>So fungi is rubbed on the leaf to develop coffee rust?
Yes, and it develops as much coffee rust as the infected leaf you extracted it from even though you only use a tiny amount of actual fungal material. If you extract snake poison from someone bit by a snake and apply it in a healthy individual, the healthy individual will not have as strong symptoms as the original individual. Maybe poison can cause chain reactions but overall you'd expect nonliving toxins to have a much greater proportionality between quantity of contaminant/severity of symptoms compared to a parasite, which replicates itself. What you see in the healthy coffee leaves is a lot of rust with only a tiny quantity of contaminant. And not only that, but the contaminant are the signs of the fungi, so you have to assume that all of the symptoms developed by the healthy plant came from whatever quantity of toxin entered the fungus, was not yet decontaminated and got into its reproductive tissue.
Besides, that creates more questions about the fungi. By what you postulate it should be possible to have coffee rust without any of the fungi, though that is never observed. What is observed is that it only lives through that detox reaction as it only ever appears where there's coffee rust, and as much of it appears as there are symptoms. But how does it get to a leaf with the toxin? You've already ruled out known transmission methods. You could say it was laying dormant in the leaf, but if you grow 10 new coffee bushes from the first one's seeds, all of the leaves of all of the new bushes exhibit the same behavior when contaminated. Thus the fungi on the first bush had to be metabolically active, reproducing itself. Yet it couldn't be because observably it's only active wherever there's coffee rust.
Does the fungi come with the toxin itself and both of them were previously within the insect? Can you chemically identify the toxin? Can you identify the insect? Is the occurrence of coffee rust lower in areas subject to measures which do insect control but don't affect fungi? If you do identify the insect and control it you'd also extinguish coffee rust, that would be lucrative and there'd be a lot of demand for it.
