Abstract
Evaluation of few fungicides viz., Fuji-one (Isoprothiolene), Tricyclazole, Edifenphos, Hexaconazole and Mancozeb as seed treatment at two varying doses revealed that Fujione (Isoprothiolene) and Tricyclazole 75WP were most effective in combating the nursery blast disease, exhibiting no incidence and severity at both the doses tested at 35 DAS and a seedling vigour index of 4.0, whereas the Mancozeb 45WP proved inferior resulting in an incidence of 2.0 and 2.7% a severity of 0.9 and 1.6 per cent at both the levels of doses respectively with a seedling vigour index of 5.0.
