Can anyone Identify this foliar issue. It is on approximately 40% of the foliage on a 100 year old maple that has been topped about 15 years ago. The foliage started this year looking very "wilted" and then began to develop this browning/spotting on the leaves. Only a few hours after removing the foliage it had already begun to wilt. The majority of the "scorching" appears on the outer edges of the leafs. I did also notice a minor aphid problem on the leafs as well.
