So this spring we've had awful weather, far cooler than normal and not a lot of sun/lots of grey or rainy days. A number of my Chinese Elms have "black spot" - clearly a fungus or a disease. Trying to look into it the "official" "black spot" affects the rose family. So I guess there are some terminology issues here. It's gotten pretty bad in a couple of them but no other trees are affected.
Looking for any tips/suggestions on a: what it is and b: treatments. Other than the standard fungicide applications. I think I currently only have Daconil (which I've applied once so far) and a Copper Fungicide.
I've also seen Mancozeb? mentioned.
Should affected leaves be cut off - or just treated?
