An experiment on efficacy of 12 fungicides in vitro and 7 fungicides in field against black spot of rose was conducted at University of Horticultural Sciences, Bagalkot. At 500 ppm concentration, carbendazim50 % WP, difenconazole25 % EC, thiophanate methyl70 % WP, fluzilazole40% EC and propiconazole 25 ECgave cent per cent inhibition of mycelia under in vitro. In field experiment difenconazole @ 0.1% recorded least (2.86) per cent disease index which was on par with carbendazim @ 0.1% (3.05). These treatments were followed by hexaconazole @ 0.1% (4.95), thiophanate methyl @ 0.1% (6.86) and propiconazole @ 0.1% (7.24).The highest yield of 57754 flowers /ha with highest net income of Rs. 88,106 was recorded in difenconazole @ 0.1%. Carbendazim @ 0.1% was next best with yield 53,013 flowers /ha net returns of Rs. 79325. Hexaconazole @ 0.1% was third best which yielded 52,582 flowers /ha with net return of Rs 79,064.
