This is off one of my Santa Rosa plums. I have had this on one of my other plums last year right before Fall. I have a spray program with captain , malathion and carbaryl. I still have this problem. Any help would appreciated. By the way the trees are over 3 years old.

As an older cultivar, Santa Rosa plums remain susceptible to plum leaf scald. This disease occurs when bacteria is introduced to the plant by leafhoppers, a plant-feeding insect that thrives on wild plum trees. One way to avoid the disease is to remove any wild plum trees located within several hundred yards of the Santa Rosa plum about to be planted.
