Knockout Aquatic Herbicide (5L)
Knockout Aquatic Herbicide is a low-toxicity glyphosate approved for use in and around waterways. The chemical is mixed with a surfactant (wetting agent) that makes it kinder on aquatic environments than regular glyphosate (NOT approved for aquatic environments). This product has better results on taller plants and grasses like cumbungi and spike rush.
Note: this product is NOT appropriate for submerged weeds because the chemical becomes inert when it comes into contact with water. If you are using it on floating weeds/leaves, wait for a calm day when the wind and wave action is low. We don't recommend using Knockout on azolla or duck weed, try the Aquatic Weed Killer instead.
Knockout Aquatic Herbicide is suitable for the following aquatic weeds:
- All grasses
- Alligator weed
- Cumbungi
- Phragmites
- Common reed
- Rushes
- Sedges
- Water hyacinth
- Water couch
- Water lettuce
- Waterlily
