I have been hearing about the benefits of applying fulvic acid foliar applied and how it can increase fungicide and foliar nutrient efficacy among other benefits. I want to try mixing in fulvic acid with my fungicides Next season. I have been using a non-ionic surfactant with my applications. If I mix in fulvic acid, should I also use a non-ionic surfactant? From what I have read, fulvic acid acts like a surfactant. Does anyone have any experience with this?

Always do a jar test. Mixed with 10-34-0 liquid starter fertilizer and it was not compatible with a dry fulvic acid.

We market a fulvic acid￼ as well as a NIS. We recommend that you use both.￼￼

I think you will see better results using it with a foliar instead of pesticide. It has a CEC of like 1400 and acts like a chelator with nutrients.
