Effect of temperature and relative humidity on infection efficiency and lesion of fruit rot disease of eggplant caused by Phytophthora nicotianae var. nicotianae.

Following inoculation with mycelial, zoospore or cyst suspensions of P. nicotianae var. nicotianae, aubergine (Solanum melongena cv. Pusa Purple Oblong) fruits were incubated at different temperatures and % relative humidities. The mycelial suspension was more effective than zoospores or cysts in causing infection. Subsequent lesion expansion was maximum at 30 deg C at 80-100% relative humidity (RH). No infection occurred when the temperature was below 20 deg C or above 30 deg C and when RH was below 60%. The results indicate potential high incidences of Phytophthora rot of aubergine during the monsoon months of West Bengal.
