It Did The Job

It took quite a few applications, but this product absolutely worked to remove the numerous spreading cattails we have in a swampy part of our large yard. Adding the surfectant to make this product stick to the vegetation is beneficial. We added that application as recommended.

Give it a couple of weeks

It took a couple of weeks to work, but the pond grasses are now yellow and dead.
