I have been trying to research and coming up empty. Do we know that the surfactant in roundup is ionic and not nonionic? I�m curious. Can�t seem to find the answer.


I just always assumed you needed to add your own surfactant to Rodeo to maximize the result. I add 1 ounce of a non-ionic surfactant (I use Cygnet) per gallon of spray. I use roundup for areas away from the pond without adding a surfactant and get good results.
