Poison Ivy / Vegetation Killer 1 cup salt 8 drops liquid detergent 1 gallon vinegar Combine the salt and vinegar in a pan and heat to dissolve the salt. Cool the vinegar, add the detergent, and pour some of the liquid into a large spray bottle. Spray the vegetation. (You can also just pour the mixture onto the weeds.) Refill the spray bottle as necessary. Note that this formula will kill all the vegetation, so make sure that you are only spraying the plants you want to kill. If you need to use a lot of this spray, avoid spraying it near wells, as the salt can leach into your water supply. If you have to kill Poison Ivy near Plants you want to keep just use a Plastic Tray held upright on the ground to Shield what you don't want Sprayed, a Large Plastic Jug with the top & bottom cut off, like a gallon Milk Jug is Great for this. Place it over the Small Poison Ivy Plant & it will only affect the Ivy its self.
