Hi-Yield Killzall Weed and Grass Killer Concentrate 1 gal

When you need to clear a large area of unwanted vegetation, a jug of ready-to-mix concentrate goes a lot further than the small spray bottles on the shelf. Hi-Yield Killzall Super Concentrate packs 41% glyphosate into a 1-gallon container that treats up to 25,600 square feet once diluted, making it a practical choice for driveways, fence lines, gravel beds, and other spots where nothing should grow back.

This is a non-selective, post-emergent herbicide, meaning it goes after weeds and grass that have already sprouted rather than preventing new ones - and it doesn't discriminate between broadleaf weeds and grass, so keep it away from anything you want to keep alive. Best applied in spring when weeds are actively growing, it's suited to lawn and garden projects and larger properties where buying concentrate instead of pre-mixed spray saves both money and trips to the store.
