Reward® Aquatic Herbicide

  • $139.99

Reward™ Aquatic Herbicide is used for aquatic weed control in ponds, lakes, reservoirs, marshes, drainage ditches, canals, streams, rivers, and other slow-moving bodies of water for control of aquatic weeds.

Reward is a broad spectrum non-selective, highly active kill on contact herbicide. Reward spreads quickly through the water and makes fast contact with aquatic weeds. Water-soluble, it is absorbed by target plants in just minutes, providing broad-spectrum control of floating, submerged and terrestrial weeds. 

Reward Aquatic Herbicide controls weeds by interfering with photosynthesis within green plant tissue. Plants should be actively growing for best results.

Reward contains 37.3% Diquat dibromide as an active ingredient.

Must provide a copy of your pesticide applicators license if you are purchasing this product in Michigan.

I used Reward in several spots, fortunately not my entire yard, as it killed the centipede where I spot treated it. I thought I'd used as instructed but if not, it's too sensitive and complicated for me. Reviews were so good I'll try it again under more controlled circumstances and let you know.

Product works. Packaging needs improvement.

When I opened the box, there was liquid leaking out from the lid. There was no seal, just the screw on lid. There was some brown poison on the side of the container. This product seems to be doing a great job on my small stock pond.

Reward aquatic herbicide

Reward aquatic herbicide works perfectly with the other chemicals that I mix up,and altogether they do exactly what they’re designed to do.
