Abstract: Early blight, caused by Alternaria solani (Ell. and Mart.) Jones and Grout is a serious disease of potato growing regions of Maharashtra. Several effective pesticides have been recommended against this pathogen but development of resistance of pathogenic fungi towards pesticides is a great problem that can affect significantly the efficacy of chemical fungicides. Therefore keeping in view an experiment on effect of fungicides schedules against early blight was conducted during 2018-19 and 2019-20 on potato. The experiment laid out in RBD design with four treatments and five replications. The results revealed that spray of mancozeb 75 WP @ 2.5 gm/ liter of water followed by hexaconazole 5 EC @ 0.5 ml /liter of water and then mancozeb 75 WP@ 2.5 gm/ liter of water at 10 days interval was found significantly superior in controlling the early blight of potato and also recorded significant highest yield as compared to other treatments.
