The main disease of Nanking cherry is leaf blight.
The main symptom of the disease is the yellow of the lower leaves. And it shows an upward trend and gradually turns yellow, which gradually causes the whole plant to die. Leaf blight often occurs in old plants, which is caused by abiotic factors. The induced cause is that the old stem germinates new branches in spring, but the new branches do not get enough water supply, which causes the leaves below to wither and die. After the death of the lower part, the new branches above have no water absorption source, so the whole plant eventually withers and dies.
Control method is very simple, that is, in spring, to provide sufficient water, maintain the soil and air humidity, although not completely restored, but can achieve the role of mitigation.
