An apricot tree is a small tree first cultivated in India. Unfortunately, there are many diseases related to the apricot tree, including bacterial and fungal infections.
Crown gall is a bacterial infection affecting a plant's roots and stems. A gall will form on the plant and turn very hard and dark. The plant's leaves may then turn colours and the plant may begin to wilt. Infected plants should be discarded.
Powdery mildew looks like dust on a plant's leaves. It will eventually cause affected leaves to wilt and drop off, but the apricot tree should survive.
Plum pox most frequently affects trees of fruits with stones such as apricots. Apricots may develop rings on them or leaves may have yellow veins. Over time, the tree will no longer produce healthy fruit.
Ripe Fruit Rot
Apricots are very susceptible to ripe fruit rot, which forms dark brown hard spots on ripening fruit. The fruit most likely will not drop and will stay on the tree.
Apricots are severely devastated by bacterial spots, a common bacterial disease. It affects the apricot tree's fruit, leaves and twigs. It can spread to other trees, so should be monitored closely.
