Fast-Acting Certified Organic Alternative to Roundup® and Glyphosate

By penetrating the cell wall, shutting down the flow of nutrients and disrupting cellular processes, Prizefighter™ breaks down weeds from the inside out. Visible results are achieved within 15 minutes and it quickly kills green plant tissue on contact due to the rapid desiccation of undesired foliage. Prizefighter’s versatility makes it a useful addition to your landscaping maintenance plan.
