  • Applications

    Asulam (CAS 3337-71-1) is the active ingredient in selective herbicides used for weed control in agriculture and horticulture, with particular effectiveness against bracken and other broadleaf weeds; it is applied as a systemic foliar spray, allowing uptake and translocation to suppress growth; typical applications include agriculture (field crops and pastures), production of ornamental plants and nurseries, forestry and land management to reduce bracken density, and non-crop vegetation management in rights-of-way and industrial sites; formulations vary and use is governed by local regulations and product labels.
