Management of cercospora leaf spot of sesame.

Sesame (Sesamum indicum L.) is an important oilseed crop. The crop suffers from many fungal, bacterial, viral and phytoplasma diseases in which the Cercospora leaf spot caused by Cercospora sesami infects all parts of the plant resulting into complete defoliation which leads to severe economic losses. The experiment was laid out during Kharif 2009 and 2010 using a susceptible variety DS-1 in a randomized block design with three replications at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad. The experiment results from Kharif 2009 revealed that Carbendazim @ 0.1 per cent and Quintal @ 0.1 per cent recorded lowest per cent disease index (PDI) of 48.45 and 44.41, respectively and were found at par with each other. The fungicidal spray of Quintal @0.1 per cent and carbendazim @ 0.1 per cent recorded highest yield of 470 kg/ha and 352 kg/ha, respectively. The experimental results from Kharif 2010 also revealed the same trend wherein, the fungicides, Carbendazim @0.1 per cent and Quintal @0.1 per cent recorded lowest per cent disease index of 54.00 and 49.00, respectively and were found promising in the management of Cercospora leaf spot of sesame. The pooled analysis of Kharif 2009 and 2010, the fungicides Carbendazim and Quintal were found on par with each other. However, the yield data revealed the significant difference between carbendazim (667 kg/ha) and Quintal (818 kg/ha).
