Abstract
Corynespora cassiicola (Berk and Curt) Wei, incitant of leaf spot of brinjal, survives at the room temperatures (28–30° C) for a period of 4 months in infected dry leaves, in infected dead stems for 10 months, and for 11 months in chicken mesh wire house where natural diurnal fluctuating temperatures prevail. Masses of bulbous conidiophore bases appearing like sclerotial bodies, conidiophores and chlamydospores may also help in the survival of the fungus. The weed hostsCroton sparsiflorus Mor.Leucas aspera Spr,Ocimum sanctum L.,Solanum nigrum L., andDigera arvensis Forsk, may act as additional reserviors of inoculum for the disease spread. The fungus survives on chilli crop during summer and this may also serve as primary source of inoculum in July for brinjal crop.
