Yes Alina, the amount of fungal spores in the air is not provable yet (to my knowledge) and there are many other variables - I do agree on that one.
It's just that I've been reading a lot about the issue (CODIT) and have seen some awful damage in the many years that I worked at a tree nursery, that I've come to this conclusion. We did experiment (not scientificely) and painting large wounds in those cases was never beneficial to the trees. Small wounds however, did sometimes benefit when the weather had been dry.
As I said, this is only my opinion so hopefully some others will let Elsapelle know what they think.
