This is a question for anyone who can answer it.
I have been using a silicone surfactant (Silwet, 2 fluid ounces per
100 gallons) with my NAA chemical thinner, and this produces excessive
foaming. So I add a proprietary foam killer (Fighter F) to suppress the
foaming enough to spray out to the bottom of the tank. I have been
wondering whether addition of the foam killer is negating the intended
effect of the surfactant, namely, to improve foliar uptake of NAA. Is
the surfactant wasted when it is balanced with foam killer?
