ABSTRACT
In vitro screening of eleven fungicides by poisoned food technique at three different concentrations showed that
propiconazole (Tilt 25 EC), difenconazole (Score 25 EC), hexaconazole (Contaf 5 EC), Copper oxychloride (Blitox 50 WP),
mancozeb (Dithane M-45 75 WP) and propineb (Antracol 70 WP) were highly fungitoxic to Alternaria alternata. Under field
condition six fungicides were evaluated against Alternaria leaf spot disease of chilli [Alternaria alternata (Fr.) Keissler] under natural environmental conditions. Minimum per cent disease intensity and maximum per cent disease control was achieved in the treatment of propiconazole (Tilt) (0.1 %) difenconazole (Score) (0.1%) & mancozeb (Dithane M-45) (0.2 %) were also proved effective.
Key words :
Alternaria alternata, Alternaria leaf spot, Capsicum frutescens, chilli, fungicides, rot.
