents, making them effective in application. This type of formulation is designed to mix with water to form an emulsion, which enhances the distribution of the active ingredient when applied to crops or pests.

The use of petroleum solvents in emulsifiable concentrates allows for a greater solubility of certain active ingredients, which may not mix well with water alone. When mixed with water, the formulation forms a stable emulsion, facilitating the effective delivery of the pesticide to the target area.

Other types of formulations, such as granular formulations, do not contain dissolved active ingredients but rather present them in a solid form. Wettable powders consist of solid active ingredients mixed with an inert carrier, requiring thorough mixing into water to create a suspension. Soluble powders dissolve completely in water but do not rely on petroleum solvents for their formulation. Each of these alternatives has distinct characteristics and is suited for different application needs, distinct from the properties of emulsifiable concentrates.
