Abstract
Modes of survival and perpetuation of Alternaria brassicae attacking rapeseed and mustard were examined. The pathogen remained viable in diseased plant debris and seeds of infected plants which served as primary sources of inoculum. The pathogen was internally seed-borne and infected seeds resulted in damping-off of seedlings. Air-borne conidia produced on aerial parts of the infected plants were responsible for secondary spread of the disease.
