The active ingredient in FireHawk Bioherbicide is nonanoic acid, a fatty acid that we optimize for efficacy. It affects only the green tissue sprayed—breaking down the green, actively growing plant tissue it directly coats. Because it does not move through the plant or remain active in the soil, FireHawk provides fast, visible burndown, giving precise control over the treated area.

A bioherbicide is a weed control product derived from naturally occurring compounds. FireHawk Bioherbicide is powered by nonanoic acid, a fatty acid that we optimize for efficacy. When sprayed on the green parts of the plant it breaks down the outer cell membranes, causing the plant cells to collapse and dry out quickly. The result is a fast-acting, non-selective contact herbicide that only affects the green parts of the plant. Learn more for your application → Home & Garden | Professional Landscape | Agriculture
