Its chemical name is (RS)-2-[4-(6-chloroquinoxalin-2-yloxy)phenoxy]propionic acid 2-tetrahydrofurfurylmethyl ester, and it is a highly effective, broad-spectrum, easily degradable herbicide. It is quickly absorbed by gramineous weeds and conducted throughout the entire plant, inhibiting fatty acid synthesis and thereby killing the weeds. It is suitable for use in dicotyledonous crop fields such as potatoes, soybeans, rapeseed, and cotton, for the prevention and control of various gramineous weeds including barnyard grass and green foxtail.
