What diseases are common in silver leaf maples?

Answer by  BrendaG (6111)

Anthracnose causes light brown/tan leaves, mainly shows in rainy seasons, and resembles scorch. Aphids overpower and leaves fall off. Cottony maple scales will form cottony masses on branches. Tar spot produces small black raised spots on upper leaf surfaces. Leaf blister looks like its name. Fungacides will cure serious cases if needed.
