Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants lillies and algae control

Since Cutrine's active ingredient is copper this should not kill lilies. At heavy doses it may slow them down maybe a little "burning" of newest leaves. Otherwise lilies should reamin okay. Princep does too good of a job at nukeing the plants in the pond; denudes the whole plant community. This is primarily why the company did not try to re-register Aquazine for pond use. It ruined the plant food chain / ecosystem of ponds and EPA would not approve that as safe; too much environmental impact.
