Sphaceloma fawcettii

Sphaceloma fawcettii is a fungal pathogen that causes citrus scab, a common disease of citrus trees. This pathogen is a member of the Elsinoaceae family and the Ascomycota phylum. It is known for its detrimental effects on citrus crops worldwide, leading to significant economic losses.

Description

Sphaceloma fawcettii is a fungal pathogen that primarily affects citrus trees. It is the causative agent of citrus scab, a disease characterized by the formation of corky outgrowths on the fruit, leaves, and twigs of infected trees. The pathogen is a member of the Elsinoaceae family, which includes other significant plant pathogens.

Life Cycle

The life cycle of Sphaceloma fawcettii involves several stages. The fungus overwinters in the scab lesions on the tree. In the spring, the fungus produces spores that are spread by wind and rain to new host plants. Once on a new host, the spores germinate and infect the plant, leading to the development of new scab lesions.

Impact

Sphaceloma fawcettii has a significant impact on citrus production worldwide. The disease it causes, citrus scab, leads to a reduction in the quality and quantity of fruit produced. This can result in significant economic losses for citrus growers.

Management

Management of Sphaceloma fawcettii involves a combination of cultural practices and chemical control. Cultural practices include pruning and removing infected plant material to reduce the amount of inoculum available for new infections. Chemical control typically involves the application of fungicides to protect new growth from infection.
