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.

    INVESTIGATIONS ON MANAGEMENT OF MULBERRY MEALY BUG MACONELLICOCCUS HIRSUTUS (GREEN) USING PLANT PRODUCTS
    (University of Agricultural Sciences GKVK, Bangalore, 41120) MADHURI, THINNALURI; BHASKAR, R N
    The study on the “Investigations on Management of Mulberry Mealy bug Maconellicoccus hirsutus (Green) using plant products” was carried out during 2010-12 at the Department of Sericulture, UAS, GKVK, Bangalore - 65. The finding revealed that, the repellent property of seed kernel extracts exerted better experimental results than their corresponding leaf extracts. In most of the case, seed kernels found effective and promising viz neem (96.53%), Pongamia (84.73%) and Mahua (74.87 %). The same trend was observed even after 48 hours of spray. In all the other treatments, repellent property of botanicals against mealy bug was increased significantly with increased exposure period. Seed kernel extract of neem was found effective in recording highest (78.67%) nymphal mortality followed by Pongamia (56.00%) and Mahua (46.67%). There was no significant decrease in tukra incidence in pre treatment count after 7 days of spray. However, the effect was found significant after 14 days of spray (2nd spray) and it was decreased more in seed kernel extracts of neem (13.12%) and Pongamia (10.67%). On the other hand in control plots, the incidence of tukra was noticed from 31.59 to 41.27 per cent which was comparatively more than botanical spray. Further, after botanical spray the affected leaves did not show any variation in moisture content, moisture loss and moisture retention capacity of M5 mulberry leaves and there was no significant difference due to botanicals sprayed on morpho-physiological parameters in the affected mulberry leaves.
