Specify how Killzall works if sprayed on plants.
Does it spread thru stem to kill roots? If not, can you recommend product that does so?
Killzall Weed and Grass Killer is a glyphosate product that works like Round Up. It will kill weeds and grasses down to the root within 24 hours. Keep in mind that some weeds are more resilient than others any may require more than one application be done.
