Kodo millet (Paspalum scrobiculatum L.) is an important ancient millet crop, which is believed to originate from African subcontinent and was domesticated in India approximately 3000 years ago. It belongs to family Poaceae, is self-pollinating crop and has chromosome no. 2n = 4x = 40. It is hardy, small seeded, climate resilient crop, which thrives well in different ecological conditions. Kodo is infected by a number of pathogens which includes fungi, bacteria, viruses, etc. Leaf blight is becoming a major concern these days, which is caused by Alternaria spp. and Helminthosporium spp. (Bipolaris spp.). Alternaria tenuissima, which is responsible for causing leaf blight of kodo millet have gained immense importance these days as the disease is becoming a major concern now. In our experiment, eight plant extracts were used viz., garlic, ginger, Aloe vera, marigold, turmeric, neem, congress grass and Calotropis along with control were used at 5% and 10% concentrations. The garlic extract gave the best inhibition at both 5% and 10% of 45.5% and 51.1% with poor and with no conidial production, respectively. Among fungicides, single and combo fungicides namely, Tebuconazole 5.36%, Metalaxyl 35% WS, Carbendazim 50% WP, Carboxin 37.5% + Thiram 37.5% DS, Carbendazim 12% + Mancozeb 63% WP, Metalaxyl 8% + Mancozeb 64% WP and Difenoconazole 25% EC along with control were used at100, 250 and 500 ppm. Difenoconazole 25% gave best results all 3 concentrations of 69.5% 71.9% and 84.7% with no conidial production.
