Hi-Yield Killzall Aquatic Herbicide, 32 oz

Weeds along a pond bank, a ditch or a fence line can take over fast and crowd out the grass you want to keep. Hi-Yield Killzall Aquatic Herbicide goes after listed annual and perennial grasses, broadleaf weeds and woody brush, so you can clear the edges of a pond or drainage area without spending the whole weekend on it. It's made for aquatic and other non-crop sites, which covers much of the rough ground around a farm or rural property.

Canadian thistle, chickweed, dock, foxtail, pigweed and ragweed are among the weeds it controls. It also works on the stumps of cut brush, on wildlife habitat restoration and management areas, and on winter annual weeds in dormant Bermuda grass. One 32 oz bottle covers up to one acre, so you can plan the job before you mix it.

What it's for

Not every weed killer belongs next to water. Products made for aquatic and other non-crop sites are built for the places where grass, brush and weeds grow near ponds, ditches, fence lines and other ground that isn't planted with crops.

Choose this for clearing the edges of a stock pond, keeping a drainage ditch open, cutting back brush and treating the stumps after you cut, or knocking down winter annual weeds in dormant Bermuda grass. It suits a landowner with a few acres of rough ground and a sprayer to put it down. Keep it for the non-crop jobs it was made for.

How to use it

• One 32 oz bottle covers up to one acre. Use the application chart in the directions to match the rate to your target weeds.
• Read and follow the directions printed on the product before every use.
• Keep spray off desirable plants, and check the directions for the conditions that fit your job.
• Clean the sprayer thoroughly after use, and keep the rinse water out of ponds and ditches.

DOMESTIC ANIMALS: This product is considered to be relatively nontoxic to dogs and other domestic animals; however ingestion of this product or large amounts of freshly sprayed vegetation may result in temporary gastrointestinal irritation (vomiting, diarrhea, colic, etc.). If such symptoms are observed, provide the animal with plenty of fluids to prevent dehydration. Call a veterinarian if symptoms persist for more than 24 hours.

Do not contaminate water when disposing of equipment washwaters. Treatment of aquatic weeds can result in oxygen depletion or loss due to decomposition of dead plants. This oxygen loss can cause fish suffocation.
