What term is used for a wettable powder formulation that has been compressed into granule-sized particles?

1. Dry flowable (DF)

2. Ready-to-use (RTU)

3. Emulsifiable concentrate (EC)

4. Concentrate solution

The correct answer is: Dry flowable (DF)

The term used for a wettable powder formulation that has been compressed into granule-sized particles is "dry flowable" (DF). This formulation allows for easier handling, application, and storage, as the granules can be mixed with water to create a suspension for application. Dry flowables typically dissolve well in water, allowing the active ingredients to disperse effectively, similar to how wettable powders function. However, the process of compressing the wettable powder into granules adds a level of convenience, reducing issues like dustiness during handling. This characteristic makes dry flowable formulations popular among pesticide applicators, especially in situations where precise application is needed, or when working in windy conditions. The other options refer to different types of pesticide formulations. Ready-to-use (RTU) indicates a formulation that is pre-mixed and requires no additional dilution. Emulsifiable concentrate (EC) refers to a liquid formulation that can form an emulsion when mixed with water, while concentrate solution pertains to a liquid formulation that contains a higher level of active ingredients that must be diluted prior to application. Each of these formulations has its specific use cases and advantages but does not describe the process of compressing wettable powders into granules.
