I agree. I used Habitat last summer on several types of plants. It worked well on cattails -- all dead and no reemergence so far. It also took out the willows and a small patch (2 x 2 ft) grass at the boat landing (oooppps ). It has not worked well with the pondweed and it is not labeled to do so. If will flat kill a long list of trees and weeds and grasses so be careful and read and follow the instructions. ewest
