Mycelium is very important to agriculture. Every plant has different threats, but I'll use apple trees because I have those. Phytophthora rot is referred to as a fungus but actually is not. Apple scab can be mitigated with a biological control (read: natural predator) and apple rust is solved by proper spacing away from conifers (don't plant an apple orchard within 4-5 miles of a juniper forest) or simply removing galls from affected cedars. Unlike Phytophthora, both of those are a certain kind of fungus which has a different relationship with its host than mycelium does.
Somewhat non-sequitur, we also grow mushrooms. Throwing spent mushroom cakes into my worm bin is an actual super power in composting. It breaks large things down that the worms won't go after so that they're small enough that the worms do go after them.
