Abstract:

The present investigations were carried out in the Plant Pathology Laboratory of Department of Fruit Science, Punjab Agricultural University, Ludhiana from 2014 to 2016. The anthracnose disease produce brown to pin head black necrotic lesions on tip and margin of leaves, brown to tan sunken circular spots with minute stroma in centre of lesion on green fruits and dark brown to black water soaked lesion causing browning and rotting of ripe fruit The Rhizopus rot infection start on ripe fruit with secretion of red juice from fruit tissue which later covered with white fuzzy mycelium. For pathogenecity test, pin prick method of inoculation on leaves, green fruit and ripe fruit was found better than spray method. On the basis cultural and morphological characteristics and identification report of Indian Type Culture Collection (ITCC), Division of Plant Pathology, Indian Agricultural Research Institute, New Delhi, the causal agent of production of anthracnose type symptom was identified as Colletotrichum gloeosporioides. Acervuli are not produced in culture but on plant tissues with black and erect setae. A temperature of 25°C found significantly effective in favoring the mycelial growth and below 15°C failed to support the growth of the pathogen. Significantly highest sporulation occurred in 15 days old culture of the pathogen. The spore germination was found significantly better at 25°C after 4 hours of incubation and cent per cent after 16 hours of incubation.
