| dc.description.abstract | The present investigation entitled ―Studies on Cephaleuros virescens Kunze causing red rust of litchi‖ was undertaken to record the prevalence of the disease, cultural and epidemiological aspects of the pathogen and management of the disease. Red rust of litchi was prevalent in mild to severe form at various locations in five districts (Hamirpur, Una, Kangra, Chamba and Mandi) surveyed in Himachal Pradesh. Disease incidence was found to be ranging from 0 to 35.47 per cent with disease severity 0 to 47.79 per cent. Maximum incidence and severity of disease was recorded at Nagrota Bagwan, Kangra. The pathogen was isolated, purified and identified as Cephaleuros virescens. Pathogenicity of the isolated pathogen was proved by inoculating healthy litchi leaves with culture of pathogen consisting of zoosporangia and the symptoms appeared after 2 weeks of second inoculation. Out of six nutrient media tested, agarized host leaf extract medium was found to be best for growth of C. virescens. Gametangia like bodies were visualized in the culture. Temperature of 25℃ and pH 8.5 incubated under 12 h photoperiod was found to be optimum for the growth of pathogen. Temperature 32℃ and relative humidity 100 per cent was found to be optimum for symptom development under artificial inoculation conditions. Captan, mancozeb, CabrioTop®, hexaconazole and propiconazole resulted in cent per cent inhibition of alga. | en_US |
