...wait, hold on. Question. How is Goliath's flamethrower going to deal with the Acalya? Unless the flame is fully capable of atomizing breakouts and latent spores, hes just going to melt the solid crystal structures into a liquid form. Quartz melts at 1610 Celsius, and I can assure you, the Acalya are much harder than that. But the "plague" the Acalya carries is still active. So, instead of poisonous trees, you'd have poisonous slag.

It depends on the chemical and physical composition of Acalya.

I assume there must be a reasonable degree of complexity to Acalya to be biologically active in the way described. Acalya is optimised to operate at ambient temperatures. Melting it (2000 C was my estimate for a thorough melting) should be adequate to destroy this higher order structure. Glass transition temperature, recrystallisation into different crystal phases and whatnot.

2000 C liquid phase with an oxygen-containing atmosphere is also an excellent place for chemical reactions to occur. Acalya, being biologically active, must be more complicated than, say, pure silica, so there are probably a bunch of things Acalya can be chemically transformed into. If Acalya contains any carbon whatsoever, it will also burn at those temperatures.

Also of note, melting it is far more effective at stopping the Acalya than smashing it, which is what everyone else has been trying to do.

Even if Acalya survives melting, the resultant slag will have a much lower surface area than a forest and thus produce spores much more slowly.

If that still isn't adequate, then I can have Goliath heat the Acalya to whatever temperature is needed to destroy it. Goliath has in excess of 50 GW of thermal energy to throw around with that flamethrower. It all becomes a trade-off between temperature and rate of forest clearing.

If that [i]still[/i] doesn't work (or if the temperatures required are prohibitive for large-scale work), then I'll have Teknall change tactics. He has more options.

P.S.

By the way, where is this Acalya forest anyway? Just curious is all.

The areas marked in blue are the major outbreaks.
