The toxic effects on other plant and animal species has not yet been adequately tested and it may move into nearby aquatic communities if applied in close proximity to such areas. As always, read all herbicide labels before using herbicides . The decline of these once widely-scattered forests has brought about a mass effort to restore degraded sandhills. Due to the small extent and fragmented nature of these forests, restoration efforts will likely become increasingly important for the conservation of this upland ecosystem. Although hexazinone can be an important precursor to prescribed burns, it cannot replace them.
Fire is necessary for longleaf pine and wiregrass regeneration .
Hexazinone has been shown to release longleaf pine seedlings and wiregrass, and to aid in the reintroduction of scrub oak populations without damaging other woody and herbaceous vegetation. Additional experiments must be conducted on application rates, timing, and patterns of hexazinone application to refine this restoration technique. Until this informaiton is available, it is recommended that hexazinone rates ranging from 0.75 to 1.50 lbs per acre be used. Granular formulations of hexazinone should be avoided because they can damage the herbaceous plant layer. When the above rates are used, hexazinone may serve as an important tool in restoring sandhill communities.
