The anthracnose of chilli caused by Colletotrichum capsici, is a serious widespread disease in India and a limiting factor for profitable cultivation and seed production of chilli. Present experiment was aimed at studying the efficacy of various botanical extract on the mycelial growth, germination and seedling vigour of C. capsici. All the twenty botanicals at 10% concentration that were tested were found effective in inhibiting the mycelial growth of the pathogen with per cent inhibition ranging from 6.67 to 60.19%. Among different botanicals tested, Aegle marmelos, Eucalyptus globules, Polyalthia longifolia, Allium sativum, Zingiber officinale, Allium cepa, Carica papaya and Curcuma longa were found superior as compared to other treatments and control. A. marmelos recorded the highest inhibition of 60.19% with a radial growth of 3.58 cm. The least inhibition was recorded from Duranta repens (7.78%) and Bougainvillea spectabilis (6.67%) with a radial growth of 8.3 and 8.4 cm. The most promising botanicals (eight) were selected for further evaluation on the seed germination and seedling vigour index. Maximum per cent seed germination and seedling vigour index was observed in seeds treated with extract of garlic with germination per cent of 94.67% and vigour index of 747.73. Among all treatments, maximum root/shoot length and vigour index was found by A. sativum and A. marmelos treated seeds.
