Is Nufarm Polaris Herbicide better than Catt Plex? Can either be used in a koi pond?
Nufarm Polaris Herbicide is only available in a 2.5 gallon jug only at this time. Both Nufarm Polaris and Catt Plex are labeled for treating cattails. We do not carry any products that are safe to be used in koi ponds at this time. We would recommend that you contact a koi pond supplier in your area or possibly your local cooperative extension office for advice on what products to use.
