Introducing a paradigm shift in weed control. Consistently effective results while simultaneously improving the microbiome of the soil. FireHawk Bioherbicide combines state-of-the-art advanced delivery technology, developed by using cutting-edge scientific research in combination with naturally derived ingredients. FireHawk does not contain glyphosate or any other type of synthetic herbicide ingredient. The mode of action for FireHawk Bioherbicide is desiccation by dehydration. This happens by stripping away the waxy outer layer of the weed or plant sprayed, breaking down its cell walls, allowing the moisture and nutrients to escape. Dr. Rick Haney describes this as "death by drought". This is what provides "Soil-Friendly Weed Control". FireHawk provides consistent performance on a wide variety of plant species. In addition to being an effective, non-selective contact herbicide, FireHawk is completely biodegraded and beneficial to the soil microorganisms. Weed scientists tell us it is nearly impossible for weeds to develop resistance.

Independent research has proven that FireHawk Bioherbicide is beneficial to soil health.

FireHawk Bioherbicide provides consistently effective weed control while improving soil health.
