Pathological studies on root rot of Prosopis cineraria (L.) druce in India

摘要

The studies were undertaken to find out the susceptible age of the host plant (Khejri), optimum inoculum load and inoculum age for maximum root rot development. Five days old 'Khejri' seedlings exhibited 80 per cent mortality which was significantlyhigher than other treatments. With the increase in inoculum load, there was a corresponding increase in disease incidence. The seedlings showed maximum mortality when inoculated with 20 days old oat seed sand culture. Young seedlings were more prone to disease than the older ones.
