Which type of pesticide formulation has an AI concentration of 25-80% and is mixed with water?

The correct choice is soluble powders, which are a type of pesticide formulation that contains an active ingredient (AI) concentration typically between 25% to 80%. These powders are designed to dissolve in water easily, allowing for effective application as a spray solution. This high concentration of active ingredients makes them particularly potent, which means they can be effective at lower volumes in applications.

The formulation's ability to mix well with water is important for ensuring that the active ingredients can be evenly distributed and effectively delivered to the target pests. Soluble powders are favored in certain situations due to their ease of use and the flexibility they give in adjusting application rates based on specific pest management needs.

In contrast, other formulations such as granules contain a lower concentration of active ingredients and are not mixed with water but instead are spread on the surface. Wettable powders also dissolve in water but typically have a lower AI concentration. Flowables are liquid formulations that contain suspended solid particles and generally offer a different set of application characteristics and use cases. Knowing the unique properties of these different types of formulations allows pesticide applicators to choose the right type for their specific pest management situations.
