Which pesticide formulation must be mixed with water before use by the applicator?

The formulation that must be mixed with water before use is flowables. Flowable formulations are concentrated pesticide formulations that are designed for dilution with water prior to application. This dilution allows for better distribution of the active ingredient over the target area and can help to reduce the potential for environmental contamination.

Flowables generally have a thick, viscous consistency and need the water to achieve the right concentration and consistency for effective application. When mixed correctly with water, flowables can enhance coverage and effectiveness, ensuring that the pesticide adheres well to the surfaces of plants or structures being targeted.

In contrast, aerosols are ready-to-use products that come in pressurized containers and do not require mixing with water. Granules are solid formulations that can be spread directly on the ground and do not involve mixing with water for application. Dusts also are dry formulations that can be applied without prior dilution, typically drifting into target areas as a fine powder. Each of these formulations has specific functions, preparation methods, and uses, but flowables uniquely require dilution before application.
