Abstract:

Black shank, Phytophthora parasitica var. nicotianae is a major disease of tobacco results in considerable loss of the crop. An investigation was carried out to screen the different fungicides to inhibit the growth of black shank pathogen. Among eight fungicides tested at different concentrations, 0.1 per cent of Trifloxystrobin + Tebuconazole, Fenamidone + Mancozeb and Metalaxyl + Mancozeb were showed cent per cent inhibition and found effective over all the tested fungicides. Management study under field conditions was carried out during kharif 2016, revealed that the treatment with Fenamidone + Mancozeb and Cymoxanil + Mancozeb found effective in reducing the disease incidence of 19.05% and 23.02% with highest green leaf yield (10596.71 and 9920.63 kg/ha), cured leaf yield (1246.67 and 1167.13 kg/ha) and top grade equivalent (872.67 and 700.28 kg/ha) followed by Azoxystrobin and Metalaxyl Mz over untreated check. All tested fungicides were drastically reduced disease the incidence and showed a tendency to increase tobacco yield over the untreated control.
