A present investigation for the management of purple blotch of onion (Allium cepa) was carried out at Department of Plant Pathology and Department of Vegetable Science, College of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during 2018-19. In the experiment among the different treatments, treatment (T9) i.e. bulb dip (Copper oxychloride @ 0.25% + Streptomycin @ 200 ppm) + spraying with (Mancozeb @ 0.25% + Carbendazim @ 0.10% + Copper oxychloride@ 0.25%) treatment recorded lowest per cent disease intensity i.e. 15 per cent and it showed highest per cent disease control i.e. 55.13 per cent and followed by treatment (T6) i.e. spraying with (Mancozeb @ 0.25% + Carbendazim @ 0.10% + Copper oxychloride @ 0.25%). The maximum seed yield obtained in treatment T9 i.e.1022 kg/ha which was found significantly superior over rest of the treatments and followed by T7 bulb dip (Copper oxychloride @ 0.25% + Streptomycin 200ppm) + spraying with (Mancozeb @ 0.25% + Carbendazim @ 0.10%) i.e. 1003 kg/ha. Different chemical treatments effectively controlled the onion purple blotch with increased seed yield over control in the range of 26.62 % to 68.98 %.
