Asulam is primarily used as a selective herbicide, especially in the control of bracken fern in pasture and forestry areas. It is effective in managing broadleaf weeds and certain grasses without harming desired vegetation when applied correctly. Asulam is commonly used in non-crop areas and is valued for its systemic action, meaning it is absorbed by the plant and moves through the tissues, providing effective control of above-ground growth. It has also been used in some agricultural settings to manage weeds in crops like asparagus and ornamental plants. Due to its mode of action as a foliar-applied herbicide that inhibits plant growth by interfering with amino acid synthesis, it is particularly useful in integrated weed management programs. Its use is often seasonal and targeted, minimizing environmental impact while effectively suppressing invasive or problematic plant species.
