abstract
Field studies were conducted to evaluate the comparative efficacy of six systemic and four non-systemic fungicides against early blight of tomato caused by Alternaria solani (Ellis and Martin). The experiments conducted during Kharif 2014 to study effect of some promising fungicides found under in vitro studies as foliar sprays against early blight of tomato. Three foliar sprays of at 15 days interval with Difenoconazole 25 EC was the most effective fungi toxicant reducing the disease incidence to 23.48 per cent from 61.23 per cent, unsprayed check. The other fungicides in order of their decreasing efficacies were Flusilazole 40 EC >Hexaconazole 5 EC >Mancozeb 75 WP. Propineb 70 WP proved least efficacious among the test fungitoxicants reducing the disease incidence to 43.70 per cent from 61.23 per cent, unsprayed check. Similarly Difenoconazole 25 EC again proved most effective fungitoxicant in case of disease intensity reducing the disease intensity to 16.39 as against 41.31 per cent observed in unsprayed check. The other fungicides in order of their decreasing efficacies were Mancozeb 75 WP >Flusilazole 40 EC >Hexaconazole 5 EC. Propineb 70 WP proved least efficacious among test fungi toxicants reducing the disease intensity to 24.11 per cent. Difenoconazole 25 EC gave the highest disease control of 61.67 and 60.32 per cent in case of disease incidence and disease intensity respectively while the least per cent disease control of 43.70 and 41.63 per cent respectively was given by Propineb 70 WP.
