Biocontrol potential of phylloplane bacterial antagonist against chilli anthracnose and powdery mildew disease

Abstract :

Aqueous plant extracts of Allium sativum, Azadirachta indica, Eucalyptus globules and Zingiber officinale. Allium sativum were tested against the growth of Alternaria solani and on the seed germination, shoot length, root length and vigour index of tomato at 15 per cent concentration. There was100 per cent inhibition of the mycelial growth of A. solani, and maximum percentage of seed germination (90.00%), shoot length (7.2 cm), root length (9.1cm) and vigour index (1467.2) of tomato seedlings were recorded in vitro in the presence of the plant extract of Allium sativum , tested following the method of Roll Towel method
