Abstract

 

The five isolates of the pathogen Phomopsis vexans formed both types of conidia i.e. a and b conidia. Both the conidia were exposed to plant parts, plant leachates, and different grades of water as well as to different carbon sources. Among the substrates, leaf promoted maximum germination of a conidia. Among leachates, leaf leachate was found best and glucose among the carbon sources was most effective in enhancing germination of the pathogen isolates.

 

Key words: Phomopsis blight, Phomopsis vexans, brinjal.
