Abstract: Potato is one of the world's fourth most important food crop belongs to family solanaceae. More than one billion peoples consume potatoes and richest source of energy highest dry matter, energy and edible proteins. The field experiments on Efficacy of sequential sprays of different fungicides against early blight Alternaria solani (Ellis and Martin) in potato Solanum tubrosum L. was conducted during kharif season on potato (cv. K. Pukharaj) for consecutive three years. The experiment was laid out in RBD design with 6 treatments and 4 replications. The results revealed that spray of Chlorothalonil 75 WP (0.25%) @ 2.5 gm/ liter of water followed by Hexaconazole 5 EC (0.05%) @ 0.5 ml /liter of water and then Chlorothalonil 75WP (0.25%) @ 2.5 gm/liter of water at 10 days interval was found significantly superior in controlling the early blight on potato The yield differences due to spraying of fungicides were significant and the highest yield (18.10 t/ha) was obtained in same treatment.
