Item Information

Tips for Success:

Rated 5 out of 5 by from Great Product Great product for maintaining a pond with a natural bottom where unwanted aquatic weed growth is found
Date published: 2020-03-20
Rated 3 out of 5 by from Sort of OK So far did very well on Lotus and Cat Tails BUT seems to have NO EFFECT on Duckweed. Duckweed was the main reason for the purchase. Also way more expensive than other vendors
Date published: 2019-09-21
Rated 4 out of 5 by from Good product Killed surface weeds relatively fast. It murders ground grasses around my pond. Not sure if it effects grasses below the surface.

I am looking for a product to kill cattails in a pond, & don't want to harm the fish, turtles, & frogs. Will this product do the trick?

Asked by: cowgirljoey
Weedtrine-D would eventually kill cattails. In most cases the damage to fish and wildlife is minimal if any when used properly.
