Fungicides against false smut disease

In the present study three fungicides viz., copper oxychloride, copper hydroxide and propiconazole and five bioformulations viz., Biotime, TNAU-Pf1, G-Derma, G-Pseudo and Taegro Eco were evaluated in vitro on the rice false smut pathogen Ustilaginoidea virens during 2017.

In the present study nine fungicides were evaluated against the false smut disease of rice during kharif-2016. Among the different fungicides tested azoxystrobin (18.2 %) SC + difenconozole (11.4 %) SC and metiram (55 %) WG + pyraclostrobin (5 %) WG @ 0.1 per cent recorded the least disease severity of 1.85 and 2.52 per cent respectively, followed by propiconazole 25 EC, Azoxystrobin 25 % SC, Difenconazole 25 % EC, tebuconozole 250 EC and flusilazole (25 %) SE + carbendazim (12.5 %) SE showed better efficacy at 0.1 per cent and enhanced the paddy yield under field condition.

The efficacy of six different systemic fungicides and two combi-products were evaluated for inhibition of growth of pathogen at three different concentrations. Among systemic and combi-products fungicides were evaluated, the cent per cent inhibition was observed in Propiconazole 25 % EC, Tebuconazole 250 EC, Azoxystrobin 18.2 % + Difenconazole 11.4 % SC and Tebuconazole 50 % + Trifloxystrobin 25 % WG at all the concentrations.

False smut disease caused by Ustilaginoidea virens (Cooke) (Takahashi) is a grain disease of rice that converts whole grain into powder (smut balls) form. Disease infestation leads to sterile spikelets and reduction in 1000 grain weight. Considering the importance of disease the experiment was carried out to assessment of IDM module with Propiconazole and Carbendazim in rice through on field trials (OFT) against false smut disease in Kabirdham district of Chhattisgarh.
