Bacterial spot usually develops more slowly and the new spots have a water soaked ring around the spot. Bacteria need a previous infection to start from. And the bactieria need warm moist rainy misty weather. Wish I could help more.
Thanks again Riggle,
Yea, think Bacterial spot fit for one I remember the tree doing this last year now.
But no where as bad this time of year???
I was told to start the copper fungicide when the leaves fall to prevent this so we'll see next year, plus getting rid of this cocktail of Immunox, Malathion, Liquid seven and Captan and finding me some Imidan for next season.
