Onion (Allium cepa L.) is one of the important export oriented bulb crop and used as a fresh vegetable, salad and spices. Onion is grown all over the country in which Maharashtra is a leading state occupying the first position in production. Onion crop is affected by various foliar diseases in which stemphylium blight (Stemphylium vesicarium) and purple blotch (Alternaria porri) are the major constraint in bulb production and cause severe yield loss. The field study was carried out with the objectives to evaluate the efficacy of triazole, strobilurin, benzimidazole, dithaiocarbamate and combined fungicides in sequential spray alongwith insecticides for control of foliar diseases of onion and the residue status of pesticide in onion bulbs after harvest of onion. The trial was conducted on onion variety Agrifound Dark Red at Regional Research Station, NHRDF, Nashik, Maharashtra during kharif 2018, and 2019. The pooled data of two years revealed that, the combined spray of different fungicide groups with insecticides Pyraclostrobin+Metiram @ 0.25% + Deltamethrin @ 0.1% at 30 DAT, Trifloxistrobin+Tebuconazole @ 0.1% + Cyperpethrin @ 0.1% at 45 DAT, Zineb+Hexaconazole @ 0.25% + Fipronil @ 0.1% at 60 DAT, Carnebdazim+Mancozeb @ 0.25%+Curacron @ 0.1% at 75 DAT performed better for management of foliar diseases with percent disease control of stemphylium blight (61.15%) and purple blotch (43.50%) over untreated control. The onion bulbs were found free from pesticide residue tested after harvesting in NABL accredited Laboratory, NHRDF, Chitegaon, Nashik.
