In the context of pesticides, what does "D" typically indicate?

1. Dry flowable

2. Liquid

3. Dust

4. Gel

The correct answer is: Dust

In the context of pesticides, "D" typically indicates "Dust." Dust formulations are a type of pesticide that come in a fine powder form, designed to adhere to surfaces and be effective against pests. This method allows for a targeted application, making it ideal for areas where liquid formulations might not be suitable due to concerns about runoff or the ability of the formulation to penetrate crevices. Dusts can remain effective for a longer period compared to some other formulations because they do not dissolve in water and can effectively settle on surfaces where insects are likely to traverse. The understanding of this terminology is crucial for pesticide applicators as it helps them select the appropriate product based on the intended use and environment.
