Which statements describe Fluridone brand names and forms?

• A. Sonar, Avast, WhiteCap; liquid and granular; selective systemic herbicide.
• B. Roundup; only granular; non-selective.
• C. Glyphosate; liquid; broad-spectrum.
• D. Diuron; gas; non-selective.

Answer: (A)

Fluridone is an aquatic herbicide used to control submerged and floating weeds, and it works systemically—meaning the plant takes it up and translocates it to kill it rather than just burning the surface. It’s sold under several brand names, including Sonar, Avast, and WhiteCap, and you’ll find it in both liquid and granular formulations to fit different pond treatments. This combination—these brand names plus liquid and granular forms—matches how fluridone is actually marketed and applied in aquatic settings, and its action is selective (targeting certain aquatic plants) as a systemic herbicide. The other options mix in products that aren’t fluridone (for example, Roundup is glyphosate) or mention forms that don’t align with fluridone labeling, so they don’t describe this chemical accurately.
