Frequently Asked Questions
1. How does a liquid work to control hydrilla with roots on the bottom?
A. Hydrilla Killer is heavier than water and sinks to the bottom. It is important to apply on a calm day, preferably in the day so that the hydrilla killer will catch and adhere to the hydrilla on the way down for a period of 3 hours.
2. Can I just cut the hydrilla and remove it?
A. Yes you can, however, this will cause the hydrilla to grow faster, so it is not really recommended.
3. Will your product kill other weeds?
A. Hydrilla killer is effective in controlling a broad range of algae including: Chara, Spirogyra, Cladophora, Vaucheria, Ulothrix, Microcystis and Oscillatoria.
4. How much do I apply?
