My Asian pears have those yellow white spot on many leaves, any idea what’s the problem?
The black spots look a lot like the Fabraea leaf spot I have had. If you let it progress unchecked it will defoliate the tree and no fruit next year. I have used mancozeb (early season only) and immunox against it.
