Through INFUSION, Captain XTR is the best available technology for the control of all types of algae. Captain XTR is optimized to increase the penetration of copper (INFUSION) into algae cells and enhance efficacy. This formulation feature is especially impactful when targeting tough to control mat-forming, colonial and mucilaginous species. Waters treated with Captain XTR may be used for swimming, fishing, watering livestock and irrigation of food and non-food crops (e.g. turf, ornamentals) during and after application.
