Abstract:

Bottle gourd (Lagenaria siceraria) is one of the important cucurbitaceous vegetable crop being grown both during warm and rainy season in northern parts of India. It has wide genetic diversity and is grown throughout the tropics and subtropics of the world. Bottle gourd is prone to various fungal bacterial and viral diseases. Among various fungal diseases Anthracnose, Downy mildew and Cercospora leaf spot are widely prevalent in different bottle gourd growing areas. Anthracnose caused by Colletotrichum lagenarium (Pass.) Ellis. and Halsted is of major economic importance. Keeping in view the importance of this disease in this region, the present investigation was carried out under laboratory condition in the department of Plant Pathology during 2016 at CCS, HAU, Hisar . In the variability studies, potato dextrose agar medium was found best medium for growth of Colletotrichum lagenarium. The fungus grew well at 6.5 pH and 30ᵒC temperature, whereas, minimum growth of fungus was observed on oat meal agar medium at 7.5 pH and 35ᵒC temperature. Among various isolates Karnal (CL2) and Kaithal (CL3) isolates were found fast growing. Least growth was observed in Yamuna nagar (CL5) isolate. Maximum conidia size and sporulation was recorded in Karnal (CL2) isolate grown on potato dextrose agar media at 35°C temperature and 6.5 pH.
