The Wick Weeder weed control tool uses a swipe applicator that is ideal for use around flower beds, fences, buildings, etc. for a controlled application of herbicides or horticultural products without the risk of drift. Fill the handle with products such as Roundup, Horticultural Vinegar, Safer's Top Gun etc. You are then ready to kill some weeds. When you are finished using the Wick Weeder, rinse it out and hang it up in a safe place to dry.
