White Cap

The active ingredient in White Cap (fluridone) has been around for many years now and has proven itself to be invaluable in the control of submerged weeds and duckweed in ponds. The original brand Sonar™ contains the same active ingredient. White Cap is a lower cost alternative. We also carry Sonar offering our customers the choices they deserve.

Fluridone the active ingredient in White Cap remains our # 1 Pond recommendation for the control of submerged weeds and floating duckweed. Our commercial service could not be without it. Systemic action can control plants all season. White Cap is a concentrated product; a few ounces for a small pond can keep the weeds out all summer. No fishing or swimming restrictions. Rates below assume Duckweed is present – many submerged weeds can be controlled at much lower rates.

White Cap and Sonar™ brands contain the same active ingredient.
