Asulam CAS 3337-71-1 is a systemic carbamate herbicide, usually used as its sodium salt (asulam‑sodium). It is absorbed by foliage and roots, translocates within the plant, and inhibits dihydropteroate synthase to block folic acid synthesis, resulting in the control of perennial weeds, ferns, and grasses.
