Abstract
A detailed study was undertaken during 2021-23 to evaluate suitable management practices for major diseases of finger millet. Leaf blast disease was observed from 15 days after sowing (DAS) and showing an increasing trend up to 52 DAS. Whereas, Helminthosporium leaf spot was observed from 37 DAS till harvesting of the crop. Field experiments were conducted to evaluate the effect of different treatments comprises of fungicides and biocontrol agents at Centre of Excellence in Millets, Athiyandal, India and it was found that seed treatment with B. subtilis at 10g/kg of seed + spray of Azoxystrobin 25 SC @ 200 ml/ac at 25 and 40 days after sowing, was highly effective in controlling blast and Helminthosporium leaf spot after sowing was found to be very effective in controlling blast and Helminthosporium leaf spot.and recorded maximum yield when compared to other treatments and which is followed by seed treatment with B. subtilis at 10g/kg of seed + Tricyclazole 75 WP @ 500 g/Ha at 25 days after sowing.
