Hi-Yield Killzall concentrate is a nonselective, post-emergent herbicide for lawn and garden renovation or spot treatment of annual and perennial weeds. The active ingredient is 41 percent glyphosate, which translocates through the plant from the foliage to the roots and kills the plants and its roots. Best results are obtained when the temperature is above 60 degrees Fahrenheit, weeds are actively growing and the winds are calm. Generally, mornings and evenings have more calm winds to prevent drift of the herbicide to desirable plants.
