Review: Product works as advertised - Works as advertised. Cattails were overtaking my pond prior to applying this product and it's safe for the fish. I apply it yearly to control over growth of cattails (Redwing Blackbirds nest in cattails) so I'm not trying to destroy ... just control growth. Note: Use a surfactant (sticker) when applying Review: Got the job done - I had previously used the product on cattails, mixing as directed. After a few days the cattails started to yellow. But it took a couple of weeks till they were cooked! The Lilly Pads were completely different. First time I’ve attempted to clear them. From reading other reviews I’d remembered a lot of them said it takes time compared to the cattails. I sprayed them along with a few stray cattails. Again after two weeks I didn’t notice much of a difference concerning the Lilly Pads. The cattails were dying. I figured it just wasn’t working or maybe I didn’t mix enough in. After the 3rd week I forgot about it. And then about 5-6 weeks in they started to disappear, big thick roots started to pop up slowly. I actually sprayed the remaining bits a few days ago. For me it was about time. End results are great! Good luck! ## Features - CattPlex Pro, the aquatic herbicide formerly known as CattPlex, delivers targeted cattail control and tackles both submerged and floating weeds ensuring the restoration of aquatic ecosystems with precision and effectiveness.
