Abstract:

Roses are one of the most important and commercial ornamental flowers, grown worldwide. Black spot disease severely infects the rose crop grown worldwide. In this study, six fungicides at 0.05, 0.10, 0.15, 0.20 and 0.25 per cent concentration were evaluated by poisoned food method and it was observed that hexaconazole 5 per cent EC (Contaf) and tebuconazole 50 per cent + trifloxystrobin 25 per cent WG (Nativo) at 0.05 per cent concentration showed highest inhibition percentage. Mancozeb 75 per cent WP showed least inhibition percentage. Three micronutrients and their combinations were evaluated and among them CuSO4+FeSO4+ZnSO4 showed 55.56 per cent mycelial inhibition at 0.1 per cent concentration and completely inhibited the mycelial growth at 0.2 per cent concentration.
