Hi-Yield Killzall Aquatic Herbicide is an excellent non-selective grass and weed killer ideal for non-crop and aquatic sites. This is a water soluble liquid which mixes easily with water for foliar spray applications. This aquatic herbicide provides effective control against broadleaf weeds, many herbaceous or woody plants, annual and perennial grasses. Hi Yield Killzall Aquatic Herbicide moves through the plant from the point of foliage contact into the root system. Expect results for most annual weeds in 2 to 4 days, and 7 days or more for perennial weeds. Provides excellent control for aquatic weeds such as water lettuce, water hyacinth and cattails in lakes, ponds and ditches. One quart will cover up to 1 acre. Can be applied through most standard industrial or field-type sprayers after dilution and through mixing with water in accordance with label instructions.

Killzall Aquatic Herbicide
By Marianne on 11/23/2019
After doing a test spraying, within 3 weeks, the area I have dead grasses and weeds. I'm impressed and went out to finish spraying to the end of my property line. With the products from Do My Own, I hope to have my little lake front property looking great again.

Works very well

I live on the lake and this stuff is worth buying. I used it for the Lilly pads and milfoil grass. Saw the weeds starting to dry up in a couple days. It's been three weeks and they are almost gone. And the water was over the weeds when I applied it. Will purchase again. I mixed it a little hot!

The Hi-Yield Killzall Aquatic Herbicide is safe around aquatic life when applied as directed on the product label. The product label states, "When emerged infestations require treatment of the total surface area of impounded water, treating the area in strips may avoid oxygen depletion due to decaying vegetation. Oxygen depletion may result in fish kill."
