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

Croc-sational
Color: Blue
My tough chewer is OBSESSED with Croc. Stands up well, small particles occasionally come off but this beats going thru 3 stuffies in an hour. Good value, easy to clean and great for our 91lb pitty

Good for a few weeks for large dogs
Color: Blue
It held up for a few weeks. The arms and tip of the tail were chewed off. Had to throw it away so my dogs wouldnt eat the parts that they chewed off. It kept them busy for a while.

Dog likes it, but is very hard material around smaller dogs when he is playing and running
Color: Blue
My 22lb dog loves this chew. We have owned it just for one day. He immediately loved it and he races through the house holding it in his mouth like a grand prize.
I have concerns to the hardness of the ends of it, the material is very hard, and the tail comes to an end shape that could hurt other pets in a multidog home if it hit or stuck in them. I have two smaller chihuahua dogs, one who has lost an eye so this is something to be careful about with other dogs running with this toy. This may not affect a one dog home. Best to observe the dog while playing with it around others.

Withstands very aggressive chewing
Color: Blue
We have a very active and aggressive chewer. Items identified for aggressive chewers are “Gone in 60 Seconds”. This toy is amazing. It has withstood Jake’s many attempts to destroy it and is one of his favorites! It is not hard like acrylic but is hard rubber with some give decreasing risk of fractured teeth. Best toy yet!!!

Great chew toy
Color: Blue
I bought this almost a year go. My dog is still chewing on it! Nothing last this long with her. She is a 100lb Rottweiler that is a strong chewer.
