Know before you buy
Yes, this product is specifically labeled for aquatic use, making it safe for managing vegetation in and around water bodies when applied according to the label instructions.
Hi-Yield Killzall Aquatic is a non-selective herbicide, meaning it will damage or kill any green plant tissue it contacts. You should be extremely careful to avoid overspray or drift onto your lawn, flowers, or ornamental shrubs.
Yes, it is highly effective for woody brush and vines. For larger trees, it can be used in a cut-stump application to prevent regrowth.

Yes, this product is suitable for controlling winter annuals in dormant Bermuda grass. Ensure the grass is fully dormant before application to avoid damaging the turf.
