Thanks for the info Kelly!
One more question from me. Since products like Rodeo require a surfactant, why don't they just put it in there in the first place? Is it different applications require different surfactants or quantities of surfactant?
Bump....anybody know the answer to this question?
There are at least three possible reasons. 1) Different uses require different surfactants. 2) The formulation is not stable long term with the surfactant, but is OK when mixed short term in the tank. 3) The best surfactant is patented by someone other than the herbicide manufacturer.
