Evaluation of different fungicides against foliar blight complex of onion in vitro
Author(s): KK Gondaliya, SI Patel and NK Thumbadiya
Abstract: Onion (Allium cepa L.) is one of the most widely used vegetable due to its flavouring and seasoning the underground vegetable, both at mature and immature bulb stage in tropical and sub tropical countries. The foliar blight complex of onion resulted due to combined infection of Alternaria porri and Stemphylium vesicarium. Narrow spectrum fungicides viz., tebuconazole 25.9 EC and propiconazole 25 EC proved superior (84.07 and 81.94 % growth inhibition, respectively) against the combined radial growth of A. porri and S. vesicarium under laboratory condition. Rests of the fungicides were also found effective to inhibit the growth of the fungus. Among broad spectrum non-systemic fungicides, propineb70 WP resulted in 79.07 % growth inhibition and among compound fungicides, highest growth inhibition was recorded in tebuconazole 50 WG + trifloxystrobin75 WG followed by carboxin 37.5 DS + thiram 37.5 DS, carbendazim 12 WP + mancozeb 63 WP
