i'll chime in again if me I would spray with reward as mentioned just on areas that are an issue. Agree on of my favorite list of plants but disagree pond frog it is HIGHLY preffered plant for grass carp. Not all potomo this way but this one is so if eradication is desire grass carp good choice otherwise put just a few in or nto any issues cleaning this up. It is first plant eliminated when we stock grass carp.
