Background: Inflorescence and vegetative malformation of mango, caused by the fungal pathogen Fusarium subglutinans, is one of the most important diseases of this crop occurring in most mango-growing countries worldwide. Malformation was first reported over a century ago in India, however, the epidemiology of disease is poorly understood. Infected vegetative shoots are misshapen with shortened internodes, and small stubby leaves. Floral malformations are also shorter, thicker, and possess increased crowded branching, resulting in major yield losses since malformed inflorescences do not bear fruit. Management of the disease is dependent mainly on sanitation, which entails removal of malformed vegetative and floral plant material.
