Which type of formulation is typically used when water solubility is required?

The formulation that is typically used when water solubility is required is wettable powders. Wettable powders are solid formulations that contain active ingredients in a powdered form, along with various additives that help them dissolve in water to create a suspension. When wettable powders are mixed with water, they disperse effectively, allowing the active ingredients to be applied uniformly to the target area.

This property of wettable powders makes them particularly useful in agricultural practices where achieving a thorough coverage and consistent distribution of the herbicide is crucial for effectiveness. They are often employed in situations requiring targeted applications in liquid form, making them compatible with a variety of spray equipment.

Other formulations like flowables are also designed to be mixed with water and are suitable for some applications, but they typically contain a liquid component as part of their makeup. Baits are generally used for specific types of pests and do not require water solubility, while dusts are non-water-soluble and are used for applications that do not involve dissolving the formulation in water.
