University of Agricultural Sciences, Bengaluru

University of Agricultural Sciences Bangalore, a premier institution of agricultural education and research in the country, began as a small agricultural research farm in 1899 on 30 acres of land donated by Her Excellency Maharani Kempa Nanjammanni Vani Vilasa Sannidhiyavaru, the Regent of Mysore and appointed Dr. Lehmann, German Scientist to initiate research on soil crop response with a Laboratory in the Directorate of Agriculture. Later under the initiative of the Dewan of Mysore Sir M. Vishweshwaraiah, the Mysore Agriculture Residential School was established in 1913 at Hebbal which offered Licentiate in Agriculture and later offered a diploma programme in agriculture during 1920. The School was upgraded to Agriculture Collegein 1946 which offered four year degree programs in Agriculture. The Government of Mysore headed by Sri. S. Nijalingappa, the then Chief Minister, established the University of Agricultural Sciences on the pattern of Land Grant College system of USA and the University of Agricultural Sciences Act No. 22 was passed in Legislative Assembly in 1963. Dr. Zakir Hussain, the Vice President of India inaugurated the University on 21st August 1964.

    PHYLLOPLANE MYCOFLORA OF MULBERRY - A SOURCE OF INOCULUM TO ASPERGILLOSIS OF SILKWORM AND THEIR MANAGEMENT THROUGH BOTANICALS
    (University of Agricultural Sciences GKVK, Bangalore, 2009-02-02) SARITHA KUMARI, S.; BHASKAR, R. N.
    The studies on the “Phylloplane mycoflora of mulberry - a source of inoculum to Aspergillosis of silkworm and their management through botanicals” was carried out during 2007–09 at the Department of Sericulture, UAS, GKVK, Bangalore-65. The study indicated that, the spatial distribution pattern of all the three species (Aspergillus flavus, Aspergillus niger & Aspergillus terreus) of Aspergillus was very vivid with height of the plant before and after rain in all the three mulberry ecosystems studied (Kolar {Row system}, Ramanagaram and GKVK {Pit system}). The spatial distribution pattern of A. flavus was more restricted to 15cm (2.67nos/ml) above the ground level compared to other two species of Aspergillus. The in-vitro efficacy of botanical extracts on inhibition zone of Aspergillus revealed significant results. The stock solution of Phyllanthus niruri registered maximum zone of inhibition of 11.02mm followed by Adathoda vasica and Terminalia arjuna. The in-vivo effect of botanical extracts on first, second and third instar inoculated lots of PMxCSR2 and their subsequent growth revealed significant results. However, P. niruri administered batches was recorded increased larval weight (0.030, 0.113 and 0.598g/10), reduced moulting duration (19.85, 19.98, 22.03 and 31.63h), more ET50 (28.78, 50.33 and 73.00hrs) and increased ERR (79.78, 78.89 and 78.00%), spinning (85.11, 85.11 and 84.00%) and all the cocoon and post cocoon parameters. Among three species of Aspergillus sprayed on I-IIIrd instar larvae there was a significant difference with respect to larval, cocoon and post cocoon parameters. Further, the highest larval weight (0.028, 0.106 and 0.615g/10), reduced moulting duration (19.76, 19.88, 21.14 and 31.33h), ERR (75.50, 77.17 and 78.83%), spinning (82.00, 84.50 and 84.50%), cocoon (1.70, 1.71 and 1.72g), shell (0.29, 0.28 and 0.29g), pupal weights (1.35, 1.35 and 1.36g), shell ratio (16.87, 16.69 and 16.63%), silk productivity (3.59, 3.56 and 3.53cg/day), filament length (872.50, 880.02 and 878.02m) and eclosion (69.17, 74.17 and 76.67%) were observed with A. terreus batches followed by A. niger and A. flavus. Whereas, A. flavus registered comparatively less ET50 for symptom expression (25.83, 46.33 and 72.00h) and found highly pathogenic to all the three instars, respectively.
