TOWARDS THE UNDERSTANDING OF THE PROBLEM OF MANGO MALFORMATION
The extent of infection in infected trees plays an important role. In severely affected branches the infection is systemic. Fusarium moniliforme is found in all the scars, infected twigs, inflorescence axis and flowers. In infected twigs it is detected only in cortex and not in xylem or pith. However, the presence of mites is not essential for the expression of malformation in infected trees.
Mango malformation is widely distributed all over India, though the incidence is more in the North-West than in the North-East or the South. Climatic conditions may be playing an important role, resulting in the variation of the incidence of the disease. At least we have some indication that the disease is temperature sensitive.
