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.

    ISOLATION AND CHARACTERIZATION OF ENTOMOPATHOGENIC FUNGI AND THEIR EFFECTIVENESS
    (University of Agricultural Sciences GKVK, Banglore, 2007-08-30) BHARATHI, H. TALWAR; J. H. KULKARNI
    An attempt was made to isolate and characterize native entomopathogenic fungi. Nine insect mycopathogens, belonging to seven genera were found naturally occurring in the nine districts of Northern Karnataka. Morphological variation among the field collected isolates of M. anisopliae (Ma2) and V. lecanii (VI1) for various parameters like, hyphal and conidial characters, sporulation and spore yield were recorded. Pathogenicity of V. lecanii to aphids, whitefly and mites and that of M. anisopliae to Americain bollworms £ind rhinocerous beetle was proved in laboratory. Among different carbon sources tested, starch proved superior for both the mycopathogens NH4 (SO4) and KNO3 were superior as nitrogen source. Bajra and rice grains served as most productive media for conidial growth of Ma2 and Vll with an yield of 22.77 x 10^ and 24.59 x 10® conidia per g of media, respectively. Among pesticides tested, fungicides showed maximum inhibition followed by insecticides and weedicides. The persistence of mycopathogens (Ma2 and Vll) was higher in soil (upto 16 months) than in phylloplane (upto 3 months). In general, all the carrier material had more conidial viability when stored in refrigerated and deep freezer condition and a reduction of more than 10 per cent and 8 per cent in refrigerated and deep fereezer was observed after 150 DAS respectively. Oil formulations proved better than wettable powder.
