Its chemical name is 2,6-dinitro-N,N-di-n-propyl-4-trifluoromethylaniline, and it is a pre-emergence herbicide with outstanding performance. The herbicide is absorbed during the process when weed seeds germinate and pass through the soil layer. It is primarily absorbed by the seedlings of gramineous plants and the hypocotyls of broad-leaved plants, and can also be absorbed by cotyledons and young roots, but not by the stems and leaves after emergence. It is used to control annual weeds in cotton and forage bean fields.
