FIREHAWK BIOHERBICIDE What We Do FireHawk Bioherbicide is a groundbreaking solution for weed control that combines advanced delivery technology with naturally derived ingredients for fast and effective results that last, even on glyphosate resistant species. Its unique formula breaks down the waxy outer layer of weeds, softening the cell walls and leading to effective desiccation and plant death. With a 94-98% efficacy on most annual species, FireHawk's active ingredient, nonanoic acid, is readily broken down into carbon dioxide and water in the soil. Customers report extended durations of control and a reduction in overall weed pressure so that land management becomes easier with each treatment. FireHawk provides professional-grade control from a 50X dilution rate.
