Yeah I know you aren’t interested in trunk diseases, but I ought to be, so that is why these are going here. Esca apoplexy sounds impressive too, so you now have that going for you too.
imw asked about this particular disease in 2015 –
Looks like Esca is part of a family of fungi affecting the woody parts of plants and spreads its spores during the spring and fall rainy season and attacks open wood wounds from the pruning cuts. This seems to be true for Eutypa Dieback (which I had heard of) and also Botryosphaeria dieback, and Phomopsis dieback (which I hadn’t); these pathogens are part of the Diatrypaceae family.
