Abstract: The efficacy of chemicals; Tebuconazole and Mancozeb as well as Pseudomonas fluoroscens as a bioagent for seed treatment followed by foliar spray with chemicals Hexaconazole, Tebuconazole, bioagent Pseudomonas fluoroscens; plant extracts such as NSKE and neem oil were studied for the management of major foliar diseases such as late leaf spot and rust in groundnut. Field trials were conducted for three consecutive seasons of kharif 2013, 2014 and 2015 in the experimental site of AICRP on groundnut, O.U.A.T., Bhubaneswar, Odisha. The trial was laid out in Randomised Block Design with four replications. The row to row spacing was 30cm and plant to plant spacing of 10cm was adopted in plot size of 15.3m2 (5.1mx3m) with a recommended fertilizer dose of N:P2O5:K2O::20:40:40 kg/ha. The seed treatment with Tebuconazole (1.5g/kg) followed by two foliar spray with Tebuconazole @1ml/lit proved to be most efficacious which recorded the least PDI of 26.4 and 15.05 for LLS and Rust disease respectively; with the highest pod yield of 1880 kg/ha and ICBR of 1:6.28. Seed treatment with Mancozeb @ 2g/kg followed by foliar spray of Hexaconazole proved to be the next best treatment which recorded PDI of 30.07 and 19.13 against LLS and Rust respectively with a pod yield of 1766 kg/ha. The seed treatment with Pseudomonas fluorescens followed by foliar spray with either neem oil or NSKE was also found effective when compared against the untreated control.
