1. Spritflo (for ponds with no outflow) – liquid that is poured and spreads throughout the entire body of water, offers extended control.
2. Hydrothol (for lakes) – granules that are broadcast over the plants.
3. Aquathol K/Super K (for ponds or lakes) – liquid that is diluted with water and sprayed or granules that are broadcast over the plants.
4. Dibrox (for ponds or lakes) – liquid that is diluted with water and sprayed over the plants, fastacting. Will offer some control.
