View Full Version : Fungicide and Surfactant

I generally use Lesco's 90/10 surfactant with my fungicides but have though about using MSO instead. Anyone use anything different. I'd like to have Li-700 but can't find a vendor close by.

My favorite is a silicone-type surfactant--similar to lesco Hawkeye (about $50 per half-gallon). Very good, and more concentrated. But I used it mainly for weed control. Also similar to Garrco "Drench" a non-ionic silicone surfactant which mentions fungicides on the label.
The idea is to spread it out on the leaf surface, so the solution does not bead-up and run off waxy leaves. Nor run off vertical leaf blades.
You probably want the solution to spread out and form a thin film on the leaf surface and dry in place within a few minutes.
Spray some water on a plant (or a waxy or vertical plant leaf) and then add a few drops of wetting agent and spray a nearby leaf. Study the different appearance carefully.
I did that and showed photos last year, but I am not sure if I can find the link at the moment.
Wait found the link--within the time limit --I think. edit.
