Bacterial canker disease of mangoes

Canker disease of mango caused by Xanthomonas campestris pv. Mangiferaeindicae. The bacterial canker disease of mango is also known as bacterial spot, leaf spot, black spot, mango blight and bacterial black spot.

Bacterial canker is a serious mango disease that may result in a 50% to 80% reduction in fruit production.

The bacterial canker disease is rapidly spreading during rainy days. The disease is spread through the infected planting parts. When the fruits are in bunches the bacterial disease is spread through the contact with each other.

The disease is found on leaves, stem, branches and fruits. This disease is mainly seen in the form of irregular necrotic patches (cankerous patches) with brown color. Fruit symptoms appear as small water-soaked spots on lenticels. These spots later become star-shaped, erumpent, and exude an infectious gum.

Severe fruit infections will cause premature fruit drop. Less severe infections reduce fruit quality and allow entry of other pathogens.
