Studies were conducted during <i>kharif</i> 2006 and 2007 for the management of blast disease of finger millet through fungicides, bioagents and varietal mixtures. Results revealed that seed treatment with <i>Pseudomonas fluorescens</i> Pf 2 (@ 0.6%)+its two foliar sprays (@ 0.6%) followed by two sprays of hinosan @ 0.1% were significantly most effective in reducing blast disease. The treatments provided 81.69 and 77.72 per cent yield increase over the control, respectively. In order to extend the life span of VL 149 (resistant variety) as well as reduce blast damage in the local, but preferred variety, the varieties were sown in different combinations. Results revealed that the 1:1 mixture of PRM 1 (V<sub>1</sub>) and VL 149 (V<sub>2</sub>) varieties, was best, wherein incidence of neck blast (0.84%) and finger blast (10.42%) diseases was lesser than both the varieties, individually. The treatment provided 96.48 and 94.14 per cent neck blast control over V<sub>1</sub> and V<sub>2</sub> varieties, respectively, while, it provided 80.06 and 69.52 per cent finger blast control over V<sub>1</sub> and V<sub>2</sub> varieties, respectively. In addition to disease control the treatment also increased the yield by 36.56 and 19.51 per cent over V<sub>1</sub> and V<sub>2</sub> varieties, respectively.
