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.

    STUDIES ON SCAB OF POMEGRANATE CAUSED BY Sphaceloma punicae Bitanc.

    Scab caused by Sphaceloma punicae Bitanc. is a serious fungal disease of pomegranate. The present investigation was undertaken to know the severity of scab disease in southern Karnataka, evaluation of fungicides, bio-agents and botanicals against S. punicae. Survey revealed that, the maximum per cent disease index (PDI) of scab was observed in Tipaturu (15.56) and Kanakapura (13.65) during the survey. The pathogen was identified as Sphaceloma punicae based on pathogenicity test and morphological characterization viz., septate mycelium, conidia were 2.9–4.8 × 10.2–12.0 μm in size, ovoid to sub-cylindrical, unicellular and hyaline in nature. The maximum radial growth of pathogen (90.00 mm) was observed on oat meal agar followed by potato dextrose agar (86.43 mm). The temperature of 30 °C and pH 6.5 were found ideal for growth of the pathogen. Under in-vitro studies, the systemic fungicides viz., tebuconazole, propiconazole, thiophanate methyl and carbendazim along with combi-products viz., azoxystrobin + mancozeb, hexaconazole + zineb, fenamidone + mancozeb, and carbendazim + mancozeb at 250, 500 and 1000 ppm concentration showed completely inhibited the growth of pathogen. The contact fungicides propineb and mancozeb at 1000 ppm recorded complete inhibition of the pathogen. Among the nine plant extracts, maximum mycelial inhibition (73.63 %) was observed in garlic extract. Among the six fungal bio-agents, Trichoderma harzianum (Th-14) showed 83.15 per cent inhibition of pathogen. Whereas the bacterial bio-agent Bacillus amyloliquefaciens showed maximum mycelial inhibition of 64.60 per cent. The above fungicides can be exploited for the management of scab of pomegranate.
