Treating leaf anthracnose
I received the diagnosis from A&M of the disease bothering my Blue Angel. It's leaf anthracnose (Colletotrichum). Apparently, it's a common pathogen in farm land and in some types of trees I don't have. I have no idea where I got it or how. It's spread by watering or by rain.
They suggest removing all diseased leaves and spraying with fungicides (the report is in photos below). If you were removing diseased leaves, would you cut them, tear them or do you suggest another way to remove the leaves?
I'm debating throwing away the Blue Angel and a couple of others that show sumptoms. I've had problems with BA almost since I've had it and also on Radiant Edger. I see some limited symptoms on Guacamole and Blue Cadet, so they will have to be treated.
Does it make sense to just chunk the BA and the RE? They've been showing symptoms for a couple of years and I just didn't know what it was. Most of the others have very few or no symptoms. Is this a case of cutting my losses or am I going to have this problem forever anyway, so there's no point in getting rid of the plants?
