Efficacy of Tebuconazole 25%WG against blast and sheath blight diseases of rice in Central Western Ghats of Uttar Kannada District

A new molecule Tebuconazole 25% WG was tried against blast and sheath blight diseases of rice during wet season 2010–11 and 2011–12 in Paddy Research Station, Malagi. The two years results revealed that, Tebuconazole @0.2% has significantly reduced the blast (17.72%) and sheath blight (10.24%) incidence and correspondingly increased the yields (41.40 q/h). The maximum blast (62.07%) and sheath blight (28.16%) was recorded in untreated control plots with lower yields (22.96 q/h). Hence, Tebuconazole @ 0.2% can be recommended as an alternate molecule to existing fungicides for effective management of blast and sheath blight diseases of paddy.
