The New Standard for Aquatic Weed Control in Canals

Captain* Aquatic Algaecide

Captain Captain is a premium chelated copper algaecide that provides economical and effective control of algae in irrigation ponds and canals. The chelating properties in Captain result in enhanced copper exposure to algae with improved performance when compared to copper sulfate treatments. Captain can be applied as a surface spray or a metered drip application to static-, low- and high-flow canals. Water treated with Captain may be used for irrigating turf, crops and ornamental plants and for livestock watering during and after treatment. There are no drinking water or fish consumption restrictions with Captain-treated waters.
