Which pesticide formulation can be mixed with water for use in a sprayer tank?

Emulsifiable concentrate is the correct choice because this formulation is designed to mix readily with water, creating an emulsion that can be used effectively in a spray application. Emulsifiable concentrates contain active ingredients dissolved in a petroleum or other solvent that will disperse in water when agitated, allowing for uniform application and good coverage of surfaces.

Granular formulations, on the other hand, are typically solid pellets or granules that require spreading rather than spraying, as they do not dissolve in water. Capsule suspensions consist of active ingredients encapsulated in a coating material, which alters their release properties but does not allow for mixing into liquid water in the way emulsifiable concentrates do. Powders can often be mixed with water, but they may not provide the same stability or mixing characteristics as an emulsifiable concentrate.

Thus, emulsifiable concentrate stands out as the formulation specifically designed for integration with water in a sprayer tank.
