The herbicide is effective to some vicious weeds such as Microstegium vagans,Miscanthus sinensis, Mallotus apelta, Thysanolaena maxima, Blechnum orientale, Pteridium aquilinum var latiusculum, Gahnia tristis, Miscanthus floridulus and Imperata cylindrica. The chemical weeding rate is up to 94 7%, it is much higher than that of the other herbicides.
