Killzall is a nonselective herbicide used to kill unwanted grass and weeds. Safe to use around desirable plants as long as it's not sprayed directly onto the foliage, Killzall herbicide is also safe for the soil, so you can plant in the areas you sprayed the herbicide without worry of harming future plants. Killzall herbicide concentrate must be mixed with water in the appropriate ratio to work safely and effectively.
Fill an empty aluminum, plastic or stainless steel garden sprayer with 1 gallon of water. Add 3 tbsp. of Killzall herbicide concentrate for general weed control. For tough-to-control weeds and brush, add 5 tbsp.
Put the cap on the garden sprayer and swirl it around to mix up the herbicide and water.
Spray the foliage of the weeds thoroughly with the mixture. It's not necessary to spray the stems or roots.
