What type of pesticide formulation is specifically designed to dissolve in water for application?

The formulation specifically designed to dissolve in water for application is the soluble powder. Soluble powders are formulated to readily dissolve in water, creating a solution that can be easily applied through various methods, such as spraying. This type of formulation allows for precise control over the concentration of the pesticide when mixed with water, ensuring effective application.

Granular formulations are typically dry and may require water to activate or dissolve but are not designed to dissolve completely in water for immediate application. Emulsifiable concentrates involve a mixture of oil and water, requiring agitation to form an emulsion, rather than dissolving. Powders can refer to a broad category that may include multiple types of formulations, but not all powders are soluble. Therefore, soluble powder is the most suitable choice as it is specifically treated to ensure complete dissolution in water for effective pesticide application.
