Monterey Vegetable & Ornamental Weeder will not kill existing weeds as it is a pre-emergent herbicide that helps to control grasses and broadleaf weeds prior to germination. Avenger Weed Killer or RoundUp would be products that you could use for weeds actively growing. You would want to be sure to not apply it to any of the vegetables as it will kill anything that is sprayed with it.
