Assessment the Incidence and Per cent Infection of Anthracnose (Colletotrichum capsici) in Dry Chilli Fruit Samples

摘要

Anthracnose of chilli caused by Colletotrichum capsici (Sydow) Butler and Bisby is an economically important disease of chilli affecting both fruit and seed quality. To determine the per cent seed infection, germination and per cent micro-flora associated with seeds of twelve dry red chilli samples were collected from twelve locations belonging to seven states of India viz., Rajasthan, Himachal Pradesh, Assam, Karnataka, Gujarat, Madhya Pradesh and Andhra Pradesh. These seed samples were subjected toassess the incidence of anthracnose experiment was conducted in the laboratory by growing on blotter paper. The results revealed that anthracnose severities in these samples were ranged from 4.1 per cent in "Guntur-Teja" of Andhra Pradesh to< 34.0 per cent in "Pusa Jwala" from Jaipur (Rajasthan). Infected chilli seeds-were subjecting to blotter method showed significant variations in seed germination and yielded various fungi. The maximum seed germination 85.0 per cent was recorded in Guntur-Teja while, minimum 52.5 per cent was in Pusa Jwala and Fatki chilli respectively. It was also recorded that the maximum (30.0%) fungal seed association was of C. capsici followed by Aspergillus (6.46%), Cercospora sp (5.0%), Alternaria sp (4.17%) and 3.96% by Penicillium sp across different chilli cultivar seeds.
