Mychorhizal Fungi and Hydroguard

I was reading that the bacteria in Hydroguard and Southern AG garden friendly fungicide eats fungus. I was wondering if it was selective or if it will eat the Mychorhizal Fungi as well?

I guess that makes sense, and they would not be advertised so strongly side by side if there was a negative interaction. I have never had a need for the root inoculant so I am a bit wary.
