A study of efficacy of different antibiotics for management of bacterial blight disease of pomegranate caused by Xanthomonas axonopodis pv. punicae was conducted during the year 2010-12 at College of Agriculture, Osmanabad. In vitro study revealed that antibiotic streptocycline showed maximum inhibition zone of 22.21 and 31.60 per cent at 250 and 500 ppm concentrations against X. axonopodis pv. punicae, followed by tetracycline (18.26 and 27.53 %) and bacterinol (17.40 and 27.15 %) the least inhibition of bacterial growth was observed in cefaclore (13.08 and 17.53 %), respectively. Among seven botanicals neem oil showed maximum inhibition at all concentration (5, 10, 15 and 20 %) followed by garlic, neem leaf extract, tulasi leaf extract, ginger extract, guava leaf extract and aloe vera, respectively. The bacterial antagonistic viz., Pseudomonas fluorescens and Bacillus substilis were found effective in inhibiting the test pathogen at 15.43 and 12.71 per cent, respectively. Based on the efficacy of these different antibiotics, bioagents and plant extracts, the best one were applied in integrated management schedule for mitigating bacterial blight of pomegranate. The schedule was applied at five different locations in Marathwada region of Maharashtra. At the time of adoption of orchards, the per cent disease severity observed in the orchard at Kelewadi, Wagholi, Sakanewadi, Hol and Killari were 16.44, 16.56, 17.85, 11.50 and 26.32 which was reduced to 3.5, 8.23, 8.14 and 9.53 and 9.04, respectively at harvest.Keywords

In vitro evaluation of new synthetic fungicides against Colletotrichum gloeosporioides were carried out in the Department of Plant Pathology, College of Agriculture, Osmanabad during the year 2011-12. Among the non-systemic fungicides at 0.3 per cent concentration carbendazim + mancozeb showed 82.10 per cent inhibition of mycelial growth of fungus followed by chlorothalonil with 75.80 per cent and least inhibition of mycelial growth was recorded in captan 63.48 per cent. The systemic fungicides were evaluated against the pathogen at 0.05, 0.1, 0.15 per cent concentration. Among these concentration all fungicides were significantly found superior at 0.15 per cent concentration compared to 0.1 and 0.05 per cent concentration. The maximum per cent inhibition of growth of C. gloeosporioides was observed in propiconazole (74.86%) followed by benomyl (68.17%), iprodion + carbendezim (67.67%), thiophynate methyl (64.97%). The least per cent inhibition of fungus was recorded in bittertanol (44.12%) and hexaconazole (32.62%).Keywords

The roving survey of anthracnose of pomegranate was carried out during June 2011- January 2012 in Latur and Osmanabad districts. Survey on the incidence and severity of anthracnose of pomegranate reveals the magnitude of the problem in pomegranate orchards and serves as a precursor for evolving the management strategies. It also gives clue about survival of pathogen during off season as weed or collateral hosts. In Latur district, pomegranate orchards of Latur, Chakur, Ausa, Nilanga, Renapur, Ahamdpur and Udgir tahsil were surveyed to find out the incidence and severity of anthracnose of pomegranate caused by Colletotrichum gloeosporioides (Penz.). In the surveyed orchards, the disease incidence ranged between 38.75 to 57.45 per cent. In this district the maximum incidence and severity of disease was recorded in Chakur tahsil followed by Udgir, Nilanga, Ahamdpur, Latur and Ausa. In Osmanabad district, the disease incidence ranged between 46.33 to 57.56 per cent. In this district the incidence and severity of disease was recorded maximum in Tuljapur followed by Washi, Kalamb and Osmanabad.Keywords
