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,
Eggplant is the most traditional vegetable crop in India and susceptible to a number of diseases, among which Fusarium wilt caused by Fusarium oxysporum f.sp. melongenae (FOM) that reduce yield and quality. The present study on effect of biofumigation on Fusarium wilt of eggplant caused by Fusarium oxysporum f.sp. melongenae under natural field conditions showed that the biocidal volatiles released by Brassica tissue incorporation decreased the wilt incidence greatly from 14.57(Radish) to 50.88(Mustard) per cent reduction over control and significantly enhanced the Yield 30.43 (Radish) to 51.95 (Mustard) per cent increase over control and also enhanced the yield parameters viz., leaf area (10.15 to 35.87), plant height(13.01 to 26.39), root length(23.10 to 49.29) per cent increase over control respective.
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%).
