An experiment was carried out at Kittur Rani Channamma College of Horticulture, Arabhavi, (UHS, Bagalkot) during Kharif 2012 and Kharif 2013 to find out the effect of vesicular arbuscular mycorrhiza and bio-inoculants on purple blotch disease and cost economics in onion. Per cent disease index for purple blotch differed significantly due to bio-inoculants levels in both the years as well in pooled data. In the pooled data significantly lower per cent disease index at 90 days after transplanting (21.61) was recorded by the treatment T10, followed by the treatment T11 and T9. The treatment T10 resulted significantly higher B:C ratio (2.75) in the pooled data.

Per cent disease index for purple blotch differed significantly due to bio-inoculants levels in both the years as well in pooled data. In the pooled data significantly lower per cent disease index at 90 days after transplanting (21.61) was recorded by the treatment T10, followed by the treatment T11 and T9.
