Sphaceloma mangiferae

Sphaceloma mangiferae is a fungal pathogen that causes a disease known as mango scab in mango trees. This disease is prevalent in many mango-growing regions around the world, including parts of Asia, Africa, and South America.

Overview

Sphaceloma mangiferae is a member of the Elsinoaceae family of fungi. It is a biotrophic pathogen, meaning it derives its nutrients from living plant cells. The fungus primarily affects mango trees, but can also infect other members of the Anacardiaceae family.

Symptoms and Impact

The primary symptom of infection by Sphaceloma mangiferae is the appearance of scabs on the fruit, leaves, and twigs of the mango tree. These scabs are initially small and circular, but can grow and merge to cover large areas of the plant's surface. The disease can cause significant yield loss in mango orchards, as infected fruits are often unmarketable due to their unsightly appearance.

Management

Management of mango scab involves a combination of cultural practices and chemical control. Cultural practices include pruning and destroying infected plant material to reduce the amount of inoculum in the environment. Chemical control typically involves the application of fungicides, particularly those containing copper, which has been shown to be effective against Sphaceloma mangiferae.

Research

Research into Sphaceloma mangiferae is ongoing, with scientists seeking to better understand the fungus's life cycle, mode of infection, and resistance to fungicides. This research is crucial for the development of more effective management strategies and the protection of the global mango industry.
