Pathological studies of Pestalotia mangiferae

Abstract

Pestalotia mangiferæ has been observed on leaves of Mangiferœ indica at Allahabad and Madras. The pathogenicity of this organism has been established on leaves, stem and fruits of mango and symptoms have been described. Cross-inoculations on Psidium gujava, Mimusops hexandra, Butea frondosa, Eucalyptus sp. and Citrus sp. were unsuccessful. Storage of fruits at temperatures below 8°C. prevented fruit rot. Dusting the leaves with zinc sulphate controlled the disease but similar dustings on fruits failed to control the rot.
